I have an API that expects a JWT token.
I tested the API with https://hoppscotch.io, here is the query that returns the expected results (no error)
import axios from "axios";
const options = {
method: 'POST',
url: 'https://my_authority/text-message',
headers: {
Authorization: 'Bearer my_token',
'content-type': 'application/json'
},
data: {message: ''}
};
axios.request(options).then(function (response) {
console.log(response.data);
}).catch(function (error) {
console.error(error);
});
And here is the code in Dart that fires the error ClientException (Failed to parse header value):
await http.post(
Uri.parse('$_httpEndpoint/$path'),
headers: {
HttpHeaders.contentTypeHeader: 'application/json',
HttpHeaders.authorizationHeader: 'Bearer my_token',
},
body: jsonEncode(body));
Both queries have the same parameters. I have no clue about the root causes.
Here is requests.headers in locals for IOClient.send when the error fires:
_CompactLinkedCustomHashMap ({content-type: application/json; charset=utf-8, authorization: Bearer my_token})
I don't know why http adds charset=utf-8, and I didn't manage to remove it.
I looked over the internet and didn't find an answer. Most of the similar questions are related to an error in the backend, it is not the case here.
My workflow's script with action/github-script(v6) step:
const response = await github.request('POST https://example.com', {
headers: {
authorization: 'Bearer xxx',
accept: 'application/vnd.heroku+json; version=3', // I want header to be like this
'content-type': 'application/json'
},
// some other options, like request body...
});
console.log(response);
When the accept and other HTTP headers are automatically overriden with:
{
status: 400,
reponse: {}, // not important, body complains about incorrect Accept header
request: {
method: 'POST',
url: 'example.com',
headers: {
accept: 'application/vnd.github.-preview+json', // wtf?
authorization: 'token [REDACTED]', // wtf? it should start with "Bearer"
'content-type': 'application/json', // ok, as expected
'user-agent': 'actions/github-script octokit-core.js/3.5.1 Node.js/16.13.0 (linux; x64)' // ok, but I didn't set this...
},
// other stuff...
}
Now the question is what am I missing? Can I make truthly custom request using github.request() api like that?
I am using axios#0.21.1 and I want to validate the response headers.
I am unable validate the headers "Content-Type" and "Content-Encoding" from a GET response.
"Content-Type": No matter what content-type i pass in request, the content-type in response is always application/JSON.
Example Code Snippet:
if (<token is present>) {
request.headers = {
authorization : 'Bearer ${token}'
}
} else {
config.auth = {}
}
config.headers = Object.assign(config.header, {
'content-type': application/<custom content>,
'accept-encoding': 'gzip, deflate, br'
}
await axios.get(endPoint, config)
.then(response => {
return response
}*
When i am checking response.header, i see that content-type is showing as "application/json" instead of the custom type. But when i hit the same url in POSTMAN i could see that content-type is as expected.
Content-Encoding: I want to validate the content-encoding in the response, but what i learnt is axios does not return content-encoding header in the response and when i check their github, they are asking to use axios.interceptors. I tried using interceptors but still i am not seeing the header in response. But this header is present in response when i try in POSTMAN. There have been some solution say CORS needs to be enabled in server side. I am strictly asking it from QA point of view because we cannot enable CORS in server side.
Any help is highly appreciable.
Try:
axios.post(your-url, {
headers: {
'Content-Encoding': 'gzip'
}
})
or
axios.post(your-url, {
headers: {
'Accept-Encoding': 'gzip',
}
})
This is by design: https://axios-http.com/docs/req_config
I also ran into this and couldn't find a solution. Ended up using node-fetch instead.
How do you add headers to your http request in Angular2 RC6?
I got following code:
login(login: String, password: String): Observable<boolean> {
console.log(login);
console.log(password);
this.cookieService.removeAll();
let headers = new Headers();
headers.append("Authorization","Basic YW5ndWxhci13YXJlaG91c2Utc2VydmljZXM6MTIzNDU2");
this.http.post(AUTHENTICATION_ENDPOINT + "?grant_type=password&scope=trust&username=" + login + "&password=" + password, null, {headers: headers}).subscribe(response => {
console.log(response);
});
//some return
}
The problem is, that angular doesn't add Authorization header. Instead of that, in request I can see following additional headers:
Access-Control-Request-Headers:authorization
Access-Control-Request-Method:POST
and sdch added in Accept-Encoding:
Accept-Encoding:gzip, deflate, sdch
Unfornately there is no Authorization header. How should I add it correctly?
Whole request sent by my code looks as follow:
OPTIONS /oauth/token?grant_type=password&scope=trust&username=asdf&password=asdf HTTP/1.1
Host: localhost:8080
Connection: keep-alive
Pragma: no-cache
Cache-Control: no-cache
Access-Control-Request-Method: POST
Origin: http://localhost:3002
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36
Access-Control-Request-Headers: authorization
Accept: */*
Referer: http://localhost:3002/login
Accept-Encoding: gzip, deflate, sdch
Accept-Language: en-US,en;q=0.8,pl;q=0.6
Ok. I found problem.
It was not on the Angular side. To be honest, there were no problem at all.
Reason why I was unable to perform my request succesfuly was that my server app was not properly handling OPTIONS request.
Why OPTIONS, not POST? My server app is on different host, then frontend. Because of CORS my browser was converting POST to OPTION:
http://restlet.com/blog/2015/12/15/understanding-and-using-cors/
With help of this answer:
Standalone Spring OAuth2 JWT Authorization Server + CORS
I implemented proper filter on my server-side app.
Thanks to #Supamiu - the person which fingered me that I am not sending POST at all.
you need RequestOptions
let headers = new Headers({'Content-Type': 'application/json'});
headers.append('Authorization','Bearer ')
let options = new RequestOptions({headers: headers});
return this.http.post(APIname,body,options)
.map(this.extractData)
.catch(this.handleError);

I believe you need to map the result before you subscribe to it. You configure it like this:
updateProfileInformation(user: User) {
var headers = new Headers();
headers.append('Content-Type', this.constants.jsonContentType);
var t = localStorage.getItem("accessToken");
headers.append("Authorization", "Bearer " + t;
var body = JSON.stringify(user);
return this.http.post(this.constants.userUrl + "UpdateUser", body, { headers: headers })
.map((response: Response) => {
var result = response.json();
return result;
})
.catch(this.handleError)
.subscribe(
status => this.statusMessage = status,
error => this.errorMessage = error,
() => this.completeUpdateUser()
);
}
If you are like me, and starring at your angular/ionic typescript, which looks like..
getPdf(endpoint: string): Observable<Blob> {
let url = this.url + '/' + endpoint;
let token = this.msal.accessToken;
console.log(token);
return this.http.post<Blob>(url, {
headers: new HttpHeaders(
{
'Access-Control-Allow-Origin': 'https://localhost:5100',
'Access-Control-Allow-Methods': 'POST',
'Content-Type': 'application/pdf',
'Authorization': 'Bearer ' + token,
'Accept': '*/*',
}),
//responseType: ResponseContentType.Blob,
});
}
And while you are setting options but can't seem to figure why they aren't anywhere..
Well.. if you were like me and started this post from a copy/paste of a get, then...
Change to:
getPdf(endpoint: string): Observable<Blob> {
let url = this.url + '/' + endpoint;
let token = this.msal.accessToken;
console.log(token);
return this.http.post<Blob>(url, null, { // <----- notice the null *****
headers: new HttpHeaders(
{
'Authorization': 'Bearer ' + token,
'Accept': '*/*',
}),
//responseType: ResponseContentType.Blob,
});
}
I had the same issue. This is my solution using angular documentation and firebase Token:
getService() {
const accessToken=this.afAuth.auth.currentUser.getToken().then(res=>{
const httpOptions = {
headers: new HttpHeaders({
'Content-Type': 'application/json',
'Authorization': res
})
};
return this.http.get('Url',httpOptions)
.subscribe(res => console.log(res));
}); }}
Here is the detailed answer to the question:
Pass data into the HTTP header from the Angular side (Please note I am
using Angular4.0+ in the application).
There is more than one way we can pass data into the headers.
The syntax is different but all means the same.
// Option 1
const httpOptions = {
headers: new HttpHeaders({
'Authorization': 'my-auth-token',
'ID': emp.UserID,
})
};
// Option 2
let httpHeaders = new HttpHeaders();
httpHeaders = httpHeaders.append('Authorization', 'my-auth-token');
httpHeaders = httpHeaders.append('ID', '001');
httpHeaders.set('Content-Type', 'application/json');
let options = {headers:httpHeaders};
// Option 1
return this.http.post(this.url + 'testMethod', body,httpOptions)
// Option 2
return this.http.post(this.url + 'testMethod', body,options)
In the call you can find the field passed as a header as shown in the image below :
Still, if you are facing the issues like.. (You may need to change the backend/WebAPI side)
Response to preflight request doesn't pass access control check: No
''Access-Control-Allow-Origin'' header is present on the requested resource. Origin ''http://localhost:4200'' is therefore not allowed
access
Response for preflight does not have HTTP ok status.

if you are a ruby on rails developer and you facing a similar issue, this is because of the config of your backend: especially in api mode
so with
gem 'rack-cors' installed
goto app/config/cors.rb
Be sure to restart your server when you modify this file.
Rails.application.config.middleware.insert_before 0, Rack::Cors do
allow do
origins 'domain_name:port or just use *'
resource '*',
headers: :any,
methods: [:get, :post, :put, :patch, :delete, :options, :head],
credentials: true
end
end
the *credentials:true line does the trick
then in your SessionController
after a user is valid for login
insert a line(this assumes you are using gem 'jwt')
token = user.generate_jwt
response.headers['Authorization'] = token
generate_jwt is a method called in model User , it is
JWT.encode(id, key, alogrithm)
If you use django, that is already taken care for you
you just have to use
installed app: restframework_simplejwt
Using the wslite.rest.RestClient, if I use post or put, I'm getting a 411 Length Required error returned from the service. I've added the header Content-Length: (size) but I still get an error. Does anyone have suguestions? Here's the code for a put request:
def builder = new JsonBuilder()
// required json data
def root = builder {
"ActivationDate" "\\/Date(1434563608000-0500)\\/"
"EmailAddress" "ebaa#gmail.com"
"ExpirationDate" "\\/Date(1435686808000-0500)\\/"
"FirstName" "ebaa"
"LastName" "ebaa"
"MiddleName" "ebaa"
"OtherName" "ebaa"
"Password" "abc12345"
"Status" 1
}
RESTClient restClient = new RESTClient('https://serviceBaseUrl')
Response response
try {
restClient.authorization = new HTTPBasicAuthorization(username: 'user', password: 'pass')
restClient.defaultCharset = 'UTF-8'
restClient.defaultContentTypeHeader = 'application/json'
restClient.defaultAcceptHeader = 'application/json'
response = restClient.put(path: "/Location/${locName}/Administrator/${name}",
headers:['Accept': 'application/json',
'Accept-Language':'en-US,en;q=0.5', 'Content-Type': 'application/json; charset=UTF-8',
'Connection':'keep-alive', 'Pragma':'no-cache', 'Cache-Control':'no-cache',
'Content-Length': builder.toString().length()],
data: builder.toPrettyString().getBytes())
return response.json
} catch(ex) {
ex.printStackTrace()
}
I've also tried changing the data: param to body, but I get the same response. Also, If I use the Firefox plugin, HttpRequester (https://addons.mozilla.org/En-us/firefox/addon/httprequester/) and make the same request, I get a 200 status code and the appropriate data is updated. Thanks!
For put or post it is expecting the payload to be in a closure. Try the following, this should send the data and automatically set the right Content-Length:
....
....
response = restClient.put(
path: "/Location/${locName}/Administrator/${name}",
headers:['Accept': 'application/json',
'Accept-Language':'en-US,en;q=0.5',
'Content-Type': 'application/json; charset=UTF-8',
'Connection':'keep-alive',
'Pragma':'no-cache',
'Cache-Control':'no-cache'])
{
text builder.toPrettyString()
//bytes builder.toPrettyString().bytes // or as bytes
//json 'ActivationDate': '...', 'EmailAddress': '...' // or a json string from a map
}
