"Lambda函数的路由找不到“错误运行与SAM局部Golang函数？

Question

我试图在Golang中编写一个Lambda函数(在我的MacBook上进行开发，同时运行Desktop )，遵循这的快速启动。我执行以下步骤：

1. 运行"sam -运行时go1.x -名称测试“以从模板生成函数。
2. 运行"make“以获取依赖项。
3. 运行"make“来构建生成到hello-world/hello-word的代码。
4. 运行"sam local start-api“。

一切看上去都是正确的：

Mounting HelloWorldFunction at http://127.0.0.1:3000/hello [GET]
You can now browse to the above endpoints to invoke your functions. You do not need to restart/reload SAM CLI while working on your functions, changes will be reflected instantly/automatically. You only need to restart SAM CLI if you update your AWS SAM template

但是当我卷曲端点时，我得到了502，我看到了一个错误：

我遗漏了什么？

这次聚会晚了，你可能已经解决了。在没有看到任何代码的情况下，您似乎已经发出了HEAD请求，而不是GET请求，而且我怀疑您没有HEAD方法的路由，只有GET。
