如何使用 Json Extractor 从 Jmeter 中嵌套的 Json 中提取数据

Question

{"data": {"callOrders": [{ "promotionId": null, "Promotion": null, "Lines": [ { "id": 5105808, "quantity": 10, "skuId": 769, "callId": 494285, "skuBatchId": 733, "amountDetails": { "rate": 197.53, "grossAmount": 2232.089, "netAmount": 2232.089, "taxAmount": 256.789, "taxableAmount": 1975.3, "subTotal": 1975.3, "billDiscount": 0, "tradeDiscount": 0, "discountAmount": 0, "promotionDiscount": 0, "topUpDiscount": 0, "__typename": "AmountDetail" }, "rateDetails": { "rlp": 197.53, "rlpWithVat": 223.2089, "netPrice": 197.53, "netPriceWithVat": 223.2089, "__typename": "RateDetail" }, "SKU": { "id": 769, "title": "H&S 2in1 Active Protect 180 ml x 24 [82302894]", "__typename": "SKU" }, "SKUBatch": { "priceDetails": { "rlp": 197.53, "dlp": 186.35, "vatPercentage": 0.13, "mrpSrp": 250, "mrpStatus": true, "__typename": "SKUPrice" }, "batchDetails": { "batchNumber": "DEFAULT_BATCH", "__typename": "SKUBatch" }, "usageDate": { "manufacture": "0000-00-00", "expiry": "0000-00-00", "__typename": "SKUUsag e" }, "updatedAt": "2019-11-05", "active": true, "__typename": "SKUBatchRate" }, "Promotion": { "id": null, "title": null, "type": null, "scope": null, "criteria": null, "__typename": "Promotion" }, "promotionId": null, "distributorId": 16, "__typename": "Line", "inStock": "INSTOCK", "freeSku": false, "focusedSku": false }, { "id": 5105809, "quantity": 50, "skuId": 95, "callId": 494285, "skuBatchId": 111, "amountDetails": { "rate": 56.89, "grossAmount": 3214.2852, "netAmount": 3214.285, "taxAmount": 369.785, "taxableAmount": 2844.5, "subTotal": 2844.5, "billDiscount": 0, "tradeDiscount": 0, "discountAmount": 0, "promotionDiscount": 0, "topUpDiscount": 0, "__typename": "AmountDetail" }, "rateDetails": { "rlp": 56.89, "rlpWithVat": 64.2857, "netPrice": 56.89, "netPriceWithVat": 64.2857, "__typename": "RateDetail" }, "SKU": { "id": 95, "title": "Whisper Choice 6s x 96 [82252488]", "__typename": "SKU" }, "SKUBatch": { "priceDetails": { "rlp": 56.89, "dlp": 53.67, "vatPercentage": 0.13, "mr pSrp": 72, "mrpStatus": true, "__typename": "SKUPrice" }, "batchDetails": { "batchNumber": "DEFAULT_BATCH", "__typename": "SKUBatch" }, "usageDate": { "manufacture": "0000-00-00", "expiry": "0000-00-00", "__typename": "SKUUsage" }, "updatedAt": "2016-08-15", "active": true, "__typename": "SKUBatchRate" }, "Promotion": { "id": null, "title": null, "type": null, "scope": null, "criteria": null, "__typename": "Promotion" }, "promotionId": null, "distributorId": 16, "__typename": "Line", "inStock": "INSTOCK", "freeSku": false, "focusedSku": false }, { "id": 5105810, "quantity": 10, "skuId": 82, "callId": 494285, "skuBatchId": 551, "amountDetails": { "rate": 281.88, "grossAmount": 3185.244, "netAmount": 3185.244, "taxAmount": 366.444, "taxableAmount": 2818.8, "subTotal": 2818.8, "billDiscount": 0, "tradeDiscount": 0, "discountAmount": 0, "promotionDiscount": 0, "topUpDiscount": 0, "__typename": "AmountDetail" }, "rateDetails": { "rlp": 281.88, "rlpWithVat": 318.5244, "netPrice": 281.88, "ne tPriceWithVat": 318.5244, "__typename": "RateDetail" }, "SKU": { "id": 82, "title": "Ariel Oxyblu 1 kg x 24 [82250306]", "__typename": "SKU" }, "SKUBatch": { "priceDetails": { "rlp": 281.88, "dlp": 268.45, "vatPercentage": 0.13, "mrpSrp": 344, "mrpStatus": true, "__typename": "SKUPrice" }, "batchDetails": { "batchNumber": "DEFAULT_BATCH", "__typename": "SKUBatch" }, "usageDate": { "manufacture": "0000-00-00", "expiry": "0000-00-00", "__typename": "SKUUsage" }, "updatedAt": "2018-01-31", "active": true, "__typename": "SKUBatchRate" }, "Promotion": { "id": null, "title": null, "type": null, "scope": null, "criteria": null, "__typename": "Promotion" }, "promotionId": null, "distributorId": 16, "__typename": "Line", "inStock": "INSTOCK", "freeSku": false, "focusedSku": false } ], "__typename": "PromotionOrder" }]}}

Using $..Lines..id I am getting this [ 5105808, 769, null, 5105809, 95, null, 5105810, 82, null ]

But I want to get value [ 5105808, 5105809, 5105810] only. What should be the way to achieve it?

Answer 1

This is a possible solution:

$..[?(@.skuId)].id

This gets elements that have the skuId attribute and extracts the id attribute.

Answer 2

You're using .. which is a deep scan operator which means that you're looking for all id attribute values no matter where they're located in the JSON.

If you want to get only id of the attributes which are direct children of the Lines object - you need to amend your query to look like: $..Lines[*].id
