OMGHTTPURLRQ 3.2.4

Vital extensions to NSURLRequest that Apple left out for some reason.

NSMutableURLRequest *rq = [OMGHTTPURLRQ GET:@"http://api.com":@{@"key": @"value"}];

// application/x-www-form-urlencoded
NSMutableURLRequest *rq = [OMGHTTPURLRQ POST:@"http://api.com":@{@"key": @"value"}];

// application/json
NSMutableURLRequest *rq = [OMGHTTPURLRQ POST:@"http://api.com" JSON:@{@"key": @"value"}];

// PUT
NSMutableURLRequest *rq = [OMGHTTPURLRQ PUT:@"http://api.com":@{@"key": @"value"}];

// DELETE
NSMutableURLRequest *rq = [OMGHTTPURLRQ DELETE:@"http://api.com":@{@"key": @"value"}];

You can then pass these to an NSURLConnection or NSURLSession.

multipart/form-data

OMG! Constructing multipart/form-data for POST requests is complicated, let us do it for you:

OMGMultipartFormData *multipartFormData = [OMGMultipartFormData new];

NSData *data1 = [NSData dataWithContentsOfFile:@"myimage1.png"];
[multipartFormData addFile:data1 parameterName:@"file1" filename:@"myimage1.png" contentType:@"image/png"];

// Ideally you would not want to re-encode the PNG, but often it is
// tricky to avoid it.
UIImage *image2 = [UIImage imageNamed:@"image2"];
NSData *data2 = UIImagePNGRepresentation(image2);
[multipartFormData addFile:data2 parameterName:@"file2" filename:@"myimage2.png" contentType:@"image/png"];

// SUPER Ideally you would not want to re-encode the JPEG as the process
// is lossy. If your image comes from the AssetLibrary you *CAN* get the
// original `NSData`. See stackoverflow.com.
UIImage *image3 = [UIImage imageNamed:@"image3"];
NSData *data3 = UIImageJPEGRepresentation(image3);
[multipartFormData addFile:data3 parameterName:@"file2" filename:@"myimage3.jpeg" contentType:@"image/jpeg"];

NSMutableURLRequest *rq = [OMGHTTPURLRQ POST:url:multipartFormData];

Now feed rq to [NSURLConnection sendSynchronousRequest:returningResponse:error:.

Configuring an NSURLSessionUploadTask

If you need to use NSURLSession’s uploadTask: but you have become frustrated because your endpoint expects a multipart/form-data POST request and NSURLSession sends the data raw, use this:

id config = [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:someID];
id session = [NSURLSession sessionWithConfiguration:config delegate:someObject delegateQueue:[NSOperationQueue new]];

OMGMultipartFormData *multipartFormData = [OMGMultipartFormData new];
[multipartFormData addFile:data parameterName:@"file" filename:nil contentType:nil];

NSURLRequest *rq = [OMGHTTPURLRQ POST:urlString:multipartFormData];

id path = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:@"upload.NSData"];
[rq.HTTPBody writeToFile:path atomically:YES];

[[session uploadTaskWithRequest:rq fromFile:[NSURL fileURLWithPath:path]] resume];

OMGUserAgent

If you just need a sensible UserAgent string for your application you can pod OMGHTTPURLRQ/UserAgent and then:

#import <OMGHTTPURLRQ/OMGUserAgent.h>

NSString *userAgent = OMGUserAgent();

OMGHTTPURLRQ adds this User-Agent to all requests it generates automatically.

So for URLRequests generated other than by OMGHTTPURLRQ you would do:

[someURLRequest addValue:OMGUserAgent() forHTTPHeaderField:@"User-Agent"];

Twitter Reverse Auth

You need an OAuth library, here we use the TDOAuth pod. You also need your API keys that registering at https://dev.twitter.com will provide you.

NSMutableURLRequest *rq = [TDOAuth URLRequestForPath:@"/oauth/request_token" POSTParameters:@{@"x_auth_mode" : @"reverse_auth"} host:@"api.twitter.com" consumerKey:APIKey consumerSecret:APISecret accessToken:nil tokenSecret:nil];
[rq addValue:OMGUserAgent() forHTTPHeaderField:@"User-Agent"];

[NSURLConnection sendAsynchronousRequest:rq queue:nil completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
    id oauth = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    SLRequest *reverseAuth = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:[NSURL URLWithString:@"https://api.twitter.com/oauth/access_token"] parameters:@{
        @"x_reverse_auth_target": APIKey,
        @"x_reverse_auth_parameters": oauth
    }];
    reverseAuth.account = account;
    [reverseAuth performRequestWithHandler:^(NSData *data, NSHTTPURLResponse *urlResponse, NSError *error) {
        id creds = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
        id credsDict = [NSMutableDictionary new];
        for (__strong id pair in [creds componentsSeparatedByString:@"&"]) {
            pair = [pair componentsSeparatedByString:@"="];
            credsDict[pair[0]] = pair[1];
        }
        NSLog(@"%@", credsDict);
    }];
}];
