Question

我正在尝试发布以下请求，但收到"Unsupported Media Type"响应。我将Content-Type设置为application/json。任何帮助将不胜感激。

var json = JsonConvert.SerializeObject(request);
var stringContent = new StringContent(json, UnicodeEncoding.UTF8, "application/json");
MyResult result = new MyResult();
using (var client = new HttpClient())
{
    client.BaseAddress = new Uri(baseurl);
    client.DefaultRequestHeaders.Clear();               
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", base64ApiKey);
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));               
    HttpResponseMessage Res = await client.PostAsync(method, stringContent);
    if (Res.IsSuccessStatusCode)
    {
        var response = Res.Content.ReadAsStringAsync().Result;
        result = JsonConvert.DeserializeObject<MyResult>(response);
    }               
}

在检查了从我的代码发送来的原始数据之后，我看到此行正在添加字符集：

var stringContent = new StringContent(json, UnicodeEncoding.UTF8, "application/json");

发送的实际数据如下：

Content-Type: application/json; charset=utf-8

我需要使用以下命令从请求中删除字符集：

stringContent.Headers.ContentType.CharSet = string.Empty;

HttpClient-“不支持的媒体类型”
