Iphone 如何使用AFNetworking连接网站

对不起，我是初学者。 如何使用AFNetworking连接网站：

我要做的是：

{
              "method": "authorize",
              "params": [
                "100000202",
                "TestApp677"`
              ]
            }

到端点：

我阅读了《开始指南》并添加了库，但我不知道如何开始

我有：

NSURL *url = [NSURL URLWithString:@"http://qqqqq.com/mobileapi/authorize/?ver=2_01"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:url];
    [client registerHTTPOperationClass:[AFJSONRequestOperation class]];
    [client setAuthorizationHeaderWithUsername:@"xxx" password:@"yyy"];

接下来呢

更新

当我使用来自Jano的代码时，我得到以下错误：

<code>
Error Domain=com.alamofire.networking.error Code=-1016 "Expected content type {(
    "text/json",
    "application/json",
    "text/javascript"
)}, got text/html" UserInfo=0x6875ce0<br> {NSErrorFailingURLKey=http://qqqqq.com/authorize/?ver=2_01,
NSLocalizedDescription=Expected content type {(
    "text/json",
    "application/json",
    "text/javascript"
)}, got text/html}

URLWithString:@]]

及

我得到一个错误：

Error Domain=com.alamofire.networking.error Code=-1011 "Expected status code in (200-299), got
 404" UserInfo=0x68562b0 {NSErrorFailingURLKey=http://qqqqq.com/authorize/?ver=2_01, 
NSLocalizedDescription=Expected status code in (200-299), got 404}

更新

我的代码如下所示：

 <code>NSMutableDictionary *jsonDic = [NSMutableDictionary dictionary];
        [jsonDic setObject:@"authorize" forKey:@"method"];
        [jsonDic setObject:[NSArray arrayWithObjects:@"100000202",@"TestApp677", nil] forKey:@"params"];

        AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"http://xxxxx.com"]];
        [client registerHTTPOperationClass:[AFJSONRequestOperation class]];
        [client setAuthorizationHeaderWithUsername:@"mobileapi" password:@"M031leA#p1"];

        NSMutableURLRequest *request = [client requestWithMethod:@"POST" path:@"/mobileapi/authorize/?ver=2_01" parameters:jsonDic];

    [client setParameterEncoding:AFJSONParameterEncoding];

    [AFJSONRequestOperation addAcceptableContentTypes:[NSSet setWithObject:@"text/html"]];

    AFJSONRequestOperation *operation = [AFJSONRequestOperation
                                         JSONRequestOperationWithRequest:request
                                         success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON){
                                             NSLog(@"%@",JSON);
                                         }
                                         failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
                                             NSLog(@"%@",error);
                                         }];
    [client enqueueHTTPRequestOperation:operation];</code>

and i get error:

Error Domain=JKErrorDomain Code=-1 "Unexpected token, wanted '{', '}', '[', ']', ',', ':', 'true', 'false', 'null', '"STRING"', 'NUMBER'." UserInfo=0x6d47460 {JKAtIndexKey=0, JKLineNumberKey=1, NSLocalizedDescription=Unexpected token, wanted '{', '}', '[', ']', ',', ':', 'true', 'false', 'null', '"STRING"', 'NUMBER'.}

<B>UPDATE</B>

----------

MY CODE IS A LOOK LIKE:

    NSString* encodeToPercentEscapeString(NSString *string) {
        return (NSString *)
        CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL,
                                                                  (__bridge CFStringRef) string,
                                                                  NULL,
                                                                  (CFStringRef) @"!*'();:@&=+$,/?%#[]",
                                                                  kCFStringEncodingUTF8));
    }

    - (void)viewDidLoad
    {
        //NSMutableDictionary *jsonDic = [NSMutableDictionary dictionary];
        //[jsonDic setObject:@"authorize" forKey:@"method"];
        //

[jsonDic setObject:[NSArray arrayWithObjects:@"100000202",@"TestApp677", nil] forKey:@"params"];


        NSDictionary *jsonDic = [NSString stringWithFormat:@"{\"method\":\"authorize\",\"params\":\[\"100000202\",\"TestApp\"]}",nil];


        NSLog(@"%@", jsonDic);

        NSString *password = encodeToPercentEscapeString(@"M031leA#p1");

        AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"http://vemmaeurope.com"]];
        [client registerHTTPOperationClass:[AFJSONRequestOperation class]];
        [client setAuthorizationHeaderWithUsername:@"mobileapi" password:password];


        NSMutableURLRequest *request = [client requestWithMethod:@"POST" path:@"/mobileapi/authorize/?ver=2_01" parameters:jsonDic];

        [client setParameterEncoding:AFJSONParameterEncoding];
        [AFJSONRequestOperation addAcceptableContentTypes:[NSSet setWithObject:@"text/html"]];

        AFJSONRequestOperation *operation = [AFJSONRequestOperation
                                             JSONRequestOperationWithRequest:request
                                             success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON){
                                                 NSLog(@"%@",JSON);
                                             }
                                             failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
                                                 NSLog(@"%@",error);
                                             }];
        [client enqueueHTTPRequestOperation:operation];


        // Do any additional setup after loading the view, typically from a nib.
    }

我仍然有同样的错误：

Error Domain=JKErrorDomain Code=-1 "Unexpected token, wanted '{', '}', '[', ']', ',', ':', 
'true', 'false', 'null', '"STRING"', 'NUMBER'." UserInfo=0x6c40cd0 {JKAtIndexKey=0, 
JKLineNumberKey=1, NSLocalizedDescription=Unexpected token, wanted '{', '}', '[', ']', ',', ':', 
'true', 'false', 'null', '"STRING"', 'NUMBER'.}

以下魔法可能会有所帮助：

NSMutableDictionary *jsonDic = [NSMutableDictionary dictionary];
[jsonDic setObject:@"authorize" forKey:@"method"];
[jsonDic setObject:[NSArray arrayWithObjects:@"100000202",@"TestApp677", nil] forKey:@"params"];

AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"http://qqqqq.com"]];
[client registerHTTPOperationClass:[AFJSONRequestOperation class]];
[client setAuthorizationHeaderWithUsername:@"xxx" password:@"yyy"];

NSMutableURLRequest *request = [client requestWithMethod:@"GET" path:@"/authorize/?ver=2_01" parameters:jsonDic];
AFJSONRequestOperation *operation = [AFJSONRequestOperation
                                     JSONRequestOperationWithRequest:request
                                     success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON){
                                         NSLog(@"%@",JSON);
                                     }
                                     failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
                                         NSLog(@"%@",error);
                                     }];
[client enqueueHTTPRequestOperation:operation];

如果GET不起作用，请将其替换为POST

更新

如果参数上有异常字符，例如：@M031leAp1将参数@M031leAp1替换为encodeToPercentEscapeString@M031leAp1然后将以下C函数粘贴到类中的任意位置：

// remove CFBridgingRelease and __bridge if your code is not ARC
NSString* encodeToPercentEscapeString(NSString *string) {
    return (NSString *)
        CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL,
                                            (__bridge CFStringRef) string,
                                            NULL,
                                            (CFStringRef) @"!*'();:@&=+$,/?%#[]",
                                            kCFStringEncodingUTF8));
}

你走了多远？你看过《入门指南》了吗？您是否已将库添加到应用程序中？你提出要求了吗？你被卡在哪一部分？是的，阅读开始指南，我添加了库，但我不知道如何开始。开始指南解释了如何开始。你在《起步指南》中走了多远？您被卡在了哪一位？我不知道如何添加查询。开始指南告诉您使用AFHTTPClient。是否已执行此操作？问题是服务器返回了错误的内容类型，如果无法在服务器上修复，则应在服务器上修复此问题。请尝试以下操作：[AFJSONRequestOperation addAcceptableContentTypes:[NSSet setWithObjects:@text/html，nil]我收到此错误：error Domain=JKErrorDomain Code=-1意外标记，需要“{'，”}，“['，”]“，”，“，”：“，”真“，”假“，”空“，”字符串“，”数字“.UserInfo=0x6d47460{JKAtIndexKey=0，JKLineNumberKey=1，NSLocalizedDescription=意外标记，需要“{'，”，”['，”，”：“，”真“，”假“，”空“，”字符串“，”数字“}”
