I am currently connecting my iOS native app to a facebook page in order to post a message to that wall. I can access the wall but for some reason there's no message text set. I asked the user for 'publish_stream' permissions.
Any idea what I'm doing wrong? Here's my code:
NSMutableDictionary *message = [NSDictionary dictionaryWithObjectsAndKeys:#"some text", #"message", #"http://path/to/itunes/", #"link", nil];
NSString *changeJSON = [message JSONRepresentation];
NSLog(#"changeJSON: %#", changeJSON);
NSData *myPostData = [changeJSON dataUsingEncoding:NSUTF8StringEncoding];
NSString *myURL = [NSString stringWithFormat:#"https://graph.facebook.com/pageId/feed?access_token=%#", facebook.accessToken];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:myURL] cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10.0];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [myPostData length] ] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: myPostData];
NSData *returnData = [NSURLConnection sendSynchronousRequest: request returningResponse: nil error: nil ];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding: NSUTF8StringEncoding];
NSLog(#"return string: %#", returnString);
[facebook logout:self];
The string which is encoded to a NSData object is the following:
{"message":"some text","link":"http://path/to/itunes/"}
Thanks and have a nice day :-)
It looks like you're attempting to post JSON to the GraphAPI? If so, you can't post JSON to Facebook, but instead have to use parameters when posting (either query string or HTTP request parameters).
All posting actions are done via HTTP POST with parameters and all responses are done in JSON. You can read more on this via the Graph API reference under publishing.
See: POST Reference.

I'm writing some with server API. I'm using RestKit but this question I wrote without. I don't understand why console request is working and my is not. Please help me with this.
-(void)uploadFile {
NSString *URLPath = [NSString stringWithFormat:#"https://api.interlabs.pro/v1/texts/23041/content"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:URLPath]];
[request setHTTPMethod:#"PUT"];

NSURLResponse *response;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
NSString *resSrt = [[NSString alloc]initWithData:responseData encoding:NSASCIIStringEncoding];
NSLog(resSrt);
}
And it's still doesn't not work, but console work perfectly
But enter link description here
update token link
The code works fine and result is that token is expired.
But you should not use deprecated methods like "NSURLConnection sendSynchronousRequest", then you should check error, when handling results from internet it is utf8 most of the time and not ascii. Then when logging strings use NSLog(#"%#", theString) to avoid problems if the content of theString contains formating specifiers.
I'm new to iOS and i'm using the following code to make API Calls.
-(NSData *)sendDataToServer:(NSString*)url :(NSString*)params
{
NSString *postDataString = [params stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(#"postDataString :%#",postDataString);
NSData *postData = [postDataString dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSString *urlReq = [NSString stringWithFormat:#"%#", url];
[request setURL:[NSURL URLWithString:urlReq]];
[request setTimeoutInterval:180];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:[params dataUsingEncoding:NSUTF8StringEncoding]];
responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(#"response in Server: %#",responseString);
return responseData;
}
I'm sending the following string as params to the above method. If I send the following data without special characters, I'm getting the success response.
If i Add any special charters as like (&) with json I'm always getting the invalid response, that is the server always returns null.
So Can anyone please provide any suggestion to get the right response when using json string with Special characters like '&' etc.,

You didn't post the percent encoded string, but the original string.
Code:
arrValues = [[NSMutableArray alloc]initWithObjects:#"Chennai", nil];
arrKeys = [[NSMutableArray alloc]initWithObjects:#"loc", nil];
dicValue = [NSDictionary dictionaryWithObjects:arrValues forKeys:arrKeys];
NSString *strMethodName = #"agentuserlist";
strUrlName = [NSString stringWithFormat:#"%#%#?filters=%#",appDelegate.strURL, strMethodName, dicValue];
//strUrlName = [strUrlName stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:strUrlName] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:250.0];
[request setHTTPMethod:#"GET"];
[request setHTTPShouldHandleCookies:YES];
[request setValue:#"zyt45HuJ70oPpWl7" forHTTPHeaderField:#"Authorization"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
NSError *error;
NSURLResponse *response;
NSData *received = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response error:&error];
NSLog(#"error:%#", error);
NSString *strResponse = [[NSString alloc]initWithData:received encoding:NSUTF8StringEncoding];
NSLog(#"response :%#", strResponse);
I try to send json argument through get method.It gives error as "unsupported url(-1002)".
The URL is working fine when I checked with Postman. I am unable to find out the problem.
Where I went wrong?
I think the problem lies in how you encode your NSDictionary in the NSURL.
You probably want your URL to look like this: http://my domain.com/agentuserlist?loc=Chennai. But the raw encoding of the NSDictionary inside the NSURL doesn't produce this result.
You can follow the accepted answer
from this question to get an idea of how to transform an NSDictionary into a regular list of URL parameters (with proper encoding of dictionary values: don't forget the stringByAddingPercentEscapeUsingEncoding part): Creating URL query parameters from NSDictionary objects in ObjectiveC
Hi I'm new to iphone development, I'm currently working with a project where I have a screen, in which user should enter their details, like username and password. I googled and find out about NSURLConnection for GET/POST/DELETE. I can GET data by the below codes,
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"http://************/api/Users"]];
[request setHTTPMethod:#"GET"];
[request setValue:#"application/json;charset=UTF-8" forHTTPHeaderField:#"Content-
Type"];
NSURLResponse *response;
NSData *GETData = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response error:nil];
NSString *ResultData = [[NSString alloc] initWithBytes:[GETData bytes] length:[GETData
length] encoding: NSASCIIStringEncoding];
NSLog(#"ResultData: %#", ResultData);
But for POST method, i doesn't get any ideas of , how it functions and how it store record to sql server database, can't understand whether it s storing data or not, i tried the following codes,
username = #"Aravind.k";
password = #"1234/";
email = #"sivaarwin#gmail.com";
NSString *post = [NSString stringWithFormat:#"FirstName=%#&LastName=%#&WorkEmailAddress=%#",
username, password, email];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding
allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"http://*********/api/Users"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded;charset=UTF-8"
forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSLog(#"request: %#", request);
NSLog(#"postData: %#", postData);
NSURLResponse *response;
NSData *POSTReply = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response
error:nil];
NSLog(#"POSTReply: %#", POSTReply);
NSString *theReply = [[NSString alloc] initWithBytes:[POSTReply bytes]
length:[POSTReply length]
encoding:NSASCIIStringEncoding];
NSLog(#"Reply: %#", theReply);
Same api url for both GET and POST, any suggestions regarding POST and DELETE will be grateful, Thanks in advance.And how we can get notified as the entered data is stored into the server.
First off: not checking for errors automatically leads to down votes ;)
Please edit your code with full error checks!
When using a MIME type application/x-www-form-urlencoded you need to properly encode the parameters.
I would suggest, to create a NSDictionary holding your parameters, e.g.:
NSDictionary* params = #{#"FirstName": firstName, #"LastName": lastName, #"password": password};
and then use the approach described in the following link to get an encoded parameter string suitable for using as a body data for a application/x-www-form-urlencoded message:
How to send multiple parameterts to PHP server in HTTP post
The link above implements a Category and a method dataFormURLEncoded for a NSDictionary which returns an encoded string in a NSData object:
NSData* postData = [params dataFormURLEncoded];
Note: The MIME type application/x-www-form-urlencoded does not have a charset parameter. It will be ignored by the server. You should set the header like below:
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
Otherwise, your code should work. I would strongly recommend to use the asynchronous version of the convenient method:
+ (void)sendAsynchronousRequest:(NSURLRequest *)request
queue:(NSOperationQueue *)queue
completionHandler:(void (^)(NSURLResponse*, NSData*, NSError*))handler
I'm trying to make a POST request using NSURLConnection. I use Charles to debug and Charles every time says that the method is GET. I've tried all different ways and can't get it to work. I am NOT using JSON.
-(void)getList
{
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
NSURL *url = [NSURL URLWithString:#"http://example.com/api/getList"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSString *radius = #"15";
NSString *latitude = #"-117.820833";
NSString *longitude = #"34.001667";
NSString *parameters = [NSString stringWithFormat:#"longitude=%#&latitude=%#&radius=%#", longitude,latitude, radius];
NSLog(#"PARAMS = %#", parameters);
NSData *data = [parameters dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPMethod:#"POST"];
[request setValue:#"text/plain" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:data];
NSURLResponse *response = nil;
NSError *error = nil;
NSData *result = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *responseString = [[NSString alloc]initWithData:result encoding:NSUTF8StringEncoding];
NSLog(#"RESULT = %#", responseString);
}
Does anybody know what am I doing wrong? When I access my web service it seems like I'm not posting anything. I'm getting empty response.
Please help with any ideas. I pretty much have to make a simple POST request. Maybe someone can help me debug this better.
If the server is redirecting your request for some reason (perhaps authentication) then the POST information can get lost.
