小程序请求Django后台及路由跳转

小程序请求Django后台（wx.requests）

小程序：

# pages/test1/test1.wxml
点我
    
# pages/test1/test1.js  
Page({
    req:function(){
    wx.request({
      url: 'http://127.0.0.1:8000/test',
      data:{"name":"zhang"}, // 向后端发送的数据，后端通过request.data拿到该数据
      method:"POST",
      header:{
        "content-type":'application/json'
      },
      success(res) {
        console.log(res)
      }
    })
  }
})
'''
回调的结果res:
