Concepts
Execution method
The execution method specifies the starting file and function while invoking the cloud function as shown below:
For Go programming, use the FileName format, such as
main.For Python, Node.js, or PHP programming, use the FileName.FunctionName format, such as
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" in Basic Concepts.
- 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, such as
example.Hello::mainHandler.For the Custom Runtime environment, a non-fixed format can be used based on the custom programming language implementation.
