Description

Technical Field

[0001] The present invention relates to the technical field of page loading, and in particular to a method and device for monitoring loading progress. Background Art

[0002] During the development of a client, when a user browses a client or a web page, it is often necessary to load a page. When loading a page, if there are many resources to be loaded (such as pictures, texts, controls, etc.) or the network quality is poor, the loading process is relatively slow, making it impossible for users or developers to accurately know the current loading progress, thus bringing a poor user experience.

[0003] In the prior art, a progress indicator scheme is adopted to enable users or developers to know the current loading progress, but the data of the existing progress indicator is not accurate enough. For example, the data is 10% at the moment when it is just loaded and suddenly becomes 100%, which cannot accurately reflect the data loading process and also brings a poor user experience.

[0004] Therefore, how to monitor the loading progress in real time and accurately is a technical problem that needs to be solved urgently at present. Summary of the Invention

For those of ordinary skill in the art, without creative efforts, other accompanying drawings can also be obtained based on these drawings.

[0096] Figure 2 is a schematic structural diagram of a loading progress monitoring device provided by an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0097] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the embodiments of the present invention.

[0098] Please refer to Figure 1 , Figure 1 is a flowchart of a loading progress monitoring method provided by an embodiment of the present invention, specifically including steps 101 to 107. This method can be applied to the loading progress monitoring of conventional web pages and can also be used for the loading progress monitoring of client pages.

[0099] Step 101: Obtain the current number of loading tasks for the current loading request according to the function call situation of the loading tasks.

[0100] The function of this step is to initially obtain the current number of all loading tasks to be executed in the current loading request.

[0101] Specifically, the respondsToSelector function can be used to implement the operation of this step. The respondsToSelector function can throw out the task event that needs to start loading currently, so as to obtain the number of current loading tasks that need to be executed in this loading request.

[0102] Specifically, the respondsToSelector function can throw out the task event that needs to start loading currently, so as to obtain the number of current loading tasks that need to be executed in this loading request.

[0103] Specifically, the respondsToSelector function is a system function. In this step, when a task event of a certain loading starts, by calling this function, the event can be called back.

[0104] Step 102, determine whether the page start loading function is called.

[0105] The function of this step is: to calculate the call of the webView control in the tasks that need to be loaded in this loading request, so that the number of current loading tasks that need to be executed in this loading request is more accurate.

[0106] Specifically, the webViewDidStartLoad function can be used as the page start loading function. Since when the page is loaded, the webViewDidStartLoad function will be called frequently to complete the loading task by using the webView control in the webViewDidStartLoad function, this step counts the number of calls of the webViewDidStartLoad function to more accurately count the number of current loading tasks that need to be executed in this loading request.

[0107] Specifically, the webViewDidStartLoad function is a system function that will be called when the webview starts to load.

[0108] Step 103, if so, increase the number of the current loading tasks, and return to Step 103.

[0109] The function of this step is: to count the number of calls of the page start loading function, so that the number of current loading tasks that need to be executed in this loading request is more accurate.

[0110] Specifically, if the webViewDidStartLoad function is called, the number of the current loading tasks will be incremented by 1 to increase the number of current loading tasks. By repeatedly judging the call situation of the webViewDidStartLoad function, the total number of tasks that need to be loaded in this loading request can be accurately counted.

[0111] Step 104, if not, then start monitoring the progress of the current loading request.

[0112] The function of this step is: through this step, officially start monitoring the loading progress.

[0113] Specifically, when the webViewDidStartLoad function is not called, it means that the current number of loading tasks has reached the maximum value, and at this time, it can be regarded as completing the statistics of the current number of loading tasks.

[0114] Through the operations of Step 101 to Step 104, the total number of tasks to be loaded in the current loading request can be accurately counted. This process belongs to the preparatory work before starting to monitor the loading progress, and then, according to the completion situation of the specific loading tasks, the loading progress of the page can be obtained in real time.

[0115] Step 105, continue to judge whether the page stop loading function is called according to the progress of the current loading request.

[0116] The function of this step is: count the call situation of the page end loading function, accurately know the completion situation of the current loading task, so as to accurately obtain the current loading progress.

[0117] Specifically, the webViewDidFinishLoad function can be used as the page end loading function. Since the webViewDidFinishLoad function will be called after the webViewDidStartLoad function is called, by counting the number of calls of the webViewDidFinishLoad function, the completion situation of the current loading task can be accurately known, so as to accurately obtain the current loading progress.

[0118] Specifically, the webViewDidFinishLoad function is a system function, and this function will be called when the webview finishes loading.

[0119] Step 106, if the webViewDidFinishLoad function is called, then reduce the current number of loading tasks.

[0120] The function of this step is: through updating the current number of loading tasks, realize the real-time monitoring of the loading progress.

[0121] Specifically, if the webViewDidFinishLoad function is called, then subtract 1 from the current number of loading tasks to update the current number of loading tasks.

[0122] Step 107: Update the progress displayed in the progress display control of the current page according to the reduced current number of loading tasks in Step 106.

[0123] The function of this step is to display the current loading progress on the page and accurately inform the user of the current loading progress.

[0124] Specifically, this step of operation can be implemented through the incrementProgress function.

[0125] Specifically, the incrementProgress function is a system function. When called, it will increase the current progress value according to the requirements and visually display the increased current progress value. Depending on the control, it can be displayed as a percentage number or as an image of a progress bar, etc.

[0126] To facilitate the monitoring of the entire loading process, the present invention also provides the following solution:

[0127] Before the said Step 101, the method further includes:

[0128] Step 21: Call the addObserver function to construct a progress observer; wherein, the callback processing parameter of the progress observer is the webView control, the KeyPath parameter of the progress observer is the estimatedProgress function, and the observed value parameter of the progress observer includes the old value and the new value of the estimatedProgress function.

[0129] Specifically, the callback processing parameter of the progress observer is used to call back the current webView control to the webView control; the KeyPath parameter of the progress observer is the estimatedProgress function, and the estimatedProgress function can determine whether the loading progress may change and make a callback through KeyPath; the observed value parameter of the progress observer is a numerical value of a dictionary type (OptionNew|OptionOld), and this dictionary contains the monitored value of the estimatedProgress function, and this value includes the old value and the new value of the change. There will be a callback every time the estimatedProgress function changes, and the estimatedProgress of the webView can be obtained in this callback.

[0130] Of course, in practical applications, multiple identical loading requests may be received within a short period of time. If the execution progress monitoring is carried out without any recognition, a large amount of computing power will be wasted and useless work will be done. To avoid this situation and improve the efficiency of progress monitoring, before step 101, the present invention also adopts the following solution:

[0131] Step 31: Obtain the URL of this loading request.

[0132] The function of this step is to quickly determine whether this loading request has been executed by comparing the URLs.

[0133] Specifically, call the shouldStartLoadWithRequest function, obtain the request parameter in the shouldStartLoadWithRequest function, and then obtain the URL of this loading request according to the request parameter.

[0134] Specifically, the shouldStartLoadWithRequest function is a system function in the WebView mode, which can implement a proxy method. When loading an HTTP protocol request, by calling this function, the parameters related to the HTTP protocol request can be called back to obtain the request parameter.

[0135] Specifically, this loading request includes an HTTP protocol request, and the request parameter is a parameter of the shouldStartLoadWithRequest function. In this step, the shouldStartLoadWithRequest function is used to obtain the request parameter included in the HTTP protocol request, and the response URL of this loading request is recorded in this parameter; the URL (Uniform Resource Locator) is simply the address of a standard resource on the Internet, and through it we can obtain the resources we need (such as web pages, pictures, audio and video, services, files, etc.).

[0136] Step 32: Obtain the URL of the currently successfully loaded page.

[0137] The function of this step is to quickly determine whether this loading request has been executed by comparing the URLs.

[0138] Specifically, the URL of the currently successfully loaded page is the URL corresponding to the last successful load, indicating that all tasks of the last loading request in this URL have been completed.

[0139] Step 33: Determine whether the URL of the current loading request is the same as the URL of the currently successfully loaded page.

[0140] The purpose of this step is to accurately determine the tasks that really need to be loaded in the current loading request by comparing with the URL of the current loading request.

[0141] Specifically, when the page is loaded, resources set in advance need to be loaded at a fixed position. Therefore, there are loading tasks in the current loading request in the URL. However, if one or more loading tasks in the current loading request have been completed after the last successful load, there is no need to load them again during the actual task loading. By using the URL of the currently successfully loaded page, the tasks that really need to be loaded can be found, improving the efficiency of progress monitoring.

[0142] When the URL of the current loading request is the same as the URL of the currently successfully loaded page, it means that all tasks of the current loading request have been completed last time, and thus the current request can be resolved.

[0143] Step 34: If the URL of the current loading request is the same as the URL of the currently successfully loaded page, call the completeProgress function to end the current loading request.

[0144] The purpose of this step is to quickly end the current loading request by using the completeProgress function.

[0145] Specifically, the completeProgress function is a system function used to resolve the current loading request and display that the progress is completed by calling when the progress is finished.

[0146] Step 35: Call the incrementProgress function to update the progress displayed in the progress display control to the state where the loading is completed.

[0147] The purpose of this step is to visually display the result that the progress has been loaded by using the incrementProgress function, facilitating the user to know in time.

[0148] Step 36: If the URL of the current loading request is not the same as the URL of the currently successfully loaded page, proceed to step 101.

[0149] The purpose of this step is to avoid meaningless progress monitoring by adding steps 31 to 36 before step 101, thereby improving the efficiency of progress monitoring.

[0150] Of course, during the loading and execution process, loading errors may occur. The present invention also provides a processing solution for such situations to accurately obtain the real-time progress of each loading stage, specifically as follows:

[0151] After step 105, the method further includes:

[0152] Step 41, determine whether exception handling occurs during the execution of the current loading request.

[0153] The function of this step is to determine whether a loading exception occurs.

[0154] Step 42, if so, subtract 1 from the current loading task count to reduce the current loading task count.

[0155] The function of this step is to take the loading exception situation into account in the actual loading process to improve the accuracy of loading process monitoring.

[0156] Step 43, according to the reduced current loading task count in step 42, call the incrementProgress function to update the progress displayed in the progress display control.

[0157] The function of this step is to timely display the current process in a visual form to facilitate the user to know the current loading process in real time.

[0158] After that, if it is found that the page appears in an abnormal inactive loading state such as being stuck, it is necessary to end the current process monitoring in a timely manner. The specific solution is as follows:

[0159] After step 43, the method further includes:

[0160] Step 51, obtain the first loading state of the current page according to the stringByEvaluatingJavaScriptFromString function.

[0161] The function of this step is to determine the current loading state of the current page.

[0162] Specifically, the first loading state includes two states: active and inactive. The active state indicates that the current page is performing a loading task, and the inactive state indicates that the current page is in an abnormal situation such as being stuck or has completed all loading tasks.

[0163] Specifically, the stringByEvaluatingJavaScriptFromString function is a system function. Through this function, functions bound to the window by Html can be called. In this step, this function is used to obtain the loading status of the web page.

[0164] Step 52: Determine whether the first loading status is in an active state.

[0165] The function of this step is to determine whether to end the current loading request based on the first loading status.

[0166] Step 53: If the first loading status is not in the active state, then construct the first waitForCompleteJS script.

[0167] The function of this step is to facilitate the execution process of the completeProgress function through the first waitForCompleteJS script.

[0168] Step 54: Determine whether the readyState status of the first waitForCompleteJS script is in a completed state.

[0169] The function of this step is to efficiently obtain the moment when the execution of the completeProgress function starts through the readyState status.

[0170] Step 55: If the readyState status of the first waitForCompleteJS script is in a completed state, then call the completeProgress function to end the current loading request.

[0171] The function of this step is to quickly end the current loading request through the completeProgress function.

[0172] Step 56: Call the incrementProgress function to update the progress displayed in the progress display control to the loaded completed state.

[0173] The function of this step is to promptly display the current process in a visual form to facilitate the user to know the current loading process in real time.

[0174] Here, the present invention also provides a better solution for progress display and update. The specific solution is as follows:

[0175] Step 107 includes:

[0176] Step 61: Call the setProgress function to obtain the current first progress value.

[0177] The function of this step is to accurately know the current loading progress according to the setProgress function.

[0178] Specifically, the first progress value can be determined according to the ratio of the number of completed tasks to the total number of tasks.

[0179] Specifically, the setProgress function is a system function used to initialize and specifically assign values to the progress.

[0180] Step 62: Call the incrementProgress function to obtain the current second progress value.

[0181] The function of this step is to know the progress currently displayed in the display control according to the incrementProgress function.

[0182] Step 63: Determine whether the current first progress value is greater than the current second progress value.

[0183] The function of this step is to determine whether it is necessary to update the progress currently displayed in the display control through this step.

[0184] Step 64: If it is greater, update the current second progress value to the current first progress value.

[0185] The function of this step is to update the current second progress value to facilitate the user to know the current progress in real time.

[0186] Step 65: According to the updated current second progress value, call the incrementProgress function to update the progress displayed in the progress display control.

[0187] The function of this step is to perform a visualization operation according to the current second progress value to facilitate the user to know the current progress in real time.

[0188] When all the load tasks that can be completed in this load task are completed, the webViewDidFinishLoad function will no longer be called. The present invention provides a relatively optimal solution for monitoring the completion progress, specifically:

[0189] After the step 107, the method further includes:

[0190] Step 71, if the webViewDidFinishLoad function is not called, obtain the second loading status of the current page according to the stringByEvaluatingJavaScriptFromString function.

[0191] The function of this step is to determine the loading status of the current page.

[0192] Step 72, determine whether the second loading status is in an active state.

[0193] The function of this step is to determine whether to terminate the request based on the loading status of the current page.

[0194] Step 73, if it is, construct the second waitForCompleteJS script.

[0195] The function of this step is to facilitate the execution process of the completeProgress function through the second waitForCompleteJS script.

[0196] Step 74, determine whether the readyState status of the second waitForCompleteJS script is in a completed state.

[0197] The function of this step is to efficiently obtain the moment when the execution of the completeProgress function starts through the readyState status.

[0198] Step 75, if the readyState status of the second waitForCompleteJS script is in a completed state, call the completeProgress function to end the current loading request.

[0199] The function of this step is to quickly end the current loading request through the completeProgress function.

[0200] Step 76, call the incrementProgress function to update the progress displayed in the progress display control to the loaded completed state.

[0201] The function of this step is to promptly display the current process in a visual form to facilitate the user to know the current loading process in real time.

[0202] To implement the above embodiments, the present invention divides the above steps into 5 parts.

[0203] 1) Preparation work for data interception

[0204] This part needs to define the init function, which includes a pointer maxCount to the maximum number of loading tasks, the number of tasks being loaded loadingcout, and a variable _interactive indicating the current loading state of the task.

[0205] Among them, the number of tasks being loaded loadingcout contains the variable _loadingcout. Through this variable _loadingcout, the pointer maxCount to the maximum number of loading tasks can be assigned a value. When the variable _interactive is YES, it means the task is currently in the loading process; when the variable _interactive is NO, it means the task is not currently in the loading process.

[0206] Here, the pointer maxCount to the maximum number of loading tasks corresponds to the number of current loading tasks that need to be executed in this loading request.

[0207] Define the startProgress function to activate the data loading.

[0208] Define the setProgress function to set the current progress.

[0209] 2) Interception of event tasks before loading data

[0210] To accurately know the loading progress, relevant data before loading the data needs to be obtained, and events are intercepted before the request starts. There is a function shouldStartLoadWithRequest before the web page starts to make a request. This function has multiple function parameters, and one of the function parameters is request. This function is a method that will be called when the page is about to start making a request.

[0211] Through this part, the event tasks before starting to load data can be obtained, so as to know what happened before a request and facilitate updating the progress.

[0212] 3) Interception of the time before loading data

[0213] After the time of this loading request starts, the webViewDidStartLoad function will be called. This function is a function that will be called after the network request starts. This function has one parameter, which is webView. After this function is called, the current function is first called out using the webViewDidStartLoad function.

[0214] This part listens for requests before the time has started, intercepts events before the time request, and updates some progress before the event starts.

[0215] 4) Processing of the event task for completing data loading

[0216] After the network loading is successful, the webViewDidFinishLoad method will be called. After this method is called, this method needs to be delegated, and some event processing needs to be done in this method. This part intercepts when the loading is completed, and at the same time listens to the status in real time through js to ensure that the monitored progress is relatively real-time.

[0217] 5) Processing of the event task for data loading failure

[0218] Through this part, it is possible to monitor the status in real time when the data loading fails, ensuring that more event tasks can be monitored in real time. Finally, through multiple processes and links, it is ensured that the detected process is relatively accurate.
