Hebrew as Gibberish on the server side
Question
I have an iPhone simulator app as client and WCF-REST, json encoded service running on IIS 7.0 server. I'm trying to send some hebrew characters to the service as parameter and the server return error code 400 - Bad Request. When I'm sending an English string the server processes the string as it should.
The code used for the string encoding looks like this:
Note that "parameters" is the parameters that about to be sent to the server, ordered as parameter_name => parameter_value.
//RPC JSON
NSString* reqString = [parameters JSONRepresentation];
//Request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
NSData* requestData = [NSData dataWithBytes:[reqString UTF8String] length:[reqString length]];
//prepare http body
[request setHTTPMethod: @"POST"];
[request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json; charset=UTF-8" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody: requestData];
urlConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];
The request and response I'm getting in the server side (got this by using ethereal):
Request:

I had an error on the posted code.
NSData* requestData = [NSData dataWithBytes:[reqString UTF8String] length:[reqString length]];
This line (was originally in the question's code) generated the error - instead of taking the length of the bytes array returned from: "[reqString UTF8String]", a wrong length had been given - the length of the nsstring...
The fixed code:
const char *utf8String = [reqString UTF8String]; // no need to free me - autoreleased object returned.
NSInteger l = strlen(utf8String);
NSData *requestData = [NSData dataWithBytes:utf8String length:l];
