iOS: Support HTTP headers for source prop on <Image> components #7338

rigdern · 2016-05-02T22:52:19Z

Allows developers to specify headers to include in the HTTP request
when fetching a remote image. For example, one might leverage this
when fetching an image from an endpoint that requires authentication:

<Image
  style={styles.logo}
  source={{
    uri: 'http://facebook.github.io/react/img/logo_og.png',
    headers: {
      Authorization: 'someAuthToken'
    }
  }}
/>

Note that the header values must be strings.

Works on iOS and Android.

Test plan (required)

Ran a small example like the one above on iOS and Android and ensured the headers were sent to the server.
Ran a small example to ensure that components without headers still work.
Currently using this code in our app.

 CGSize size = CGSizeZero;

Just check if (!headers)

@rigdern You're awesome for submitting both Android and iOS implementations that both look good at a glance. Would like to get more reviewers on the code, but this PR looks promising.

nicklockwood · 2016-05-26T09:41:23Z

@rigdern This is a good idea, but changing these iOS APIs will break quite a lot of our stuff internally.

I think the better approach here would be to add a new method to RCTImageLoader that takes an NSURLRequest, which we already have an RCTConvert method for processing in a standard format (it's already used by WebView.source). Validating that the headers are all strings should also be done inside RCTConvert (though it isn't currently).

The existing methods of RCTImageLoader can then be refactored to call the new method, so we don't break anything, and we can deprecate the old methods.

Also, while I echo @ide's sentiment about building both iOS and Android implementations, it's much easier for us to merge if it's split into separate PRs for each platform.

Allows developers to specify headers to include in the HTTP request when fetching a remote image. For example, one might leverage this when fetching an image from an endpoint that requires authentication: ``` <Image style={styles.logo} source={{ uri: 'http://facebook.github.io/react/img/logo_og.png', headers: { Authorization: 'someAuthToken' } }} /> ``` Note that the header values must be strings. When doing image requests, this also gives developers control over the other properties supported by [RCTConvert NSURLRequest:] like `method` and `body`. This change deprecates some APIs on RCTImageLoader in order to replace them with more flexible APIs which take an NSURLRequest rather than just an NSURL.

rigdern · 2016-05-27T00:27:10Z

@nicklockwood As you suggested, I created several new RCTImageLoader methods which accept an NSURLRequest and deprecated the old ones which accepted an NSURL. I also removed the Android implementation of the feature and will submit it in a separate PR.

@rigdern - Did this PR get accepted and, if so, which version of RN did it first appear in?

EDIT -- nevermind... I see it was accepted.

Are there any working examples? This is not working for me and I am not sure how to debug this..

@IlyaRepo You want to do something like this, which is working for me

<Image 
     source={{
      uri: url,
      headers: {
         'Authorization': someToken, // or whatever your header looks like
      }
