I am trying to create a POST request. I am creating a custom URL but when I try and print out values I get the following errors:
EDIT:
(lldb) po request.HTTPBody
error: property 'HTTPBody' not found on object of type 'NSMutableURLRequest *'
(lldb) po request.HTTPMethod
error: property 'HTTPMethod' not found on object of type 'NSMutableURLRequest *'
Here is my code:
NSString *post = [NSString stringWithFormat:#"&serviceTicket=%#&tags=%#&tags=%#",taskId,fullName,#"test1"];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:webUrl]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Current-Type"];
[request setHTTPBody:postData];
NSURLConnection *conn = [[NSURLConnection alloc]initWithRequest:request delegate:self];
if(conn)
{
NSLog(#"Connection Successful");
}
else
{
NSLog(#"Connection could not be made");
}
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:webUrl]];
What am I missing?

I have this json:
{"myFriends":{"userId":"the user id", "userName":"the user name", "friends":[{"u":"friend user id","n":"friend user name"},{"u":"friend user id","n":"friend user name"}]}}
and I want to send him in post request to the server, this is the current way I am trying to do this:
+(NSData *)postDataToUrl:(NSString*)urlString :(NSString*)jsonString
{
NSData* responseData = nil;
NSURL *url=[NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
responseData = [NSMutableData data] ;
NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:url];
NSString *bodydata=[NSString stringWithFormat:#"%#",jsonString];
[request setHTTPMethod:#"POST"];
NSData *req=[NSData dataWithBytes:[bodydata UTF8String] length:[bodydata length]];
[request setHTTPBody:req];
NSURLResponse* response;
NSError* error = nil;
responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(#"the final output is:%#",responseString);
return responseData;
}
The json string contains the json, but for some reason the server always get nil and return error. How to fix this?
It would certainly help to tell your server about the content type:
[request addValue:#"application/json"
forHTTPHeaderField:#"Content-Type"];
Furthermore: in my own code I use:
[request setHTTPBody:[bodydata dataUsingEncoding:NSUTF8StringEncoding]]
This is my code for POST request with an NSData parameter:
- (void)uploadJSONData:(NSData*)jsonData toPath:(NSString*)urlString {
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:kRequestTimeout];
[request setHTTPMethod:#"POST"];
[request setHTTPBody: data];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%lu", (unsigned long)[data length]] forHTTPHeaderField:#"Content-Length"];
// Create url connection and fire request
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:NO];
[connection scheduleInRunLoop:[NSRunLoop mainRunLoop] forMode:NSDefaultRunLoopMode];
[connection start];
}
This is for an asynchronous request, but it should work just fine for synchronous. The only thing I see you might be missing is the "Content-Length" parameter.
i need to post my value to the test WebView i try'd but my value didnt post and no change while iam running
NSString *post = [NSString stringWithFormat:#"643c30f73a"];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:[NSString stringWithFormat:#"XXXXX.com"]]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Current-Type"];
[request setHTTPBody:postData];
NSURLConnection *conn = [[NSURLConnection alloc]initWithRequest:request delegate:self];
Are you implementing the required delegate methods for NSURLConnection?
See the documentation at https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/URLLoadingSystem/Tasks/UsingNSURLConnection.html for details and example implementations.
Implementing the delegate methods will at least give you an indication of any error that is occurring.
its worked for me,
NSURL *url = [NSURL URLWithString: #"http://your_url.com"];
NSString *body = [NSString stringWithFormat: #"arg1=%#&arg2=%#", #"val1",#"val2"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL: url];
[request setHTTPMethod: #"POST"];
[request setHTTPBody: [body dataUsingEncoding: NSUTF8StringEncoding]];
[webView loadRequest: request];
NSString * aToken = [[[NSUserDefaults standardUserDefaults] arrayForKey:#"accessToken"] firstObject];
NSString * post = [NSString stringWithFormat:#"code=%#", #"035571"];
NSData * postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString * postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest * request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"url"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
[request setValue:#"no-cache" forHTTPHeaderField:#"Cache-Control"];
[request setValue:[NSString stringWithFormat:#"Bearer %#", aToken] forHTTPHeaderField:#"Authorization"];
NSURLConnection *conn = [[NSURLConnection alloc]initWithRequest:request delegate:self];
[conn start];
the error is: {"error":"invalid_request","error_description":"Required field is missing. 'code'"}
how to fix it? any idea?
// Web service request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString: urlLoc]];
NSString *postLength = [NSString stringWithFormat:#"%d", [requestData length]];
[request setHTTPMethod: #"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody: requestData];
NSError *respError = nil;
NSData *returnData = [NSURLConnection sendSynchronousRequest: request returningResponse: nil error: &respError ];
//returndata is response of webservice
NSString *responseString = [[NSString alloc] initWithData:returnData encoding: NSUTF8StringEncoding];
NSDictionary *results = [responseString JSONValue] ;
NSLog(#"chat data- %#",results);
NSString *strResults = [results objectForKey:#"d"];
NSLog(#"result string is-%#",strResults);
this is the code that I am using for my Data fetching from web service. But i have to do this every time when come to this page.
Is that any method that can store my data in Cache memory so i need not to request every time.
I Am using
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
but i dont know how to use - (NSCachedURLResponse *) connection this method
thanks...
You need to use cache as of your needs according to this documentation: whenever you requesting a NSMutableURLRequest...
For Ex:
[NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString] cachePolicy:NSURLRequestReloadRevalidatingCacheData timeoutInterval:60];
For More details Kindly look into the Documentation
Iam sending JSON Object request to the server but server returns Status Code 405. how to solve this problem. please any one help me.
My code :
+(NSData *)GpBySalesDetailed:(NSMutableDictionary *)spDetailedDict{
NSLog(#"spDetailedDict:%#",spDetailedDict);
NSString *dataString = [spDetailedDict JSONRepresentation];
NSLog(#"%#dataString",dataString);
return [dataString dataUsingEncoding:NSUTF8StringEncoding];
}
-(void)requestWithUrl:(NSURL *)url WithJsonData:(NSData *)JsonData
{
NSMutableURLRequest *urlRequest=[[NSMutableURLRequest alloc]initWithURL:#"http://srbisolutions.com/SmartReportService.svc/GpBySalesPersonDetailed];
if (JsonData != nil) {
[urlRequest setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[urlRequest setHTTPMethod:#"POST"];
[urlRequest setHTTPBody:JsonData];
}
else
{
[urlRequest setHTTPMethod:#"GET"];
}
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:urlRequest delegate:self startImmediately:YES];
[conn start];
}
HTTP Code 405 means "Method not allowed", it does not accept a post request for this particular URI. Either the server must be configured to accept POST requests or it should offer another URI.
try this
NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:YOURURL
cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:10.0 ];
NSLog(#"final request is %#",request);
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
//Here postData is a Dictionary with key values in web services format use ur own dic
[request setHTTPBody:[[self convertToJSON:postData] dataUsingEncoding:NSUTF8StringEncoding]];
NSString *contentLength = [NSString stringWithFormat:#"%d",[[request HTTPBody] length]];
[request setValue:contentLength forHTTPHeaderField:#"Content-Length"];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (connection)
{
self.responseData = [NSMutableData data];
}
//============JSON CONVERSION========
-(NSString *)convertToJSON:(id)requestParameters
{
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:requestParameters options:NSJSONWritingPrettyPrinted error:nil];
NSLog(#"JSON DATA LENGTH = %d", [jsonData length]);
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
NSLog(#"JSON STR LENGTH = %d", [jsonString length]);
return jsonString;
}
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"yourURL"]];
[theRequest setHTTPMethod:#"POST"];
NSDictionary *jsonRequest =
[NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:#//add your objects
]
forKeys:[NSArray arrayWithObjects:
title,
link,
nil]];
NString *jsonBody = [jsonRequest JSONRepresentation];
NSLog(#"The request is %#",jsonBody);
NSData *bodyData = [jsonBody dataUsingEncoding:NSUTF8StringEncoding];
[theRequest setHTTPBody:bodyData];
[theRequest setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
// create the connection with the request
// and start loading the data
theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
