Match request body using block

[brow]

Request bodies are most often encoded as application/json, application/x-www-form-urlencoded, or application/xml. Each of those encodings can represent the same data in more than one way.

For example, in JSON encoding, {"a":1, "b":2} is equivalent to {"b":2, "a":1}. In fact, some JSON serializers behave nondeterministically as to which of those two they emit.

Therefore, it usually doesn't make sense to test the body of a request using -[NSData equals]. Instead, you want to use a notion of equality appropriate to the encoding.

This pull enables matching a request body using an arbitrary block, like so:

stubRequest(@"POST", @"https://api.example.com/endpoint.json").
withHeaders(@{@"Accept": @"application/json"}).
withBodyWhere(^(NSData *body){
    id bodyJSONObject = [NSJSONSerialization JSONObjectWithData:body
                                                        options:0
                                                          error:NULL];
    return [bodyJSONObject isEqual:@{@"a": @1, @"b": @2}];
});

👍 This would be very helpful!

This is awesome. It would be great to do the same thing for the path also,

http://service.com?a=1&b=2 == http://service.com?b=2&a=1
