HTTP请求接口返回数据

直接上代码

public String getHttpInterface(String path){
        BufferedReader in = null;
        StringBuffer result = null;
        try {
            URL url = new URL(path);
            //打开和url之间的连接
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
            connection.setRequestProperty("Charset", "utf-8");
            connection.connect();

            result = new StringBuffer();
            //读取URL的响应
            in = new BufferedReader(new InputStreamReader(
                    connection.getInputStream(),"utf-8"));
            String line;
            while ((line = in.readLine()) != null) {
                result.append(line);
            }
            return result.toString();
        } catch (Exception e) {
            e.printStackTrace();
        }finally {
            try {
                if (in != null) {
                    in.close();
                }
            } catch (Exception e2) {
                e2.printStackTrace();
            }
        }
        return null;
    }

返回结果为接口给你的字符串，PATH为请求地址
