我在 Rails 中看到一个奇怪的问题。

请求正文（request.body）：

renewals[][driver_1][expiration_date]=20130513&
renewals[][driver_1][last_name]=123&
renewals[][driver_1][state]=AL&

JSON 解析参数（params[:renewals]）：https ://gist.github.com/t2/5566652

请注意，在 JSON 中，最后一条记录中缺少 driver_1 信息。不知道为什么会这样。数据在请求中。我缺少任何已知的错误吗？如果您需要更多信息，请告诉我。

不幸的是，这正是 Rails 解析 JSON 的方式（你[]的嵌套很大）。我之前遇到过这个问题 - http://guides.rubyonrails.org/form_helpers.html#combining-them给出了一些解释。

据我记得，如果您可以输入数字键而不仅仅是[]（即[1]第一个，[2]第二个等），那么它将按您的意愿工作。

所以我想通了。我需要设置requestSerializationMIMEType为RKMIMETypeJSON.
