Description

Technical Field

[0001] The present invention relates to the technical field of computer communication, and in particular to an optimization method and system for multiple devices to access a browser. Background Art

[0002] In the prior art, everyone is very familiar with online shopping. Shoppers have all had the experience of opening a browser to log in to JD.com or Tmall to shop. When you have logged in to jd.com with account A, when your relative logs in with your account A on another device, the account logged in on your device will be forced to go offline.

[0003] But obviously, for some user scenarios, the feature of conventional browsers that "the same account is only allowed to be logged in on one device" cannot meet user needs.

[0004] Currently, a person often has multiple devices and needs to log in to a website at the same time. However, for some websites, after logging in to one device, the other devices will be logged out. At the same time, when multiple devices visit a website, resources need to be downloaded repeatedly, wasting traffic and bandwidth. Summary of the invention

[0005] In order to overcome the above problems, the purpose of the present invention is to provide an optimization method for multiple devices to access browsers, which can realize collaborative login operations across device browsers.

[0006] The present invention is implemented by the following scheme: an optimization method for multiple devices accessing a browser, the optimization method comprising the following steps:

[0007] Step S1, device A initiates a login request to a proxy server through a browser;

[0008] Step S2: The proxy server clears the cookie field in the request header and the content in the cookie field, and sends the request to the target server;

[0009] Step S3: The target server returns the response result to the proxy server;

[0010] Step S4, save the cookie content of the response result in the proxy server, and save the response result content A and the sha1 value corresponding to the response result content A in the proxy server;

[0011] Step S5: The proxy server returns the response result content A and the sha1 value corresponding to the response result content A to device A, and device A saves the content.

[0012] Step S6: Device A initiates a request to the proxy server again, and the proxy server sends the request to the target server. The target server returns the response result to the proxy server. The proxy server generates the difference between the response content and the previously saved response result content A through the delta algorithm, and combines the difference content with the response result content A corresponding to the sha1 value to restore the original response and return it to device A.

[0013] Step S7: If another device B wants to access a website with the same domain name, then since the cookie content of the website already exists in the proxy server, the cookie is directly used to initiate a request to the target server, and the proxy server returns a response to device B, thereby optimizing the browser's access.

[0014] Furthermore, the step S1 is further specified as follows: replacing the target address of the website that the device A originally wants to access with the target address+.proxy.com; and initiating a login request to the proxy server by inputting the URL of the target address+.proxy.com into the browser.

[0015] Furthermore, the step S2 is further specified as follows: the proxy server clears the cookie field in the request header and the content in the cookie field, restores the URL back to the original domain name, and then sends the request to the target server.

[0016] Further, the proxy server generates the difference between the response content and the previously saved response result content A through the delta algorithm, and combines the difference with the response result content A corresponding to the sha1 value to restore the original response and return it to device A. The specific implementation method is as follows: Step S61. The first response of device A is saved as the response result content A and the sha1 value 1 corresponding to the response result content A, and saved in the form of a key-value pair, so that the response result content A can be quickly found through the sha1 value 1 later;

[0017] Step S62. Device A initiates a request again, which is the second response. The second response result is response content 2 and sha1 value 2 corresponding to response content 2;

[0018] Step S63. The second response content 2 is split by the delta algorithm, and the response content 2 is split into the response result content A + the difference content 1, wherein the delta algorithm compares the current response result content A with the content of the response content 2, and generates the operation mode of adding, replacing, and deleting the corresponding content in sequence, and then according to this operation mode, the response content 2 can be restored by the response result content A + the difference content 1;

[0019] Step S64. Since both the proxy server and device A have saved the sha1 value 1 and the response result content A, the proxy server does not need to send the complete response result content A to device A. It only needs to send the sha1 value 1 + the differential content 1 to device A;

[0020] Step S65. Device A locates the previously saved corresponding response result content A through the sha1 value 1, modifies the response result content A according to the operation method of the differential content data, and restores the response content 2.

[0021] Further, step S7 is further specifically as follows: If another device B wants to access the same domain name website through a browser, it first sends a request to the proxy server; the proxy server queries the cookie content of the website that already exists in the request and automatically sends a request to the target server using the cookie content; the target server returns the response to the proxy server, and the proxy server returns the response to device B, thereby optimizing the browser access.

[0022] The present invention also provides an optimization system for multiple devices to access a browser. The optimization system includes: a request sending module, a request header content clearing module, a target server processing module, a storage module, a result feedback module, a differential content merging module, and an access response module;

[0023] The request sending module uses device A to send a login request to a proxy server through a browser;

[0024] The request header content clearing module uses the proxy server to clear the cookie field and the content in the cookie field in the request header and sends the request to the target server;

[0025] The target server processing module uses the target server to return the response result to the proxy server;

[0026] The storage module saves the cookie content of the response result in the proxy server and saves the response result content A and the corresponding sha1 value of the response result content A in the proxy server;

[0027] The result feedback module uses the proxy server to return the response result content A and the corresponding sha1 value of the response result content A to device A, and device A saves them;

[0028] The difference content merging module, when device A initiates a request to the proxy server again, the proxy server sends the request to the target server, the target server returns the response result to the proxy server, the proxy server generates the difference content between the response content and the previously saved response result content A through the delta algorithm, merges the difference content and the response result content A corresponding to the sha1 value to restore the original response and returns it to device A;

[0029] The access response module, when another device B wants to access the website with the same domain name, since the cookie content of the website already exists in the proxy server, directly uses the cookie to initiate a request to the target server, and the proxy server returns the response to device B, thereby optimizing the browser access.

[0030] Furthermore, the implementation of the request sending module is further specifically as follows: replacing the target address of the website that device A originally wants to access with the target address+.proxy.com; and initiating a login request to the proxy server by inputting the URL of the target address+.proxy.com into the browser.

[0031] Furthermore, the implementation method of the request header content clearing module is further specifically as follows: the proxy server clears the cookie field in the request header and the content in the cookie field, restores the URL back to the original domain name, and then sends the request to the target server.

[0032] Further, the proxy server generates the difference between the response content and the previously saved response result content A through the delta algorithm, and combines the difference with the response result content A corresponding to the sha1 value to restore the original response and return it to device A. The specific implementation method is: the first response of device A is saved as the response result content A and the sha1 value 1 corresponding to the response result content A, and saved in the form of a key-value pair, so that the response result content A can be quickly found through the sha1 value 1 later;

[0033] Device A initiates a request again, which is the second response. The second response result is response content 2 and sha1 value 2 corresponding to response content 2.

[0034] The second response content 2 is split by the delta algorithm, and the response content 2 is split into the response result content A + the difference content 1. The delta algorithm compares the current response result content A with the content of the response content 2, and generates the operation mode of adding, replacing, and deleting the corresponding content in sequence. Then, according to this operation mode, the response content 2 can be restored by the response result content A + the difference content 1.

[0035] Since both the proxy server and Device A have saved the sha1 value 1 and the response result content A, the proxy server does not need to send the complete response result content A to Device A. It only needs to send the sha1 value 1 + the differential content 1 to Device A.

[0036] Device A locates the previously saved corresponding response result content A through the sha1 value 1, modifies the response result content A according to the operation method of the differential content data, and restores the response content 2.

[0037] Further, the implementation method of the access response module is further specifically as follows: When another device B accesses the same domain name website through a browser, it first sends a request to the proxy server; the proxy server queries the cookie content of the website that already exists in the request, and automatically uses the cookie content to send a request to the target server; the target server returns the response to the proxy server, and the proxy server returns the response to device B, thereby optimizing the access of the browser.

[0038] The beneficial effects of the present invention are as follows: 1. It realizes cross-device browser collaboration and enables the same account to be logged in through different devices; 2. Adopting the update method of differential content saves the traffic consumed by the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 2 It is a schematic diagram of the system framework principle of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0041] The present invention will be further described below with reference to the accompanying drawings.

[0042] Please refer to Figure 1 As shown, an optimization method for multiple devices to access a browser according to the present invention includes the following steps:

[0043] Step S1: Device A sends a login request to a proxy server through a browser; the step S1 is further specifically as follows: Replace the original website target address that Device A is going to access with the target address +.proxy.com; input this url of the target address +.proxy.com into the browser to send a login request to the proxy server.

[0044] Step S2: The proxy server clears the cookie field and the content in the cookie field in the request header, and sends the request to the target server; the step S2 is further specifically as follows: The proxy server clears the cookie field and the content in the cookie field in the request header, restores the url to the original domain name, and then sends the request to the target server.

[0045] Step S3: The target server returns the response result to the proxy server;

[0046] Step S4, save the cookie content of the response result in the proxy server, and save the response result content A and the sha1 value corresponding to the response result content A in the proxy server;

[0047] Step S5: The proxy server returns the response result content A and the sha1 value corresponding to the response result content A to device A, and device A saves the content.

[0048] Step S6, when device A initiates a request to the proxy server again, the proxy server sends the request to the target server, and the target server returns the response result to the proxy server. The proxy server generates the difference between the response content and the previously saved response result content A through the delta algorithm, and merges the difference content with the response result content A corresponding to the sha1 value to restore the original response and return it to device A; the sha1 value is a hash value used to uniquely mark the response content, which can avoid transmitting the original content during transmission and reduce the transmission traffic.

[0049] Step S7: If another device B wants to access a website with the same domain name, then since the cookie content of the website already exists in the proxy server, the cookie is directly used to initiate a request to the target server, and the proxy server returns a response to device B, thereby optimizing the browser's access.

[0050] The present invention will be further described below in conjunction with a specific embodiment:

[0051] An optimization method for multiple devices to access a browser, requiring device A, device B, and a proxy server;

[0052] 1. Device A initiates a login request to the proxy server through a browser;

[0053] 1.1 The target address that device A originally wanted to access was http: / / www.xxx.com, and now the address to be accessed is replaced with http: / / www.xxx.com.proxy.com; since the present invention uses a proxy server, it is necessary to use the replaced website URL to access the proxy server;

[0054] 2. The proxy server clears the cookie field in the request header and sends the request to the target server;

[0055] 2.1 The proxy server clears the cookie, restores the URL back to the original domain name http: / / www.xxx.com, and sends the request to the target server; that is, clears the cookie field in the request header and the content in the cookie field;

[0056] 3. The target server responds to the proxy server and replaces the domain name.

[0057] 3.1 Replace the matched http: / / www.xxx.com / with http: / / www.xxx.com.proxy.com / ; it may contain image links, script links or other links, then http: / / www.xxx.com / 1.jpg will eventually be replaced with http: / / www.xxx.com.proxy.com / 1.jpg

[0058] 4. The proxy server saves the cookie content of the response result in the proxy server, and saves the response content A and its sha1 value in the proxy server; for example, if the response is the html of a page, it is the sha1 value of this page.

[0059] 5. The proxy server returns the response to device A, which saves the response result A and sha1 value;

[0060] 6. The proxy server generates the difference between the response content and the previously saved response result content A through the delta algorithm, and combines the difference with the response result content A corresponding to the sha1 value to restore the original response and return it to device A. The specific implementation method is as follows: Step S61. The first response of device A is saved as the response result content A and the sha1 value 1 corresponding to the response result content A, and saved in the form of a key-value pair, so that the response result content A can be quickly found through the sha1 value 1 later;

[0061] Step S62. Device A initiates a request again, which is the second response. The second response result is response content 2 and sha1 value 2 corresponding to response content 2;

[0062] Step S63. The second response content 2 is split by the delta algorithm, and the response content 2 is split into the response result content A + the difference content 1, wherein the delta algorithm compares the current response result content A with the content of the response content 2, and generates the operation mode of adding, replacing, and deleting the corresponding content in sequence, and then according to this operation mode, the response content 2 can be restored by the response result content A + the difference content 1; wherein, the delta algorithm is already the existing technology and will not be described in detail again.

[0063] Step S64. Since both the proxy server and device A have saved sha1 value 1 and response result content A, the proxy server does not need to send the complete response result content A to device A, but only needs to send sha1 value 1 + difference content 1 to device A;

[0064] Step S65. Device A searches for the previously saved corresponding response result content A through sha1 value 1, modifies the response result content A according to the operation method of the difference content data, and restores the response content 2.

[0065] That is, device A initiates a request to the proxy server again, and the proxy server sends the request to the target server. The target server responds to the proxy server, and the proxy server generates the difference between the response content and the previously saved response content A through the delta algorithm, and combines the difference content with the response result content A corresponding to the sha1 value to restore the original response. For example: by defining the start position and the end position, the original request is ABCDABCDABE, and the new request is ABCDEABCDXXX; then the delta algorithm generates an incremental package: INSERT position 4, E; REPLACE position 9-10, XXX; in this way, the new request content can be restored through the incremental package and the original operation and value.

[0066] 7. Another device B wants to access the same domain name website through a browser, and first initiates a request to the proxy server;

[0067] 8. The proxy server queries the request for the website's cookie content, and automatically uses the cookie content to initiate a request to the target server; normally, the target server's website will identify a user based on the cookie. This solution places the cookie on the proxy server, making the target server think there is only one user, but actually allowing multiple devices to share the user's permissions; this allows the same account to be logged in through different devices.

[0068] 9. The target server returns the response to the proxy server, and the proxy server returns the response to device B, thereby optimizing the browser's access.

[0069] See also Figure 2 As shown, the present invention also provides an optimization system for multiple devices to access a browser, the optimization system comprising: a request sending module, a request header content clearing module, a target server processing module, a storage module, a result feedback module, a difference content merging module, and an access response module;

[0070] The request sending module uses device A to initiate a login request to a proxy server through a browser;

[0071] The request header content clearing module uses a proxy server to clear the cookie field and the content in the cookie field in the request header and send the request to the target server;

[0072] The target server processing module returns the target server response result to the proxy server;

[0073] The storage module stores the cookie content of the response result in the proxy server, and stores the response result content A and the sha1 value corresponding to the response result content A in the proxy server;

[0074] The result feedback module uses a proxy server to return the response result content A and the sha1 value corresponding to the response result content A to device A, and device A saves the response result content A.

[0075] The difference content merging module, when device A initiates a request to the proxy server again, the proxy server sends the request to the target server, the target server returns the response result to the proxy server, the proxy server generates the difference content between the response content and the previously saved response result content A through the delta algorithm, merges the difference content and the response result content A corresponding to the sha1 value to restore the original response and returns it to device A;

[0076] The access response module, when another device B wants to access the website with the same domain name, since the cookie content of the website already exists in the proxy server, directly uses the cookie to initiate a request to the target server, and the proxy server returns the response to device B, thereby optimizing the browser access.

[0077] The implementation method of the request sending module is further specifically as follows: replacing the target address of the website that device A originally wants to visit with the target address+.proxy.com; and initiating a login request to the proxy server by inputting the URL of the target address+.proxy.com into the browser.

[0078] The implementation method of the request header content clearing module is further specifically as follows: the proxy server clears the cookie field in the request header and the content in the cookie field, restores the URL back to the original domain name, and then sends the request to the target server.

[0079] The proxy server generates the difference between the response content and the previously saved response result content A through the delta algorithm, and combines the difference with the response result content A corresponding to the sha1 value to restore the original response and return it to device A. The specific implementation method is as follows: Step S61. The first response of device A is saved as the response result content A and the sha1 value 1 corresponding to the response result content A, and saved in the form of a key-value pair, so that the response result content A can be quickly found through the sha1 value 1 later;

[0080] Step S62. Device A initiates a request again, which is the second response. The second response result is response content 2 and sha1 value 2 corresponding to response content 2;

[0081] Step S63. The second response content 2 is split by the delta algorithm, and the response content 2 is split into the response result content A + the difference content 1, wherein the delta algorithm compares the current response result content A with the content of the response content 2, and generates the operation mode of adding, replacing, and deleting the corresponding content in sequence, and then according to this operation mode, the response content 2 can be restored by the response result content A + the difference content 1;

[0082] Step S64. Since both the proxy server and device A have saved sha1 value 1 and response result content A, the proxy server does not need to send the complete response result content A to device A, but only needs to send sha1 value 1 + difference content 1 to device A;

[0083] Step S65. Device A searches for the previously saved corresponding response result content A through sha1 value 1, modifies the response result content A according to the operation method of the difference content data, and restores the response content 2.

[0084] The implementation method of the access response module is further specified as follows: when another device B wants to access a website with the same domain name through a browser, it first initiates a request to the proxy server; the proxy server queries the cookie content of the website that already exists in the request, and automatically uses the cookie content to initiate a request to the target server; the target server returns a response to the proxy server, and the proxy server returns a response to device B, thereby optimizing the browser's access.

[0085] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
