I'm setting a asynchronous post request with a document, containing hundreds of location points. I want to save this document in my couchdb.
For small documents, the request response returns in very short time, storing the document. When the document grows a bit more (still < ~200k) the response takes ages and then it returns with a timeout. I set the timeout for 120 seconds.
Am I missing some setting or doing an coding error?
- (void)post:(NSData*) requestBody {
startTime = [NSDate date];
NSURL* serverURL = [NSURL URLWithString: @"https://myUser:myPassword@myAcc.cloudant.com/myDB"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:serverURL];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setHTTPMethod:@"POST"];
[request setTimeoutInterval:120.0];
[request setHTTPBody:requestBody];
[NSURLConnection sendAsynchronousRequest:request queue:[[NSOperationQueue alloc] init] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error)
{
if (response != nil) {
if ([response respondsToSelector:@selector(statusCode)])
{
int statusCode = [((NSHTTPURLResponse *)response) statusCode];
NSLog(@"StatusCode returned was %i", statusCode);
}
NSLog(@"Response: %@",response);
}
if ([data length] >0 && error == nil)
{
NSLog(@"data: %@", data);
// DO YOUR WORK HERE
}
else if ([data length] == 0 && error == nil)
{
NSLog(@"Nothing was downloaded.");
}
else if (error != nil){
NSLog(@"Error = %@", error);
}
}];
EDIT: the problem with the timeout still remains. I logged in the progress in the didSendBodyData: and recognized, that bytes were sent. Not all, then the timeout occurs. With curl, the upload works just fine.
Additionally I recognized one thing in the log: When the request was successful, total and expected bytes were the same:
Total Bytes written: 161120
Expected Bytes to write: 161120
When the request failed:
Total Bytes written: 163840
Expected Bytes to write: 166839
Any other ideas?
