I am trying to connect to an Api but it is using x-www-form-urlencoded ...and i am using this code .Plz tell me the correct method
AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeNone];
securityPolicy.allowInvalidCertificates = YES;
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = nil;
manager.securityPolicy = securityPolicy;
[manager POST:[NSString stringWithFormat:#"#"%#%#phone=%#&password=%#",BASE_URL,API_LOGIN,phone,password]
parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject) {
successBlock(responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Server Error : %#", operation.responseString);
errorBlock(error);
}];
}
I think you should try to set the http header for 'x-www-form-urlencoded' to communicate with your backend:
[manager.requestSerializer setValue:#"application/x-www-form-urlencoded; charset=UTF-8" forHTTPHeaderField:#"Content-Type"];
If this does not fix your errors, then try to validate your json object.
You could also have a look to this question: AFNetworking 3 x-www-form-urlencoded post data

I am sending GET request to server to getting json response. When i first do it i get some response but then i make changes in the database but still i get the same josn which i was getting.But on browser the json is updated on app it is not updated.I have used below code to make it work but nothing works for me.
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:url]];
[manager.requestSerializer setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
AFJSONRequestSerializer *requestSerializer = [AFJSONRequestSerializer serializer];
[requestSerializer setValue:api_key forHTTPHeaderField:#"Authorization"];
manager.requestSerializer = requestSerializer;
AFJSONResponseSerializer *responseSerializer = [AFJSONResponseSerializer serializer];
responseSerializer.acceptableContentTypes = [NSSet setWithObjects:#"application/json", #"text/json", #"text/javascript", #"text/html", nil];
manager.responseSerializer = responseSerializer;
[manager GET:url parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"json is %#",responseObject);
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
[self activityIndicator:#"hide"];
NSLog(#"Error: %#", operation.responseString);
}];
I have tried reloadignoringcachedata but this does not work.
Firstly I tried the same web service with advanced rest client. it works fine. but i am having difficulty writing the equivalent in afnetworking.
here is the Webservice.
http://devmybartersite.pantheon.io/myrestapi/barter_user/create?str= {"email":"sahildgfdffdfduuy#gmail.com","pass":"hello"}
i am able to get the response in advanced rest client in chrome. Additionally need to set a X-CSRF-Token in the header.
Here is my code
- (IBAction)pressed:(id)sender {
NSLog(#"You entered %#",self.username.text);
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
//header fields
[manager.requestSerializer setValue:#"vZu-YUFWLzIdFIn7VDoA6hV9IhrYe-BimkC1ncRdojU" forHTTPHeaderField:#"X-CSRF-Token"];
[manager.requestSerializer setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
NSDictionary *params = # {#"user":#"kjhkhkjhmnbbnjhio#gmail.com", #"pwd":#"hello" };
[manager POST:#"http://dev-my-barter-site.pantheon.io/myrestapi/barter_user/create" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
}
Default requestSerializer will transform your parameters to the following format user=kjhkhkjhmnbbnjhio#gmail.com&pwd=hello. In order to get JSON formatted request body, use AFJSONRequestSerializer:
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:#"..." forHTTPHeaderField:#"..."];
[manager.requestSerializer setValue:#"..." forHTTPHeaderField:#"..."];
than you send request:
[manager POST:....]
I want to use AFNetworking class to my application to communicating with server.
I am new to this library . Here is my code:
NSDictionary *user=[[NSDictionary alloc]initWithObjectsAndKeys:#"hiteshp",#"userName",#"12345^",#"password", nil];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
AFHTTPRequestSerializer *requestSerializer = [AFHTTPRequestSerializer serializer];
[requestSerializer setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
manager.requestSerializer=requestSerializer; //[AFJSONRequestSerializer serializer];
[manager POST:#"myURL" parameters:user success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %# %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
I want to add header to this request . I tried but it is not working . If I wrote commented line then request is done but I also want to add one more field "Authorization" to requset.
Andhow to print request header?
I know it's too late but here's a code that makes what you want
NSString *finalyToken = [[NSString alloc]initWithFormat:#"Bearer %#",user.token];
AFHTTPRequestOperationManager *manager =
[[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:#"https://server1.appscserver.de/api"]];
[manager.requestSerializer setValue:finalyToken forHTTPHeaderField:#"Authorization"];
Hope it helps someone
Use this in your code:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:#"text/html", #"application/json", nil];
//Authorization
[manager.requestSerializer setAuthorizationHeaderFieldWithUsername:userName password:password];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
in php file add:
header('Content-type: application/json');
in xcode:
manager.responseSerializer = [AFJSONResponseSerializer serializer];
example xcode code:
NSDictionary *parameters = #{#"key1": #"value1",
#"key2": #"value2"};
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager POST:[NSString stringWithFormat:#"http://%#", Url] parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
I would like to make the following request from my app:
AFHTTPRequestOperationManager *requestManager = [[AFHTTPRequestOperationManager alloc] init];
requestManager.responseSerializer.acceptableContentTypes = [requestManager.responseSerializer.acceptableContentTypes setByAddingObject:#"application/json"];
requestManager.requestSerializer = [AFJSONRequestSerializer serializer];
[requestManager POST:urlString parameters:aParameters constructingBodyWithBlock:nil success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"%#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"error: %#", error);
}];
Where aParameters is an NSDictionary with the following content:
NSDictionary *urlParams = #{#"username" : anUser.userName, #"password" : anUser.password};
When I make the request from my app with the user input of "anUsername" and "aPassword" I get the following log for the body in my servlet:
--Boundary+5738A89B2C391231
Content-Disposition: form-data; name="password"
aPassword
--Boundary+5738A89B2C391231
Content-Disposition: form-data; name="username"
anUsername
--Boundary+5738A89B2C391231--
multipart/form-data; boundary=Boundary+5738A89B2C391231
I was under the impression that using AFJSONRequestSerializer would send my request in the appropriate format, but as the log shows, it's multipart/form data. It is really hard (for me) to parse this kind of request (I'm parsing it in Java on the server side), so my question is: is it possible to send a json in the body of my request? Something like this:
{
"userName" : "anUsername",
"password" : "aPassword"
}
Any help would be appreciated.
For anyone concerned: Instead of using the POST:parameters:constructingBodyWithBlock:success:failure: method, you should use POST:parameters:success:failure:. The former performs a multipart form request, while the latter does url form encoding. Additionally, to send the params in JSON, the requestSerializer property of the AFHTTPRequestOperationManager instance should be an instance of AFJSONRequestSerializer (by default it is set to AFHTTPRequestSerializer)
It is really helpful to browse the implementation file of AFHTTPRequestOperationManager for details, it helped me sort this error out.
You don't need to send pure JSON in POST request, just send Parameters dictionary. Here is the sample code that is working for POST Request.
+ (void)login:(BOUser *)user responseBlock:(APIRequestResponseBlock)responseBlock {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:#"parse-application-id-removed" forHTTPHeaderField:#"X-Parse-Application-Id"];
[manager.requestSerializer setValue:#"parse-rest-api-key-removed" forHTTPHeaderField:#"X-Parse-REST-API-Key"];
[manager.requestSerializer setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
manager.securityPolicy.allowInvalidCertificates = YES;
NSString *URLString = [NSString stringWithFormat:#"%#login", BASE_URL_STRING];
NSDictionary *params = #{#"email": user.username,
#"password": user.password};
[manager POST:URLString parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
responseBlock(nil, FALSE, error);
}];
}
I hope it helps.
How do I send a POST request with AFNetworking 2.0 with all the parameters in the URL like such:
http://www.myserver.com?api_key=something&lat=2.4&radius=100
Right now I have:
NSString* query = #"http://example.com?name=param&date=param";
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = #{};
[manager POST:query parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
But it's not working, I get this error back:
Error Domain=AFNetworkingErrorDomain Code=-1011 "Request failed: bad request (400)
The previous best answer was to get the backend to change and accepts parameters in the body. Thats the preferred method but sometimes some of us are stuck using backends that can't change so I offer this solution....
In the class AFURLRequestSerialization there is a property called HTTPMethodsEncodingParametersInURI and that is an NSSet that contains the http methods that are allowed to use params in the uri GET, HEAD, and DELETE by default.
You could override that and include POST as well.
in AFURLRequestSerialization.m lines 462 has an if statement that checks self.HTTPMethodsEncodingParametersInURI property contains POST. if it doesn't (as it doesn't by default), it will put the parameters in the body.
You can comment out that id statement for a quick test.
To get it to work I recommend overwriting the HTTPMethodsEncodingParametersInURI property.
when setting up your AFHTTPSessionManager it should look like this...
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:self.httpBaseUrl]];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.requestSerializer.HTTPMethodsEncodingParametersInURI = [NSSet setWithArray:#[#"POST", #"GET", #"HEAD", whatever other http methods you need here....]];
this should allow for sending a parameters in the uri of a POST. worked for me, hope it helps someone else

I've had the same problem with you.
Other people's answers seem to be accurate.
The cause of the error is:
when you init NSUrl with parameters such as http:www.baidu.com/api?id=1&name=我,it needs you to encode your urlString with utf-8
such as :
//解决奇葩需求：请求方式为post时，url带?id=1之类。主要原因是url带中文的时候url初始化失败
URLString = [URLString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *request = [self.requestSerializer requestWithMethod:method URLString:[[NSURL URLWithString:URLString relativeToURL:self.baseURL] absoluteString] parameters:parameters error:&serializationError];
Hope to help you!
can you try this.
NSString* apiURL = #"http://example.com"
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:apiURL]];
manager.responseSerializer = [AFJSONResponseSerializer serilizer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"application/json"];
NSDictionary *parameters = #{#"name":#"John",#"date":"27/12/2013"};
AFHTTPRequestOperation *apiRequest = [manager POST:#"" parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog#"response ---%#,responseObject";
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
}];
[apiRequest start];
I was able to do this by creating the string like this:
NSString *relativeURL =[NSString
stringWithFormat:#"/reward/commit?deviceUUID=%#&rewardID=%#",[[Client
sharedInstance] deviceUUID],self.rewardID];
and then passing it as the query. I had to set the requestSerializer and responseSerializer as follows:
client.requestSerializer = [AFJSONRequestSerializer serializer];
client.responseSerializer = [AFHTTPResponseSerializer serializer];
Worked for me once I left the manager.requestSerializer property alone and let it be the default (AFHTTPRequestSerializer).
The service i was POSTing to, was seemingly expecting UTF8 encoded body parameters.
