I'm trying to use paypal Express checkout from a native iOS app (can't use paypal SDK because apple needs me to go through safari to make the payment). Problem is when i try to call the SetExpressCheckout API method. Here is the curl statement that they provide at the website:
curl -s --insecure https://api-3t.sandbox.paypal.com/nvp -d
"USER=callerID # User ID of the PayPal caller account
&PWD=callerPswd # Password of the caller account
&SIGNATURE=callerSig # Signature of the caller account
&METHOD=SetExpressCheckout
&VERSION=93
&PAYMENTREQUEST_0_PAYMENTACTION=SALE # type of payment
&PAYMENTREQUEST_0_AMT=19.95 # amount of transaction
&PAYMENTREQUEST_0_CURRENCYCODE=USD # currency of transaction
&RETURNURL=http://www.example.com/success.html # URL of your payment confirmation page
&CANCELURL=http://www.example.com/cancel.html" # URL redirect if customer cancels payment
I need to pass this to AFNetworking so i can do it inside the app, i've tried this but it's not working:
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: kPaypalClientId,#"USER",
kPaypalPassword, #"PWD",
kPaypalSignature, #"SIGNATURE",
#"SetExpressCheckout", #"METHOD",
#"93", #"VERSION",
#"SALE",#"PAYMENTREQUEST_0_PAYMENTACTION",
#"19.95",#"PAYMENTREQUEST_0_AMT",
#"USD", #"PAYMENTREQUEST_0_CURRENCYCODE",
#"shareapp://bien",#"RETURNURL",
#"shareapp://cancel", #"CANCELURL", nil];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager.requestSerializer setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[manager POST:#"https://api-3t.sandbox.paypal.com/nvp" parameters:params
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"%#", responseObject);
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:#"https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=%#",tokenValue]]];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
This is the error i'm getting:
Error Domain=AFNetworkingErrorDomain Code=-1016 "Request failed: unacceptable content-type: text/plain" UserInfo=0xba7de40 {NSErrorFailingURLKey=https://api-3t.sandbox.paypal.com/nvp, AFNetworkingOperationFailingURLResponseErrorKey=<NSHTTPURLResponse: 0xd06e720> { URL: https://api-3t.sandbox.paypal.com/nvp } { status code: 200, headers {

Thank you and sorry for my english!!
This line solved this for me:
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
You need to set the header: Content-Type: application/x-www-form-urlencoded when posting to the Paypal server.

I'm trying to make a GET request setting a header called

You're definitely getting a 401 back from the server - meaning you haven't constructed an appropriate HTTP request with authentication according to what the server requires. Review the documentation of the (service provider or in your case what appears to be a local packaged product), then use tools like curl and postman to construct an appropriate HTTP request. When you're confident the raw requests are working as expected, use something like requestb.in to test your AFNetworking request.
For what it's worth, X-User-Authorization isn't a pre-configured authorization header (The X- prefix implies it's a custom header attribute). Maybe you're looking for something more like Authorization: Bearer <token>?
Hi I have one example url Which returns JSON Format. but when i use AFNetWorking2.0 to get the response from that URL, i am not getting correct Response. Here i am sending my code also.
- (void)testHTTPS {
AFSecurityPolicy *securityPolicy = [[AFSecurityPolicy alloc] init];
[securityPolicy setAllowInvalidCertificates:YES];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
//manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager setSecurityPolicy:securityPolicy];
[manager GET:#"xxxxx"
parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
NSString* newStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:nil];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
}
I am getting JSON Dic always nil. and if i print "newstr" i am getting html format response. can anyone please find correct way?
I have done as you said John but i am getting the below result

The problem is that you're using the AFHTTPResponseSerializer rather than AFNetworking's AFJSONResponseSerializer. Therefore, when the response comes in, it is parsing it as a HTTP response rather than a JSON response. This is easily fixed by assigning your manager.responseSerializer to AFJSONResponseSerializer instead:
manager.responseSerializer = [AFJSONResponseSerializer serializer];
You'll find that you won't need to create an NSDictionary from the response - upon success it should come through as an NSDictionary object already.
Check out the AFNetworking 2.0 migration guide. It's a very handy read and will make you aware of what to look out for in the future.
I'm trying to send request to OpenStreetMap api, and I'm still failing to do so. Please help me out what's incorrect.
My method:
NSString *url = #"http://api.openstreetmap.fr/xapi?node[name=London]";
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"application/osm3s+xml"];
[manager setResponseSerializer:[AFXMLParserResponseSerializer new]];
[manager GET:url parameters:nil success:^(AFHTTPRequestOperation *operation, NSData *responseObject) {
NSLog(#"DATA: %#", responseObject);
[self stopProgress];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
self.textView.text = error.description;
[self stopProgress];
}];
Error:

Your code:
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"application/osm3s+xml"];
Very clearly creates the header that OpenStreetMap is rejecting. Don't set that header: set it to a value like text/xml, which is documented as the right value.
I set up a simple web server on an AWS EC2 instance and wrote a small test.php file that goes like this:
<?php
$dict = array("key" => "value", "test" => "Hello world");
echo json_encode($dict);
?>
In my browser I can go to http://'myInstanceIP'/test.php and I will get the encoded JSON response. I tried doing this in iOS and for some reason I can only get a successful response via NSURLConnection and not through AFNetworking. It's weird because the AFN code works if I input some other URL that will give me a JSON response, just not on my URL.
I call it in viewDidAppear just for testing:
- (void)viewDidAppear:(BOOL)animated
{
NSString *urlString = #"http://54.183.178.170/test.php";
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.responseSerializer = [AFJSONResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"%#", (NSDictionary *)responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Failed");
}];
[operation start];
}
I can't tell if it's the fault of my web server or AFN (since it works on NSURLConnection).
UPDATE:
Here's the failure code I'm getting from AFNetworking:

We can see here:
Code=-1016 "Request failed: unacceptable content-type: text/html"
That your problem should be happening because of this line:
operation.responseSerializer = [AFJSONResponseSerializer serializer];
For some reason your server must be returning a non-JSON response, and you are using a JSONResponseSerializer. So if you fix the server return type the correct format you'll probably be fine.
Or, you could just change the serializer type like this:
operation.responseSerializer = [AFHTTPResponseSerializer serializer];
if it's just for a testing purpose.
So it turns out I need to add the following line to my PHP, right before json_encode():
header('Content-type: application/json');
Then it works with AFNetworking as it should.
Im using AFNetworking to get JSON values from my iOS application i have tested my code to this link http://gdata.youtube.com/feeds/api/standardfeeds/most_popular?v=2&alt=json then my code works fine. but when i use http://www.fr20.wearedesigners.net/WADMac/tourism/fetchGuideListAndroid.php this link to retrieve data im getting following Error please find below the code i used.please help me to retrieve data from my URL

Simply go to Serilization->AFURLResponseSerialization.m, line 215, and change it:
self.acceptableContentTypes = [NSSet setWithObjects:#"application/json", #"text/json", #"text/javascript",#"text/html", nil];
it will work you.
More recent versions may have the code on line 223.
Solution for Swift:
It will accept most of the content type.
let manager=AFHTTPRequestOperationManager()
manager.responseSerializer = AFJSONResponseSerializer(readingOptions: NSJSONReadingOptions.AllowFragments) as AFJSONResponseSerializer
manager.requestSerializer = AFJSONRequestSerializer() as AFJSONRequestSerializer
manager.responseSerializer.acceptableContentTypes = NSSet(objects:"application/json", "text/html", "text/plain", "text/json", "text/javascript", "audio/wav") as Set<NSObject>
The url you use (http://www.fr20.wearedesigners.net/WADMac/tourism/fetchGuideListAndroid.php ) returns a not accepted content-type header, instead of text/html it should return application/json.
As Otanaught says, the url you use (http://www.fr20.wearedesigners.net/WADMac/tourism/fetchGuideListAndroid.php ) returns a not accepted content-type header, instead of text/html it should return application/json.
If you have access to the PHP Web Service file, put this before any display code:
header('Content-type: application/json');
If u r using afnetwork 2.6.3 then
Simply go to Serilization -> AFURLResponseSerialization.m, line 224, and change it to:
self.acceptableContentTypes = [NSSet setWithObjects:#"application/json", #"text/json", #"text/javascript",#"text/html", nil];
it will work you.
