微信小程序wx.uploadFile的两个坑

setImage:function(e){
var _this = this //坑1
wx.chooseImage({
count: 1,
sizeType: [\'original\', \'compressed\'],
sourceType: [\'album\', \'camera\'],
success: function (res) {
var tempFilePaths = res.tempFilePaths
console.log(tempFilePaths)
wx.uploadFile({
url: app.globalData.myhost+\'customer-header?access_token=\'+app.globalData.itoken,
filePath: tempFilePaths[0],
name: \'uploadFile\',
formData: {
\'userId\': app.globalData.iuserId
},
success: function (res) {var data = JSON.parse(res.data) //坑2:与wx.request不同,wx.uploadFile返回的是[字符串],需要自己转为JSON格式
console.log(\'上传成功\')
_this.setData({ //坑1:wx.uploadFile本身有一个this,所以要通过外部var _this = this 把this带进来
headerImageUrl: data.headerImageUrl
})
console.log(\'刷新成功\')
}
})
}
})
},
