c# - 从 Angular 2 到 ASP.NET ApiController 的 Http.post

Question

ASP.NET

[HttpPost]
[Route("apitest")]
public string apitest([FromBody]string str)
{
   Console.Writeline(str); // str is always null
   return null;
}

Angular 2:

var creds = "str='testst'" ;
var headers = new Headers();
    headers.append('Content-Type', 'application/x-www-form-urlencoded');

http.post('http://localhost:18937/apitest', creds, {
            headers: headers
        })
        .map(res => res.json())
        .subscribe(
            (res2) => {
                console.log('subsribe %o', res2)
            }
        );

我也试过 creds = {"str":"test"}; 没有标题 JSON.stringify() 等没有成功。如何将数据发布到 ASP.NET？

Answer 1

var creds = {
   str: 'testst'
};

$http.post('http://localhost:18937/apitest', JSON.stringify(creds));

Web API Controller 没有变化，它应该可以工作。
