尝试发送帖子并总是收到错误的请求

Question

我正在尝试发送如下帖子：

curl -X POST https://app.referralsaasquatch.com/api/v1/{tenant_alias}/rewards/account/{accountId}/user/{userId} \
       -u :API_KEY \
       -H "Content-Type: application/json" \
       -d '{
   "type": "CREDIT",
   "cancellable": true,
   "unit": 'credit-in-cents',
   "assignedCredit": 150*100,
   "currency": EUR
}'

• API_KEY：API_KEY_VALUE
• TENANT_ALIAS：test_ai38kl5mysg8n

• 授权：基本 Base64.encode(API_KEY)

  public static void executePost() {
  
  // TODO code application logic here
  String STRURL = "https://app.referralsaasquatch.com/api/v1/" + "test_ai38kl5mysg8n" + "/rewards/account/"
          + ActionGetRsqInfo.IDINTIFIRE + "/user/" + ActionGetRsqInfo.IDINTIFIRE;
  
  System.out.println(STRURL);
  
  URL url;
  HttpURLConnection urlConn = null;
  StringBuilder sb = new StringBuilder();

              while ((line = br.readLine()) != null) {
                  sb.append(line + "\n");
              }

          else {
              System.out.println("bad URL    " + ((HttpURLConnection) urlConn).getResponseMessage());
  
          }
  
      }
  
      catch (MalformedURLException e) {
  
          e.printStackTrace();
      } catch (IOException e) {
  
          e.printStackTrace();
      }
  
      catch (JSONException e) {
          // TODO Auto-generated catch block

      }
  
      finally {
          if (urlConn != null)
              urlConn.disconnect();

您不应该使用 HttpURLConnection 连接到 https，尝试使用 HttpsURLConnection 或其他支持 https 的客户端

URL urlConnection = new URL(url);
HttpsURLConnection connection = (HttpsURLConnection)urlConnection.openConnection();

也可以尝试使用

  OutputStreamWriter printout= new OutputStreamWriter(connection.getOutputStream());
  printout.write(requestObject.toString());

而不是

 printout = new DataOutputStream(urlConn.getOutputStream());
 printout.writeBytes(URLEncoder.encode(json.toString(), "UTF-8"));
