unity3d - System.DllNotFoundException：使用内容编码调用REST API时的MonoPosixHelper gzip

Question

使用响应标头调用REST API内容编码gzip与RestSharp导致问题。如果我使用Visual Studio将代码作为简单的ConsoleApplication执行，则没有问题，因此只有Unity无法处理此问题。任何有想法的人？

 var client = new RestClient("http://rest.sandbox-immobilienscout24.de"); 
    var request = new RestRequest("/restapi/api/search/v1.0/search/region", Method.GET); 
    client.ClearHandlers(); 
    request.AddQueryParameter("realestatetype", realestatetype); 
    request.AddQueryParameter("geocodes", geocodes); 
    request.AddHeader("Accept", "application/json"); 
    request.AddHeader("Systemauthorization", "blabla"); 
    IRestResponse response = client.Execute(request); 
    Debug.Log("search:" +response.ErrorException); 

响应头：

Cache-Control →private 
Content-Encoding →gzip 
Content-Type →application/json;charset=UTF-8 
Date →Sun, 06 Nov 2016 14:21:03 GMT 
Expires →Thu, 01 Jan 1970 01:00:00 CET 
L-IS24-ApiClient →blaKey 
L-IS24-RequestRefnum →06be3d11-6526-4664-acd1-0787dbd7d1f6 
Server →Apache 
Transfer-Encoding →chunked 
Vary →Accept-Encoding

统一2.6.1之后这个功能不会使用还有，请尝试使用WWW或WWWForm

Answer 2

您有几个选择与网站互动。包括

1. WWW

的WWW类可用于发送GET和POST请求到服务器 。如果您提供 postData参数，WWW类将默认使用GET并POST。

UnityWebRequest

的UnityWebRequest为统一的原WWW对象的替代品。 它提供了一个模块化系统，用于撰写HTTP请求和处理HTTP响应。 UnityWebRequest系统的主要目标是让 允许Unity游戏与现代Web后端进行交互。它也 支持高要求的功能，如分块的HTTP请求，流式传输 POST/PUT操作和完全控制HTTP头和动词。
