I am using AFNetwork 3.0 for HTTP get request.
I am even getting response. But i want to take response data as NSString.
Can someone please help me how to get response data as NSString
Here is my code,
AFHTTPSessionManager *operation = [AFHTTPSessionManager alloc];
[operation GET:controlURL.absoluteString parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"JSON: %#", responseObject);
NSLog(#"success: %#", responseObject);
NSString *xmlString = [responseObject ];// i am facing problem here
If you want response data in your string then try this:
NSString *str = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(#"responseData: %#", str);

Hii I am using afnetworking from post array data to sent server side here is my code ...
NSMutableDictionary *dict1=[[NSMutableDictionary alloc]initWithObjectsAndKeys:#"online_status",#"option_name",dict[#"option_value"],#"option_value", nil];
NSArray *arr1=[[NSMutableArray alloc]initWithObjects:dict1, nil];
NSMutableDictionary *dict2=[[NSMutableDictionary alloc]initWithObjectsAndKeys:[UserDefaults valueForKey:#"user_id"],#"user_id",arr1,#"option_array", nil];
NSError *error = nil;
NSString *createJSON = [[NSString alloc] initWithData:[NSJSONSerialization dataWithJSONObject:dict2
options:NSJSONWritingPrettyPrinted
error:&error]
encoding:NSUTF8StringEncoding];
NSDictionary *pardsams = #{#"data": createJSON};
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSLog(#"Dict %#",pardsams[#"data"]);
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:#"text/html"];
[manager POST:[NSString stringWithFormat:#"%#set_user_multiple_options",K_APP_URL] parameters: pardsams[#"data"] success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
and getting server responce is :
message = "Required parameters missing.";
status = 0;
i will hit the request to rest client but where getting correct responce saved data bt trying to do in code it not working polease... help me
This is my Code:
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionary options:0 error:nil];
NSString *json = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
NSDictionary *dict = #{#"body":json};
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager POST:#"http://abc/" parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSString *myString = [[NSString alloc] initWithData:operation.request.HTTPBody encoding:NSUTF8StringEncoding];
NSLog(#"Error: %#", myString);
}];
But i am Getting Error Like This
body=%7B%22pincode%22%3A%22gfgfgf%22%2C%22mobile%22%3A%221111%22%2C%22password%22%3A%22rwerew%22%2C%22profile_pic%22%3A%22%22%2C%22social_accesstoken%22%3A%22%22%2C%22sponsor_choice%22%3A3%2C%22sponsor_id%22%3A%22%22%2C%22social_provider%22%3A%22Normal%22%2C%22email%22%3A%22ghffh%22%2C%22gender%22%3A1%2C%22name%22%3A%22narendra%22%2C%22nickname%22%3A1233%2C%22country%22%3A%22Japan%20%28JPY%29%22%2C%22fromLogin%22%3A%22%22%2C%22methodName%22%3A%22signup%22%2C%22birth_date%22%3A%2208-06-01%22%7D
Can any one suggest me on this kind...
There is no need to convert error to encoded string....
First of all clear that.. which type of parameter you needed..
and then try this code for simple posting data:
(Make related changes according to your parameters needed)
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
NSDictionary *param = # {#"body":json};
[manager POST:URL_HERE parameters:param
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"JSON: %#", responseObject);
}
failure:
^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
I am getting this error while posting json to url :
Invalid top-level type in JSON write'
I am even sending perfect JSON using afnetworking post request code But it keeps giving me error.
My code :
NSString * serviceType = #"xyz";
NSString * remarks =#"project deadline is near ";
NSString * emailId = #"xyx.live.com";
NSDictionary *params =
# {
#"serviceType" :serviceType,
#"remarks" :remarks,
#"emailId" :emailId
};
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:params
options:0
error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
AFHTTPRequestOperationManager *manager2 = [AFHTTPRequestOperationManager manager];
AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
[serializer setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[serializer setValue:#"application/json" forHTTPHeaderField:#"Accept"];
manager2.requestSerializer = serializer;
[manager2 POST:#"http://xyx.com" parameters:jsonString success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON_post_fzzlogin: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
//here is place for code executed in success case
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error while sending POST"
message:#"Sorry, try again."
delegate:nil
cancelButtonTitle:#"Ok"
otherButtonTitles:nil];
[alertView show];
NSLog(#"Error: %#", error);
}];
Please help me out this regard .thanks in advance
You are trying to encode request twice because you set request serializer for AFHTTPRequestOperationManager and provide parameters as encoded JSON string. So you need to provide raw parameters if you want to use request serializer or don't use it and encode to JSON manually.
This is how you post JSON or rather NSDictionary by AFNetworking
NSDictionary *dict = #{#"Key":#"Value"};
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:[Util urlAppend:kListOfArticleCatagory] parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSDictionary *responseObj = (NSDictionary *)responseObject;//casting to NSDictionary from id
NSLog(#"%#",responseObj);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Something went wrong :%#",operation.responseString);
}];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"text/html"];
}
You dont post JSON through AFNetworking, rather the NSDictionary as the parameters, it will get converted to JSON as you post it.
Usually, to download a JSON, I use AFNetworking creating a singleton with this code
- (void)getJSON {
NSURLRequest * request =
[NSURLRequest requestWithURL:
[NSURL URLWithString:#"http://URL"]];
AFJSONRequestOperation * operation =
[AFJSONRequestOperation JSONRequestOperationWithRequest:request
success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
NSArray * js = JSON;
[_delegate dati:js];
NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString * filePath = [[paths lastObject] stringByAppendingPathComponent:#"downloaded.json"];
NSData * data = [NSJSONSerialization dataWithJSONObject:JSON
options:NSJSONWritingPrettyPrinted
error:NULL];
[data writeToFile:filePath
atomically:YES];
}];
[operation start];
}
and calling this code in View Controller
[[DataManager sharedClass] getJSON];
and it works, but now I need to send (post) some parameters (as an authorization code, GPS coordinates, user's mail or something similar) into the request to the server to receive a specific JSON. Server is already configured and it works fine, but I can't find a guide to modify my code to do that. Does somebody knows how to proceed?
This is an example of posting data to server using JSON, for example the json is below:
NSDictionary *json = #{#"authorization_code": yourAuthorizationCode,#"gps": #{#"lat": latitude,#"lng": longitude},#"email":email};
JSON Posting
Posting on server depends also on your server requirements, so if it requires a JSON to post, this is the way:
//Create an AFHTTPRequestOperationManager
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
//Depending if you need a HTTP header, you create one
[manager.requestSerializer setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
NSString *yourAuthorizationCode;
NSString *latitude;
NSString *longitude;
NSString *email;
//My data to be posted via JSON
NSDictionary *json = #{#"authorization_code": yourAuthorizationCode,#"gps": #{#"lat": latitude,#"lng": longitude},#"email":email};
//Sending Post Method, with parameter JSON
[manager POST:#"http://myphp.com/api/v1/profile" parameters:json success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"JSON: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"Error at creating post: %#", error);
}];
Parameters posted via URL
In this method parameters are passed in URL, and you post them to server in URL form
//Create an AFHTTPRequestOperationManager
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSString *yourAuthorizationCode;
NSString *latitude;
NSString *longitude;
NSString *email;
//Sending Post Method, with parameter JSON (You can change your method of sending data to server just by replacing POST with GET)
[manager POST:[NSString stringWithFormat:#"http://myphp.com/api/v1/profile?authorization_code=%#&gps_lat=%#&gps_lng=%#&email=%#",yourAuthorizationCode,latitude,longitude,email] parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"JSON: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"Error at creating post: %#", error);
}];
Hope it helps, give me feedback!
I
ve been using AFNetworking 2 with success for some time, but I stumbled upon case where I don't know where to turn my head to. I have to make POST request in order to log in, send credentials alongside and receive JSON back with operation status. For some weird reason sending it via AFNetworking like this:
NSDictionary *params = #{#"login": self.loginField.text, #"password" : self.passField.text};
NSDictionary *data = #{#"data": params};
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
//manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager POST:server parameters:#{#"data" : params} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"success: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"error: %#", error);
}];
I have to pack dictionary with parameters as a single "data" parameter. I do get back OK 200, but if I take a look in server logs I see that no data was transferred, which ended up as user not recognized.
But if send with curl this:
curl -d 'data={"login":"xx", "password":"yy"}' http://someurl/api/login/
I got perfectly fine response and in logs I see some actual data. Does anyone know how to deal with such a case?
If it helps, I'm doing it in iPhone simulator, not tested on actual device.
If you have a look at the AFNetworking source code, namely the class AFJSONRequestSerializer, you will see that the serialise function for that serialiser puts the parameters you hand over into the body - and not as an HTTP parameter as you expect.
You should use an AFHTTPRequestSerializer in your case - that will add the parameters as (URL-encoded) HTTP parameters to your URL.
Something like that should work in your case:
// build the JSON parameter string
NSDictionary *params = #{#"login": self.loginField.text, #"password" : self.passField.text};
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:params
options:0
error:&error];
NSString *jsonString = [[NSString alloc] initWithBytes:[jsonData bytes]
length:[jsonData length]
encoding:NSUTF8StringEncoding];
// and now send the JSON parameter string as HTTP parameter
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
[manager POST:server
parameters:#{#"data" : jsonString}
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"success: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"error: %#", error);
}];
