应用程序之间 JSON 的不同 NSMutableDictionary 格式

Question

好吧，这就是问题所在。我有两个应用程序需要打包 JSON 请求数据并将其发送到服务器。问题是，当我打印 NSMutableDictionary 的结果用作 JSON 请求正文时，我从不同的应用程序得到不同的结果。我以相同的方式格式化数据，但不明白为什么我得到不同的结果。可能是编译器设置？还是iOS版本？不确定此时要检查什么。

        requestDictionary = [[NSMutableDictionary alloc] init];

        // Set Lead type
        NSString *leadType = @"lead";
        [requestDictionary setObject:leadType forKey:@"type"];

我不明白为什么我会得到所有这些分号和括号，因为它们正在破坏我的 JSON 格式。我可以发布有效的方法（相同的过程，不同的应用程序），但真正的问题是为什么这种格式会关闭？

        [resultPerson setObject:m_phonetic forKey:@"field_lead_phonetic"];

    if(m_leadStatus)
        [resultPerson setObject:m_leadStatus forKey:@"field_lead_status"];

    NSLog(@"Resulting Person data: %@", resultPerson);

结果是：

{"status":"1","field_lead_first_name":[{"value":"2"}],"field_lead_zip":[{"value":""}],"field_lead_requested_assets":[{"nid":"19839"}],"field_lead_email":[{"value":"[email protected]"}],"type":"lead","field_lead_title":[{"value":"Programmer"}],"og_public":0,"field_lead_last_name":[{"value":"Sigsbey"}],"field_lead_city":[{"value":"Austin"}],"field_lead_source":[{"nid":"19323"}],"field_lead_phone_1":[{"value":"5129147975"}],"field_lead_company":[{"value":"Sparksight"}],"field_lead_state":[{"value":"Tx"}],"field_lead_add_1":[{"value":""}]}

Answer 1

正如评论所指出的，字典的 NSLog 不保证具有任何特定的格式。因此，它可能会在 iOS 版本之间发生变化。

您最好做的可能是：

• 将自己限制在 iOS 5 上并使用 Apple 的 NSJSONSerialization +dataWithJSONObject:options:error:;
• 使用第三方 JSON 库在任何版本的 iOS 上实现相同的功能；或者
• 根据您正在使用的对象子集编写您自己的输出器。

如果您构建字典只是为了转换为 JSON，您甚至可以考虑只构建 JSON 字符串而不是字典。

所以，事实证明这不是 JSON 解析或 NSDictionary 的设置。该问题最终与服务器相关（后端连接中断）。不管怎样，感谢所有的帮助！
