如何配置我的操作方法，该方法应具有相同的路由，相同的控制器，但dotnetcore webapi中只有动词更改

Question

我想调用给定的同一控制器的各个动作方法，两个动作方法的路由都相同，但是只有http动词会发生变化。

[attr.disabled]

当我尝试进行get调用时，将返回适当方法的返回值。但是，当我尝试进行后期呼叫时，这将导致500内部服务器错误。

有没有一种方法可以同时使用相同的路由，相同的控制器但使用不同的httpverb来工作？

Answer 1

您对Rest API有误解。

使用GET动词时，应通过url参数传递数据。使用POST动词时，建议的方法是通过主体传递数据。

因此您可以将方法标头转换为：

    [HttpGet("{param1}/{param2}")]
    public string MethodWithGet(string param1, string param2)
    {
       return interalgetmethodcall(param1, param2);
    }

    [HttpPost]
    public string MethodWithPost([FromBody]string param1, [FromBody]string param2,[FromBody] dynamic datafrombody)
    {
       return interalpostmethodcall(param1, param2, datafrombody.toString());
    }

您将这样呼叫的第一个：

fetch(`/${param1}/${param2}`, {method: 'GET'});

第二个是：

var formData = new FormData();
formData.append("param1", param1);
formData.append("param2", param2);
formData.append("datafrombody", datafrombody);
fetch('/', {method: 'POST', body: formData});

当我尝试进行get调用时，将返回适当方法的返回值。但是，当我尝试进行后期呼叫时，这将导致500内部服务器错误。

您可以使用相同的路由，相同的控制器以及不同的httpverb。

这是我的测试结果。

interalpostmethodcall(param1, param2, datafrombody.toString());

此外，启用 interalpostmethodcall(param1, param2, datafrombody?.toString()); 中的app.UseDeveloperExceptionPage();来检查详细信息错误。
