I´m retrieving a String from backend:
String value = "{I am here}";
On my service:
getValue(): Observable<String> {
return this.http.get<String>(this.myURL);
}
On my component I´m subscribing:
String myMessage;
getValue(): void {
this.myService.getValue()
.subscribe(message=> {
this.myMessage= myMessage;
console.log("WHY NOT ENTER HERE?)
);
});
What I´m doing wrong for not even getting the message from console.log?
I guess you need to be specific about the responseType if you want to use string.
Here is the doc https://angular.io/guide/http#requesting-non-json-data
In your case, the getValueshould do this:
return this.http.get(this.myURL, { responseType: 'text' });
Note that you don't need to use <string>
From what I see, there is a mistake in your code, probably the reason you can't assign any value to myMessage:
Your code:
String myMessage;
getValue(): void {
this.myService.getValue()
.subscribe(message=> {
this.myMessage= myMessage;
console.log("WHY NOT ENTER HERE?)
);
});
It should be:
String myMessage;
getValue(): void {
this.myService.getValue()
.subscribe(message=> {
this.myMessage= message;
console.log("WHY NOT ENTER HERE?)
);
});
Notice the value assignment part in the callback function, you've used the wrong variable.
Hope it helps.
errorblock to your subscription and console in there to see the error.stringandString.
