I am receiving the unauthorized BBVA APIData error. The code Im using in Xcode as Objective-C for get the data is this:
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"https://api.bbva.com/apidatos/zones/cards_cube.json?date_min=201301&date_max=201307&group_by=week"]];
[request setHTTPMethod:#"GET"];
[request setValue:#"application/json;charset=UTF-8" forHTTPHeaderField:#"Authorization: Y2hvbWFsaS1hcHA6MGM2ZTljNjgxODNiZmUzOWY2OGJiYjY1NjZlZmU4ZTE3MzI0NTcyOQ=="];
NSURLResponse *response;
NSData *GETReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];
NSString *theReply = [[NSString alloc] initWithBytes:[GETReply bytes] length:[GETReply length] encoding: NSASCIIStringEncoding];
NSLog(#"Reply: %#", theReply);
This is the documentation I used: https://developer.bbva.com/api/api-datathon/section/api-reference
I would think that, in line 4, it should be
[request setValue: Y2hvbWFsaS1hcHA6MGM2ZTljNjgxODNiZmUzOWY2OGJiYjY1NjZlZmU4ZTE3MzI0NTcyOQ== forHTTPHeaderField:#"Authorization:"];
You might have to remove the colon after "Authorization:"

this is my screenshot[I searched for solution of this but did not get any solution. why it shows me an error displayed in screenshot. please help me.
NSURL *url=[NSURL URLWithString:#"http://www.gourmet7.com/auth"];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%lu", (unsigned long)[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error = [[NSError alloc] init];
NSHTTPURLResponse *response = nil;
NSData *urlData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(#"Response code: %ld", (long)[response statusCode]);
NSString *responseData = [[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];

It can only be a wild guess, but as your code compiles just fine, I think you're targeting some iOS version lower than 8.0.
Unfortunately, the HTTPBody property is only available since 8.0. So you either have to raise the minimum iOS version to at least 8.0 or use another mechanism.
How can I get JSON from a URL and encode NSString to show using NSLog?
The JSON contains Chinese words.
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"http://jxdp.mnks.cn/read.php?xCode=6beff&Code=6beff&Type=1&&top=5&min=0&CALL="]];
[request setHTTPMethod:#"GET"];
NSURLResponse *requestResponse;
NSData *requestHandler = [NSURLConnection sendSynchronousRequest:request returningResponse:&requestResponse error:nil];
NSString *requestReply = [[NSString alloc] initWithBytes:[requestHandler bytes] length:[requestHandler length] encoding:NSUTF8StringEncoding];
NSLog(#"requestReply: %#", requestReply);
I need to make a HTTPS post request to a server using a synchronous connection. I've made plenty of http connections but for some reason the code doesn't work with https and I'm sure the website address is right.
Some of my code:
Note that dparam is a dictionary object.
NSError *err;
NSData *parameterJSONData = [NSJSONSerialization dataWithJSONObject:dparam options:
NSJSONWritingPrettyPrinted error:&err];
NSString *param = [[NSString alloc] initWithData:parameterJSONData encoding:NSUTF8StringEncoding];
NSString *post =[[NSString alloc] initWithFormat:#"varnameOne=%#&varnameTwo=%#¶m=%#",vone,vtwo,param];
//my_url is a string defined elsewhere
NSURL *url=[NSURL URLWithString:my_url];
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];
NSError *error = [[NSError alloc] init];
NSHTTPURLResponse *response = nil;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
I need to do this synchronously as I don't really have the time to change all my database calls to asynchronous and the calls need to either complete or fail before the program continues so it'd have to be made effectively synchronous anyway.
That said I did try a synchronous route but it didn't work with https only http.
Hi Please help me how to prepare NSMutableURLRequest for below api
URL : www.XXXXXXXX.com/api.php
For Login :-
www.XXXXXXXXXXXX.com/api.php?task=login
POST Data :-
"email" => User's email
"pw" => User's Password
json response: session id on successful login
Am trying like this.
NSMutableURLRequest *request;
request=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"www.XXXXXXXX.com/api.php?task=login"]];
[request setHTTPMethod:#"POST"];
NSString *postString =#"email=xxxxxxxx#gmail.com&pw=1234";
[request setValue:[NSString
stringWithFormat:#"%d", [postString length]] forHTTPHeaderField:#"Content-length"];
[request setHTTPBody:[postString
dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *connection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
One reason could be that you forgot to add the "http:" scheme:
[NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://www.XXXXXXXX.com/api.php?task=login]];
HERE --^
Note also that the correct way to set body data and in particular the length is
NSString *postString =#"email=xxxxxxxx#gmail.com&pw=1234";
NSData *postData = [postString dataUsingEncoding:NSUTF8StringEncoding];
[request setValue:[NSString stringWithFormat:#"%d", [postData length]]
forHTTPHeaderField:#"Content-length"];
[request setHTTPBody:postData];
because the length of the UTF-8 encoded data can be different from the (Unicode) string length.
I ran into this error when I specified my base URL with a variable that accidentally contained a new line.
Try this:
NSError *error;
NSString *jsonString;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:jsonData1
options:0 error:&error];
if (!jsonData) {
NSLog(#"Got an error: %#", error);
} else {
jsonString= [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
}
NSData *postData = [[[NSString alloc] initWithFormat:#"method=methodName&email=%#&password=%#", user_name, pass_word] dataUsingEncoding:NSUTF8StringEncoding];
NSString *postLength = [NSString stringWithFormat:#"%ld",[postData length]];
jsonData=[jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:URL]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"\"Accept\""];
[request setValue:#"application/json" forHTTPHeaderField:#"\"Content-Type\""];
[request setValue:postLength forHTTPHeaderField:#"\"Content-Length\""];
[request setValue:#"application/x-www-form-urlencoded; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:jsonData];
NSError *requestError = [[NSError alloc] init];
NSHTTPURLResponse *response = nil;
NSData *urlData = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response
error:&requestError];
if ([response statusCode] >= 200 && [response statusCode] < 300) {
NSError *serializeError = nil;
NSString* newStr = [NSString stringWithUTF8String:[urlData bytes]];
NSDictionary *jsonData = [NSJSONSerialization
JSONObjectWithData:urlData
options:NSJSONReadingAllowFragments
error:&serializeError];
NSLog(#"recdata %#",jsonData);
}
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (connection)
{
NSLog(#"theConnection is succesful");
}
[connection start];
// 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
