Instructs the browser to load a script packaged in the extension, known as the API script, this script is used to export a set of custom API methods for use in user scripts. The API script path, relative to the manifest.json file, is defined as a
string
in
"api_script"
.
注意：
user_script
key is required for the
userScripts
API to function, even if no API script is specified. For example.
user_scripts: {}
.
The API script:
The script executes automatically on any webpage defined in
匹配
by
userScripts.register
. However, this is before the user script sandbox object is created and the custom API methods can be exported.
To export the custom API methods, the script listens for
userScripts.onBeforeScript
and then export the custom API methods.
Not every user script may need to consume all of the custom API methods. You can, therefore, include details of the APIs needed in
scriptMetadata
when running
userScripts.register
. The API script then accesses the
scriptMetadata
透过
script
parameter received by the
userScripts.onBeforeScript
listener (as
script.metadata
).
