How to solve the problem of request 400 in WeChat applet

WeChat API

• 对于header['content-type'] 为application/json 的数据，会对数据进行json序列化
  对于header['content-type'] 为 application/x-www-form-urlencoded 的数据，会哦将数据转换成query string （encodeURIComponent(k)=encodeURIComponent(v)&encodeURIComponent(k)=encodeURIComponent(v)...）

Listing code

The following is my WeChat account List of codes in the program

//请求URL
    wx.request({
      url:"https://api.douban.com/v2/movie/top250",      data:{},      header: {      'content-type': 'application/json' // 默认值
      },
      success:function(res){
        wx.hideToast();
        console.log(res.data);
      }
    });

Compilation error

The following are the errors that occur after compilation

Solving the problem

I modified the header in the request as follows:

 header: {        //'content-type': 'application/json' // 默认值
        //这里修改json为text   json的话请求时会返回400(bad request)
        'content-type': 'application/texts'
      },

After modification, debugging is as follows
