从响应了HTTPClient解压缩的GZip流 [英] Decompressing GZip Stream from HTTPClient Response

问题描述

我试图连接到一个API，它返回的GZip编码的JSON，从WCF服务（WCF服务WCF服务）。我使用的了HTTPClient ，即可连接到API，并已经能够返回JSON对象为字符串。不过，我需要能够存储这个返回的数据在数据库中，因此我想最好的办法是恢复和JSON对象存储在沿着这些线路的数组或字节或东西。

什么我有麻烦特别是GZIP编码的解压缩，并一直在尝试许多不同的例子，但不能仍然得到它。

下面的代码是我如何建立我的连接，并得到响应，这是返回从API字符串的代码。

 公共字符串的getData（串富）
 {
字符串的URL =; 
 HttpClient的客户端=新的HttpClient（）; 
 HttpResponseMessage响应; 
串responseJsonContent; 
试
 {
 client.DefaultRequestHeaders.Accept.Add（新MediaTypeWithQualityHeaderValue（应用/ JSON））; 
响应= client.GetAsync（URL +富）。结果; 
 responseJsonContent = response.Content.ReadAsStringAsync（）结果。 
返回responseJsonContent; 
} 
赶上（异常前）
 {
 System.Windows.Forms.MessageBox.Show（ex.Message）; 
返回; 
} 
} 
  

我一直以下象这些 StackExchange API 时，MSDN 和一对夫妇的计算器，但我一直没能获得任何这些为我工作。

什么是实现这一目标的最佳方式，我在连上正确的轨道？

谢谢你们

解决方案

只需实例HttpClient的是这样的：

  HttpClientHandler处理程序=新HttpClientHandler（）
 {
 AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate 
}; 
 
使用（VAR的客户=新的HttpClient（处理））
 {
 //你的代码
} 
  

I am trying to connect to an api, that returns GZip encoded JSON, from a WCF service (WCF service to WCF service). I am using the HTTPClient to connect to the API and have been able to return the JSON object as a string. However I need to be able to store this returned data in a database and as such I figured the best way would be to return and store the JSON object in an array or byte or something along those lines.

What I am having trouble with specifically is the decompressing of the GZip encoding and have been trying lots of different example but still cant get it.

The below code is how I am establishing my connection and getting a response, this is the code that returns a string from the API.

    public string getData(string foo)
    {
        string url = "";
        HttpClient client = new HttpClient();
        HttpResponseMessage response;
        string responseJsonContent;
        try
        {
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            response = client.GetAsync(url + foo).Result;
            responseJsonContent = response.Content.ReadAsStringAsync().Result;
            return responseJsonContent;
        }
        catch (Exception ex)
        {
            System.Windows.Forms.MessageBox.Show(ex.Message);
            return "";
        }
    }

I have been following a few different examples like these StackExchange API, MSDN, and a couple on stackoverflow, but I haven't been able to get any of these to work for me.

What is the best way to accomplish this, am I even on the right track?

Thanks guys.

解决方案

Just instantiate HttpClient like this:

HttpClientHandler handler = new HttpClientHandler()
{
    AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate
};

using (var client = new HttpClient(handler))
{
    // your code
}
