AFNetworking Post Request - ios

Question

I'm a newbie in obj-c and have been using asihttp for some of my projects. When doing a post request in asihttp its done this way.
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:height forKey:#"user[height]"];
[request setPostValue:weight forKey:#"user[weight]"];
[request setDelegate:self];
[request startAsynchronous];
How would go about doing this is AFNetworking with a code example ?
I already got the get Json getrequest working in AFNetworking but this post request is giving me some problems. Thanks for help in advance.

Answer 1

It's first worth adding (as this answer is still popular 6 years after I initially wrote it...) that the first thing you should consider is whether you should even use AFNetworking. NSURLSession was added in iOS 7 and means you don't need to use AFNetworking in many cases - and one less third party library is always a good thing.
For AFNetworking 3.0:
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSDictionary *params = #{#"user[height]": height,
#"user[weight]": weight};
[manager POST:#"https://example.com/myobject" parameters:params progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
For AFNetworking 2.0 (and also using the new NSDictionary syntax):
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = #{#"user[height]": height,
#"user[weight]": weight};
[manager POST:#"https://example.com/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
If you are stuck using AFNetworking 1.0, you need to do it this way:
NSURL *url = [NSURL URLWithString:#"https://example.com/"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
height, #"user[height]",
weight, #"user[weight]",
nil];
[httpClient postPath:#"/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *responseStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(#"Request Successful, response '%#'", responseStr);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"[HTTPClient Error]: %#", error.localizedDescription);
}];

Answer 2

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
height, #"user[height]",
weight, #"user[weight]",
nil];
AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:
[NSURL URLWithString:#"http://localhost:8080/"]];
[client postPath:#"/mypage.php" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *text = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(#"Response: %#", text);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"%#", [error localizedDescription]);
}];

Answer 3

Here is a simple AFNetworking POST I'm using. To get up and running after
reading the AFNetworking doc, wkiki, ref, etc, I learned a lot by
following http://nsscreencast.com/episodes/6-afnetworking and understanding
the associated code sample on github.
// Add this to the class you're working with - (id)init {}
_netInst = [MyApiClient sharedAFNetworkInstance];
// build the dictionary that AFNetworkng converts to a json object on the next line
// params = {"user":{"email":emailAddress,"password":password}};
NSDictionary *parameters =[NSDictionary dictionaryWithObjectsAndKeys:
userName, #"email", password, #"password", nil];
NSDictionary *params =[NSDictionary dictionaryWithObjectsAndKeys:
parameters, #"user", nil];
[_netInst postPath: #"users/login.json" parameters:params
success:^(AFHTTPRequestOperation *operation, id jsonResponse) {
NSLog (#"SUCCESS");
// jsonResponse = {"user":{"accessId":1234,"securityKey":"abc123"}};
_accessId = [jsonResponse valueForKeyPath:#"user.accessid"];
_securityKey = [jsonResponse valueForKeyPath:#"user.securitykey"];
return SUCCESS;
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"FAILED");
// handle failure
return error;
}
];

Answer 4

For AFNetworking 4
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSDictionary *params = #{#"user[height]": height,
#"user[weight]": weight};
[manager POST:#"https://example.com/myobject" parameters:params headers:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];

Answer 5

AFHTTPClient * Client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:#"http://urlname"]];
NSDictionary * parameters = [[NSMutableDictionary alloc] init];
parameters = [NSDictionary dictionaryWithObjectsAndKeys:
height, #"user[height]",
weight, #"user[weight]",
nil];
[Client setParameterEncoding:AFJSONParameterEncoding];
[Client postPath:#"users/login.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"operation hasAcceptableStatusCode: %d", [operation.response statusCode]);
NSLog(#"response string: %# ", operation.responseString);
NSDictionary *jsonResponseDict = [operation.responseString JSONValue];
if ([[jsonResponseDict objectForKey:#"responseBody"] isKindOfClass:[NSMutableDictionary class]]) {
NSMutableDictionary *responseBody = [jsonResponseDict objectForKey:#"responseBody"];
//get the response here
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"error: %#", operation.responseString);
NSLog(#"%d",operation.response.statusCode);
}];
Hope this works.

Here an example with Swift 3.0
let manager = AFHTTPSessionManager(sessionConfiguration: URLSessionConfiguration.default)
manager.requestSerializer = AFJSONRequestSerializer()
manager.requestSerializer.setValue("application/json", forHTTPHeaderField: "Content-Type")
manager.requestSerializer.setValue("application/json", forHTTPHeaderField: "Accept")
if authenticated {
if let user = UserDAO.currentUser() {
manager.requestSerializer.setValue("Authorization", forHTTPHeaderField: user.headerForAuthentication())
}
}
manager.post(url, parameters: parameters, progress: nil, success: { (task: URLSessionDataTask, responseObject: Any?) in
if var jsonResponse = responseObject as? [String: AnyObject] {
// here read response
}
}) { (task: URLSessionDataTask?, error: Error) in
print("POST fails with error \(error)")
}

Answer 8

For AFNetworking 3.0 and Swift. Maybe we can use like this:
let configutation = NSURLSessionConfiguration.defaultSessionConfiguration()
manager = AFHTTPSessionManager(sessionConfiguration: configutation)
let urlString = "url"
manager.POST(urlString, parameters: [params here], progress: nil, success: { (dataTask: NSURLSessionDataTask, response: AnyObject?) -> Void in
print(dataTask)
print(response)
}) { (dataTask: NSURLSessionDataTask?, error: NSError) -> Void in
print(error)
}
Hope this will help other find answer like me!

For AFNetworking 3.0 (iOS9 or greter)
NSString *strURL = #"https://exampleWeb.com/webserviceOBJ";
NSDictionary *dictParamiters = #{#"user[height]": height,#"user[weight]": weight};
NSString *aStrParams = [self getFormDataStringWithDictParams:dictParamiters];
NSData *aData = [aStrParams dataUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *aRequest = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:strURL]];
[aRequest setHTTPMethod:#"POST"];
[aRequest setHTTPBody:aData];
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:nil delegateQueue:nil];
[aRequest setHTTPBody:aData];
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:aRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
//
if (error ==nil) {
NSString *aStr = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"ResponseString:%#",aStr);
NSMutableDictionary *aMutDict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
dispatch_async(dispatch_get_main_queue(), ^{
completionBlock(aMutDict);

});
}
else
{
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(#"error:%#",error.locali)
});
}
}];
[postDataTask resume];
and Add
-(NSString *)getFormDataStringWithDictParams:(NSDictionary *)aDict
{
NSMutableString *aMutStr = [[NSMutableString alloc]initWithString:#""];
for (NSString *aKey in aDict.allKeys) {
[aMutStr appendFormat:#"%#=%#&",aKey,aDict[aKey]];

if (aMutStr.length>2) {
aStrParam = [aMutStr substringWithRange:NSMakeRange(0, aMutStr.length-1)];
}
else
aStrParam = #"";
return aStrParam;

Answer 15

Using AFNetworking 3.0, you should write:
NSString *strURL = #"https://exampleWeb.com/webserviceOBJ";
NSURL * urlStr = [NSURL URLWithString:strURL];
NSDictionary *dictParameters = #{#"user[height]": height,#"user[weight]": weight};
AFHTTPSessionManager * manager = [AFHTTPSessionManager manager];
[manager POST:url.absoluteString parameters:dictParameters success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"PLIST: %#", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
