Softlayer API錯誤「java.net.SocketException：連接重置」

Question

我正在使用java.net API來請求softlayer API。

String url = "https://api.softlayer.com/rest/v3.1/SoftLayer_Account/getInvoices.json"; 
String query = "objectFilter={\"invoices\":{\"createDate\":{\"operation\":\"betweenDate\",\"options\":[{\"name\":\"startDate\",\"value\":[\"04/01/2017 17:50:40\"]},{\"name\":\"endDate\",\"value\":[\"06/01/2017 17:50:40\"]}]}}}"; 
HttpsURLConnection conn = (HttpsURLConnection) new URL(url + "?" + query).openConnection(); 

我得到這個錯誤

    at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:254) 

我怎樣才能解決這個問題？

Unfortunetaly 對象過濾尚未在SoftLayer的Java API的客戶端來實現，目前有關於這一個開放的問題，請參見：

https://github.com/softlayer/softlayer-java/issues/30

同時，您可以：

藉機休息一下請求如下，以檢索所需信息：

https://[username]:[apiKey]@api.softlayer.com/rest/v3.1/SoftLayer_Account/getInvoices?objectFilter={"invoices":{"createDate":{"operation":"betweenDate","options":[{"name":"startDate","value":["04/01/2017 17:50:40"]},{"name":"endDate","value":["06/01/2017 17:50:40"]}]}}} 

檢索getInvoices結果，然後使用自己的代碼對其進行過濾;或使用任何其他的SoftLayer API客戶支持的編程語言，請參閱以下內容：

問題是由於在請求發送的字符，字符，例如[] {}：「」，所有的他們必須編碼，要做到這一點，你可以使用方法URLEncoder.encode。

URLEncoder.encode(filter,"UTF-8"); 

下面是我用來解決問題的java代碼。這個例子是基於https://www.mkyong.com/webservices/jax-rs/restfull-java-client-with-java-net-url/

public static void main(String[] args) { 

     // Define user credentials 
     String username = "set me"; 
     String apikey = "set me"; 

     // Define Service url, method and header params 
     String url = "https://api.softlayer.com/rest/v3.1/SoftLayer_Account/getInvoices.json"; 
     String filter = "{\"invoices\":{\"createDate\":{\"operation\":\"betweenDate\",\"options\":[{\"name\":\"startDate\",\"value\":[\"04/01/2017 17:50:40\"]},{\"name\":\"endDate\",\"value\":[\"06/01/2017 17:50:40\"]}]}}}"; 

     try { 
      String encodedFilter = URLEncoder.encode(filter,"UTF-8"); 

      // Build the URL request 
      URL urlRequest = new URL(url + "?objectFilter=" + encodedFilter); 

      HttpsURLConnection conn = (HttpsURLConnection) urlRequest.openConnection(); 

      // Encode user credentials to Base64 form 
      String authString = username + ":" + apikey; 
      String authStringEnc = new String(Base64.getEncoder().encode(authString.getBytes())); 

      // Add authentication, request method and property 
      conn.setRequestProperty("Authorization", "Basic " + authStringEnc); 
      conn.setRequestMethod("GET"); 
      conn.setRequestProperty("Accept", "application/json"); 


      if (conn.getResponseCode() != 200) { 
       System.out.println("Failed : HTTP error code : " + conn.getResponseCode()); 
      } 

      BufferedReader br = new BufferedReader(new InputStreamReader((conn.getInputStream()))); 

      String output; 
      System.out.println("Output from Server .... \n"); 
      while ((output = br.readLine()) != null) { 
       System.out.println(output); 
      } 

      conn.disconnect(); 

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