我需要asp.net应用程序的正则表达式匹配至少6个字符长的字母数字字符串.

我正在尝试使用 activerecord 导入进行导入。我收到无效参数错误我该如何解决这个问题？

谢谢

我在 postgresql 中的表架构：

create_table "vehicle_locations", force: :cascade do |t|
t.string "plate"
t.datetime "timestamp"
t.float "latitude"
t.float "longitude"
t.integer "speed"
t.integer "mileage"
t.boolean "ignition_on"
t.string "address"
end

我正在尝试使用以下代码导入：

values = [{"plate":"xxx","timestamp":"2017-11-28 
 20:42:57","latitude":41.9322,"longitude":27.3253,"speed":0,"mileage":1984
 04,"ignition_on":true,"address":"address"},{"plate":"xxx","timestamp":"2017-11-28 20:43:46","latitude":47.0148,"longitude":39.1805,"speed":16,"mileage":209726,"ignition_on":true,"address":"address"}]

   columns = [:plate, :timestamp, :latitude, :longitude, :speed, :mileage, :ignition_on,  :address ]
  VehicleLocation.import columns, values

我正在使用 postgresql、rails 5.1。

提前致谢。

我正在使用microsoft anti xss库来形成安全性.我正在使用HtmlFormUrlEncode方法.

如何解码录制的数据？

样本数据 :

mail%40sample.com
%c3%96nder  

我试图在C++中连接两个字符串:

"G1-2" + "-%02d.jpg"

我得到以下结果:

G1-2-1537817269.jpg

为什么不是这样的结果: "G1-2-%02d.jpg"
