Question

如何使用HttpWebRequest上传文件，知道我想通过相同的请求传递其他信息？

我要传递给请求的对象：

 public class product
    {
        public int Id { get; set; }

        public string Name { get; set; }

        public string DescriptionFilePath { get; set; }
    }

请求网址：http://api.mydomain.com/upload

谢谢！

尝试

public HttpWebResponse SendRequest(Product product){

    //create the request with the url
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://api.mydomain.com/upload");


    //set the put method
    request.method = "PUT";


    //serialize the product
    JavascriptSerializer serializer = new JavascriptSerializer();
    var body = serializer.Setialize(product);

    //write the serialized product to the request
    using(StreamWriter writer = new StreamWriter(request.GetRequestStream())){
        writer.write(body);
    }

    //execute the request and return the response
    return (HttpWebResponse) request.getResponse();
}

发送请求。如果您需要检索响应数据

    public string RetrieveResponseData(HttpWebResponse response){
       var result;
       using StreamReader reader = new StreamReader(response.GetResponseStream()){
          result = reader.ReadToEnd();
       }
       return result;
    }
