Angular HTTP 请求获取响应正文

Question

I am currently trying to figure out how to get the response body. I can see it in the browser's network console as an array of strings(this is what i would like to get) but using my code will only return an Object:

this.http.request(req).subscribe(event => {
            if (event.type === HttpEventType.UploadProgress) {
                const percentDone = Math.round(100 * event.loaded / event.total);
                console.log(`File is ${percentDone}% uploaded.`);
            } else if (event instanceof HttpResponse) {
                console.log('File is completely uploaded!');
                console.log('resp: ' + event.body);
            }
          });

It is an POST request.

This is the log:

resp: [object Object]

You need to use JSON.stringify to see the actual content

 console.log('resp: ' + JSON.stringify(event.body));

if you want to access particular field from the response, use JSON.parse to convert to Object

let filename = (JSON.parse(event.body)).fileName;
