Question

我正在使用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", @"xxxxx@gmail.com", @"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]);
}];

，回复如下：

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 {

    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}

我不知道这个问题是什么。

在执行请求之前，您需要设置请求和响应序列化程序以使用AFJSONRequestSerializer和AFJSONResponseSerializer来处理JSON。为参数使用NSDictionary文字有助于提高代码清晰度：

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":   @"xxxxx@gmail.com",
                        @"password: @"xxxxx",
                        @"type":    @"1"}
               success:^(AFHTTPRequestOperation *operation, id responseObject) {
                   NSLog(@"JSON: %@", [responseObject description]);
               } 
               failure:^(AFHTTPRequestOperation *operation, NSError *error) {
                   NSLog(@"Error: %@", [error description]);
               }
];

解决我的问题，我的服务器没有配置为使用application / json接受charset utf8所以我刚刚删除了Afnetworking 2.0中ajson序列化程序的charset utf，现在它正在运行中。

使用AFHttpRequestOperationManager发布请求不起作用
