How to Decompress GZip Streams from an HTTPClient Response in WCF and .NET Core?

Decompress GZip stream from HTTPClient response

When trying to integrate with APIs that return GZip-encoded JSON, it is critical to decode the compressed response before further processing. The following code snippet demonstrates how to decompress a GZip encoded response in a WCF service:

<code class="language-csharp">HttpClientHandler handler = new HttpClientHandler()
{
    AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate
};

using (var client = new HttpClient(handler))
{
    // 获取响应并进一步处理
}</code>

Note: It is recommended to avoid using using within a HttpClient block to prevent port exhaustion. Please consider using the following pattern:

<code class="language-csharp">private static HttpClient client = null;

ContructorMethod()
{
   if(client == null)
   {
        HttpClientHandler handler = new HttpClientHandler()
        {
            AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate
        };        
        client = new HttpClient(handler);
   }
// 你的代码            
 }</code>

Alternatively, for .Net Core 2.1 applications, it is recommended to use IHttpClientFactory and inject it in the startup code:

<code class="language-csharp">var timeout = Policy.TimeoutAsync<HttpResponseMessage>(
            TimeSpan.FromSeconds(60));

services.AddHttpClient<XApiClient>().ConfigurePrimaryHttpMessageHandler(() => new HttpClientHandler
        {
            AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate
        }).AddPolicyHandler(request => timeout);</code>
