FetchBackend expects case sensitive 'Content-Type' #56539
Description
Which @angular/* package(s) are the source of the bug?
platform-browser
Is this a regression?
Yes
Description
The snippet below creates a request with header content-type: image/jpeg, application/json
let headers = new HttpHeaders();
headers = headers.set('content-type', 'image/jpeg');
const req = new HttpRequest("PUT", somePutUrl, { data: someData }, {
headers,
reportProgress: true,
responseType: "text",
});
return this.client.request(req);Change the case and I get the expected behaviour:
let headers = new HttpHeaders();
headers = headers.set('Content-Type', 'image/jpeg');
const req = new HttpRequest("PUT", somePutUrl, { data: someData }, {
headers,
reportProgress: true,
responseType: "text",
});
return this.client.request(req);Please provide a link to a minimal reproduction of the bug
