C# 将 REST 调用的响应写入文本文件

Bry*_*ton 1 c# rest encoding messagebox text-files

我很难将我的休息调用中的请求内容写入 txt 文件。

我得到了一个响应,我可以将它输出到控制台,但我真的很想把它写到一个文本文件中。我倾向于将其视为编码问题,但我不确定在哪里设置或配置它。

我写的 Messagebox 和文件的内容都是空的。

static void Main(string[] args)
        {

            // Create the web request  
            HttpWebRequest request = WebRequest.Create("http://finance.yahoo.com/q/ecn") as HttpWebRequest;

            // Set type to POST  
            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";

            string query = "?s=PVSW";

            StringBuilder data = new StringBuilder();
            data.Append("&query=" + HttpUtility.UrlEncode(query));

            System.Windows.Forms.MessageBox.Show("Data = " + data.ToString());

            // Create a byte array of the data we want to send  
            byte[] byteData = UTF8Encoding.UTF8.GetBytes(data.ToString());

            // Set the content length in the request headers  
            request.ContentLength = byteData.Length;

            // Write data  
            using (Stream postStream = request.GetRequestStream())
            {
                postStream.Write(byteData, 0, byteData.Length);
            }

            // Get response  
            using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
            {
                // Get the response stream  
                StreamReader reader = new StreamReader(response.GetResponseStream());

                // Console application output  
                Console.WriteLine(reader.ReadToEnd());
                System.Windows.Forms.MessageBox.Show(reader.ReadToEnd());


                TextWriter tw = new StreamWriter("C:/Response.txt");

                // write a line of text to the file
                tw.WriteLine(reader.ReadToEnd());

                // close the stream
                tw.Close();

            }

        }

您正在调用reader.ReadToEnd()写入控制台,然后reader.ReadToEnd()再次调用MessageBox 和文件输出。您需要将数据从reader.ReadToEnd()临时变量(char[]或其他)中收集,然后将其提供给所有三个输出。
