How to add string field to NSURLRequest header field?

Question

I am very upset to figure out how to add a lowercase header field to NSMutableURLRequest.

NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:MyURLString]];
[urlRequest setValue:@"aValue" forHTTPHeaderField:@"field"];

In the above example, the "field" switches to "Field" because the header field names are not case sensitive. I would think that this should not be, but it is. The API I'm working with is case sensitive, so my GET request is ignored. Is there a way to override the case switch?

Answer 1

HTTP header fields must be case insensitive , so you need to fix your API.

Answer 2

: - [NSMutableURLRequest setValue: forHTTPHeaderField:] . , .

Answer 3

Is it possible to try with addValue (_: forHTTPHeaderField :)?

NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:
[NSURL URLWithString:MyURLString]];
[urlRequest addValue:@"aValue" forHTTPHeaderField:@"field"];
