微信小程序开发入门1——异步请求与数据接收

1. 1. 在微信小程序的onload()方法内，通过wx.request方法进行请求。类似于jsp中的ajax请求。代码如下：

• onLoad: function (options) {

  var that = this;

  that.data.courseId = options.courseId;

  console.log( "管理员查看所有打卡");

  wx.request({

  url: app.globalData.myUrl2 + 'minisoftware/helloword/managerGetDaka.do',

  data: {

  "dateStr": "today",

  "courseId": that.data.courseId,

  },

  dataType: 'json',

  header: { 'content-type': 'application/json;charset=ISO-8859-1' },

  method: 'post',

  success(e) {

  console.log(e)

  }

  })
          
  

      2.在java控制层，编写对应方法。

• @RequestMapping(value = "/managerGetDaka", method = RequestMethod.POST,produces = "text/plain;charset=UTF-8")
  public @ResponseBody String managerGetDaka(@RequestBody GetDakaParam param,HttpServletRequest request){
  JSONObject jo = new JSONObject();
  jo.put("videoUrl", "test");
  return jo.toString;
  }
