SDWebImage and setting custom HTTP headers? - uiimageview

Question

I´ve just changed my code for caching images away from EGOImageCache to SDWebView. Unfortunately i don´t know how to set custom HTTP headers as i have to send authentification to be able to fetch images. It was easy done with EGOImageCache as i´ve extended the NSURLRequest at the appropriate place. But i don´t know how to do that with the SDWebView.framework. I see the headers and i´ve found methods in SDWebImageDownloader.h containing
/**
* Set a value for a HTTP header to be appended to each download HTTP request.
*
* #param value The value for the header field. Use `nil` value to remove the header.
* #param field The name of the header field to set.
*/
- (void)setValue:(NSString *)value forHTTPHeaderField:(NSString *)field;
/**
* Returns the value of the specified HTTP header field.
*
* #return The value associated with the header field field, or `nil` if there is no corresponding header field.
*/
- (NSString *)valueForHTTPHeaderField:(NSString *)field;
It seems that the lib does support HTTP headers. But as i use UIImageView+WebCache.h i can´t see there an option for setting the headers. In my code i call
[self.imageView setImageWithURL:[NSURL URLWithString:themeImageURL] placeholderImage:[UIImage imageNamed:#"placeholder.png"]];
Can anybody tell me how to set HTTP headers?

Answer 1

I had the same problem, and I tried to make:
SDWebImageDownloader *manager = [SDWebImageDownloader sharedDownloader];
[manager setValue:username forHTTPHeaderField:#"X-Oauth-Username"];
But the header were not send. After some tries, I came across the problem, SDWebImageDownloader at sharedDownloader makes a new instance of SDWebImageDownloader, so when you put the header at that instance, the instance that really downloads the image don't has the header.
I've solved making this:
SDWebImageDownloader *manager = [SDWebImageManager sharedManager].imageDownloader;
[manager setValue:username forHTTPHeaderField:#"X-Oauth-Username"];

Swift Version
let imageDownloader = SDWebImageDownloader.shared()
imageDownloader.setValue("Username", forHTTPHeaderField: "X-Oauth-Username")

Answer 3

I know it's pretty old but couldn't help to share what worked for me. I needed to set a login token value for header logintoken. So, this piece of code did what I wanted -
NSString *loginToken = // Some method to fetch login token
[SDWebImageDownloader.sharedDownloader setValue:loginToken forHTTPHeaderField:#"logintoken"];

Answer 4

I am using Basic authentication and setting the username and password on the sharedDownloader helped:
SDWebImageDownloader *downloader = [SDWebImageDownloader sharedDownloader];
downloader.username = #"username";
downloader.password = #"password";

Swift 4.1
let manager = SDWebImageManager.shared().imageDownloader
manager?.setValue("oAuthToken",forHTTPHeaderField: "AuthHeaderName")
manager?.downloadImage(with: imageURL, options: SDWebImageDownloaderOptions.useNSURLCache, progress:
{ (receivedSize, expectedSize , url) in
// progression tracking code
}, completed: { (image,data , error,finished) in
if error == nil && image != nil {
// here the downloaded image is cached, now you need to set it to the imageView
DispatchQueue.main.async {
imageView.image = image
self.maskCircle(anyImage: image!)
}
} else {
// handle the failure
DispatchQueue.main.async {
let defaultImage = UIImage(named: "defaultImage")
imageView.image = defImage
self.maskCircle(anyImage: defImage)
}
}
})
