I have developed a REST service in Angular that sends back JSON response. To perform pattern matching and value replacement, I require the response as a string.
Currently, I am utilizing Angular 7 for this task. Below is an example of my service:
getUIData(): Observable<any> {
const url = `${this.baseUrl}/uiData`;
return this.http.get<any>(url).pipe(
catchError(this.handleError<any>('Get Data:'))
);
}
By default, the
HttpClientwill return a JSON Object.
In your specific case, you will need to convert it to a String. To do so, make some changes as shown below:
getUIData(): Observable<any> {
const url = `${this.baseUrl}/uiData`;
return this.http.get<any>(url).map( response => JSON.stringify(response.data)).
catchError(this.handleError<any>('Get Data:');
}
As suggested by @dcg, use the map function instead of pipe to convert your response data to a string within the Service method itself.
I trust that this solution will be helpful :).
There are two methods to achieve this:
1) Include the following request headers:
'Content-Type', 'text/plain; charset=utf-8'
2) Convert your response to a string format using the map operator
JSON.stringify(data);
Note that with the second method, the data will still be in JSON format but as a string.
