// 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9sizeType: ['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);}}});},
