wx.request

##When looking at the document, the sample template is provided as follows:

wx.request({
  url: 'test.php', //仅为示例，并非真实的接口地址
  data: {
     x: '' ,
     y: ''
  },
  header: {    'content-type': 'application/json' // 默认值
  },
  success: function(res) {
    console.log(res.data)
  }})

      url: '复制的链接', //仅为示例，并非真实的接口地址
      data: {
        x: '',
        y: ''
      },
      header: {
        'content-type': 'application/json' // 默认值
      },
      success: function (res) {
