[0039] The embodiment of the present invention provides a method and related device for obtaining a browser uniform resource locator, which is used to detect new access events of the browser by setting a hook function. This method of setting a hook function does not need to inject an external function into the browser process, thereby avoiding the potential interference of the external function on the running process of the browser process, and improving the security of the process of obtaining the browser uniform resource locator URL.
[0040] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0041] The terms "first", "second", "third", "fourth", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0042] An embodiment of the present application provides a method for obtaining a browser uniform resource locator, the general principle of the method is: when it is necessary to obtain the uniform resource locator URL of the browser (wherein the URL is commonly known as the web page address, which is a standard resource address on the Internet and is also called a uniform resource locator), obtain the browser process identifier; set a hook function for a new access event of the browser according to the browser process identifier; if the hook function detects a new access event, obtain the type of the browser and the root UI element in the browser window; obtain the first UI element object tree to which the root UI element belongs; according to the type of the browser, retrieve the child UI elements of the preset control type in the first UI element object tree, the preset control type includes a document control type, a toolbar control type or an editable control type; obtain a control object whose control type is IUIAutomationLegacyIAccessiblePattern among the controls included in the child UI element; obtain the value of the control object, and determine the browser uniform resource locator with the value of the control object. Because the method for obtaining the browser uniform resource locator provided by the present application detects the new access behavior of the browser by setting a hook function for the new access event of the browser, and this method of setting the hook function is different from the method of injecting peripheral functions into the browser process in the prior art, thereby avoiding the potential interference with the operation of the browser process caused by the injection of peripheral functions, and improving the stability of the browser process operation in the process of obtaining the browser URL.
[0043] In order to better implement the above method for obtaining the browser uniform resource locator, the present application embodiment provides a system for obtaining the browser uniform resource locator. Figure 1 , Figure 1A schematic diagram of the architecture of a system for obtaining a browser uniform resource locator provided in an embodiment of the present application. The system may include at least one terminal device 101 and a server 102; different types of browsers may be installed on the terminal device 101, such as Google Chrome, Sogou Browser, Firefox, or IE browser. Server 102 may be used to receive access events of the browser installed in the terminal device 101. Server 102 may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms, etc.
[0044] Among them, the above-mentioned method for obtaining the browser uniform resource locator is executed by the terminal device 101. When the terminal device 101 needs to obtain the URL of the browser, the browser process identifier is obtained; a hook function is set for a new access event of the browser according to the browser process identifier; if the hook function detects a new access event, the type of browser and the root UI element in the browser window are obtained; the first UI element object tree to which the root UI element belongs is obtained; according to the type of browser, the child UI elements of the preset control type in the first UI element object tree are retrieved, and the preset control types include document control types, toolbar control types or editable control types; the control objects whose control types are IUIAutomationLegacyIAccessiblePattern in the controls included in the child UI elements are obtained; the value of the control object is obtained, and the value of the control object is used to determine the browser uniform resource locator.
[0045] For ease of understanding, the following describes the method for obtaining the browser uniform resource locator in this application. Figure 1 , an embodiment of the method for obtaining a browser uniform resource locator in an embodiment of the present application includes:
[0046] 201. Get the browser process ID;
[0047] Specifically, when the embodiment of the present application is executed by a terminal device, that is, a client, the client needs to obtain the uniform resource locator URL of the browser, and then first obtains the process identifier of the browser.
[0048] Among them, the browser process, also known as the rendering process or UI rendering process, is one of the core components of a web browser. Each browser usually has one or more such processes, which are responsible for parsing HTML documents, loading CSS styles, executing JavaScript code, and presenting web page content to users. When a browser opens a new tab or window, the browser will start a new process to process this page, which can maintain the independence and parallelism of each page and prevent the crash of one page from affecting other pages.
[0049] Furthermore, the browser process identifier is an identification code set for each browser process, so as to identify the process of each browser, wherein the browser process is generally identified by PID, and the browser process identifier PID can be viewed and obtained through the task manager.
[0050] 202. Setting a hook function for a new access event of the browser according to the browser process identifier;
[0051] After the process identifier PID of the browser is obtained, a hook function may be set for a new access event of the browser process through setWinEventHook, wherein the new access event of the browser refers to a new web page access event or an upload or download event of the browser.
[0052] Furthermore, when setting a hook function for a new access event of the browser process, parameter 5 of the hook function setWinEventHook can be set to the browser process, and parameter 7 of the hook function setWinEventHook can be set to a combination of constants WINEVENT_OUTOFCONTEXT and WINEVENT_SKIPOWNPROCESS. When parameter 7 of the hook function setWinEventHook is set to a combination of constants, it means that the hook function will not be mapped to the address space of the browser process that generates the event, thereby avoiding blocking the operation of the browser process.
[0053] 203. If the hook function detects a new access event, the type of the browser and the root UI element in the browser window are obtained through the UI automation interface;
[0054] Specifically, if the hook function detects a new access event, the client obtains the type of browser and the root UI (User Interface) element in the browser window.
[0055] Among them, when the client obtains the browser type, it is executed in the following way: the client can pre-store and maintain a mapping relationship table between the browser type and the browser process identifier. After obtaining the browser process identifier, the browser process identifier can be used to query the above mapping relationship table to obtain the browser type.
[0056] As for the process of further obtaining the root UI element in the browser window, it will be described in the following embodiments and will not be repeated here.
[0057] 204. Obtain the first UI element object tree to which the root UI element belongs;
[0058] After obtaining the root UI element in the browser window, you can query the first UI element object tree to which the root UI element belongs. The first UI element object tree stores a tree structure with the root UI element as the root, so that you can easily query and obtain the child UI elements in the root UI element. For easy understanding, Figure 3 A schematic diagram of the first UI element object tree is given.
[0059] 205. According to the type of the browser, retrieve the child UI element of the preset control type in the first UI element object tree, where the preset control type includes a document control type, a toolbar control type, or an editable control type;
[0060] After obtaining the first UI element object tree, the sub-UI elements of the preset control type in the first UI element object tree can be retrieved according to the type of browser, wherein the preset control type includes a document control type, a toolbar control type or an editable control type.
[0061] Specifically, because the types of browsers are different, when obtaining sub-UI elements, sub-UI elements of different types are correspondingly obtained. As for the relationship between the browser type and the sub-UI element type, it will be described in the following embodiments and will not be repeated here.
[0062] 206. Get the control object whose control type is IUIAutomationLegacyIAccessiblePattern from the controls included in the child UI element;
[0063] After obtaining the child UI elements of different control types in step 105, because the browser URL must be stored in the control object whose control type belongs to IUIAutomationLegacyIAccessiblePattern under the child UI element, the embodiment of the present application can obtain the control object whose control type is IUIAutomationLegacyIAccessiblePattern in the controls included in the child UI element.
[0064] Specifically, when obtaining a control object of type IUIAutomationLegacyIAccessiblePattern, the IUIAutomationElement::GetCurrentPatternAs method of the child UI element may be called to retrieve the control pattern interface identified as LegacyIAccessible in the child UI element, and then the control pattern interface of LegacyIAccessible may be used to obtain the control object of type IUIAutomationLegacyIAccessiblePattern.
[0065] 207. Get the value of the control object, and determine the browser uniform resource locator based on the value of the control object.
[0066] After obtaining a control object of type IUIAutomationLegacyIAccessiblePattern, the value of the control object is the browser uniform resource locator.
[0067] As an optional embodiment, when obtaining the value of the control object, the value of the control object of type IUIAutomationLegacyIAccessiblePattern may be obtained by calling the IUIAutomationLegacyIAccessiblePattern::get_CurrentValue method, and the value of the control object may be further determined as the uniform resource locator of the browser.
[0068] In an embodiment of the present application, a browser process identifier is obtained; a hook function is set for a new access event of the browser according to the browser process identifier; if the hook function detects the new access event, the type of the browser and the root UI element in the browser window are obtained through the UI automation interface; the first UI element object tree to which the root UI element belongs is obtained; according to the type of the browser, child UI elements of a preset control type in the first UI element object tree are retrieved, and the preset control type includes a document control type, a toolbar control type or an editable control type; a control object whose control type is IUIAutomationLegacyIAccessiblePattern among the controls included in the child UI element is obtained; the value of the control object is obtained, and the value of the control object is used to determine the browser uniform resource locator.
[0069] Because the embodiment of the present application monitors new access events of the browser by setting a hook function for the browser process, and when a new access event of the browser is monitored, the browser type and the root UI element in the browser window are obtained through the UI automation interface of the browser, and the browser uniform resource locator is finally obtained by using the root UI element. Because the present application avoids the process of injecting peripheral functions into the browser process in the prior art by setting a hook function, thereby avoiding the potential interference with the running process of the browsing process caused by the injection of peripheral functions, thereby improving the security of the process of obtaining the browser uniform resource locator.
[0070] based on Figure 2 In the embodiment described above, the process of obtaining the root UI element in the browser window through the UI automation interface in step 203 is described in detail below. Figure 4 , Figure 4 The detailed steps for obtaining the root UI element in the browser window through the UI Automation interface are as follows:
[0071] 401. Obtain the window handle of the browser from the hook function;
[0072] Because the window handle needs to be set in the hook function when setting the hook function, the embodiment of the present application can read the window handle carried by the hook function from the hook function.
[0073] Among them, the window handle is the memory address or pointer used by the operating system to uniquely identify a window, usually an integer or a specific data structure. It is a bridge between the browser and the window it creates, allowing the browser to control various properties of the window through the handle, such as maximizing, minimizing, closing, etc. In the Windows operating system, the window handle is often used for window message transmission and management.
[0074] 402. Determine whether the hook function detects a new access event for the first time. If so, execute step 403. If not, execute step 404.
[0075] Because when obtaining the root UI element of the browser window, the UI automation interface needs to be used, and when using the UI automation interface, a global singleton UI automation object needs to be created first. If the hook function detects a new access event for the first time, there is no global singleton UI automation object in the browser. Therefore, if the hook function detects a new access event for the first time, step 403 needs to be executed. If it is not the first time to detect a new access event, step 404 is executed.
[0076] 403. Generate a global singleton UI automation object;
[0077] Specifically, if the hook function detects a new access event for the first time, because there is no global singleton UI automation object in the browser, it is necessary to create a global singleton UI automation object first, which can be created through the following process:
[0078] First, call the CoInitialize function to initialize the current thread of the browser, and then call CoCreateInstance to generate a global singleton UI automation object of type IUIAutomation.
[0079] 404. Query the UI automation elements in the browser window using the window handle of the browser and the submethod of the global singleton UI automation object;
[0080] If the hook function is not detecting a new access event for the first time, it means that a global singleton UI automation object has been created in the browser. Then, the UI automation element in the browser window is queried using the browser window handle and the submethod of the global singleton UI automation object.
[0081] Specifically, after obtaining the global singleton UI automation object, the IUIAutomation::ElementFromHandle method of the global singleton UI automation object and the window handle of the browser can be called to retrieve the UI automation element in the browser window. After obtaining the UI automation element, the UI automation element is determined as the root UI element in the browser window.
[0082] 405. Determine the UI automation element as the root UI element.
[0083] After the UI automation element is obtained, the UI automation element is determined as the root UI element in the browser window.
[0084] The embodiment of the present application describes in detail the process of obtaining the root UI element in the browser window, and the embodiment of the present application obtains the root UI element in the browser window through a UI automation interface, thereby improving the convenience of obtaining the root UI element in the browser window.
[0085] based on Figure 2 The following describes in detail the method for obtaining the browser uniform resource locator. Figure 5 , Figure 5 Another embodiment of the method for obtaining a browser uniform resource locator:
[0086] 501. Get the browser process ID;
[0087] 502. Setting a hook function for a browser window top event or a browser window name change event according to the browser process identifier;
[0088] Specifically, in order to facilitate the monitoring of new access events of the browser window, we can usually monitor the browser's window top event and / or the browser's window name change event. Because generally when the browser's window top event and / or the browser's window name change event occurs, it can be determined with a high probability that a new window access event has occurred in the browser or an upload or download event has occurred in the browser.
[0089] Therefore, as an optional embodiment, a hook function may be set for the browser window top event or the browser window name change event, wherein the method of setting the hook function is similar to that described in step 202 and will not be repeated here.
[0090] 503. Obtain the window handle of the browser from a hook function that monitors the browser window top event or the browser window name change event;
[0091] After setting a hook function for a browser window top event or a browser window name change event, because the hook function carries the browser window handle, the embodiment of the present application can obtain the browser window handle from the hook function.
[0092] Because when a window pinning event or a window name change event occurs in the browser, it may not be a new access event that occurs in the browser. Therefore, in order to improve the event processing efficiency, the embodiment of the present application can also judge the correspondence between the browser window pinning event or the browser window name change event and the browser new access event through the following steps. Therefore, when it is determined that a new browser access event has occurred, the step of obtaining the browser uniform resource locator is executed, otherwise the hook function event is skipped to avoid wasting the computer's processing resources.
[0093] 504. According to the window handle of the browser, query the window class name corresponding to the window handle of the browser;
[0094] Specifically, as an optional embodiment, when determining the correspondence between the browser window top event or the browser window name change event and the browser new access event, the window class name corresponding to the browser window handle can be queried based on the browser window handle. The window class name is the type of the window handle.
[0095] 505. According to the window handle of the browser, query the browser process identifier corresponding to the window handle of the browser;
[0096] After obtaining the window handle of the browser, you can further obtain the browser process ID corresponding to the window handle.
[0097] As a specific embodiment, the GetWindowThreadProcessId interface may be queried according to the window handle, thereby obtaining the browser process identifier corresponding to the window handle.
[0098] 506. According to the browser process identifier, query the browser type corresponding to the browser process identifier;
[0099] After obtaining the process identifier of the browser, the mapping relationship table between the browser process identifier and the browser type stored in the client can be further queried to obtain the browser type corresponding to the browser process identifier.
[0100] 507. According to the browser type, obtain the window class name preset by the browser type;
[0101] Because each type of browser is provided with a preset window class name, an embodiment of the present application may compare the window class name queried using the browser window handle with the preset window class name corresponding to the browser type. If the two are the same, it means that the browser window pinning event and / or the browser window name changing event is indeed a new browser access event, and step 508 is executed; if the two are different, it means that the browser window pinning event and / or the browser window name changing event is not a corresponding new browser access event, and step 509 is executed.
[0102] 508. If the window class name corresponding to the window handle of the browser is the same as the window class name preset for the browser type, it is determined that a new access event has occurred in the browser window, and step 510 is triggered;
[0103] If the window class name queried using the browser window handle is the same as the preset window class name corresponding to the browser type, it is determined that a new access event has occurred in the browser window, and step 510 is triggered to continue to obtain the browser's uniform resource locator.
[0104] 509. If the window class name corresponding to the window handle of the browser is different from the window class name preset for the browser type, it is determined that no new access event occurs in the browser window, and the hook function monitoring event is terminated.
[0105] If the window class name queried using the browser window handle is different from the preset window class name corresponding to the browser type, it is determined that no new access event occurs in the browser window, and the hook function monitoring event is terminated.
[0106] 510. If the hook function detects a new access event, the type of the browser and the root UI element in the browser window are obtained through the UI automation interface;
[0107] 511. Obtain the first UI element object tree to which the root UI element belongs;
[0108] 512. According to the type of the browser, retrieve the child UI element of the preset control type in the first UI element object tree, where the preset control type includes a document control type, a toolbar control type, or an editable control type;
[0109] 513. Get the control object whose control type is IUIAutomationLegacyIAccessiblePattern from the controls included in the child UI element;
[0110] 514. Get the value of the control object, and determine the browser uniform resource locator based on the value of the control object.
[0111] It should be noted that steps 510 to 514 are similar to Figure 2 The descriptions of step 203 to step 207 in the embodiment are similar and will not be repeated here.
[0112] In an embodiment of the present application, the correspondence between the browser window pinning event and / or the browser window name change event and the browser new access event is further determined by comparing the window class name, and when it is further determined that a browser new access event has occurred, the browser's uniform resource locator is further obtained. When a browser new access event has not occurred, the hook event is terminated, thereby improving the processing efficiency of the entire event and avoiding the waste of processor resources in the client.
[0113] based on Figure 2 In the embodiment described above, the process of retrieving the sub-UI elements of the preset control type in the first UI element object tree according to the type of the browser is further described in detail below:
[0114] 1. If the browser types include: Google Chrome and / or Sogou Browser;
[0115] See also Figure 6 , Figure 6 A refinement of step 205:
[0116] 601. If the browser type includes Google Chrome and / or Sogou Browser, calling a submethod of the global singleton UI automation object to create a search condition for searching the document control type;
[0117] If the browser is Google Chrome and / or Sogou Browser, the child UI elements belonging to the document control type in the first UI element object tree are retrieved, so it is necessary to first call the child method of the global singleton UI automation object to create a retrieval condition for retrieving the document control type.
[0118] As a specific implementation, when creating a retrieval condition for retrieving a document control type, the embodiment of the present application may call the IUIAutomation::CreatePropertyCondition method of the UI automation object and set the parameters of the method to the numbers UIA_ControlTypePropertyId and 0xC36E (indicating the document control type), thereby obtaining the retrieval condition for retrieving the document control type.
[0119] 602. Retrieve the first child UI element of the document control type in the first UI element object tree by using the retrieval condition for retrieving the document control type and the child method of the root UI element.
