使用AFNetworking检索JSON的问题

我正在尝试使用AFNetworking检索一些JSON数据.

我的服务器组件(PHP/ZendFramework)提供以下响应:

>curl -i http://test.local:8080/public/appapi/testaction/format/json
HTTP/1.1 200 OK
Date: Mon, 06 Feb 2012 10:37:20 GMT
Server: Apache
X-Powered-By: PHP/5.3.8
Content-Length: 35
Content-Type: application/json
{"entries":"test","abcxxx":"test2"}

我尝试使用以下代码来检索此json数据:

NSString *baseurl = @"http://test.local:8080";

NSString *path = @"/public/appapi/testaction/format/json";

AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:baseurl]];
[client registerHTTPOperationClass:[AFJSONRequestOperation class]];
[client setAuthorizationHeaderWithUsername:@"myusername" password:@"mypassword"];

[client getPath:path parameters:nil success:^(__unused AFHTTPRequestOperation *operation, id JSON) {

    //NSLog(@"sjson: %@", [JSON valueForKeyPath:@"entries"]);
    NSLog(@"sjson: %@", JSON);        
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error Code: %i - %@",[error code], [error localizedDescription]);
}];
