AFNetworking Post Anfrage


81

Ich bin ein Neuling in obj-c und habe asihttp für einige meiner Projekte verwendet. Wenn Sie eine Post-Anfrage in asihttp ausführen, geschieht dies auf diese Weise.

    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
    [request setPostValue:height forKey:@"user[height]"];
    [request setPostValue:weight forKey:@"user[weight]"];
    [request setDelegate:self];
    [request startAsynchronous];

Wie würde AFNetworking mit einem Codebeispiel funktionieren?
Ich habe bereits die get Json getrequest in AFNetworking zum Laufen gebracht, aber diese Post-Anfrage gibt mir einige Probleme. Vielen Dank für Ihre Hilfe im Voraus.

Es lohnt sich zunächst hinzuzufügen (da diese Antwort 6 Jahre nach meinem ersten Schreiben immer noch beliebt ist ...), dass Sie als Erstes überlegen sollten, ob Sie AFNetworking überhaupt verwenden sollten. NSURLSession wurde in iOS 7 hinzugefügt und bedeutet, dass Sie in vielen Fällen kein AFNetworking verwenden müssen - und eine Bibliothek von Drittanbietern weniger ist immer eine gute Sache.

Für 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);
}];

Für AFNetworking 2.0 (und auch unter Verwendung der neuen 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);
}];

Wenn Sie mit AFNetworking 1.0 nicht weiterkommen, müssen Sie dies folgendermaßen tun:

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);
}];

Vielen Dank Joseph, es hat sehr gut funktioniert. Ich hatte gerade eine Frage, nachdem ich den httpClient zugewiesen habe, den ich nach dem Erstellen der Anfrage freigegeben habe. Ich habe anscheinend keine Abstürze und scheint gut zu funktionieren. Ich wollte nur bestätigen, dass dies der richtige Ort ist, um es freizugeben. Danke dir nochmal. Freundliche Grüße

Ja, das würde funktionieren. Der AFHTTPClient soll wirklich beibehalten und erneut verwendet werden, wenn Sie eine andere Anfrage stellen. Es ist jedoch akzeptabel, ihn direkt nach dem Aufruf von 'requestWithMethod:' freizugeben.

Hallo Joseph, ich habe es endlich mit einer json-Antwort zum Laufen gebracht und eine weitere Frage gestapelt stackoverflow.com/questions/7630289/…, um wirklich zu wissen, ob ich es richtig mache. Vielen Dank, dass Sie sich die Mühe gemacht haben.

Inzwischen scheint es keine "operationWithRequest: Completion" -Methode mehr für AFHTTPRequestOperation zu geben. Verwenden Sie einfach "initWithRequest" und dann "setCompletionBlockWithSuccess".

@ Rakesh Es ist schwierig, eine solche Frage in Kommentaren richtig zu beantworten - kann ich vorschlagen, dass Sie bitte eine neue Frage öffnen?

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]);
}];

Hier ist ein einfacher AFNetworking-POST, den ich verwende. Um nach dem Lesen des AFNetworking-Dokuments, des Wkiki, des Refs usw. den Betrieb aufzunehmen, habe ich viel gelernt, indem ich http://nsscreencast.com/episodes/6-afnetworking gefolgt bin und das zugehörige Codebeispiel auf Github verstanden habe.

 // 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;
      }
   ];  

Wird das responseObject automatisch in JSON analysiert?

    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);

    }];

Hoffe das funktioniert.

Hier ein Beispiel mit 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)")
}

Für AFNetworking 3.0 und Swift. Vielleicht können wir so verwenden:

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)
}

Hoffe, dies wird anderen helfen, eine Antwort wie ich zu finden!

Für AFNetworking 3.0 ( iOS9 oder 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);

                NSLog(@"responce:%@",aMutDict)

            });
        }
        else
        {
            dispatch_async(dispatch_get_main_queue(), ^{
                NSLog(@"error:%@",error.locali)
            });
        }
    }];

    [postDataTask resume];

und Hinzufügen

-(NSString *)getFormDataStringWithDictParams:(NSDictionary *)aDict
{
    NSMutableString *aMutStr = [[NSMutableString alloc]initWithString:@""];
    for (NSString *aKey in aDict.allKeys) {
        [aMutStr appendFormat:@"%@=%@&",aKey,aDict[aKey]];
    }
    NSString *aStrParam;
    if (aMutStr.length>2) {
        aStrParam = [aMutStr substringWithRange:NSMakeRange(0, aMutStr.length-1)];

    }
    else
        aStrParam = @"";

    return aStrParam;
}

Dieser Code verwendet AFNetworking überhaupt nicht. Dies ist nur ein Beispiel für die Verwendung von NSURLSession.

Mit AFNetworking 3.0 sollten Sie schreiben:

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);
    
}];

Das sieht gut aus, aber ich denke, OP hat nach einer Möglichkeit gesucht, eine POST-Anfrage zu senden.
