Detailed explanation of how to upload avatars using WeChat applet

<view class="edit-list">
　　<text class="list-name list-first">头像</text>
　　　　<view class="edit-righr-bar">
　　　　<image class="head-portrait" src="{{avatar}}" bindtap=&#39;changeAvatar&#39;></image>
　　</view>
</view>

// 切换头像
changeAvatar: function () {
var that = this;
// var childId = wx.getStorageSync("child_id");
// var token = wx.getStorageSync('token');
wx.chooseImage({
count: 1, // 最多可以选择的图片张数，默认9
sizeType: ['compressed'], // original 原图，compressed 压缩图，默认二者都有
sourceType: ['album', 'camera'], // album 从相册选图，camera 使用相机，默认二者都有
success: function (res) {
console.log(res.tempFilePaths + "修改页面")
var avatar = res.tempFilePaths;
that.setData({
avatar: avatar,
upAvatar:true
})
 
},
fail: function () {
// fail
},
complete: function () {
// complete
}
})
},
这是是调用上传头像uploadFile方法
// 上传头像
app.uploadimg({
url: 'URL地址',
path: avatar,
header: {
'Content-Type': 'multipart/form-data',
"Authorization": "Bearer " + token
},
isShow: false
});
 
上传头像代码uploadFile做了一个封装 代码放在APP.js里
//多张图片上传
uploadimg:function(data){
var that= this,
i=data.i ? data.i : 0,
success=data.success ? data.success : 0,
fail=data.fail ? data.fail : 0;
wx.uploadFile({
url: data.url,
filePath: data.path[i],
name: 'fileData',//这里根据自己的实际情况改
header: data.header,
formData: {
sequence:i+1
},
success: (resp) => {
success++;
console.log(resp)
console.log(i+"成功");
 
 
}
 
},
fail: (res) => {
fail++;
console.log('fail:' + i + "fail:" + fail);
},
complete: () => {
console.log(i);
i++;
if (i == data.path.length) { //当图片传完时，停止调用
console.log('执行完毕');
console.log('成功：' + success + " 失败：" + fail);
 
} else {//若图片还没有传完，则继续调用函数
console.log(i);
data.i = i;
data.success = success;
data.fail = fail;
that.uploadimg(data);
}

}
});
},
