在 Windows 应用商店应用程序中使用 httpclient 获取 UTF-8 响应

问题描述

我正在构建一个 Windows 应用商店应用，但我一直无法从 API 获得 UTF-8 响应.

I'm building a Windows Store app, but I'm stuck at getting a UTF-8 response from an API.

这是代码:

using (HttpClient client = new HttpClient())
{
    Uri url = new Uri(BaseUrl + "/me/lists");

    HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, url);
    request.Headers.Add("Accept", "application/json");
    HttpResponseMessage response = await client.SendRequestAsync(request);
    response.EnsureSuccessStatusCode();

    string responseString = await response.Content.ReadAsStringAsync();

    response.Dispose();
}

reponseString 总是包含奇怪的字符，应该是像 é 这样的重音符号，我尝试使用流，但我在一些示例中找到的 API 不存在于Windows RT.

The reponseString always contains strange characters which should be accents like é, and I tried using a stream, but the API I found in some examples don't exist in Windows RT.

改进的代码，仍然是同样的问题.

improved code, still same problem.

推荐答案

你可以使用 response.Content.ReadAsBufferAsync() 而不是直接使用 response.Content.ReadAsStringAsync()@Kiewic 指向的代码> 如下:

Instead of using response.Content.ReadAsStringAsync() directly you could use response.Content.ReadAsBufferAsync() pointed by @Kiewic as follows:

var buffer = await response.Content.ReadAsBufferAsync();
var byteArray = buffer.ToArray();
var responseString = Encoding.UTF8.GetString(byteArray, 0, byteArray.Length);

这在我的情况下有效，我想使用 UTF8 应该可以解决大部分问题.现在想想为什么没有办法使用 ReadAsStringAsync 来做到这一点:)

This is working in my case and I guess that using UTF8 should solve most of the issues. Now go figure why there is no way to do this using ReadAsStringAsync :)
