Question

I’m having a difficulty transforming this curl command for my Objective C Code:

curl -u 0ef106c78146a23becba9105d1e:X -H "Accept: application/json" -H "Content-Type: application/json" https://boomboom.c27.imonggo.com/api/products.json

Here’s my objective C code:

NSError *theError = NULL;
NSURL *theURL = [NSURL URLWithString:@"https://boomboom.c2.imonggo.com/api/products.json"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:theURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10.0f];
[theRequest setValue:@"0ef106c78146a23becba9105d1e" forHTTPHeaderField:@"username"];
[theRequest setValue:@"x" forHTTPHeaderField:@"password"];
[theRequest setValue:@"application/json" forHTTPHeaderField:@"Accept:"];
[theRequest setValue:@"application/json" forHTTPHeaderField:@"Content-Type:"];


NSURLResponse *theResponse = NULL;
NSData *theResponseData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:&theResponse error:&theError];

Most likely my problem is with the header fields.

Answer 1

First of all, you don’t need the colon in the HTTP header field name.

Second, you’re doing the HTTP authentication wrong. You need to concat your username and password, username:password and Base64 encode the concatenated string data.
Use the base64 value as value for the header field Authorization, use the code below and drop in a Base 64 encoding implementation.

    // snip
    NSMutableUrlRequest* theRequest = [NSMutableUrlRequest ...]
    [MyClass httpAuthorizeRequest:theRequest withUsername:@"someuser" andPassword:@"mysecret"];
    // snip

+ (void)httpAuthorizeRequest:(NSMutableURLRequest*)request withUsername:(NSString*)username andPassword:(NSString*)password
{
    NSString* authorizationToken = [[NSString stringWithFormat:@"%@:%@", username, password] base64Representation];
    [request setValue:[NSString stringWithFormat:@"Basic %@", authorizationToken] forHTTPHeaderField:@"Authorization"];
}
