PHP Auto-signature with exec function for apk

developed by the company Android application, because the signature files in different platforms, need to be signed separately, this is very troublesome, so require in the company's back-office management system to upload the APK file, automatically use different platform signature file to complete the signature, This will only need to upload a file to get all the platform signed APK , distribution is much more convenient.

specifically how to APK file to sign, there are many articles on the Internet, please search by yourself. Given the number of commands used throughout the signature process, a script was written to complete the signature so that only the exec () function would be required to execute the script in PHP.

The idea is correct, but after writing the script, PHP Executes the script when there is a problem, the script underWindows is not a problem, theLinux script does not, theexec () output parameter returned to {}, viewing background file discovery also did not generate a signature file.

jar , jarsigner command failed, these commands were not executed at all, searched the internet for half a day , the findings are mostly as follows:

1. permissions are not enough, to improve the permissions of PHP exec () to sudo, and to avoid password;

2. PHP exec () can only perform system-native commands and cannot perform commands for third-party applications installed later;

for Argument 1 , try the following:

      1, set php-fpm.conf user parameter is Span lang= "en-us" xml:lang= "en-US" >root , starting lang= with php-fpm–r "en-US" command Lang= "en-us" xml:lang= "en-US" >php , at this time php-fpm process user is root

2. PHP-FPM The default user is Nginx, adding the user to the sudoers , and is set to password-free;

all of the above methods fail validation.

finally Accidental discovery, originally not a permissions issue, nor exec () Only native commands can be executed, originally path problem , which would have jar , jarsigner command added to System Span lang= "en-us" xml:lang= "en" >path parameter, but do not know why, in exec () The function does not seem to recognize the path parameter, also did not find jar , jarsigner command, which causes the signature to fail , the final script is as follows (the red part of the code is intentionally adding a path to a third-party command):
