如何使用Shell脚本将当前日期传递给curl查询？ [英] How to pass current date to a curl query using shell script?

问题描述

我正在使用CURL将数据插入弹性搜索，当我插入固定数据时，它可以正常工作。我试图获取当前DateTime并分配给变量，并与我要插入的对象一起使用。

I am inserting data to a elastic search using CURL, it works fine when i insert with a fixed data. I am trying to Get Current DateTime and assign to a variable and use with the object that i want to insert.

这是我的脚本，

while true;
do

echo $i

number=$RANDOM;
let "number %= 9";
let "number = number + 1";
range=10;
for i in {1..18}; do
  r=$RANDOM;
  let "r %= $range";
  number="$number""$r";
done;

curl -XPUT 'http://localhost:9200/nondomain_order/orders/'+$number+'' -d '{
  "CustType": null,
  "tag": "OrderType:Postpaid",
  "GUDeviceID": "0",
  "IsAvailable": false,
  "GUOrderID": "123",
  "OrderID": "3",
  "OrderDate": "2015-01-06T15:23:42.7198285+05:30",
  "GUAccountID": "15010615234251403",
  "CreateUser": "admin",
  "CreateDate": "2015-01-01T15:23:42",
  "CancelledDate": "1899-01-01T00:00:00",
  "CancelledUser": null,
  "GUTranID": "15010615234271604",
  "TenentID": 39,
  "CompanyID": 42,
  "ViewObjectID": 0,
  "ObjectID": null,
  "Status": 2,
  "OrderDetails": [
    {
      "GUPromtionID": "15010519341113508",
      "GUOrderID": "15010615234271703",
      "ChangeID": 0,
      "GUPackageID": "14100112243589402",
      "startdate": "2015-01-06T00:00:00" 
    }
]

我需要获取当前的DateTime d分配给CreateDate。我该怎么办？

I need to get the current DateTime and assign to the CreateDate. How can i do that?

推荐答案

与其建议不要在引号内使用引号，不建议使用 here-doc 摆脱所有魔术报价。像这样使用您的 curl ：

Rather than playing with quotes inside quotes I would suggest using here-doc to get rid of all magic quoting. Use your curl like this:

number=10
dt="$(date --iso-8601=seconds)"

curl -XPUT 'http://localhost:9200/nondomain_order/orders/'$number -d@- <<EOF
{
  "CustType": null,
  "tag": "OrderType:Postpaid",
  "GUDeviceID": "0",
  "IsAvailable": false,
  "GUOrderID": "123",
  "OrderID": "3",
  "OrderDate": "2015-01-06T15:23:42.7198285+05:30",
  "GUAccountID": "15010615234251403",
  "CreateUser": "admin",
  "CreateDate": "$dt",
  "CancelledDate": "1899-01-01T00:00:00",
  "CancelledUser": null,
  "GUTranID": "15010615234271604",
  "TenentID": 39,
  "CompanyID": 42,
  "ViewObjectID": 0,
  "ObjectID": null,
  "Status": 2,
  "OrderDetails": [

      "ChangeID": 0,
      "GUPackageID": "14100112243589402",
      "startdate": "2015-01-06T00:00:00"
    }
  ]
}
EOF
