Jmespath mengatur expr jmespath secara dinamis

Question

Saya menggunakan jmespath sebagai berikut

data = {
    "value": [
        {
            "datasetId": "cfafbeb1-8037-4d0c-896e-a46fb27ff229",
            "id": "5b218778-e7a5-4d73-8187-f10824047715",
            "name": "SalesMarketing2",
            "webUrl": "https://app.powerbi.com/groups/f089354e-8366-4e18-aea3-4cb4a3a50b48/reports/5b218778-e7a5-4d73-8187-f10824047715",
            "embedUrl": "https://app.powerbi.com/reportEmbed?reportId=5b218778-e7a5-4d73-8187-f10824047715&groupId=f089354e-8366-4e18-aea3-4cb4a3a50b48",
        },
        {
            "datasetId": "cfafbeb1-8037-4d0c-896e-a46fb27ff229",
            "id": "5b218778-e7a5-4d73-8187-f10824047715",
            "name": "SalesMarketing3",
            "webUrl": "https://app.powerbi.com/groups/f089354e-8366-4e18-aea3-4cb4a3a50b48/reports/5b218778-e7a5-4d73-8187-f10824047715",
            "embedUrl": "https://app.powerbi.com/reportEmbed?reportId=5b218778-e7a5-4d73-8187-f10824047715&groupId=f089354e-8366-4e18-aea3-4cb4a3a50b48",
        },
    ]
}

Dan mengatur jmespath expr secara dinamis sebagai:

report= 'SalesMarketing3'

jmespath.search(f"'value[?name == {report}]'", data)

Alih-alih mendapatkan kamus yang sesuai dengan "SalesMarketing3", saya mendapatkan keluaran sebagai berikut, Apakah saya melewatkan sesuatu?

'nilai [? name == SalesMarketing3]'

Bantuan apa pun sangat dihargai.

Answer 1

Masalah Anda berasal dari fakta bahwa Anda harus mencari string atau string mentah literal SalesMarketing3 .
Di JMESPath:

• Sebuah string dibatasi oleh tanda kutip tunggal: 'SalesMarketing3'
• Literal string mentah dibatasi oleh backticks: `SalesMarketing3`

Diberikan example.py :

import jmespath

data = {
    "value": [
        {
            "datasetId": "cfafbeb1-8037-4d0c-896e-a46fb27ff229",
            "id": "5b218778-e7a5-4d73-8187-f10824047715",
            "name": "SalesMarketing2",
            "webUrl": "https://app.powerbi.com/groups/f089354e-8366-4e18-aea3-4cb4a3a50b48/reports/5b218778-e7a5-4d73-8187-f10824047715",
            "embedUrl": "https://app.powerbi.com/reportEmbed?reportId=5b218778-e7a5-4d73-8187-f10824047715&groupId=f089354e-8366-4e18-aea3-4cb4a3a50b48",
        },
        {
            "datasetId": "cfafbeb1-8037-4d0c-896e-a46fb27ff229",
            "id": "5b218778-e7a5-4d73-8187-f10824047715",
            "name": "SalesMarketing3",
            "webUrl": "https://app.powerbi.com/groups/f089354e-8366-4e18-aea3-4cb4a3a50b48/reports/5b218778-e7a5-4d73-8187-f10824047715",
            "embedUrl": "https://app.powerbi.com/reportEmbed?reportId=5b218778-e7a5-4d73-8187-f10824047715&groupId=f089354e-8366-4e18-aea3-4cb4a3a50b48",
        },
    ]
}
report = 'SalesMarketing3'

print(jmespath.search(f"value[?name == `{report}`]", data))
## Another equivalent is:
# print(jmespath.search(f"value[?name == '{report}']", data))

Ini memberikan hasil yang diharapkan:

[
  {
    "datasetId": "cfafbeb1-8037-4d0c-896e-a46fb27ff229",
    "id": "5b218778-e7a5-4d73-8187-f10824047715",
    "name": "SalesMarketing3",
    "webUrl": "https://app.powerbi.com/groups/f089354e-8366-4e18-aea3-4cb4a3a50b48/reports/5b218778-e7a5-4d73-8187-f10824047715",
    "embedUrl": "https://app.powerbi.com/reportEmbed?reportId=5b218778-e7a5-4d73-8187-f10824047715&groupId=f089354e-8366-4e18-aea3-4cb4a3a50b48"
