c# - 强制 HttpClient 使用 Content-Type: text/xml

Question

这让我发疯，我在任何地方都设置了 ContentType 标头，但似乎无法让它停止发送文本/纯文本。

在 Fiddler 中观察数据，请求总是在请求：

POST http://domain.com HTTP/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

看起来你很努力:) 这应该可以工作。

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();
}

Answer 2

尝试设置默认请求标头：

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

Answer 3

使用“应用程序/xml”而不是“文本/xml”
