Question

我正在使用AngularJS v1.2.25。当我通过POST将有效负载数据（字符串）发布到我的Web API时，我总是得到null。我用Postman（REST客户端）试了一下，然后我得到了一个字符串。我想知道这是否是一个错误，因为typeof变量是字符串。

这是我在Postman的HTTP请求（使用Fiddler）：

POST http://localhost:60858/logout HTTP/1.1

这是我的实际HTTP请求（通过AngularJS中的$ http）：

POST http://localhost:60858/logout HTTP/1.1
Host: localhost:60858
Connection: keep-alive
Content-Length: 88
Pragma: no-cache

我使用$ http方法的代码：

return $http[method](fullpath, data);

我在Web API中接收有效负载（字符串）的代码：

[Route("logout")]
[HttpPost]
public bool Logout([FromBody] string accessToken)
{
    var logout = _userService.LogUserOut(accessToken);
    return logout;
}

Answer 1

在数据字符串周围添加引号""。

if(typeof data === 'string') data = '"' + data + '"';

使用AngularJS将字符串数据发布到Web API会导致null
