我正在尝试AFNetworking的新版本2.0,我得到上面的错误。知道为什么会这样吗?这是我的代码:

    NSURL *URL = [NSURL URLWithString:kJSONlink];
    NSURLRequest *request = [NSURLRequest requestWithURL:URL];
    AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    op.responseSerializer = [AFJSONResponseSerializer serializer];
    [op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"JSON: %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
    [[NSOperationQueue mainQueue] addOperation:op];

我使用的是Xcode 5.0。

另外,下面是错误消息:

Error: Error Domain=AFNetworkingErrorDomain Code=-1016 "Request failed: unacceptable content-type: text/html" UserInfo=0xda2e670 {NSErrorFailingURLKey=kJSONlink, AFNetworkingOperationFailingURLResponseErrorKey=<NSHTTPURLResponse: 0xda35180> { URL: kJSONlink } { status code: 200, headers {
    Connection = "Keep-Alive";
    "Content-Encoding" = gzip;
    "Content-Length" = 2898;
    "Content-Type" = "text/html";
    Date = "Tue, 01 Oct 2013 10:59:45 GMT";
    "Keep-Alive" = "timeout=5, max=100";
    Server = Apache;
    Vary = "Accept-Encoding";
} }, NSLocalizedDescription=Request failed: unacceptable content-type: text/html}

我只是使用kJSONlink隐藏了JSON。这应该返回一个JSON。

我把@jaytrixz的答案/评论更进一步,并将“text/html”添加到现有的类型集。这样,当他们在服务器端将其修复为“application/json”或“text/json”时,我声称它将无缝工作。

  manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];

在服务器端,我添加了:

header('Content-type: application/json');

到我的。php代码,这也解决了这个问题。

在我的情况下,我没有控制服务器设置,但我知道它期待“应用程序/json”为“内容类型”。我在iOS客户端是这样做的:

manager.requestSerializer = [AFJSONRequestSerializer serializer];

指 AFNetworking版本2内容类型错误

这是我发现的唯一有效的方法

-(void) testHTTPS {
    AFSecurityPolicy *securityPolicy = [[AFSecurityPolicy alloc] init];
    [securityPolicy setAllowInvalidCertificates:YES];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager setSecurityPolicy:securityPolicy];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

    [manager GET:[NSString stringWithFormat:@"%@", HOST] parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
        NSLog(@"%@", string);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
}
