WebAPI传递的post参数为null [英] WebAPI passed post parameters is null

问题描述

我正在使用WebAPI 2进行测试，并且创建了以下控制器方法.

I'm testing with WebAPI 2 and I have created the following controller method.

// POST api/values
public string Post([FromBody] string value)
{
    string returnValue = "Return: " + value ;
    return returnValue;
}

当我用提琴手发布以下消息时，方法参数始终返回null.

When i'm posting the following message with fiddler the method parameter keep returning null.

POST http://localhost:50814/api/Values/ HTTP/1.1
Host: localhost:50814
Content-Type: application/json
Content-Length: 14

{value: "New"}

我已经尽我所能简化了代码，但仍然保持为空.

I have simplyfied my code already as much as i can but still it stays null.

我认为我忽略了一些非常简单的内容，但是我没有主意.有人可以帮我吗?

I think I'm overlooking something very simple but i'm out of ideas. Could someone please help me?

推荐答案

如果要从Controller的Post方法中获取简单的String，请尝试仅发送以下内容:

If you're taking a simple String from your Controller's Post method, try sending just this:

POST http://localhost:50814/api/Values/ HTTP/1.1
Host: localhost:50814
Content-Type: application/json
Content-Length: 10

"MyString"
