AFNetworkingポストリクエスト


82

私はobj-cの初心者で、いくつかのプロジェクトでasihttpを使用しています。asihttpでPOSTリクエストを実行する場合、この方法で実行されます。

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

これを行うには、コード例を使用したAFNetworkingをどのように使用しますか?
私はすでにgetJson getrequestをAFNetworkingで機能させていますが、この投稿リクエストは私にいくつかの問題を与えています。よろしくお願いします。

最初に追加する価値があるのは(この回答は最初に書いた後6年経ってもまだ人気があるので...)、最初に考慮すべきことは、AFNetworkingを使用する必要があるかどうかです。NSURLSessionはiOS7で追加されたため、多くの場合AFNetworkingを使用する必要はありません。サードパーティのライブラリが1つ少ないことは常に良いことです。

AFNetworking 3.0の場合:

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);
}];

AFNetworking 2.0の場合(および新しいNSDictionary構文を使用する場合):

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);
}];

AFNetworking 1.0の使用に行き詰まっている場合は、次のようにする必要があります。

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);
}];

ジョセフ、ありがとうございました。とてもうまくいきました。リクエストの作成後にリリースしたhttpClientを割り当てた後、質問がありました。クラッシュは発生しておらず、正常に機能しているようです。それがリリースするのに正しい場所であることを確認したかっただけです。どうもありがとうございました。よろしく

はい、それはうまくいくでしょう。AFHTTPClientは、実際には保持され、別の要求を行った場合に再度使用されることを目的としていますが、「requestWithMethod:」呼び出しの直後に解放することは許容されます。

こんにちはジョセフ、私はついにそれをjson応答で動作させ、別の質問stackoverflow.com/questions/7630289/を設定しました…私がそれを正しく行っているかどうかを本当に知るために。ご迷惑をおかけして誠にありがとうございます。

今では、AFHTTPRequestOperationの「operationWithRequest:completion」メソッドはもうないようです...「initWithRequest」を使用してから「setCompletionBlockWithSuccess」を使用するだけです。

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]);

これが私が使用している簡単なAFNetworkingPOSTです。AFNetworkingドキュメント、wkiki、REFなどを読んだ後起動して実行するために、私は次のことで多くのことを学んhttp://nsscreencast.com/episodes/6-afnetworkingをし、githubの上の関連するコードサンプルを理解します。

 // 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;
      }
   ];  

responseObjectは自動的にJSONに解析されますか?

    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);

    }];

これがうまくいくことを願っています。

AFNetworking4の場合

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);
}];

manager.requestSerializer = AFJSONRequestSerializer()
manager.requestSerializer.setValue("application/json", forHTTPHeaderField: "Content-Type")

    if var jsonResponse = responseObject as? [String: AnyObject] {
        // here read response
    }

AFNetworking3.0およびSwiftの場合。たぶん私たちはこのように使うことができます:

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)
}

これが私のような他の人が答えを見つけるのに役立つことを願っています!

AFNetworking 3.0の場合iOS9または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];

と追加

-(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;
}

そのコードはAFNetworkingをまったく使用していません。これは、NSURLSessionの使用方法の一例にすぎません。

AFNetworking 3.0を使用して、次のように記述します。

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);
    
}];

これは良さそうですが、OPはPOSTリクエストを送信する方法を探していたと思います。
