Question

我从json对象读取了jq的属性，并将其存储到变量中。

我现在想阅读这些变量，并从根本上在字符串中找到一个单词并将其替换为全局shell变量。

我已经从JSON文件中设置了JSON ID

# Set Json ID's
TARGET_ID=$(jq '.DefaultCacheBehavior.TargetOriginId' distconfig.json)
DOMAIN_NAME=$(jq '.Origins.Items[0].DomainName' distconfig.json)
ORIGIN_ID=$(jq '.Origins.Items[0].Id' distconfig.json)

echo "$TARGET_ID"
echo "$DOMAIN_NAME"
echo "$ORIGIN_ID"

这将返回

"S3-Website-stag4.example.io.s3-website.us-east-2.amazonaws.com"
"stag4.example.io.s3-website.us-east-2.amazonaws.com"
"S3-Website-stag4.example.io.s3-website.us-east-2.amazonaws.com"

我有我的位置ID变量，并希望将其写入以查找和替换这3个ID中的所有stag4引用。

然后，我想将这3个ID写入初始json对象，或为其创建一个临时版本。

例如，如果： $DOMAIN_NAME是"stag4.example.io.s3-website.us-east-2.amazonaws.com"

我基本上希望将其设置为：

$LOCATION_NAME="stag6"
DOMAIN_LOCATION="example.io"

"$DOMAIN_NAME=S3-Website-\$LOCATION_NAME\.example.io.s3-website.us-east-2.amazonaws.com"
"$TARGET_ID=\$LOCATION_NAME\.example.io.s3-website.us-east-2.amazonaws.com"
"$ORIGIN_ID=S3-Website-\$LOCATION_NAME\.example.io.s3-website.us-east-2.amazonaws.com"

然后将这3个文件写入临时文件或新的json文件中，这样我就可以运行cloudformation命令了：

aws cloudfront create-distribution --distribution-config file://disttemp.json

我现在已经从初始json文件中构建了适当的变量，如下所示：

$LOCATION_NAME="stag6"
DOMAIN_LOCATION="example.io"

echo "Build New IDs"
TARGET_ID_BUILT="S3-Website-$LOCATION_NAME.$DOMAIN_LOCATION.s3-website.us-east-2.amazonaws.com"
DOMAIN_NAME_BUILT="$LOCATION_NAME.$DOMAIN_LOCATION.s3-website.us-east-2.amazonaws.com"
ORIGIN_ID_BUILT="S3-Website-$LOCATION_NAME.$DOMAIN_LOCATION.s3-website.us-east-2.amazonaws.com"

echo "$TARGET_ID_BUILT"
echo "$DOMAIN_NAME_BUILT"
echo "$ORIGIN_ID_BUILT"

如何使用jq将这些变量写入json文件？

Answer 1

您应该使用> (defparameter *small* 1) *SMALL* > (defparameter *big* 100) *BIG* > (defun guess-my-number () (ash (+ *small* *big*) -1)) GUESS-MY-NUMBER > (guess-my-number) 50进行替换，然后将值重新注入JSON。

sed

输出 echo $TARGET_ID | sed 's/stag4/stag5/g'

接下来，我们将值放回原始JSON，从技术上讲，这将输出新的JSON并且不会编辑文件，但是，您可以通过临时保存到tmp文件来轻松解决此问题。 / p>

我们将使用--arg标志引用我们的bash变量并为我们的字段设置新值

S3-Website-stag5.example.io.s3-website.us-east-2.amazonaws.com
