HttpWebResponse: The remote server returned an error: (400) Bad Request

Question

我正在尝试 post 编写我的 gist 帐户代码。如果我写一行代码，它就可以工作。但是如果我写多行代码，我会得到错误。

例如运行 [1]:

Console.WriteLine();

例如不工作[2]:

python main.py

我无法post 第二个示例中的代码。我收到“远程服务器返回错误：(400) 错误请求。”错误。

也许你需要知道

textBox1.Text 用于要点描述

richTextBox1.Text 用于内容正文 --> 不适用于多行 post 数据

我的代码如下：

String jsonMessage = "{ \"description\": \"" +textBox1.Text + "\",  \"public\": true,"
                   + "\"files\": {   \"file1.cs\": {"
                   + "\"content\":\""+ richTextBox1.Text.ToString() + "\"  } }}";

            String _url = "https://api.github.com/gists";

            HttpWebRequest req = WebRequest.Create(new Uri(_url)) as HttpWebRequest;


            String userName = "GITHUB_USERNAME";
            String userPassword = "GITHUB_PASSWORD";
            string authInfo = userName + ":" + userPassword;
            authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));

            req.Method = "POST";
            req.ContentType = "application/json";
            req.Headers.Add("Authorization", "Basic " + authInfo);
            req.UserAgent = "Test-Agent";
            StreamWriter writer = new StreamWriter(req.GetRequestStream());

            //MessageBox.Show(jsonMessage);
            writer.Write(jsonMessage);
            writer.Close();

            string result = null;

            using (HttpWebResponse resp = req.GetResponse() as HttpWebResponse) // Error Line
            {
                StreamReader reader = new StreamReader(resp.GetResponseStream());
                result = reader.ReadToEnd();
                var jo = JObject.Parse(result);
                //MessageBox.Show(jo["url"].ToString());
                textBox2.Text = "https://gist.github.com/" + jo["id"].ToString();

            }

我该如何解决这个问题？我该怎么办？

谢谢！

richTextBox1.Text for content body --> not working for multiline post datas

新行字符应该在 json 字符串中转义...因为您使用字符串操作形成 json，所以您会得到一个包含多行内容的无效 json...

你可以轻松测试它here。

创建 json 字符串的正确方法是使用 json 序列化程序。由于您已经使用了 Json.Net，您可以像

var json = JsonConvert.SerializeObject(
                new
                {
                    description = textBox1.Text,
                    content = richTextBox1.Text,
                    @public = true
                }
            );
