我的控制器中有一個NestJs專案，我接受Express.Multer.File，但我需要將其發送到另一臺服務器。如何將其轉換為Blob以傳遞給FormData？
#action in my controller
@Post('/upload')
@UseInterceptors(FileInterceptor('avatar'))
async uploadUserProfileAvatar(@UploadedFile() file: Express.Multer.File){
console.log(file)
let blob = new Blob(file.mimetype)
let formData = new FormData()
//can't set because file is not Blob
formData.append('file',file)
let request$ = this.httpService.post('http://test_server/file',formData,{headers:{
'Content-Type':'multipart/form-data'
}}).pipe(
map(response => response.data)
)
request$.subscribe( response => {
console.log(response)
return response
})
}
我將不勝感激每一個答案！
編輯：
再次感謝你的幫助！結果，我設法以這種方式成功發送了代碼：
@Post('/upload')
@UseInterceptors(FileInterceptor('avatar'))
async uploadUserProfileAvatar(@UploadedFile() file: Express.Multer.File){
const FormData = require('form-data');
const formData = new FormData();
formData.append('file', Buffer.from(file.buffer) , file.originalname);
let request$ = this.httpService.post('http://nginx_files/file',formData,{headers:formData.getHeaders()}).pipe(
map(response => response.data)
)
request$.subscribe( response => {
console.log(response)
return response
})
}
uj5u.com熱心網友回復：
使用這樣的formdata包：
const FormData = require('form-data');
const formData = new FormData();
formData.append('file', fileContent, 'file_name.ext');
let request$ = this.httpService.post('http://test_server/file',
formData,
{ headers: formData.getHeaders() }
).pipe(
map(response => response.data)
)
