如何通過AFNetworking做GET請求？

我向項目經理添加了目錄AFNetworking和UIKit+AFNetworking。我使用最新庫3.0.4如何通過AFNetworking做GET請求？

我導入文件AFNetworking.h在我的課文件.m。我發現了很多示例如何向url發送請求，但信息已老化。

如何讓GET請求到URL並從服務器獲取數據？現在函數AFHTTPRequestOperation已被刪除。

這是第一次在xcode中使用庫，我是初學者。

你不需要爲第三方庫，檢查NSURLSession。 –

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"http://google.com/"]]; 
NSMutableURLRequest *request = [httpClient requestWithMethod:@"GET" 
                 path:@"http://google.com/api/pigs/" 
                parameters:nil]; 

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; 

[httpClient registerHTTPOperationClass:[AFHTTPRequestOperation class]]; 

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { 

    // Print the response body in text 
    NSLog(@"Response: %@", [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]); 

} failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
    NSLog(@"Error: %@", error); 
}]; 
[operation start];

=========================================== ==

您還可以使用AFHTTPRequestOperation：

NSOperationQueue *networkQueue = [[NSOperationQueue alloc] init]; 

networkQueue.maxConcurrentOperationCount = 5; 

NSURL *url = [NSURL URLWithString:@"https://example.com"]; 

NSURLRequest *request = [NSURLRequest requestWithURL:url]; 

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] 
initWithRequest:request]; 

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { 


    NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]; 

    NSLog(@"%@", string); 

} failure:^(AFHTTPRequestOperation *operation, NSError *error) { 

    NSLog(@"%s: AFHTTPRequestOperation error: %@", __FUNCTION__, error); 
}]; 
[networkQueue addOperation:operation];

非常感謝，但不支持'AFHTTPRequestOperation' – Oleg

您是否只使用'#import「AFNetworking.h」'？ Compilator沒有看到對象'AFHTTTPClient' – Oleg

注意這個解決方案在AFNetworking 3.0中不起作用，請參閱下面的Chanchal對於工作片段的回答。 – Tiago

隨着AFNetworking 3.0你需要請求作爲下：

NSURL * urlStr = [NSURL URLWithString:strURL]; 

NSDictionary *dictParameters = @{@"user[height]": height,@"user[weight]": weight}; 

AFHTTPSessionManager * manager = [AFHTTPSessionManager manager]; 


[manager GET:url.absoluteString parameters:dictParameters success:^(NSURLSessionTask *task, id responseObject) { 
    NSLog(@"PLIST: %@", responseObject); 

} failure:^(NSURLSessionTask *operation, NSError *error) { 
    NSLog(@"Error: %@", error); 

}];

對於AFNetworking 3.X：

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; 
[manager GET:@"http://example.com/resources.json" parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) { 
    NSLog(@"JSON: %@", responseObject); 
} failure:^(NSURLSessionTask *operation, NSError *error) { 
    NSLog(@"Error: %@", error); 
}];

作爲提問者談論AFNetworking 3.0+的最佳答案。 AFNetworking 3.0不再支持上述其他解決方案。 – AndaluZ

這應該是接受的答案！ – armnotstrong

(void)postDatabyAF{ 

NSString *url; 

NSDictionary *dict; 

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 

manager.responseSerializer = [AFJSONResponseSerializer serializer]; 

manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions: 
           NSJSONReadingAllowFragments]; 

[manager POST:url parameters:dict success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) { 

    NSLog(@" operation.responseData %@",operation.responseData); 
    NSLog(@" operation.response %@",operation.response); 
    NSLog(@"statusCode %ld",operation.response.statusCode); 

} failure:^(AFHTTPRequestOperation * _Nullable operation, NSError * _Nonnull error) { 

    if (error) { 

    } 
    else{ 


    } 
}];

please try below answer. 
+(void)callAFWS:(NSDictionary *)dict withURL:(NSString *)strUrl 
withToken:(NSString *)strToken withBlock:(dictionary)block 
{ 
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; 

[manager.requestSerializer setValue:strToken forHTTPHeaderField:@"Authorization"]; 

[manager GET:[NSString stringWithFormat:@"%@/%@",WebserviceUrl,strUrl] parameters:dict progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { 
    if (!responseObject) 
    { 
     NSMutableDictionary *dict = [[NSMutableDictionary alloc] init]; 
     [dict setObject:ServerResponceError forKey:@"error"]; 
     block(responseObject); 
     return ; 
    } 
    block(responseObject); 
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { 
    NSMutableDictionary *dict = [[NSMutableDictionary alloc] init]; 
    [dict setObject:ServerResponceError forKey:@"error"]; 
    block(dict); 
}]; 
}
