一些小心得:
案例1
JSON:
{"hello":["a","b"]}
目標(biāo): 輸出一個json, 把數(shù)組 hello 中的值連接起來
jq-expression:
.hello | join(",") | {tmp:.} | .greeting="Welcome to Serverless Workflow, " + .tmp | {payload:{ greeting: .greeting}}
輸出:
{
"payload": {
"greeting": "Welcome to Serverless Workflow, a,b"
}
}
案例2
JSON:
{
"greeting": "John"
}
目標(biāo): 輸出一個json, 把 greeting 的值進(jìn)行修改
jq-expression:
.greeting="Welcome to Serverless Workflow, " + .greeting | {payload:{ greeting: .greeting}}
輸出:
{
"payload": {
"greeting": "Welcome to Serverless Workflow, John"
}
}
案例3
JSON:
John
目標(biāo): 輸出一個json, 把字符串包裝在其中
jq-expression:
.greeting="Welcome to Serverless Workflow, " + . | {payload:{ greeting: .greeting}}
輸出:
{
"payload": {
"greeting": "Welcome to Serverless Workflow, John"
}
}
