url为请求地址,json为需要上传的对象的JSONObject,encoding为编码方式,一般为"utf-8"。该函数会将请求结果作为字符串返回。
调用代码示例如下:
String url = "http://localhost:8079/YiDongBusiness/sendVerificationCode";
JSONObject json = (JSONObject) JSONObject.toJSON(shortMessage);
String encoding = "utf-8";
System.out.println(ShortMessageServiceImpl.send(url, json, encoding));
