我想獲得使用java的網站的內容。像這樣我想要獲取使用java的網站的內容。但得到pxip錯誤

package javaTests; 

    import java.io.BufferedReader; 
    import java.io.IOException; 
    import java.io.InputStreamReader; 
    import java.net.URL; 

    import javax.net.ssl.HttpsURLConnection; 

public class PrintContent { 
    public static void main(String[] args) throws Exception { 
     String https_url = "https://api.precharge.net/charge"; 
     URL url; 
     url = new URL(https_url); 
     HttpsURLConnection con = (HttpsURLConnection)url.openConnection(); 

     if(con!=null){ 
     try { 

      System.out.println("****** Content of the URL ********");    
      BufferedReader br = 
      new BufferedReader(
       new InputStreamReader(con.getInputStream())); 

      String input; 

      while ((input = br.readLine()) != null){ 
       System.out.println(input); 
      } 
      br.close(); 

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

      } 


    } 
}

但我收到異常。

javax.net.ssl.SSLHandshakeException：sun.security.validator.ValidatorException：PKIX路徑建設失敗：sun.security.provider.certpath.SunCertPathBuilderException：無法找到有效的認證路徑要求的目標

請給一些建議如何解決這個問題。謝謝你advace。

我試着將證書複製到java的安全文件夾中。但它不起作用。也試過installcerticate.java類。

我不想把它標記爲重複的，因爲我不知道很多關於這個主題，但你看看：http://stackoverflow.com/questions/9210514/unable-to -find-valid-certification-path-to-requested-target-error-even-after-c –

@TomJonckheere。我不知道如何使用它。我將它寫成一個獨立的課程。不在服務器中。不知道這是否有幫助 – Raghavendra

好的，鏈接問題中的鏈接是否有幫助？ http://stackoverflow.com/questions/4062307/pkix-path-building-failed-unable-to-find-valid-certification-path-to-requested –

如果您未能在truststore中安裝證書，則可以使用此技巧來禁用SSL驗證。不應該在生產環境中使用。
