java验证iap支付收据

方法一：使用HttpsURLConnection（响应速度比方法二快）

public static JSONObject verifyReceipt1(String recepit) {
    	return verifyReceipt1("https://buy.itunes.apple.com/verifyReceipt", recepit);
    }
    
    public static JSONObject verifyReceipt1(String url, String receipt) {
    	try {
	        HttpsURLConnection cOnnection= (HttpsURLConnection) new URL(url).openConnection();  
	        connection.setRequestMethod("POST");  
	        connection.setDoOutput(true);  
	        connection.setAllowUserInteraction(false); 
	        PrintStream ps = new PrintStream(connection.getOutputStream());  
	        ps.print("{\"receipt-data\": \"" + receipt + "\"}");  
	        ps.close();  
	        BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));  
	        String str;  
	        StringBuffer sb = new StringBuffer();  
	        while ((str = br.readLine()) != null) {  
	            sb.append(str);    
	        }  
	        br.close();  
	        String resultStr = sb.toString();  
	        JSONObject result = JSONObject.parseObject(resultStr);
	        if (result != null && result.getInteger("status") == 21007) {
	        	return verifyReceipt1("https://sandbox.itunes.apple.com/verifyReceipt", receipt);
	        }
	        return result;
    	} catch (Exception e) {
    		e.printStackTrace();
    	}
        return null;
    }

方法二：使用HttpClient

public static JSONObject verifyReceipt2(String receipt) {
    	return verifyReceipt2("https://buy.itunes.apple.com/verifyReceipt", receipt);
    }
    
    public static JSONObject verifyReceipt2(String url, String receipt) {
    	HttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);
        try {
        	JSONObject data = new JSONObject();
        	data.put("receipt-data", receipt);
        	StringEntity entity = new StringEntity(data.toJSONString());
        	entity.setContentEncoding("utf-8");
        	entity.setContentType("application/json");
        	httpPost.setEntity(entity);
            HttpResponse respOnse= httpClient.execute(httpPost);
            HttpEntity httpEntity = response.getEntity();
            String resultStr = EntityUtils.toString(httpEntity);
            JSONObject result = JSONObject.parseObject(resultStr);
            httpPost.releaseConnection();
            if (result.getInteger("status") == 21007) {
            	return verifyReceipt2("https://sandbox.itunes.apple.com/verifyReceipt", receipt);
            }
            return result;
        } catch (Exception e) {
            e.printStackTrace();
        }
    	return null;
    }
