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) } }) } }) },
