JMETER - Formatting JSON with JsonBuilder

问题

抱歉，我无法访问外部链接或执行代码，但我可以为您提供如何在现有的Groovy代码中将所需的对象添加到最终JSON中的指导：

要将额外的对象添加到最终JSON中，您可以在生成books数组后，创建一个包含您所需对象的Map，并将其添加到最终的JSON结构中。以下是一种修改代码的方法：

  1. def arraySize = vars.entrySet().findAll { entry -> entry.getKey().startsWith('isbn_') }.size()
  3. def books = []
  5. 1.upto(arraySize, {index ->
  6.     books.add([publisher: vars.get('publisherName'),
  7.                ISBN: vars.get('isbn_' + index),
  8.                Price: vars.get('price_' + index),
  9.                Publisher: vars.get('publisher_' + index),
  10.                "Static Value that doesn't change": 100
  11.     ])
  12. })
  14. // 创建您要添加的额外对象
  15. def extraObject = [
  16.     publisher: vars.get('publisherName'), // 这里使用与数组中相同的值
  17.     ISBN: vars.get('your_extra_isbn'), // 替换为您的额外ISBN变量
  18.     Price: vars.get('your_extra_price'), // 替换为您的额外价格变量
  19.     Publisher: vars.get('your_extra_publisher'), // 替换为您的额外出版商变量
  20.     "Static Value that will be the same for all items": 100
  21. ]
  23. // 创建最终的JSON结构，将额外对象添加到books数组后面
  24. def finalJson = new groovy.json.JsonBuilder([
  25.     books: books + [extraObject], // 将额外对象添加到数组末尾
  26.     meta: [
  27.         tag: [
  28.             searchNumber: vars.get('searchNo')
  29.         ]
  30.     ]
  31. ]).toPrettyString()
  33. log.info(finalJson)

请注意，上述代码中的your_extra_isbn、your_extra_price 和 your_extra_publisher 应替换为您要添加的额外对象的变量名称。这将创建一个包含额外对象的最终JSON，并在books数组的末尾添加它。

Hello I previously asked how to dynamically generate a json array using Groovy here:

https://stackoverflow.com/questions/76569179/jmeter-populate-a-json-request-for-all-items-in-an-array

The provided solution worked great, however I need to add an additional object after the final item in the array. Because the toprettystring formats the array I am unsure how to insert the object into the final result.

Here is an example of the final JSON:

  1. {
  2.  "books": [
  3.         {
  4.             "publisher": ${publisherName}, //variable but it's the same for all items in this request
  5.             "ISBN": ${isbn_1},  //the next three are from from 3 different arrays 
  6.             "Price": ${price_1},
  7.             "Publisher": ${publisher_1},
  8.             "Static Value that doesn't change": 100
  9.        
  10.         },
  12.         {
  13.             "publisher": ${publisherName}, //variable but it's the same for all items in this request
  14.             "ISBN": ${isbn_2},  //the next three are from from 3 different arrays 
  15.             "Price": ${price_2},
  16.             "Publisher": ${publisher_2},
  17.             "Static Value that will be the same for all items": 100
  18.        
  19.         },
  20.         
  21.     ],
  22.     "meta": {
  23.         "tag": {
  24.             "searchNumber": ${searchNo}
  25.         }
  26.     }
  27. }

The solution for the previous question was to use a JSR223 Preprocessor and generate it as follows:

  1. def arraySize = vars.entrySet().findAll { entry -> entry.getKey().startsWith('isbn_') }.size()
  3. def books = []
  5. 1.upto(arraySize, {index ->
  6.     books.add([publisher:vars.get('publisherName'),
  7.                ISBN: vars.get('isbn_' + index),
  8.                Price: vars.get('price_' + index),
  9.                Publisher:vars.get('publisher_' + index),
  10.                "Static Value that doesn't change": 100
  11.     ])
  12. })
  14. log.info(new groovy.json.JsonBuilder([books:books]).toPrettyString())

How could I modify this to enter the above object into the final JSON?

你的最终结果在这里形成：

  1. log.info(new groovy.json.JsonBuilder([books: books]).toPrettyString())

只需将所需字段添加到此映射中：[books: books]

例如，替换最后一行：

  1. def searchNo = ...
  2. def result = [
  3.     books: books,
  4.     meta: [
  5.         tag: [searchNumber: searchNo]
  6.     ]
  7. ]
  8. log.info(new groovy.json.JsonBuilder(result).toPrettyString())
英文:

your final result formed here:

  1. log.info(new groovy.json.JsonBuilder([books:books]).toPrettyString())

just add required fields into this map: [books:books]

for example instead of last line:

  1. def searchNo = ...
  2. def result=[
  3.     books: books,
  4.     meta: [
  5.         tag: [searchNumber: searchNo]
  6.     ]
  7. ]
  8. log.info(new groovy.json.JsonBuilder(result).toPrettyString())

请按以下方式修改您的代码：

  1. def arraySize = vars.entrySet().findAll { entry -> entry.getKey().startsWith('isbn_') }.size()
  3. def request = [:]
  5. def books = []
  7. 1.upto(arraySize, { index ->
  8.     books.add([publisher                         : vars.get('publisherName'),
  9.                ISBN                              : vars.get('isbn_' + index),
  10.                Price                             : vars.get('price_' + index),
  11.                Publisher                         : vars.get('publisher_' + index),
  12.                "Static Value that doesn't change": 100
  13.     ])
  14. })
  16. def meta = [tag: [searchNumber: vars.getObject('searchNo')]]
  17. request.put('books', books)
  18. request.put('meta', meta)
  19. log.info((new groovy.json.JsonBuilder(request).toPrettyString()))
