微信小程序，云端上传图片出错，求助大神！
微信小程序服务端API 上传图片出现错误。 服务端代码： const cloud = require('wx-server-sdk') cloud.init() const fs = require('fs') exports.main = async (event, context) => { const fileStream = fs.createReadStream(event.fileStream) return await cloud.uploadFile({ cloudPath: event.cloudPath, fileContent: fileStream,})} 用户端代码： var cloudPath = "sss/yyy/m000.jpg" var fileStream = 'cloud://暂时隐藏/my.jpg' wx.cloud.callFunction({ name: 'imgdoupload', data: { cloudPath: cloudPath, fileStream: fileStream }, success: res => { console.log('success--res') console.log(res) }, fail: res => { console.log(' fail--res') console.log(res) } },2000) 运行时出现上传失败： fail--res Error: errCode: -404011 cloud function execution error | errMsg: cloud.callFunction:fail requestID 708c4dfe-243a-11e9-ab66-525400235f2a, cloud function service error code -504002, error message ENOENT: no such file or directory, open 'cloud://暂时隐藏/my.jpg'; at cloud.callFunction api; at new e (WAService.js:1) at u (WAService.js:1) at Object.t.returnAsFinalCloudSDKError (WAService.js:1) at Function.success (WAService.js:1) at WAService.js:1 at Qe (WAService.js:1) at Bt.<anonymous> (WAService.js:1) at Bt.emit (WAService.js:1) at ji (WAService.js:1) at WAService.js:1 实在不知问题出现在哪里，还请大神不吝赐教！！！！！！
