AFNetworking POST请求失败代码= -1011（400）

Question

我有一个网络服务，我可以通过Postman实用程序成功发布电话。在Postman上的设置是

我使用AFNetworking。这是我的代码：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{@"offset": @"1", @"csrf-token": @"63b164ea557b4aba694f81520c71972fa43a9772"};
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager POST:@"http://simple.com/" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

但是我收到了这个错误：

Error: Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: bad request (400)" UserInfo=0x7a6c5240 {com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x7a6b5360> { URL: http://simple.com/ } { status code: 400, headers {

    "Transfer-Encoding" = Identity;
    Vary = "Accept-Encoding,User-Agent";
    "X-Powered-By" = "PHP/5.5.17";

没有AFNetworking：

NSString *post = @"offset=1&csrf-token=63b164ea557b4aba694f81520c71972fa43a9772";
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];

NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:@"http://simple.com/"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded; charset=UTF-8" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];


NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

NSHTTPURLResponse *response = nil;
NSError *error = nil;
NSData *respData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(@"~~~~~ Status code: %d", [response statusCode]); 

又一次错误：400

请帮助解决问题

我解决了他的问题。

服务器使用特定的 CSRF令牌保持会话的事实。我的错误是我在浏览器和移动设备中使用了相同的令牌。因此，服务器并没有提供错误的POST请求的详细信息。

我的解决方案：我首先获得服务器 CSRF令牌，然后对于进一步的POST次查询，我使用了生成的令牌。为了响应POST请求，我得到状态200和我需要的数据。

True AFNetworking我在这个问题上没有真正的帮助，所以我不得不使用标准NSURLConnection（我把代码放在了问题中）。也许将来有人派上用场了！

感谢大家！祝大家好运！
