WeChat applet uploads pictures to the server

This makes me a little confused, I don't know if I should write the header~
and then look at the code, I feel that there is no problem. Anyway, calling the API back and forth is just those few sentences:

   wx.uploadFile({
      url: 'url',
      filePath: that.data.imageSrc1[0],
      name: 'file',
      // formData: {
      //   'UUID':uuid.v1(),
      //   'phone':app.globalData.phone,
      //   'type':'before_picture',
      //   'missionID':this.data.missionID,
      //   'size':this.data.size1,
      //   'filename':'执行前照片'
      // },
      header: {
        'content-type': 'multipart/form-data' // 默认值
      },
      method: 'POST',
      success: function (res) {
        console.log(res.statusCode)

Don't know how to debug?
A statement to print the failure message is added to the code

fail:function(res){
        console.log(res)
      },

It prints as follows:

After Baidu for a long time, I saw another article saying that there is a problem with uploading and downloading files for local debugging of small programs, and it must be previewed~ Original

So a preview:

Well, continue to search for the ssl hand shake error problem and see one that says to configure TLS version 1.2 on the server and disable versions below 1.2.

Going around, I found a new problem with the certificate:
WeChat applet my way to fill the hole - request request:
1. Must use domain name, not ip
2. Must use port 443
3. Must have https
4. Must be in The domain name is configured in the background of the applet (the file must be configured separately, and the file can only be tested on the real machine)
5. The domain name must be recorded
6. Online detection of ssl certificate is missing
7. TLS must support version 1.2
