How can I get access to the Angular 2 http response body without converting it to string or json?
Solution 1
There's a much simpler solution to accessing the body as a string which I haven't seen documented anywhere:
let body = res.text()
Solution 2
Addon to @StudioLE. You may use json() method to return data as json.
let body = res.json()
Solution 3
Since I found this question while running into the same problem (and Angular's documentation is not updated as of today) you can now use:
let blob = new Blob([response.arrayBuffer()], { type: contentType });
Another workaround if you for some reason are on an old version of Angular 2 is:
let blob = new Blob([(<any> response)._body], { type: contentType });
Solution 4
set the responseType of requestoptions. That will make the response.blob() method work.
let headers = this.getAuthorizationHeader();
headers.append("Accept", "application/octet-stream");
return this.http
.get(url, new RequestOptions({ headers: headers, responseType: ResponseContentType.Blob }))
.map((res: Response): Blob => {
return res.ok ? res.blob() : undefined;
});
Solution 5
I can't see no other solutions before the following PR is merged:
Whereas you have a compilation error, the field can be used at runtime...

I would like to copy a REST response into a blob but I am unable to do some because
blob()
andarrayBuffer()
have not yet been implemented in the Response Object. The Response Body is a private variable.... return this.http.get(url, {params: params, headers: headers}) .map(res => { // can't access _body because it is private // no method appears to exist to get to the _body without modification new Blob([res._body], {type: res.headers.get('Content-Type')}); }) .catch(this.log); ...
Is there a solution I can use until these methods get implemented?
