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\') } }) } }) },
