Hey I can't seem to get any results whilst using the req.body. Trying to get out the data from my mongodbdatabase to json format Here is my code:
My server file:
app.get('/api/category/posts', (req, res) => {
Post.find({ categoryId: req.body._id }, function(err, posts) {
res.json(posts);
});
});
Service file:
getPosts(_id): Observable<Post>{
return this.http.get<Post>(this.apiUrl +"/category/posts");
}
component.ts
this.appService.getPosts(_id)
.subscribe(data =>this.posts=data);

your api method is get method and you want _id in req.body. which is wrong.
you need to either change you get request to post in server file and service file both or try to pass _id in req.params or req.query:-
If you pass _id as req.query :-
your server code will be like:-
app.get('/api/category/posts', (req, res) => {
Post.find({ categoryId: req.query._id }, function(err, posts) {
res.json(posts);
});
});
service file
getPosts(_id): Observable<Post>{
return this.http.get<Post>(this.apiUrl +"/category/posts"+'?_id='+_id);
}
component.ts will be same.
and if you want to use post method to check for req.body then your code will be changed as following:-
your server code will be like:-
app.post('/api/category/posts', (req, res) => {
Post.find({ categoryId: req.body._id }, function(err, posts) {
res.json(posts);
}); });
service file
getPosts(_id): Observable<Post>{
return this.http.post<Post>(this.apiUrl +"/category/posts",{_id:_id});
}
component.ts will be same.
