由于长时间运行的SQL过程，Angular的POST而导致Nodejs错误

Question

On my site I currently use Angular / NodeJs/ and a SQL database. On the site I make a lot of calls from the site to NodeJs to the database and it works fine. However, when I run a stored procedure that takes a long time to process I get back the following in the console:

POST /job_bbb - - ms - -

From what I have seen on Google this is due to no response being sent back.

Any ideas on how to remedy this? Any help would be greatly appreciated.

Angular call to my service:

this.teradataService.getBBB(this.id).subscribe(bbbresults => this.bbbresults = bbbresults,
        error => console.log('ERROR!'),
        () => {
 });

Service HTTP POST:

  getBBB(id): Observable<[BBBResult]> { const url = 'http://localhost:3000/job_bbb'; const data = ({ id: id }); return this._http.post(url, data) .pipe( map((res) => { console.log(res); return <[BBBResult]> res; }) ); } 

Nodejs

 router.post('/job_bbb', function (req, res) { var id = req.body.id; var sql = "CALL Stored Proecedure Here;"; console.log(sql); return database.read(sql) .then((x) => { console.log(x) res.send(x); }) });

You might try increasing the server timeout for the server response. If the node server is Express:

 server.setTimeout(msecs);

Or probably better:

router.post('/job_bbb', function (req, res) {
       req.setTimeout(msecs);
       ....
});

The default timeout should be 2 minutes.
