我正在尝试upload image，它已在S3中正确上传，数据库条目也运行良好，然后输入正确的else condition，但未发送任何响应。
它进入if (req.body.category === 'profile') {并到达else condition
一切正常，但是在浏览器中测试时我没有收到响应。
在crome控制台中，我看到状态=> failed
但是它在POSTMAN
router.post('/attachment', async (req, res) => {
const singleUpload = await fileUpload.single('fileUpload')
singleUpload(req, res, async (err) => {
console.log('came to single upload')
if (err) {
console.log(err)
let error = {}
error.isError = true
error.message = err.message
res.status(500).json(error)
} else {
console.log('stored to s3')
console.log(req.body.id)
console.log(req.body.category)
console.log(req.file)
if (req.body.category === 'profile') {
let result = await helper.setUserPhoto(req.body.id, req.file.location)
console.log(`result: ${result}`)
if (result === null) {
let error = {}
error.isError = true
error.message = 'Unable to store url of user,try after some time'
res.status(500).json(error)
} else {
let output = {
originalname: req.file.originalname,
size: req.file.size,
location: req.file.location
}
console.log(output)
//IT REACHES HERE, EVEN OUTPUT CONSOLE WORKS FINE
res.status(200).json(output)
}
} else if (req.body.category === 'logo') {
let result = await helper.setUserCompanyLogo(req.body.id, req.file.location)
if (result === null) {
let error = {}
error.isError = true
error.message = 'Unable to store url of user,try after some time'
res.status(500).json(error)
} else {
let output = {
originalname: req.file.originalname,
size: req.file.size,
location: req.file.location
}
res.status(200).json(output)
}
} else {
res.status(400).json({
isError: true,
message: 'category is not valid'
})
}
}
})
})
刚才我尝试了https://netlog-viewer.appspot.com/#events
