【问题描述】：

我正在尝试使用名为“#load”的操作参数进行 POST。

对我的网络服务来说，关键是需要显示结果：action:#load

如何使用 AFNetworking 框架做到这一点？这是我的错误代码示例：

首先是常量声明：

const NSString *BASE_URL = @"http://www.mywebservice.com/request.php";

现在是代码：

-(void)requisitarEventos
  [smartEventos removeAllObjects];

  NSString* url = [BASE_URL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

  AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
  [SVProgressHUD showWithStatus:@"Loading..." maskType:SVProgressHUDMaskTypeGradient];

  NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:@"#load",@"action", nil];

  [manager POST:url parameters:parameters
     success:^(AFHTTPRequestOperation *operation, id responseObject) 

         [self carregarEventos:responseObject];
         [SVProgressHUD dismiss];
     
     failure:^(AFHTTPRequestOperation *operation, NSError *error) 
         NSLog(@"Error: %@", error);
         [SVProgressHUD dismiss];
     ];
 

【参考方案1】：

我找到了答案。我的 Web 服务代码的真正问题不是在“application/json”中给出 Content-Type 的结果，而是在“text/html”中给出。

我使用下面的代码解决了这个问题：

NSMutableSet *contentTypes = [[NSMutableSet alloc] initWithSet:manager.responseSerializer.acceptableContentTypes];
[contentTypes addObject:@"text/html"];
manager.responseSerializer.acceptableContentTypes = contentTypes;

还有我班级的完整代码：

-(void)callEvents
[smartEvents removeAllObjects];

NSString* url = [NSString stringWithFormat:@"[e-mail]?action=load", BASE_URL];
url = [url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

[SVProgressHUD showWithStatus:@"Loading..." maskType:SVProgressHUDMaskTypeGradient];

manager.responseSerializer = [AFJSONResponseSerializer serializer];

NSMutableSet *contentTypes = [[NSMutableSet alloc] initWithSet:manager.responseSerializer.acceptableContentTypes];
[contentTypes addObject:@"text/html"];
manager.responseSerializer.acceptableContentTypes = contentTypes;

[manager GET:url parameters:nil
     success:^(AFHTTPRequestOperation *operation, id responseObject) 

         [self carregarEventos:responseObject];
         [SVProgressHUD dismiss];
     
     failure:^(AFHTTPRequestOperation *operation, NSError *error) 
         NSLog(@"Error: %@", error);
         [SVProgressHUD dismiss];
     ];

请看这个，我用回调做了一个简单的post方法，
