Question

尝试运行发布请求并且即使传递数据也没有数据被发送？后端报告未发送任何帖子数据，并且我检查了它似乎没有发送？

我已经仔细检查了所有内容，但我不明白为什么？ StackOverflow不断要求我提供更多描述，对不起冗长的解释。

var response = HttpFactory.PerformHttpWebRequest("http://localhost:8000/api/cache"
new Dictionary<string, string>()
{
    { "item", Username },
    { "name", Name },
    { "picture", Picture },
    { "additional_data", JsonConvert.SerializeObject(MetaData) },
}, "POST");



private static HttpResponse PerformHttpWebRequest(
    string url, 
    IDictionary<string, string> data = default, 
    string method = "GET"
)
{
    if (method == "GET" && data != null)
    {
        url += "?" + string.Join("&", data.Select((x) => x.Key + "=" + x.Value));
    }

    LAST_PROCESSED = url;

    try
    {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

        request.Method = method;
        request.ContentType = "application/json; charset=UTF-8";
        request.Accept = "application/json";

        if (data != null && method == "POST")
        {
            byte[] postData = Encoding.ASCII.GetBytes(string.Join("&", data.Select((x) => x.Key + "=" + x.Value)));

            using (Stream stream = request.GetRequestStream())
            {
                stream.Write(postData, 0, postData.Length);
            }
        }

        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
        using (Stream stream = response.GetResponseStream())
        using (StreamReader reader = new StreamReader(stream))
        {
            return new HttpResponse(url, response.StatusCode, reader.ReadToEnd());
        }   
    }
    catch (WebException we)
    {
        var response = (HttpWebResponse)we.Response;

        if (response == null)
        {
            return new HttpResponse(url, default, default, we);
        }

        var reponseStream = new StreamReader(we.Response.GetResponseStream());

        return new HttpResponse(url, response.StatusCode, reponseStream.ReadToEnd());
    }
    catch (Exception e)
    {
        return new HttpResponse(url, default, default, e);
    }
}

您正在设置request.ContentType = "application/json; charset=UTF-8";，但实际上是在发布application/x-www-form-urlencoded。

您可以尝试更改吗？

发布数据未正确发送到后端api？
