I have been trying to upload UIImage on the server,but before uploading i have been converting it to BASE64 string.The method is POST and i am sending the image with other parameters in body.Have read several answers related to this but didn't get anything useful.
Here is my code
-(void)makeprofileWithData:(NSString *)urlstring andname:(NSString *)name gender:(NSString *)gender withstatus:(NSString *)status latitide:(NSString *)lat withLongitude:(NSString *)longitude andaddress:(NSString *)address andImage:(NSString *)string;
{
appdel=(AppDelegate *)[UIApplication sharedApplication].delegate;
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"%#%#",appdel.bseurl,urlstring]];
receivedData = [[NSMutableData alloc] initWithLength:0];
NSString *tempString=[NSString stringWithFormat:#"mobile=%#&name=%#&gender=%#&status=%#&address=%#&latitude=%#&longitude=%#&profile_pic=%#",[[NSUserDefaults standardUserDefaults]objectForKey:#"mobile"],name,gender,status,address,lat,longitude,string];
NSData *requestData = [tempString dataUsingEncoding:NSUTF8StringEncoding];
NSError *error;
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: requestData];
[NSURLConnection connectionWithRequest: request delegate:self];
}
In this method the string is the BASE64 string,and i am sending other parameters like mobile,name location,address ,gender also in the body separated by &.
I suggest instead of BASE64 conversion you can use GZiP Compression. It will give better result. You can download sample project from here
Here
You can use GZIP class from Compression and uncompression.
I think there may be a problem with your UTF8 encoding; can you check the result of
- (BOOL)canBeConvertedToEncoding:(NSStringEncoding)encoding
in your code to clear away that possibility.

I have an webservices url which appends with password. When I run the application by giving correct password, the application is running and at the same time when I run the app with wrong credentials. the app is running, I didn't have an idea to get rid out of the issue. My code is here:
NSString *post =[[NSString alloc] initWithFormat:#"password=%#",[password text]];
NSLog(#"PostData: %#",post);
NSURL *url=[NSURL URLWithString:[NSString stringWithFormat:#"http://myexample.com/Accountservice/Secure/ValidateAccess?password=abcd&type=1"]];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSURLRequest *request1 = [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:post] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:10];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request1 delegate:self startImmediately:YES];
if(!connection){
NSLog(#"connection failed");
}
else{
NSLog(#"connection succeeded");
}
If I gave 'abcd' as password connection is successfully is displaying. If I gave wrong password connection successfully is displaying. How can I solve the issue? If I gave wrong password need to display an alert.
This control structure here is the problem:
if(!connection){
NSLog(#"connection failed");
}
else {
NSLog(#"connection succeeded");
}
This doesn't check for a bad connection, this checks whether or not the connection object is equal to 0 (nil). Obviously, having initialized it on the line above, the else statement will always log, giving you the false impression that your connection had succeeded. You should become the connection's delegate, and respond to the appropriate delegate methods instead.
The issue may be with the url you are using
Fire the url in the browser and see what it returnes
try add the url params with single quotes accesscode='abcd'
It is not a good practice to pass the credentials via this way.
You could use POST method with some valid encryption to prevent the security issues that can occur
SOLUTION
Try this
NSString *urlString=#"http://myexample.com/Accountservice/Secure/ValidateAccess?";
self.responseData = [NSMutableData data];
NSString *post =[NSString stringWithFormat:#"username=%#&password=%#",userNameTextField.text,passwordTextField.text];
NSData *postData=[post dataUsingEncoding:NSUTF8StringEncoding];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSURLConnection *connection0= [[NSURLConnection alloc] initWithRequest:request delegate:self];
[connection0 start];
I've done many searches but none of the code fragments I find seem to work for me. I have the following fragment in xcode for running within my iPhone app:
NSURL *url = [NSURL URLWithString:#"http://blah.blah.com/rec.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
NSData *body = [#"data=crap" dataUsingEncoding:NSUTF8StringEncoding];
NSString *bodyLength = [NSString stringWithFormat:#"%d", [body length]];
[request setValue:bodyLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:body];
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:NULL error:NULL];
The rec.php is called fine but the post data does not make it through. The entry $_POST['data'] is empty. Could anyone let me know what I'm doing wrong?
I'm trying to manipulate this curl request in Objective-C:
curl -u username:password "http://www.example.com/myapi/getdata"
I've implemented the following and I'm getting a data get error Domain=kCFErrorDomainCFNetwork Code=303 with NSErrorFailingURLKey=http://www.example.com/myapi/getdata:
// Make a call to the API to pull out the categories
NSURL *url = [NSURL URLWithString:#"http://www.example.com/myapi/getdata"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
// Create the username:password string for the request
NSString *loginString = [NSString stringWithFormat:#"%#:%#", API_USERNAME, API_PASSWORD];
// Create the authorisation string from the username password string
NSData *postData = [loginString dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
[request setURL:url];
[request setHTTPMethod:#"GET"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error;
NSURLResponse *response;
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
I was hoping that someone could spot where I am going wrong with my attempt to manipulate the curl request and point me in the correct direction. Is there something obvious I'm missing out? The data returned from the API is in a JSON format.
I found that the best thing to do was to not attempt the authentication within the code and to put it straight in the URL itself. The working code looks as follows:
NSURL *url = [NSURL URLWithString: [NSString stringWithFormat:#"http://%#:%##www.example.com/myapi/getdata", API_USERNAME, API_PASSWORD]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setURL:url];
[request setHTTPMethod:#"GET"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
NSError *error;
NSURLResponse *response;
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
This guide seems to do what you're looking for:

Just as an FYI, a lot of classes accept initWithData, and NSData has a method dataWithContentsOfURL, if you want to avoid setting up NSURLConnections yourself this could be an easier way of achieving what you're looking for.

I make iphone application, post parametes to JSP (test.jsp in server) from iphone. The following is my codes:
NSData *postData = [#"&test=123&field=456" dataUsingEncoding:NSUTF8StringEncoding];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
// Init and set fields of the URLRequest
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:#"POST"];
[request setURL:[NSURL URLWithString:[NSString stringWithString:#"http://mydomain.com/test.jsp"]]];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:postData];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (connection) {
// Return data of the request
NSData *receivedData = [[NSMutableData data] retain];
}
[request release];
But my problem is: I can not get return result from JSP server.
How I can setup in JSP to get return result in iPhone? and in iPhone too?
Thank all
Do you implement this in your delegate:
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
Data won't just magically appear in your receivedData instance. You need to implement the delegate methods for NSURLConnection. Take a look at Apple's documentation on how to this all properly.
