.NET Core - 函数计算

通过函数计算的Custom Container，您可以使用.NET Core在函数计算平台编辑函数。本文介绍如何快速部署和调用.NET Core函数。您也可以按需修改.NET Core的示例代码实现二次开发。

前提条件

您已完成以下操作：

操作步骤

在目标目录中，执行以下命令，初始化项目。

s init start-fc-custom-container-http-aspdotnetcore -d start-cc-http-aspdotnetcore

-d用于指定项目名称，本示例项目名称为start-cc-http-aspdotnetcore。

说明若已存在该项目则跳过此步骤。

输出示例：

 Serverless Awesome: https://github.com/Serverless-Devs/package-awesome

 file decompression completed
 please select credential alias default

 Thanks for using Serverless-Devs
 You could [cd /test/start-cc-http-aspdotnetcore] and enjoy your serverless journey!
 If you need help for this example, you can use [s -h] after you enter folder.
 Document Star：https://github.com/Serverless-Devs/Serverless-Devs

执行以下命令，进入项目目录：
```
cd start-cc-http-aspdotnetcore
```

执行以下命令，安装依赖：

s build --use-docker --dockerfile ./code/Dockerfile

输出示例：

Tips for next step
======================
* Invoke Event Function: s local invoke
* Invoke Http Function: s local start
* Deploy Resources: s deploy
End of method: build

执行以下命令，部署项目：

s deploy --push-registry acr-internet -y

输出示例：

There is auto config in the service: container-demo

Tips for next step
======================
* Display information of the deployed resource: s info
* Display metrics: s metrics
* Display logs: s logs
* Invoke remote function: s invoke
* Remove Service: s remove service
* Remove Function: s remove function
* Remove Trigger: s remove trigger
* Remove CustomDomain: s remove domain

执行结果

成功部署该项目后，您可以在执行输出中查看到函数计算生成的临时域名，通过该临时域名可以访问刚部署的应用，例如执行以下命令访问应用：

curl -v  http://aspdotnetcore-http-function.container-demo.188077086902****.cn-shenzhen.fc.devsapp.net/WeatherForecast
