The embodiment corresponds to an application scenario in which an application program is downloaded through a client, and source information corresponding to an application program downloading instruction does not include privacy information; further, in one embodiment, the source to which the application download instruction corresponds is the client, which includes the source being the client-side embedded web page (the user downloads the application through the client-side embedded web page) and the source being the client itself (i.e., the user downloads the application through the client).
In one embodiment, for example, an application program is downloaded through a client, in this embodiment, after an application program download instruction is received, source information is obtained, whether the source information is privacy information is detected when a source corresponding to the download instruction is determined to be the client, a corresponding uniform resource locator is obtained when the source information is determined to include non-privacy information, the source information is spliced to the uniform resource locator by the client of the terminal, an updated uniform resource locator is obtained, and the updated uniform resource locator is sent to the download server.
In one embodiment, for example, downloading the application program through the client-side embedded web page, in this embodiment, after receiving the application program downloading instruction, source information is obtained, whether the source information is privacy information is detected when it is determined that a source corresponding to the downloading instruction is the client-side embedded web page, when it is determined that the source information includes non-privacy information, the client-side splices the source information (a source of the client-side embedded web page) to the uniform resource locator, obtains an updated uniform resource locator, and sends the updated uniform resource locator to the downloading server. When the application program is downloaded through the embedded webpage of the client and the application program is downloaded through the client, and the source information does not include privacy information, the updated uniform resource locator is sent to the download server by the client. In one embodiment of downloading the application via the client side embedded web page, the source information includes client side embedded web page information and client side information.
In another embodiment, after obtaining the source information corresponding to the application program downloading instruction, the method further detects the source information, please continue referring to fig. 3, and when determining that the source of the application program downloading instruction is the client page according to the source information and the source information includes the privacy information, sends the uniform resource locator corresponding to the application program downloading instruction to the download server; in the embodiment, an application program installation package returned by a download server according to a uniform resource locator is received; and writing the source information into a preset position of the application program installation package.
In this embodiment, the application program is downloaded through the client, and the source information corresponding to the application program downloading instruction includes an application scenario of private information. In this embodiment, after receiving the application program download instruction, the terminal acquires the corresponding uniform resource locator and directly sends the uniform resource locator to the download server. After the terminal receives the application program installation package, the client of the terminal writes the source information into the preset position of the application program installation package to obtain the updated application program installation package. Therefore, when the updated application program installation package is started, the terminal can also read the source information corresponding to the application program installation package, and the purpose of transmitting information to the application program is achieved.
In one embodiment, the predetermined location for writing the source information into the application installation package may be a signature area of the application installation package. In a specific embodiment, the signature of the Android (Android) application installation package is divided into two signature modes of a V1 signature and a V2 signature, and according to different system versions of the terminal, different signature modes are adopted for writing source information into the application installation package. It should be understood that, in the present embodiment, only two current signature manners of the android application installation package are exemplified, and the method in the present embodiment may also write the source information into the application installation package by using other signature manners that may occur along with the technology development.
According to the method in the embodiment, when the source information is detected to contain the privacy information, the source information can be prevented from being leaked in the process of splicing the source information to the uniform resource locator and sending the source information to the download server in the future by writing the source information into the application program installation package by the client, and the safety of information transmission to the application program is further improved.
Further, in one embodiment of downloading the application via the client-side embedded web page, the client-side embedded web page of the terminal sends its own information to the client-side if it is detected that the source information includes privacy information. In one embodiment, the source information is sent to the client by the client embedded webpage of the terminal through the JSAPI technology. In other embodiments, the client-side inline web page may also send the source information to the client-side through other techniques.
In one embodiment, determining whether the source information is the private information may be performed in any manner.
Furthermore, in another embodiment in which the source is determined to be a client page according to the source information corresponding to the application download instruction, the source information including non-private information may also be written into the application installation package by the client of the terminal.
Further, in an embodiment where a client of the terminal writes source information into the application program installation package and determines that a source is a client page according to the source information corresponding to the application program download instruction, before writing the source information into a preset position of the application program installation package, the method further includes: acquiring system version information of a terminal; and determining a preset position where the source information to be written into the application installation package according to the system version information.
In this embodiment, in the installation process of an Android (Android) application installation package, a signature performed on the application installation package is verified. At present, an android application installation package is divided into a V1 signature mode and a V2 signature mode, and the adopted signature modes are different according to different system version information of a terminal. Therefore, in the embodiment, the preset position where the source information needs to be written into the application program installation package is determined according to the acquired system version information of the terminal where the source information is located; in a specific embodiment, when the system version is determined to be below android7.0 according to the system version information and does not support the V2 signature, the V1 signature is adopted.
Specifically, the description will be made taking an example of writing source information into an application package using a V1 signature or a V2 signature according to system version information.
The original zip content cannot be modified in embodiments that use the V2 signature to write source information to the application installation package because the implementation of the V2 signature would perform an integrity check on the contents of the entire application installation package. The android application installation package structure comprises a content area, a signature block, an installation package central directory and a central tail, and during verification, the application installation package cannot verify the signature block, so that a source is written into the signature area. The specific future source information is written into the V2 signature area, and the specific position is that the end of the V2 signature block is shifted forward by 24 bytes. The "ID-value" pairs whose IDs are unknown are ignored in verifying the application installation package, so the source information is embedded behind the sequence of "ID-value" pairs in this embodiment; as shown in fig. 4, a schematic diagram of a position where source information is written into an application installation package by using a V2 signature method, where a live extension block shown in the diagram is a position where the source information is written into the application installation package when using a V2 signature method in this embodiment.
In the embodiment that the source information is written into the application program installation package by adopting the V1 signature, the content integrity of the application program installation package cannot be verified by adopting the V1 signature, so that the source information can be directly written into the content area of the application program installation package when the V1 signature is adopted; fig. 5 is a schematic diagram illustrating the writing of source information into the location of the application installation package by using V1 signature. In another embodiment, the V1 signature method is adopted, and the source information may also be written before the central core directory of the installation package, so as to ensure uniform reading and writing of the source information written by different signature methods.
In an embodiment of determining that the source is a client page according to source information corresponding to the application program download instruction, where the source information includes privacy information, the method further includes: and when the application installation package belongs to the preset white list, writing the source information into the preset position of the application installation package.
In this embodiment, the preset white list is an embodiment in which the source information is written through the client (the source is a client page, and the source information includes privacy information), and is used to specify an application program that needs to write the source information in the application program installation package, that is, when the application program is downloaded through the client or the application program is downloaded through an embedded web page of the client, only the source information of the download instruction is written in the application program installation package corresponding to the application program belonging to the preset white list. In one embodiment, whether the application installation package belongs to the preset white list is determined by obtaining version information (such as an application installation package name and version information of the application installation package) corresponding to the application installation package.
In one embodiment, the method further comprises: acquiring a preset information writing protocol associated with an application program; writing the source information into the preset position of the application program installation package comprises the following steps: and writing the source information into the preset position of the application program installation package according to a preset information writing protocol.
Wherein the predetermined information writing protocol specifies a format to which the source information is to be written into the application installation package. In one embodiment, the preset information writing protocol is stored in json format, and each terminal takes a respective Key for writing in the writing process in a Key value mode, so that the terminals are not affected by each other. If the written information needs to be expanded, only the written key and value values need to be expanded, and the expandability is strong. And finally, json data is converted into a binary string and written into the Apk, the processing mode is simple and safe, all parties needing to write data into the Apk can write the data according to a defined protocol format, and if the data are not written according to the format, the original data can be erased and new data can be written.
In a specific embodiment, the specific content of the preset information writing protocol is as follows:
{
"TxVideoInfo": context: "cid & vid & xxx" },// the format of the written information when the source is the client;
h5Info, xxx, source is the format of the written information when the webpage of the embedded webpage of the client side is used;
"CdnInfo": xxx "// format of the written information when the source information is written by the download server;
}
in other embodiments, the predetermined information writing protocol may be set in other forms.
In another embodiment, the present application further provides an application installation package pushing method, which is mainly used for illustration by applying the method to the download server 120 in fig. 1. As shown in fig. 6, the method includes steps S610 to S650.

In this embodiment, after receiving and parsing the url, the download server may detect whether other information, such as source information, is included therein; when the source information is detected to be included, the source information is written into the preset position of the application program installation package, that is, the application program installation package in which the source information is written is obtained, and the application program installation package is recorded as an updated application program installation package in this embodiment.
And step S650, returning the updated application program installation package to the terminal.
According to the method, when the download server receives the uniform resource locator containing the source information, the source information is written into the preset position of the application program installation package, and when the terminal receives the updated application program installation package and starts the updated application program installation package, the source information can be read, so that the purpose of transmitting information to the application program is achieved through the method, meanwhile, the situation that the source information is tampered by other programs is avoided, and the safety of the transmitted source information is improved.
Further, in an embodiment, before writing the source information into the preset location of the application installation package, the method further includes: acquiring system version information of a terminal; and determining a preset position of writing the source information to be written into the application installation package according to the system version information.
In this embodiment, in the installation process of an application installation package of Android (Android), a signature performed on the application installation package is checked. At present, an android application installation package is divided into a V1 signature mode and a V2 signature mode, and the adopted signature modes are different according to different system version information of a terminal. Therefore, in this embodiment, it is determined that the source information needs to be written into the preset position of the application installation package according to the acquired system version information of the terminal where the source information is located.
Specifically, the description will be made taking an example of writing source information into an application package using a V1 signature or a V2 signature according to system version information.
The original zip content cannot be modified in embodiments that use the V2 signature to write source information to the application installation package because the implementation of the V2 signature would perform an integrity check on the contents of the entire application installation package. The android application installation package structure comprises a content area, a signature block, an installation package central directory and a central tail, and during verification, the application installation package cannot verify the signature block, so that a source is written into the signature area. The specific future source information is written into the V2 signature area, and the specific position is that the end of the V2 signature block is shifted forward by 24 bytes. The android terminal ignores the "ID-value" pair with unknown ID when checking the application installation package, so the source information is embedded behind the "ID-value" pair sequence in this embodiment.
In the embodiment of writing the source information into the application program installation package by adopting the V1 signature, the content integrity of the application program installation package cannot be verified by adopting the V1 signature, so that the source information can be directly written into the content area of the application program installation package by adopting the V1 signature. In another embodiment, the V1 signature method is adopted, and the source information may also be written before the central core directory of the installation package, so as to ensure uniform reading and writing of the source information written by different signature methods.
In another embodiment, the method further comprises: acquiring a preset information writing protocol associated with an application program; writing the source information into the preset position of the application program installation package comprises the following steps: and writing the source information into the preset position of the application program installation package according to a preset information writing protocol.
Wherein the predetermined information writing protocol specifies a format to which the source information is to be written into the application installation package. In one embodiment, the preset information writing protocol is stored in json format, and each terminal takes a respective Key for writing in the writing process in a Key value mode, so that the terminals are not affected by each other. If the written information needs to be expanded, only the written key and value values need to be expanded, and the expandability is strong. And finally, json data is converted into a binary string and written into the Apk, the processing mode is simple and safe, all parties needing to write data into the Apk can write the data according to a defined protocol format, and if the data are not written according to the format, the original data can be erased and new data can be written.
In a specific embodiment, as shown in fig. 7, taking an example that a user directly clicks a download application at a client to download a target application in an android source application (corresponding to sending a uniform resource locator to a download server and receiving a corresponding application installation package returned by the download server), after downloading is completed, the client of the terminal writes source information (such as page information, location information, and a user operation path) in the obtained application into the application installation package; the writing mode of the source information is divided into a V1 signature area and a V2 signature area, and the writing mode is different according to different signature modes. And when the writing is successful, popping up the installation panel, and installing the installation panel into a preset directory of the application program. In another embodiment, the source information may also be written into the local hard disk, and the source information may be obtained by reading the content of the local hard disk after the application installation package is installed. In another embodiment, when the user directly clicks the download application program at the client, the client may also splice the source information to the corresponding uniform resource locator and send the source information to the download server, and the download server writes the source information into the corresponding application program installation package and then returns the application program installation package in which the source information is written to the client.
In another embodiment, as shown in fig. 8, for example, a user clicks and downloads an application through an embedded web page in a client, if in an H5 page embedded in an android client, the H5 sends source information to the client through JSAPI technology, and the client encapsulates the H5 information and writes the encapsulated source information and the page information of the client into an application installation package, so that the application installation package can count operation information and source information in the client and the H5 at the same time. In another embodiment, when the user clicks to download the application program through the embedded web page in the client, the embedded web page in the client may also splice the source information to the corresponding uniform resource locator and send the uniform resource locator to the client, the client sends the uniform resource locator spliced with the source information to the download server, and the download server writes the source information into the corresponding application program installation package and then returns the application program installation package written with the source information to the client.
In another embodiment, as shown in fig. 9, for example, when a user downloads an application by clicking on a web page of a browser, channel information, source information, and a user operation path also need to be written into application installation package information when downloading through an H5 page, and an application installation package file cannot be directly operated in H5, so that by encrypting the source information in sha1 and splicing the encrypted source information into a corresponding uniform resource locator, when downloading the application installation package, the encrypted information (hereinafter referred to as cdn information) of the uniform resource locator is decrypted in cdn (a download server) background, and the source information is written into the application installation package by a download server background, so that the terminal can also obtain corresponding source and user information when starting the application installation package.
According to the pushing method of the application program installation package, the program information is transmitted to the application in a lossless mode by using the signature area of the application program installation package, the accuracy of writing the source information of the application program installation package is improved, and a decision maker can conveniently make a correct decision according to data analysis.
