如何使用shell脚本将当前日期传递给curl查询？

Question

我使用CURL将数据插入弹性搜索,当我插入固定数据时,它工作正常.我正在尝试获取当前DateTime并分配给变量并使用我想要插入的对象.

这是我的剧本,

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并分配给CreateDate.我怎样才能做到这一点？

Answer 1

在你的字符串里面,改变

"CreateDate": "2015-01-01T15:23:42",

至

"CreateDate": "'"$(date +%Y-%m-%dT%H:%M:%S)"'",

在那里,我终止了'字符串,并在其中启动了一个"字符串$(date).否则,它不会被执行,而只是curl作为字符串传递给它.

您也可以事先将其分配给变量,并在以后使用它:

now=$(date +%Y-%m-%dT%H:%M:%S)

...

"CreateDate": "'"$now"'",

其他问题

更改

curl -XPUT 'http://localhost:9200/nondomain_order/orders/'+$number+'' -d '{

成

curl -XPUT 'http://localhost:9200/nondomain_order/orders/'"$number" -d '{

Bash连接只是两个字符串,它们之间没有空格.否则,它将查询URL http://localhost:9200/nondomain_order/orders/+0123456789+而不是http://localhost:9200/nondomain_order/orders/0123456789

(在这里,我保护number变量不受扩展的双引号,如果它发生了变化)

Answer 2

你可以这样做：

DATE_ISO=$(date +"%Y-%m-%dT%H:%M:%S")
...
curl -XPUT 'http://localhost:9200/nondomain_order/orders/'+$number+'' -d '{
...
   "CreateDate": "'"$DATE_ISO"'",
...
}'

Answer 3

我建议使用here-doc来摆脱所有的魔术引用,而不是在引号内使用引号.用curl这样的:

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

curl -XPUT 'http://localhost:9200/nondomain_order/orders/'$number -d@- <<EOF

  "OrderDate": "2015-01-06T15:23:42.7198285+05:30",

    }
  ]
}
