强制HttpClient使用Content-Type： text/xml

Question

这让我抓狂，我在任何地方设置ContentType标题，似乎都不能让它停止发送文本/纯文本。

查看Fiddler中的数据时，请求始终在请求：

POST超文本传输协议：/domain.comHTTP/1.1

内容类型：文本/纯文本；字符集=utf-8

using (var httpClient = new HttpClient())
{
    var request = new HttpRequestMessage(HttpMethod.Post, "http://domain.com");
        request.Content = new StringContent(Serialize(obj), Encoding.UTF8, "text/xml");
        request.Content.Headers.Clear();
        request.Content.Headers.ContentType = new MediaTypeHeaderValue("text/xml");
        request.Headers.Clear();
        request.Headers.Add("Content-Type","text/xml");
        var response = await httpClient.SendAsync(request);
        return  await response.Content.ReadAsStringAsync();
}

Answer 1

使用"应用程序/xml"而不是"文本/xml"

Answer 2

尝试设置默认请求标题：

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("text/xml"));

Answer 3

看起来你努力了：）这应该行得通。

using (var httpClient = new HttpClient())
{
    var request = new HttpRequestMessage(HttpMethod.Post, "http://domain.com");
    request.Content = new StringContent(Serialize(obj), Encoding.UTF8, "text/xml");
    var response = await httpClient.SendAsync(request);
    return  await response.Content.ReadAsStringAsync();
}
