angular 5 httpclient , on post , the response does not return custom headers, only returns response object












1














I'm not getting the actual http headers when making the http post call using Angular 5 common httpClient. I'm passing observe: 'response' in request to get the full response (by default httpClient returns only the body in response).



I want to read the csrftoken value from http header response. I can see that csrftoken is available in response headers using chrome browser network view.



But the same is not available when I read the httpClient response in Angular.



 post(inURL, data, config = undefined) {
let headers, options;
if (config){
options = config;
} else {
//headers = this.getDefaultHeader();
//options = new RequestOptions({ headers: headers });
options = httpOptions;
}
options = { ...options, observe: 'response' };

let action = this.httpService.post(inURL, data, options);
return new Promise((resolve, reject) => {
action.subscribe(
response => resolve(response),
error => {
this.interceptError(error);
reject(error);
}
);
});


    }
enter image description here



and the response headers object looks like this while debugging on chrome debugger, as you see the csrftoken is not available as a key on the response object



enter image description here



Here is what i have for accessing the httpheaders



   let headers: HttpHeaders = response.headers;
if (headers && headers['csrftoken']) {
let token: String = headers.get('csrftoken');
}

  • Have you at least tried to get the token out of the HttpHeaders object? Show that code.

    Here's the documentation of HttpHeaders: angular.io/api/common/http/HttpHeaders. It's not a POJO. Use headers.has('csrftoken').

As already suggested in the comments you cannot check if a header exists the way you are doing it. You need to use the has method. Your code should look like this:



let headers: HttpHeaders = response.headers;
if (headers && headers.has('csrftoken')) {
let token: String = headers.get('csrftoken');
}
