可可错误 3840

Question

我正在尝试使用AFNetworking 2.0 向服务器发送发布请求

NSDictionary * dict = @{@"credentials": @{
                                @"name": @"Valod",
                                @"password": @"test"
                                }
                        };

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];

[manager POST:URL parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];`

但我得到了错误

Error Domain=NSCocoaErrorDomain Code=3840 “操作无法完成。（Cocoa 错误 3840。）”（字符 0 周围的值无效。） UserInfo=0x7fd6214a5d70 {NSDebugDescription=字符 0 周围的值无效，NSUnderlyingError=0x7fd62150ec60 “请求失败：内部服务器错误 (500)”}

我用谷歌应用测试api调用。响应json is valid json

检查您的 requestSerializer，可能是 AFHTTPRequestSerializer 而不是 AFJSONRequestSerializer。 尝试设置manager.requestSerializer = [AFJSONRequestSerializer serializer];
