F#

Step 1: Prepare the environment

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

1. Install Funcraft on the local 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 call a function

1. Run the following command to clone the sample project to your local device.

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

   Note If you have not installed Git, download it from https://github.com/awesome-fc/fc-custom-demo and install it.
2. Run the following command to access the cloned sample project:

   cd fc-custom-demo
   cd FSharp-demo

3. Run the following command to deploy the function:

   make deploy                       

   The following result is returned:

   docker run -it -v $(pwd):/tmp mcr.microsoft.com/dotnet/core/sdk:3.1 bash -c "cd /tmp/FSharpDemo && dotnet publish -r linux-x64 -c Release --self-contained true && cd /tmp/FSharpDemo/bin/Release/netcoreapp3.1/linux-x64/publish && mv FSharpDemo bootstrap && chmod +x bootstrap"

                   The function fc_fsharp has been packaged. A total of 338 files were compressed and the final size was 39.3 MB
                   Waiting for HTTP trigger http_t to be deployed...
                   triggerName: http_t
                   methods: [ 'GET', 'POST', 'PUT', 'DELETE' ]
                   url: https://19861144305****.cn-hangzhou.fc.aliyuncs.com/2016-08-15/proxy/fsharp_demo/fc_fsharp/
                   Http Trigger will forcefully add a 'Content-Disposition: attachment' field to the response header, which cannot be overwritten 
                   and will cause the response to be downloaded as an attachment in the browser. This issue can be avoided by using CustomDomain.
   
                   trigger http_t deploy success
           function fc_fsharp deploy success
   service fsharp_demo deploy success
   
   Detect 'DomainName:Auto' of custom domain 'my_domain'
   Fun will reuse the temporary domain 16225220-19861144****.test.functioncompute.com, expired at 2020-04-17 10:07:00, limited by 1000 per day.
   
   Waiting for custom domain my_domain to be deployed...
   custom domain my_domain deploy success

4. Run the following command to call the deployed function:

   In this example, directly use curl or the browser to access the temporary domain name 16225220-198611443****.test.functioncompute.com after the function is deployed.

   curl 16225220-1986114430****.test.functioncompute.com/weatherforecast          

   The following result is returned:
