Access value from form data from request parameter in express js
Project: Codever - File: user.router.js
The values are present in the request.body which contains key-value pairs of data submitted in the request body.
In our case we access the userDisplayName with the following expression request.body.userDisplayName as in the example below:
usersRouter.post('/:userId/bookmarks/upload', keycloak.protect(),
uploadBookmarks.single("bookmarks" /* name attribute of <file> element in your form */),
async (request, response) => {
userIdTokenValidator.validateUserId(request);
const userDisplayName = request.body.userDisplayName;
const importResponse = await browserBookmarksImportService.imporBrowserBookmarks(request.params.userId, request.file.buffer, userDisplayName);
const str = JSON.stringify(importResponse, null, 2); // spacing level = 2
console.log(str);
return response.status(HttpStatus.OK).send(importResponse);
}
);
In angular the userDisplayName value has been appended to the FormData and submitted to a post request
via the Angular Http Client:
uploadBookmarks(userId: String, bookmarks: File, userDisplayName: string): Observable<any> {
const formData = new FormData();
formData.append('bookmarks', bookmarks);
formData.append('userDisplayName', userDisplayName);
return this.httpClient.post(`${this.usersApiBaseUrl}/${userId}/bookmarks/upload`, formData);
}
