Hi all,
I am new to Angular 2. I have an issue which I can't find the solution.
I am trying to develop a system which parses a file and send line by line
(after parsing as json) to server.
I have a loop which runs on the file and place a http.post request per
line.
In case of success, a second http.post to a different api is done.
In case of failure of the first call, i want to print the error and the
line in the file caused the error.
The problem is that since this is a asynch call, i can't make the second
http.post because the response return only after all calls are done. When
trying to get the row of the error, I get the last row in the file. snip
code:
for (var row = 0; row < rows.length; row++) {
let strBody = JSON.stringify(row);
res = this.http.post(url1, strBody, options)
if(success) {
strBody = JSON.stringify(res);
this.http.post(url2, strBody, options)
if(fail) {
//add error to table in html including row and strBody + reason
//the problem is when reaching this location row = rows.length
}
} else {
//add error to table in html including row and strBody + reason
//the problem is when reaching this location row = rows.length
}
}
I understand that the reason is the async nature of the call.
I appreciate your help
