轉換cURL命令成純Java

Question

我有一個谷歌的令牌，並用它，我要求從谷歌認證的URL與以下cURL命令：

curl --data 'accountType=&Email=&has_permission=1&Token= + $$TOKEN$$ + &service=weblogin%3Acontinue%3Dhttps%253A//www.google.com/dashboard/&source=&androidId=&app=&client_sig=&device_country=&operatorCountry=&lang=&RefreshServices=' -k 'https://android.clients.google.com/auth' 

我如何轉換該命令爲純java命令與URL連接或Apache HTTP庫？這樣我就不必再使用cURL二進制。

我看到了幾個例子，但我面臨POST參數的一些麻煩。我無法得到是正確的。

我的Java嘗試：

$$ TOKEN $$ - >必須由真正的令牌替換。

      post.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
      HttpResponse response = client.execute(post); 
      BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent())); 

      String line = ""; 
      while ((line = rd.readLine()) != null) { 
      System.out.println(line); 

      } 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 
} 

我的Eclipse控制檯打印：

Url=https://www.google.com/accounts/ErrorMsg?id=unknown 
Error=Unknown

      HttpsURLConnection.setDefaultHostnameVerifier(hv); 
     } catch (Exception e) { 
      // Do nothing

    } 
} 

我不得不添加SSL證書驗證，然後它的工作。

如果您使用java.net.HttpURLConnection，則可以將發佈數據的字節寫入輸出流。所以你所要做的就是把你的--data轉換成字節並寫入流中。
