详细代码:
博文仅针对这一个功能,其它的比如wxml和wxss设置,或者微信昵称的获取就不多介绍了。
找了很久也没有找到真实的图片链接地址的获取方式。。。如果有大佬知道如何弄,还请评论区指条明路。
本文用base64代替真实头像地址。后端有python和golang两种方式,供学习参考。
前端:
(不知道这个临时头像地址什么时候失效,改成你刚刚获取的临时地址,也就是下面代码的这一行换掉:
filePath: 'http://tmp/OYjz9xgN3sbZd18874aba0c54e580629f9df5623e3d9.jpeg',)
Page({
onLoad() {
wx.uploadFile({
url: 'http://127.0.0.1:8080/upload',
filePath: 'http://tmp/OYjz9xgN3sbZd18874aba0c54e580629f9df5623e3d9.jpeg',
name: 'file',
success: function (res) {
const responseData = JSON.parse(res.data);
console.log(responseData.base64_data);
}
});
},
});
python后端:
