发送post请求，通过回调获取相应参数；在发送的url中添加参数，通过回调，获取其相应的参数值：
eg：
1、快递100发送post请求，进行订阅：
public class ExpressRegisterServiceImpl {
// 回调接口的地址
private static final String CALLBACKURL = "http://127.0.0.1/api/v2/expresscallback/kuaidi100/expressNotify";
public boolean registerToExpress100(ExpressOrderMapping expressOrderMapping) {
String mURL = CALLBACKURL + "?mappingid=" + expressOrderMapping.getId();//url获取参数
taskRequest.getParameters().put("callbackurl", mURL);
// create Map
Map<String, String> p = new HashMap<String, String>();
p.put("schema", schema);
p.put("param", JacksonHelper.toJSON(taskRequest));
String ret = HttpUtil.post(url, p);//发送post请求
}
}
2、订阅回调，获取url传参：
@RestController
@RequestMapping("api")
public class ExpressCallbackController {
@RequestMapping(value = "/v2/expresscallback/kuaidi100/expressNotify", method = RequestMethod.POST)
public Object expressNotify(HttpServletRequest request, HttpServletResponse response) {
String mappingid = request.getParameter("mappingid");
String content = request.getParameter("param");
}
}
3、通过postman验证：
