搜索文档并尝试一些代码后，我以以下示例为例
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];manager.requestSerializer = [AFJSonRequestSerializer serializer];NSDictionary *params = @ {@"user" :txtUserName, @"pwd" :txtPwd };[manager POST:URL_SIGNIN parameters:paramssuccess:^(AFHTTPRequestOperation *operation, id responseObject){ NSLog(@"JSON: %@", responseObject);}failure: ^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error); }];同样不要忘记在服务器脚本中将响应头类型设置为Application / json。
