将 python 个 http 代码转换为 C#

Question

我在 python

中有这段代码

response = requests.post(
    "https://gateway.watsonplatform.net/personality-insights/api/v2/profile",
    auth = ("username", "password"),
    headers = {"content-type": "text/plain"},
    data = "your text goes here"
)

jsonProfile = json.loads(response.text)

我正在尝试将其转换为 C#，下面是我的代码：

public void getRequest() {
        string url = "https://gateway.watsonplatform.net/personality-insights/api/v2/profile";
        using (var client = new WebClient())
        {
            var values = new NameValueCollection();
            values["username"] = username;
            values["password"] = password;
            values["content-type"] = "text/plain";
            values["data"] = getTestWords(@"D:\Userfiles\tchaiyaphan\Documents\API and Intelligence\storyTestWord.txt");

            var response = client.UploadValues(url, values);

            var responseString = Encoding.Default.GetString(response);
        }
    }

我不知道如何处理页眉部分，所以我把它漏掉了。当我运行代码时，它给了我一个 401 错误。我不知道该怎么办！

Answer 1

问题是您的代码将用户名和密码作为 POST 数据发送，而不是使用正确的 HTTP 授权 header。

client.Credentials = new NetworkCredential(username, password);

Answer 2

虽然 ThiefMaster 设法让我通过了身份验证，但这次它给了我一个不同的错误（415 Un-supported media type）所以我决定采用不同的方法并且它有效。

var request = (HttpWebRequest)WebRequest.Create("https://gateway.watsonplatform.net/personality-insights/api/v2/profile");

        var postData = getTestWords(@"D:\Userfiles\tchaiyaphan\Documents\API and Intelligence\storyTestWord.txt");

        var data = Encoding.ASCII.GetBytes(postData);

        request.Method = "POST";
        request.ContentType = "text/plain";
        request.ContentLength = data.Length;
        request.Credentials = new NetworkCredential(username, password);

        using (var stream = request.GetRequestStream())
        {
            stream.Write(data, 0, data.Length);
        }

        var response = (HttpWebResponse)request.GetResponse();

        var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
