如何发送正确的 HTTP 请求？

Question

我有一个现成的链接，可以使用 OTP 向用户的手机发送 SMS 消息。

但是，我正在使用这种方式，我想知道是否有更好的方式来发送请求。 另外，如何确保我得到 200 OK 响应。

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

response.Close();

您可以使用 HttpClient。

例子：

public class Client
{
  HttpClient _httpClient;
  public Client()
  {
    _httpClient=new HttpClient();
  }
  //async post,get request
  public async Task<string> sendGetRequest(string url)
  {
    var response= await _httpClient.GetAsync(url);
    if(response.IsSuccessStatusCode)
    {
     //if response has status code 200 do something
     //in this case I'm just converting the content of the response in string format
      string result=await response.Content.ReadStringAsync();
    }
    else
    {
      return "error";
    }
  }
  public async Task<string> sendPostRequest(string url,string bodyJson)
  {
    //Example sending a post request with json as body.
    var body=new StringContent(bodyJson, Encoding.UTF8, "application/json");
    var response= await _httpClient.PostAsync(url,body);
    if(response.IsSuccessStatusCode)
    {
     //if response has status code 200 do something
     //in this case I'm just converting the contntent of the response in string format
      string result=await response.Content.ReadStringAsync();
      return result;
    }
    else
    {
     return "error";
    }
  }

}
