Execution method
Execution method specifies which function in which file is executed first when the cloud function is invoked, as shown in the following figure.
- For Golang programming, use the FileName format, for example,
main. - For Python, Node.js, or PHP programming, use the FileName.FunctionName format, for example,
index.main_handler.- Please note that FileName does not include the file name extension, and FunctionName is the name of the entry function. Ensure that the file name extension matches the programming language. For example, for Python programming, the file name extension is
.py; and for Node.js programming, the file name extension is.js. For more information, please see Execution Method.
- Please note that FileName does not include the file name extension, and FunctionName is the name of the entry function. Ensure that the file name extension matches the programming language. For example, for Python programming, the file name extension is
- For Java programming, use the package.class::method format, for example,
example.Hello::mainHandler. - For the Custom Runtime environment, a non-fixed format can be used based on the custom programming language implementation.
