ImageSource in Image doesn't send headers

[ash-williams]

Description

According to the docs, the ImageSource prop in the Image component should allow for sending headers like this:

<Image
    source={{uri: "http://myimage.com", headers: {"Authorization":token}}}
/>

However, the headers aren't sent in any request.

Version

Steps to reproduce

1. Create a project (I've been using Expo but don't see how that would be an issue)
2. Import image from 'react-native'
3. Try sending any header e.g.: <Image source={{ uri: "url to any image", headers: { "Content-Type": "image/jpeg", "X-Authorization": "thisismyauthtoken" } }} />
4. Inspect the HTTP request, no headers are sent (I'm running in browser and using Chrome dev tools to inspect HTTP)

I am experiencing the exact same problem.

Any solution here guys? I'm facing the same problem. The header in Image acting really weird on Android, but on IOS everything is still smooth

[ash-williams]

I was teaching a University unit when I posted the issue. The workaround we had to go with was to send a regular GET request with the headers to get the image, convert the response to a base64 string, and then use that string as the source to the Image component.

It works fine as a solution, but this issue is still valid as the component doesnt work as the documentation says it should.

Thank you. Seems like it's a well-known bug, I found another topic of this on 2019 (https://github.com/facebook/react-native/issues/25945).

Is there any progress on this one? It's a bit of a painful blocker unless we send auth material via query string...

[NilsBaumgartner1994]

Please fix this

[Youness-ben]

Is this still not fixed or are we missing somthing ? the exact same thing is happening to me.

[lunaleaps]

Thanks for reporting! Is there anyway we can narrow this bug -- is there a particular platform this is happening on?

[raarts]

I experienced it on iOS, but I think the original bug poster provided enough information.

[blazejczyk]

I can confirm the headers are still not sent. Here's how I solved this in my app (I used Avatar component from the UI Kitten library but it's actually a small wrapper for the native Image so it's the same situation).

import { useState, useCallback, useEffect } from 'react';
import { ImageSourcePropType } from 'react-native/Libraries/Image/Image';
import { Avatar } from '@ui-kitten/components';
import { EvaSize } from '@ui-kitten/components/devsupport';

import { authorizationHeaders } from '../services/apiSvc';

type TPhotoProps = {
  src: string;
  size?: EvaSize;
};

export default function Photo({ src, size }: TPhotoProps) {
  const [source, setSource] = useState<ImageSourcePropType | undefined>(undefined);

  const load = useCallback(async () => {
    try {
      const response = await fetch(src, { headers: authorizationHeaders });
      const blob = await response.blob();
      const reader = new FileReader();
      reader.readAsDataURL(blob);
      reader.onloadend = () => setSource({ uri: reader.result as string });
    } catch (err) {
      // file loading failed
      setSource(require('../../assets/images/fallback-avatar.png'));
    }
  }, [src]);

  useEffect(() => {
    load();
  }, [load]);

  return (
    <Avatar source={source} size={size} />
  );
}

Happens to me on ios if newArch is on, haven't check Android. And it's clearly not implemented: https://github.com/facebook/react-native/blob/main/packages/react-native/ReactCommon/react/renderer/imagemanager/platform/ios/react/renderer/imagemanager/RCTImagePrimitivesConversions.h#L110 That todo's been there for 6 years now. Works if disable newArch.

+1 on iOS with new arch

This basic feature is very useful to handle authenticated images, much efficient then building a base64 URL, especially in list views. Please consider adding it, it seems like a quick win.

[NilsBaumgartner1994]

Also from a security aspect this is important because some websites allow to sent the authentication in the url as „?bearer=…“. When doing this and saving the image the token gets saved too as file name.

the adding of headers is therefore essential

[Martin2037]

same issue

[Octaney]

Same here on Android. It worked for me in version 0.68.2, but after upgrading to 0.73.4 all the images disappeared! I quickly need to update the app in the stores, because of new regulations... help! :(

Update: If you are using Expo, there is a package called "expo-image", that works with headers. For non Expo users, you could try "react-native-fast-image".

[rabbitmouse]

Has this bug been fixed? I have an issue with the image in this link https://github.com/WalletConnect/web3modal-react-native/issues/137#issuecomment-1952502108

In the new architecture, when using modal, the components in the modal will flash first and then appear.

[ben-snaize-fg]

After a fix for this too. Our UAT env's are closed behind headers, so we can't get images working properly in some cases.

[0xBlitzmachine]

Same issue over here .. header is just not working. For those who still come here and read this: Use Expo's Image Component for now .. it is the same component almost and the header works there if youre lazy converting the image to base64.

[nghieptd]

I had this issue when upgrading from 0.67.5 to 0.74.4. I found out that if we have this line: Fresco.initialize(this) then it might cause double initialization (the warning about it pops up in the logcat), which somehow override the React Native image fetcher implementation in React Native library (the second parameter in the line, which we left it null). So if someone has this issue, check if the line is in MainApplication.java and try comment it out to see if it works

[PiotrBorowski]

Issue still persist in react-native 0.74.3 :/

[mateoguzmana]

I'm trying to reproduce this and haven't been able to. In Android and iOS, inspecting the network requests when loading the image, seems to pass fine the headers.

Here’s an example on Android and iOS showing the headers being passed as expected:

Android and iOS network image request passing the headers correctly

```tsx ``` **Android:** **iOS:** 

Can anyone else confirm if they’re seeing the same? I’m wondering if this issue could be related to caching: when the image is already cached on disk, for instance, it won’t make a new network request, so any new headers added wouldn’t apply.

[matheusbras]

@mateoguzmana I'm seeing the same issue on 0.76.2. No headers are being sent at all.
