How to play with ajax data request of WeChat applet

Many students cannot find the location of the ajax data request of the WeChat applet. Here we list the ajax requests of the applet separately. The request of the WeChat applet is the wx.request API, wx.request (some Object parameters), WeChat applet is different from the browser's ajax request, and can directly make cross-domain requests without considering cross-domain issues.

Use the data request API officially provided by the mini program to initiate a data request

wx.request(OBJECT)

wx.request initiates an https request. A WeChat applet can only have 5 network request connections at the same time.

OBJECT parameter description:

wx.request({
  url: 'test.php',
  data: {
     x: '' ,
     y: ''
  },
  header: {
      'Content-Type': 'application/json'
  },
  success: function(res) {
    console.log(res.data)
  }
})

Then the code in the middle is a test. Here is an excerpt of a small part of the code for actual use. Modify yourself.

fetch('http://www.php.cn/json.php?typeid=34&page=1&pagesize=10')
    .then(function(response){
        if(response.status==200){
          that.data.page++;
          return response.json();
        }
    }).then(function(data){
      console.log(data);
        //更新数据
        that.setData({
            listArr:that.data.page==1 ? data : that.data.listArr.concat(data)
        })
        console.log(that.data.listArr);
    })
