c# - 如何获取 Web API IHttpActionResult 响应并序列化 c#

Question

我正在尝试“响应、序列化和使用”Web API，我以前从未编写过 Web API。

我有以下 Web API:

 [HttpGet]     
 public IHttpActionResult SendMsg(string yourName)       
 {

        var result = "Hi " + yourName;
        if (result == null)
        {
            return NotFound();
        }
        return Ok(result);
  }

我正在尝试使用此代码获取响应:

    private void ResponseWebAPI(string strApiAddress)
    {
        HttpWebRequest request = WebRequest.Create(strApiAddress) as HttpWebRequest;
        HttpWebResponse response = request.GetResponse() as HttpWebResponse;

        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.Load(response.GetResponseStream());

    }

我收到的响应没有任何问题，但是当我加载响应时出现以下错误:

Data at the root level is invalid. Line 1, position 1

Answer 1

试试这个

private void ResponseWebAPI(string strApiAddress) {
    var request = WebRequest.Create(strApiAddress) as HttpWebRequest;
    var response = request.GetResponse() as HttpWebResponse;

    using (Stream stream = response.GetResponseStream()) {
        var reader = new StreamReader(stream, Encoding.UTF8);
        var responseString = reader.ReadToEnd();
        var xmlDoc = new XmlDocument();
        xmlDoc.LoadXml(responseString);
    }

}
