Posting request to .NET server is not working.
NSDictionary *jsonDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
NSURL *postURL = [NSURL URLWithString: #"SOME URL"];
NSError *error=nil;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:jsonDict options:0 error:&error];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: postURL
cachePolicy: NSURLRequestUseProtocolCachePolicy
timeoutInterval: 60.0];
[request setHTTPMethod: #"POST"];
[request setValue: #"application/json" forHTTPHeaderField: #"Accept"];
[request setValue: #"application/json" forHTTPHeaderField: #"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d",[jsonData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: jsonData];
NSLog(#"JSON summary: %#", [[NSString alloc] initWithData:jsonData
encoding:NSUTF8StringEncoding]);
The Output is:
{"CreatedBy":"","EmailAddress":"devanrajupericherl#gmail.com","Zipcode":"","FirstName":"devan","DeviceCategoryID:":"","State":"","CustomerTypeID:":"",..........} like this.....
But it Json object must be:
({CreatedBy:"",EmailAddress:"devanrajupericherl#gmail.com",Zipcode:"",FirstName:"devan",DeviceCategoryID::"",State:"",CustomerTypeID:"" })
I am using .Net server for Posting.
Request is not Posting to the Server. Anyone please help me.

You can use the CoreGraphics' method UIImagePNGRepresentation(UIImage *image), which returns NSData and save it. and if you want to convert it into again UIImage create it using [UIimage imageWithData:(NSData *data)] method. Some Questions related to this post image to server in iphone and
How to convert image into binary format in iOS? as giving the same answer 3 time.
- (void)sendImageToServer {
UIImage *yourImage= [UIImage imageNamed:#"image.png"];
NSData *imageData = UIImagePNGRepresentation(yourImage);
NSString *postLength = [NSString stringWithFormat:#"%d", [imageData length]];
// Init the URLRequest
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:#"POST"];

Use this code to upload any image to the server. This works for me. :)
UIImage *yourImage= [UIImage imageNamed:#"image.png"];
NSData *imageData = UIImagePNGRepresentation(yourImage);
NSString *postLength = [NSString stringWithFormat:#"%d", [imageData length]];
// Init the URLRequest
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];

[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:imageData];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (connection) {
// response data of the request
}
Try this

[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:30];
[request setHTTPMethod:#"POST"];
// set Content-Type in HTTP header

[request setValue:contentType forHTTPHeaderField: #"Content-Type"];
// post body
NSMutableData *body = [NSMutableData data];
// add params (all params are strings)
for (NSString *param in _params) {
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"\r\n\r\n", param] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"%#\r\n", [_params objectForKey:param]] dataUsingEncoding:NSUTF8StringEncoding]];
}
// add image data
NSData *imageData = UIImageJPEGRepresentation(imageToPost, 1.0);
if (imageData) {
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];

// set the content-length
NSString *postLength = [NSString stringWithFormat:#"%d", [body length]];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
// set URL
[request setURL:requestURL];
Note
"BoundaryConstant" is basically the variable "boundary" which is essentially a random (NSString *), "FileParamConstant" is basically your "filename.jpg"
You can also do by importing ASIFormDataRequest calss,Here is the link which tells Why to use this,after downloading classes just do like this,
uploading image to server using ASIFormDataReqest

In the Similar manner you can add as many paramters as you want .
I have to upload an image to a specific url. The specifications that I have to follow are these:
1. Method should be post
2. Image must be uploaded using multipart HTTP content type
3. The name of the HTTP field should be “uploadingTheFile”.
4. Multipart data shiuld have filename.
5. Image content type should be among following-jpeg,jpg,png,gif
I want to upload using NSURLConnection asynchronously. I think I am not able to set the parameters in the request in a proper way.I am getting status code as 200 which suggests that there is no problem with my NSURLConnection delegate methods. The code that I am trying is :
NSString *stringBoundary=#"0xKhTmLbOuNdArY";
// create request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:url]];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:30];
[request setHTTPMethod:#"POST"];
[request setValue:[NSString stringWithFormat:#"multipart/form-data; boundary=%#",stringBoundary] forHTTPHeaderField:#"uploadfile"];
NSMutableData *postBody = [NSMutableData data];
NSData *imageData=UIImagePNGRepresentation([UIImage imageNamed:#"IMG_0215.JPG"]);
//[postBody appendData:imageData];
[postBody appendData:[#"Content-Disposition: form-data; name=\"data;filename=\"media.png\"\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[NSData dataWithData:imageData]];
[postBody appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postBody];
NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
if (connection) {
self.data = [NSMutableData data];
}
I am using following code and it is working fine for me.

Here you can learn how to use afnetworking for upload images
https://github.com/AFNetworking/AFNetworking/wiki/AFNetworking-FAQ
You can use AFNetworking (it is opensource), here is code that worked for me. This is for AFNetworking 3.0 version.
NSString *serverUrl = [NSString stringWithFormat:#"http://www.yoursite.com/uploadlink", profile.host];
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] requestWithMethod:#"POST" URLString:serverUrl parameters:nil error:nil];
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
NSURL *filePath = [NSURL fileURLWithPath:[url path]];
NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:^(NSProgress * _Nonnull uploadProgress) {
// This is not called back on the main queue.
// You are responsible for dispatching to the main queue for UI updates
dispatch_async(dispatch_get_main_queue(), ^{
//Update the progress view
LLog(#"progres increase... %# , fraction: %f", uploadProgress.debugDescription, uploadProgress.fractionCompleted);
});
} completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
if (error) {
NSLog(#"Error: %#", error);
} else {
NSLog(#"Success: %# %#", response, responseObject);
}
}];
[uploadTask resume];
I am new to iPhone and using XML in my application where i need to send one image to the server's one specific folder. For the same i am using the code :

To upload data from your iPhone to your server:
- (void)sendImage {
NSData *postData = [nsdata from your original image];
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://yoururl.domain"]]];
[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];
}
i want to post xml data in following format:
<?xml version="1.0" encoding="UTF-8"?>
<data>
<email>xyz#domain.com</email>
<password>xyz123</password>
</data>
and receive in following format from the webserver
<?xml version="1.0" encoding="UTF-8"?>
<user>
<user_id>12</user_id>
</user>
help is appreciate
now i am trying to use NSUrlConnection and NSMutableRequest
i can post data on name like form post,but i want to post just xml data.
i have also tried to used ASIHTTPRequest .
any code or link is highly appriciated.
//prepare request
NSString *urlString = [NSString stringWithFormat:#"http://urlToSend.com"];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
//set headers
NSString *contentType = [NSString stringWithFormat:#"text/xml"];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
//create the body
NSMutableData *postBody = [NSMutableData data];
[postBody appendData:[[NSString stringWithFormat:#"<xml>"] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:#"<yourcode/>"] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:#"</xml>"] dataUsingEncoding:NSUTF8StringEncoding]];
//post
[request setHTTPBody:postBody];
//get response
NSHTTPURLResponse* urlResponse = nil;
NSError *error = [[NSError alloc] init];
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];
NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(#"Response Code: %d", [urlResponse statusCode]);
if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300) {
NSLog(#"Response: %#", result);
//here you get the response
}
Of course you can also use asynchronous request. Then you have to implement delegate.
Edit. you can also try this:
NSString* boundary = #"---------------------------14737809831466499882746641449";
NSMutableData* postbody = [NSMutableData dataWithCapacity: 200];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n", _boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"; filename=\"content.xml\"\r\n", name] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithString:#"Content-Type: text/xml\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:#"%#\r\n", val] dataUsingEncoding: NSUTF8StringEncoding]];
NSMutableURLRequest* requestURL= [[[NSMutableURLRequest alloc] init] autorelease];
[requestURL setURL:[NSURL URLWithString: _request.text]];
[requestURL setHTTPMethod:#"POST"];
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#", boundary];
[requestURL addValue:contentType forHTTPHeaderField: #"Content-Type"];
[requestURL addValue: [NSString stringWithFormat:#"%d",[postbody length]] forHTTPHeaderField: #"Content-length"];
[requestURL setHTTPBody: postbody];
and finally i used library from http://allseeing-i.com/ASIHTTPRequest/
and posted from following code:
NSURL *url = [NSURL URLWithString:#"http://url to post data"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request addPostValue:#"test name" forKey:#"name"];
[request setDelegate:self];
[request startSynchronous];
and used delegate method to receive data or error.
- (void)requestFinished:(ASIHTTPRequest *)request
{
// Use when fetching text data
NSString *responseString = [request responseString];
NSLog(#"%#",responseString);
// Use when fetching binary data
NSData *responseData = [request responseData];
}
- (void)requestFailed:(ASIHTTPRequest *)request
{
NSError *error = [request error];
NSLog(#"Error %#",error);
}
