You can migrate F# ASP.NETCore projects by using the Custom Runtime and HTTP triggers
of Function Compute. You can access a function by using a browser or HTTP client tools
such as curl.
Prerequisites
Before you install Funcraft, make sure that you have completed the following steps:
Note
- The examples in this topic apply to scenarios where Docker is installed. If you do
not want to use Docker, you need to install .NET Core 3.1. For more information about
installation, see dot.net.core3.1. For more information about the command, see fc-custom-demo.
- If you have installed Funcraft, go to Step 2: Deploy and call a function.
Step 1: Prepare the environment
The easiest way to install Funcraft is to download the executable binary files.
- Install Funcraft on the local machine. For more information, see Install Funcraft.
- Run the
fun --version
command to check whether the installation is successful.
- 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
- Run the following command to clone the sample project to your local device.
git clone https://github.com/awesome-fc/fc-custom-demo
- Run the following command to access the cloned sample project:
cd fc-custom-demo
cd FSharp-demo
- 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"

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.

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
- 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
