ios7 – 发送请求与AFHttpRequestOperationManager不工作

我使用AFHTTPRequestOperationManager将一些 JSON发布到我的服务器,我的代码如下.

NSDictionary *parameters = [[NSDictionary alloc] initWithObjectsAndKeys:@"john",@"name",@"[e-mail]",@"email",@"xxxx",@"password",@"1",@"type",nil];
// Do any additional setup after loading the view.
AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
[policy setAllowInvalidCertificates:YES];
AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
[operationManager setSecurityPolicy:policy];

[operationManager POST:@"posturl here" parameters:parameters success:^(AFHTTPRequestOperation *operation,id responseObject) {
    NSLog(@"JSON: %@",[responseObject description]);
} failure:^(AFHTTPRequestOperation *operation,NSError *error) {
    NSLog(@"Error: %@",[error description]);
}];

答复如下：

2013-11-18 16:49:29.780 SwapOnceApiTester[12651:60b] Error: Error Domain=AFNetworkingErrorDomain Code=-1011 "Request failed: unsupported media type (415),got 1664256" UserInfo=0x1565a6c0 {NSErrorFailingURLKey=xxxxxxx,AFNetworkingOperationFailingURLResponseErrorKey=<NSHTTPURLResponse: 0x15656db0> { URL: xxxxxxxxx } { status code: 415,headers {

    Date = "Mon,18 Nov 2013 11:49:28 GMT";
    Expires = "Mon,25 Nov 2013 11:49:28 GMT";
    Server = nginx;
    "Transfer-Encoding" = Identity;
    "X-Powered-By" = PleskLin;
} },NSLocalizedDescription=Request failed: unsupported media type (415),got 1664256}

我不知道这是什么问题.

解决方法

在执行您的请求之前,需要使用AFJSONRequestSerializer和AFJSONResponseSerializer设置请求和响应序列化程序来处理JSON.为您的参数使用NSDictionary文字帮助代码清晰度：

AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
[policy setAllowInvalidCertificates:YES];

AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
[operationManager setSecurityPolicy:policy];
operationManager.requestSerializer = [AFJSONRequestSerializer serializer];
operationManager.responseSerializer = [AFJSONResponseSerializer serializer];

[operationManager POST:@"posturl here" 
            parameters: @{@"name":  @"john",@"email":   @"[e-mail]",@"password: @"xxxxx",@"type":    @"1"}
               success:^(AFHTTPRequestOperation *operation,id responseObject) {
                   NSLog(@"JSON: %@",[responseObject description]);
               } 
               failure:^(AFHTTPRequestOperation *operation,NSError *error) {
                   NSLog(@"Error: %@",[error description]);
               }
];
