【中文标题】NSLocalizedDescription=（200-299）中的预期状态码，得到 422【英文标题】：NSLocalizedDescription=Expected status code in (200-299), got 422 【发布时间】：2015-03-03 21:14:15 【问题描述】：我正在尝试发布广告。我按照我认为正确的方式设置了所有内容，但是当我单击玻色子“地籍 anuncio”时，它返回此错误“得到 422”。已经研究过该错误，但根本无法修复。 这里有人经历过吗？
这是我的网络服务

这是来自服务器日志的详细信息
在 2015-03-03 18:06:15 -0300 为 127.0.0.1 开始 POST "/ads.json" AdsController#create 作为 JSON 参数处理： "ad"=>"description"=>"ewewe", "id"=>"", "local"=>"ew", "price"=>"25", "title"=>"titulp" 用户负载 (0.6ms) SELECT users.* FROM users WHERE users.id = 2 ORDER BY users.id ASC LIMIT 1 不允许的参数：id (0.2ms) BEGIN (0.6ms) ROLLBACK Completed 10 毫秒内出现 422 个无法处理的实体（查看次数：0.3 毫秒 | ActiveRecord：1.4 毫秒）
【问题讨论】：
422 表示您的数据在某些方面不正确 - 您应该检查您的服务器日志以查看是否有更多信息可用。也许密码不符合复杂性要求？ 我没有添加使用密码的对象。我正在注册一个包含描述和价格标题的简单公告。作为销售申请编号。我在注册用户时使用了类似的方法。我认为这是问题，但似乎没有找到解决方法。 对不起，我没有意识到 - 你已经发布了很多代码 - 我看到了第一个发布操作是用户。将来最好将您的问题简化为仅包含 相关 代码，但是我的建议仍然有效 - 422 表示服务器对您发送的数据不满意。您需要检查您发送的值并在服务器日志中查找更多详细信息 于 2015-03-03 18:06:15 -0300 开始 POST "/ads.json" for 127.0.0.1 由 AdsController#create 作为 JSON 参数处理："ad"=>" description"=>"ewewe", "id"=>"", "local"=>"ew", "price"=>"25", "title"=>"titulp" 用户负载 (0.6ms) SELECTusers.* FROM users WHERE users.id = 2 ORDER BY users.id ASC LIMIT 1 不允许的参数：id (0.2ms) BEGIN (0.6ms) ROLLBACK Completed 422 Unprocessable在 10 毫秒内（查看：0.3 毫秒 | ActiveRecord：1.4 毫秒）
这是来自服务器的响应。你能理解吗？到目前为止，我能理解的内容对我没有多大帮助。
【参考方案1】：
状态码 422 表示您的数据在某些方面不正确 - 请求格式正确，但无法处理数据。
从服务器查看日志可以看到id是空的并且有错误信息Unpermitted parameters: id
您需要在发送请求之前确定 id 为空的原因并更正此问题。
