Python

Step 1: Prepare the environment

The easiest way to install Funcraft is to download the executable binary files.

1. Install Funcraft on an on-premises machine. For more information, see Install Funcraft.
2. Run the fun --version command to check whether the installation is successful.
3. Run the fun config command to configure Funcraft. Set the Account ID, Access Key ID, Access Key Secret, and Default region name parameters as prompted.

   fun config
   Aliyun Account ID 1234xxx
   Aliyun Access Key ID xxxx
   Aliyun Access Key Secret xxxx
   Default region name cn-xxxx
   The timeout in seconds for each SDK client invoking 300
   The maximum number of retries for each SDK client 5
   Allow to anonynously report usage statistics to improve the tool over time? (Y/n)

Step 2: Deploy and invoke a function

1. Run the following command to clone the sample project to the on-premises machine:

   git clone https://github.com/awesome-fc/fc-custom-demo          

   Note If you do not install Git, you can download the sample project from https://github.com/awesome-fc/fc-custom-demo.
2. Optional:Modify the sample code in the python37-demo directory to implement your business logic.
3. Run the following commands to go to the cloned sample project:
   1. Run the following command to go to the fc-custom-demo directory:

      cd fc-custom-demo

   2. Run the following command to go to the python37-demo directory:

      cd python37-demo    

4. Run the following command to install dependencies:

   fun install -v   

   The following result is returned:

   copying function artifact to D:\fc-custom-demo\python37-demo
   
   Install Success 

5. Run the following command to deploy the project to Function Compute:

   fun deploy -y      

   The following result is returned:

   Waiting for service python37-demo to be deployed...
           Waiting for function fc-python37 to be deployed...
                   Waiting for packaging function fc-python37 code...
                   The function fc-python37 has been packaged. A total of 2 files were compressed and the final size was 641 B
           function fc-python37 deploy success
   service python37-demo deploy success

6. Run the following command to invoke the deployed function:

   fun invoke -e "Hello World"          

   Note If you use the Windows operating system, you must convert the format of the bootstrap file to UNIX.
   The following result is returned:
