[0034] The embodiments of the present disclosure provide a positioning method and system that can convert the abnormal positioning of the compressed and obfuscated JS text into the abnormal positioning of the JS text before compression and obfuscation through the JS mapping file. The method includes obtaining a first JS text and a second JS text, wherein the first JS text is a JS text obtained by packaging the second JS text and having an abnormality; obtaining the row value and column value of the first abnormal information in the first JS text; and determining the second abnormal information corresponding to the first abnormal information in the second JS text according to the row value and column value, and the mapping relationship between the first JS text and the second JS text, and locating the row value and column value of the second abnormal information in the second JS text.

[0035] Figure 1 The exemplary system architecture to which the positioning method and system of the present disclosure can be applied is schematically shown. It should be noted that: Figure 1 What is shown is merely an example of a system architecture to which the embodiments of the present disclosure can be applied, in order to help those skilled in the art understand the technical content of the present disclosure, but it does not mean that the embodiments of the present disclosure cannot be used in other devices, systems, environments or scenarios.

[0036] like Figure 1 As shown, the system architecture 100 according to this embodiment may include terminal devices 101, 102, 103, a network 104 and a server 105. The network 104 is used to provide a medium for communication links between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired and / or wireless communication links, etc.

[0037] Users can use terminal devices 101, 102, 103 to interact with server 105 through network 104 to receive or send messages, etc. Various communication client applications can be installed on terminal devices 101, 102, 103, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients and / or social platform software, etc. (only as examples).

[0038] The terminal devices 101 , 102 , and 103 may be various electronic devices having a display screen and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, and desktop computers.

[0039] The server 105 may be a server that provides various services, such as a background management server (only an example) that provides support for websites browsed by users using the terminal devices 101, 102, and 103. The background management server may analyze and process the received data such as user requests, and feed back the processing results (such as web pages, information, or data obtained or generated according to user requests) to the terminal device.

[0040] It should be noted that the positioning method provided in the embodiment of the present disclosure can generally be executed by the server 105. Accordingly, the positioning system provided in the embodiment of the present disclosure can generally be set in the server 105. The positioning method provided in the embodiment of the present disclosure can also be performed by a server or server cluster that is different from the server 105 and can communicate with the terminal device 101, 102, 103 and / or the server 105.

Accordingly, the positioning system provided in the embodiment of the present disclosure can also be set in the terminal device 101, 102, or 103, or it can be set in other terminal devices different from the terminal device 101, 102, or 103.

[0041] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0042] An APP usually contains many separate businesses, each of which can be developed and packaged using JS scripts in the React Native framework. When the React Native framework packages JS text, it is generally compressed and obfuscated. Therefore, when the JS text runs abnormally, what is actually transmitted to the abnormality location system is the compressed and obfuscated JS text. In this case, if the uploaded JS text is directly used for abnormal location, it is difficult to locate the problem on the one hand, and even if the problem is located, it is difficult for the staff to understand what the abnormality is.

[0043] By using the technical solution provided by the present invention, the abnormal problems appearing in the JS text after packaging can be mapped to the JS text before packaging according to the mapping relationship between the two JS texts before and after packaging, which can not only facilitate positioning, but also facilitate the staff to understand the abnormal problems.

[0044] Figure 2 The flowchart of the positioning method according to the embodiment of the present disclosure is schematically shown.

[0045] like Figure 2 As shown, the method includes operations S210 to S230, wherein:

[0046] In operation S210, a first JS text and a second JS text are acquired, wherein the first JS text is an abnormal JS text obtained by packaging the second JS text.

[0047] In other words, the first JS text is relatively the JS text after packaging, and the second JS text is the JS text before packaging, and both texts have exceptions when running.

[0048] Specifically, if an exception occurs during the operation of the first JS text, the React Native service will report it to the exception reporting system. Therefore, the first JS text can be obtained from the exception reporting system.

[0049] In operation S220 , a row value and a column value of first abnormal information in the first JS text are acquired.

[0050] Specifically, the source-map tool can be used to parse the packaged JS exception text, find out the error code, and locate the position of the error code, that is, read the row position and column position of the error code in the packaged JS exception text.

[0051] In operation S230, second exception information corresponding to the first exception information in the second JS text is determined according to the row value and the column value, and the mapping relationship between the first JS text and the second JS text, and the row value and the column value of the second exception information in the second JS text are located.

[0052] Specifically, according to the mapping relationship between the two JS texts before and after packaging, the row value and column value corresponding to the error code in the packaged JS exception text can be respectively mapped to the JS exception text before packaging, so as to obtain the row value and column value corresponding to the error code in the JS exception text before packaging, and use the content on the row and column corresponding to the row value and column value as the error code in the JS exception text before packaging.

[0053] Compared with the prior art that directly locates the (compressed / obfuscated) JS exception text after packaging, which makes it difficult to locate the problem, and even if the problem is located, it is difficult to understand the exception problem based on the compressed and obfuscated code, the embodiments of the present disclosure can locate the JS exception text before packaging, which is not only easy to locate the problem, but also easy to understand the exception problem based on the code that has not been compressed and obfuscated.

[0054] Reference below Figure 3-4 as well as Figure 5A to Figure 5B , combined with specific embodiments Figure 2 The method shown is further explained.

[0055] As an optional embodiment, the method further includes: obtaining a mapping file generated when packaging the second JS text; and obtaining a mapping relationship between the first JS text and the second JS text based on the mapping file.

[0056] like Figure 3 As shown, JS text 1 is a code developed using React Native. After packaging, it will generate compressed and obfuscated JS text 2. At the same time, it will also generate a mapping file that can describe the mapping relationship between JS text 1 and JS text 2.

[0057] Based on this, the mapping relationship between the first JS text and the second JS text can be obtained through the mapping file. Specifically, the mapping files (i.e., .map files) and the values ​​of line and column can be passed to the Source map for parsing, and the output result will locate the specific error point. For example:

[0058]

[0059] Based on this result, we can quickly find the location of the JS exception text error, that is, the location of "line: 261, column: 24", and determine the error code, that is, "scrollTo". In this way, we can convert all the exception information, and business personnel can also quickly locate the problem based on the provided exception information when querying the exception information.

[0060] According to the embodiment of the present disclosure, since the JS application implemented based on React Native will generate a mapping file of the pre-packaging file and the post-packaging file at the same time when packaging, the mapping relationship between the two JS texts can be found through this file.

[0061] As an optional embodiment, the first JS text is parsed according to the row value and column value, and the mapping relationship between the first JS text and the second JS text to determine the second exception information corresponding to the first exception information in the second JS text, and locate the row value and column value of the second exception information in the second JS text.

[0062] like Figure 4As shown, JS text 1 is a code developed using React Native. After packaging, it will generate a compressed and obfuscated JS text 2. Parsing JS text 1 found that the error code is "xxx", which is located at the mth line and nth column in JS text 1. According to the mapping relationship between JS text 1 and JS text 2, it is found that the 261st line in JS text 2 corresponds to the mth line in JS text 1, and the 24th column in JS text 2 corresponds to the nth column in JS text 1. In addition, the code at the 261st line and 24th column in JS text 2 is "scrollTo". Therefore, the error code in JS text 2 is finally located as "scrollTo", and "scrollTo" is located at the 261st line and 24th column in JS text 2.

[0063] As an optional embodiment, the method also includes: before parsing the first JS text, determining the packaging method of the first JS text; parsing the first JS text, including: parsing the first JS text according to the packaging method of the first JS text.

[0064] As mentioned above, an APP usually contains many separate businesses, each of which can be developed and packaged using JS scripts in the React Native framework.

[0065] In one case, for each business, we can package it into a full package, which will result in a lot of duplicate files in the APP, greatly increasing the size of the code, especially when there are many React Native applications in the APP, this phenomenon is more obvious.

[0066] like Figure 5A As shown, after the packaging process, the JS text 1 can be packaged into a JS text 2 in a "full package" form.

[0067] In another case, for each business, we can also use some public dependency packages (that is, all businesses will use dependencies into a public package), such as reactnative, react, or a set of component libraries encapsulated within the company, etc., and package them into "split package + dependency package", which can greatly reduce the size of the code.

[0068] like Figure 5B As shown, after packaging, JS text 1 can be packaged into a split package and a dependent package, that is, JS text 2 includes a split package and a dependent package.

[0069] It should be noted that, usually, we integrate all the follow-up services (i.e. services released with the APP version) in the form of "split package + dependent package". However, if it is an online upgrade service, we generally use the "full package" method for integration.

[0070] Since the mapping files of the two JS texts describe the mapping relationship between all the codes of the two texts, only the text in the form of a full package can be parsed directly, and the text in the form of a split package + dependent package cannot be parsed directly. Therefore, in the present disclosed embodiment, the packaging method needs to be considered when parsing the JS text.

[0071] As an optional embodiment, the first JS text is parsed according to the packaging method of the first JS text, including: when the first JS text is in the form of a full package, directly parsing the full package of the first JS text; and when the first JS text is in the form of a split package plus a dependent package, first synthesizing the split package and the dependent package of the first JS text into a full package, and then parsing the synthesized full package.

[0072] like Figure 4 As shown in the figure, JS text 1 is a fully-packed text, so it can be parsed directly. For text that is not fully-packed, since it cannot be parsed directly, you can consider merging its split packages and dependent packages into a fully-packed package, and then follow the steps below. Figure 4 The merged text is parsed in the manner shown.

[0073] Specifically, during the parsing process, you can first determine whether the JS exception text is a full package. If so, get the .map file of this full package for parsing. If not, first merge the split package and dependent package of the JS exception text, and then use its .map file for parsing.

[0074] Since the mapping file of the two JS texts describes the mapping relationship between all the codes of the two texts, only the text in the form of a full package can be parsed directly, and the text in the form of a split package + a dependent package cannot be parsed directly. Therefore, in the present disclosed embodiment, by merging the split package + the dependent package, the JS text in the non-full package form can also be parsed based on the mapping file.

[0075] As an optional embodiment, the split packages and dependent packages of the first JS text are combined into a full package, including: obtaining the split packages and dependent packages of the first JS text; obtaining the length value of the sections field of the dependent package; traversing the sections field of the split packages, resetting the corresponding original line value to the corresponding new line value, wherein the corresponding new line value is equal to the corresponding original line value plus the length value of the sections field of the dependent package; and after traversal and resetting, appending the sections field of the split package to the sections field of the dependent package, thereby combining the split packages and dependent packages of the first JS text into a full package.

[0076] Since appending the sections field of the split package to the sections field of the dependent package will not change the column position of the relevant code in the split package, but will change its row position, in the merging logic of the split package and the dependent package, there is no need to reset the column value of each code in the split package, and only the row value needs to be changed. Specifically, the row value of each code in the split package can be uniformly added to the length value of the sections field of the dependent package.

[0077] As an optional embodiment, obtaining the row value and column value of the first exception information in the first JS text includes: parsing the first JS text through a pre-written JS script to determine the first exception information, and locating the row value and column value of the first exception information in the first JS text.

[0078] Specifically, a node script can be pre-written, which can parse the JS exception text reported by the React Native business, determine the error code therein, and read the row position (ie, row value) and column position (ie, column value) of the error code in the JS exception text.

[0079] Figure 6 A block diagram of a positioning system according to an embodiment of the present disclosure is schematically shown.

[0080] like Figure 6 As shown, the positioning system 600 includes a first acquisition module 610 , a second acquisition module 620 and a positioning module 630 .

[0081] A first acquisition module 610 is used to acquire a first JS text and a second JS text, wherein the first JS text is a JS text obtained by packaging the second JS text and contains an abnormality;

[0082] A second acquisition module 620 is used to acquire a row value and a column value of the first abnormal information in the first JS text; and

[0083] The positioning module 630 is used to determine the second exception information corresponding to the first exception information in the second JS text according to the row value and column value, and the mapping relationship between the first JS text and the second JS text, and locate the row value and column value of the second exception information in the second JS text.

[0084] Compared with the prior art that directly locates the (compressed / obfuscated) JS exception text after packaging, which makes it difficult to locate the problem, and even if the problem is located, it is difficult to understand the exception problem based on the compressed and obfuscated code, the embodiments of the present disclosure can locate the JS exception text before packaging, which is not only easy to locate the problem, but also easy to understand the exception problem based on the code that has not been compressed and obfuscated.

[0085] As an optional embodiment, the system also includes: a third acquisition module, used to acquire a mapping file generated when packaging the second JS text; and a fourth acquisition module, used to acquire a mapping relationship between the first JS text and the second JS text based on the mapping file.

[0086] According to the embodiment of the present disclosure, since the JS application implemented based on React Native will generate a mapping file of the pre-packaging file and the post-packaging file at the same time when packaging, the mapping relationship between the two JS texts can be found through this file.

[0087] As an optional embodiment, the positioning module is also used to: parse the first JS text according to the row value and column value, and the mapping relationship between the first JS text and the second JS text, so as to determine the second exception information corresponding to the first exception information in the second JS text, and locate the row value and column value of the second exception information in the second JS text.

[0088] As an optional embodiment, the system also includes: a determination module, which is used to determine the packaging method of the first JS text before parsing the first JS text; the positioning module is also used to: parse the first JS text according to the packaging method of the first JS text.

[0089] Since the mapping files of the two JS texts describe the mapping relationship between all the codes of the two texts, only the text in the form of a full package can be parsed directly, and the text in the form of a split package + dependent package cannot be parsed directly. Therefore, in the present disclosed embodiment, the packaging method needs to be considered when parsing the JS text.

[0090] As an optional embodiment, the positioning module includes: a first parsing unit, which is used to directly parse the whole package of the first JS text when the first JS text is in the form of a full package; and a second parsing unit, which is used to first synthesize the split package and the dependent package of the first JS text into a full package when the first JS text is in the form of a split package plus a dependent package, and then parse the synthesized full package. Since the mapping files of the two JS texts describe the mapping relationship between all the codes of the two texts, only the text in the form of a full package can be directly parsed, and the text in the form of a split package + a dependent package cannot be directly parsed. Therefore, in the disclosed embodiment, by merging the split package + the dependent package, the JS text in the non-full package form can also be parsed based on the mapping file.

[0091] As an optional embodiment, the second parsing unit is also used to combine the split packages and dependent packages of the first JS text into a full package, and is specifically used to: obtain the split packages and dependent packages of the first JS text; obtain the length value of the sections field of the dependent package; traverse the sections field of the split package, and reset the corresponding original line value to the corresponding new line value, wherein the corresponding new line value is equal to the corresponding original line value plus the length value of the sections field of the dependent package; and after traversal and resetting, append the sections field of the split package to the sections field of the dependent package, thereby combining the split packages and dependent packages of the first JS text into a full package.

[0092] As an optional embodiment, the second acquisition module is further used to: parse the first JS text through a pre-written JS script to determine the first exception information, and locate the row value and column value of the first exception information in the first JS text.

[0093] According to the modules and units of the embodiments of the present disclosure, any multiple or at least part of the functions of any multiple thereof can be implemented in one module. According to the modules and units of the embodiments of the present disclosure, any one or more can be split into multiple modules for implementation.
