如果直接調用HttpGet可以正常工作，但如果從Android活動調用時發出400響應

以下代碼可以正常工作，以便對我的寧靜Web服務進行HTTPS調用。在Eclipse中構建和執行一個簡單的Java應用程序。如果直接調用HttpGet可以正常工作，但如果從Android活動調用時發出400響應

package test;

@SuppressWarnings("unused") 
public class Test { 
    private String filePath; 

    private InputStream inputStream = null; 

    private DefaultHttpClient hc = null; 

    public Test(String filePath) { 
     this.filePath = filePath; 

     try { 
      this.inputStream = new FileInputStream(filePath); 

      if (this.inputStream != null) { 
       Certificate myCert = CertificateFactory.getInstance("X.509") 
         .generateCertificate(this.inputStream); 

       KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType()); 
       keyStore.load(null, null); 
       keyStore.setCertificateEntry("myCert", myCert); 

       SSLSocketFactory sf = new EasySSLSocketFactory(keyStore); 
       sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER); 

       HttpParams params = new BasicHttpParams(); 
       HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1); 
       HttpProtocolParams.setContentCharset(params, HTTP.UTF_8); 
       HttpProtocolParams.setUseExpectContinue(params, true); 

       SchemeRegistry registry = new SchemeRegistry(); 
       registry.register(new Scheme("http", PlainSocketFactory

       ClientConnectionManager ccm = new ThreadSafeClientConnManager(
         params, registry); 

       hc = new DefaultHttpClient(ccm, params); 

       // Prepare a request object 
       String url = "https://service.cashyr.com:8443/PolarBear-0.0.1-SNAPSHOT/get_deals_dist/33.7445273910949/-118.10924671590328/12/0/aaaa"; 
       HttpGet httpget = new HttpGet(url); 

       // Execute the request 
       HttpResponse response; 

       InputStream instream = null; 
       String data = null; 

//    // setSeeMoreDealsButton(context, false); 
       response = hc.execute(httpget); 
       HttpEntity entity = response.getEntity(); 

       instream = entity.getContent(); 
       if (instream != null) { 
        data = Utils.convertStreamToString(instream); 
        System.out.println(data); 
       } 
      } 
     } 
     catch (IOException e) { 
      e.printStackTrace();

     } 
    } 

    public static void main(String[] args) { 
     new Test("service.cashyr.com.crt"); 
    } 
}

現在，我創建了Eclipse的另一個Android應用程序（不活動僅僅是一個簡單的按鈕，並在代碼中的聽衆一個簡單的活動連接到該按鈕。反正我在點擊監聽器運行此活動，並在它會運行一個AsyncTask來逐字運行所提到的HTTPS調用，它會返回一個400響應。爲什麼會這樣呢？我完全搞不清楚，因爲我確信我遵循了所有的HTTPS過程，顯然不是完全確定，但它適用於直接的Java應用程序。爲什麼會這樣？請幫助!!!!

Android的活動如下：

OK鄉親們檢查了這一點保持它很簡單 - 它不是不好的劇本，不，先生.. 你的web.config可能有HTTP衝突400錯誤是要求加載沒有響應的網頁。所以你必須檢查一些小的細節輕微的bcs你知道腳本是好的，所以現在你必須檢查你的設置以及計算機和瀏覽器如何響應...

要解決此問題 首先清除您的DNS緩存並刪除cookies 1.重置您的網絡瀏覽器，然後轉到使用實際網址更改website.com腳本。 2.服務，與basicHttpBinding的 3.更換的WebHttpBinding確保您的標題行不長

記得保持它的簡單 如需更多幫助給我發電子郵件[email protected]
