Looks like you missed your auth_secret. It should be used in generating signature. Here is python example, it can be useful for you.
import time, random, hmac, urllib, httplib
from hashlib import sha1
nonce = str(random.randint(1, 10000))
timestamp = str(int(time.time()))
signature_raw_body = ("application_id=" + application_id + "&auth_key=" + auth_key +
"&nonce=" + nonce + "×tamp=" + timestamp)
signature = hmac.new(auth_secret, signature_raw_body, sha1).hexdigest()
params = urllib.urlencode({'application_id': application_id,
'auth_key': auth_key,
'timestamp': timestamp, 'nonce' : nonce,
'signature' : signature})
conn = httplib.HTTPSConnection("api.quickblox.com")
conn.request("POST", "/session", params, {})
response = conn.getresponse()
Also you can use this method for generating signature:
+ (NSString *)signData:(NSData *)data withSecret:(NSString *)secret{
NSData *secretData = [secret dataUsingEncoding:NSUTF8StringEncoding];
NSData *clearTextData = data;
uint8_t digest[CC_SHA1_DIGEST_LENGTH] = {0};
CCHmacContext hmacContext;
CCHmacInit(&hmacContext, kCCHmacAlgSHA1, secretData.bytes, secretData.length);
CCHmacUpdate(&hmacContext, clearTextData.bytes, clearTextData.length);
CCHmacFinal(&hmacContext, digest);
NSData *result = [NSData dataWithBytes:digest length:CC_SHA1_DIGEST_LENGTH];
NSString *hash = [result description];
hash = [hash stringByReplacingOccurrencesOfString:@" " withString:@""];
hash = [hash stringByReplacingOccurrencesOfString:@"<" withString:@""];
hash = [hash stringByReplacingOccurrencesOfString:@">" withString:@""];
return hash;
}
Where:
#define CC_SHA1_DIGEST_LENGTH 20
NSData *data is data from raw body using NSUTF8StringEncoding.
