change how AFJSONRequestSerializer encodes JSON

Question

I am using AFNetworking. The AFHTTPRequestOperationManager requestSerializer is set to use AFJSONRequestSerializer.

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager] manager.requestSerializer = [AFJSONRequestSerializer serializer];

HTTP Body with current setup: {"key" : "http:\/\/myURL.com\/}

Desired HTTP Body: {"key" : "http://myURL.com/}

How can I prevent / from being escaped with \?

cast the string to `NSString` and use `removingPercentEncoding`. — Ryan, Apr 18 '18 at 20:57

There is a very, very high chance that you are confusing what _is_ in a string with what some tool displays. And if the body is supposed to be JSON, then both bodies are absolutely equivalent as JSON. If your server interprets them in different ways, then your server code is broken. — gnasher729, Apr 21 '18 at 16:25
@gnasher729 You are correct, the server code is broken and the reason for this question. Unfortunately it is not fixable at this time. — Thomas R, Apr 25 '18 at 19:17

In order to resolve this issue I subclassed AFJSONRequestSerializer and overrode requestBySerializingRequest:withParameters:error:

- (NSURLRequest *)requestBySerializingRequest:(NSURLRequest *)request withParameters:(nullable id)parameters error:(NSError *__autoreleasing  _Nullable * _Nullable)error {
    NSURLRequest *myRequest = [super requestBySerializingRequest:request withParameters:parameters error:error];

    NSData *jsonData = myRequest.HTTPBody;

    if (jsonData) {
        NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

        if (jsonString) {
            NSString *sanitizedString = [jsonString stringByReplacingOccurrencesOfString:@"\\/" withString:@"/" options: NSCaseInsensitiveSearch range: NSMakeRange(0, [jsonString length])];
            NSMutableURLRequest *mutableRequest = [myRequest mutableCopy];
            mutableRequest.HTTPBody = [sanitizedString dataUsingEncoding:NSUTF8StringEncoding];
            myRequest = mutableRequest;
        }
    }

    return myRequest;
}
