【问题描述】：

我现在通过 Get Json Value 键获取一个 arg 值

Create Session  Get_Inventory_Details   ${Base_URL}                 
${Headers}= Create Dictionary   Content-Type=application/json   Authorization=bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyTmFtZSI6InByaXRpc3dhaW4iLCJpYXQiOjE1Njc1MTQ2NDd9.o3qTPbj2KH6AgHpIf1BLV5nOlGL-fR83wSGAYyuWsBQ              
${Response}=    Get Request Get_Inventory_Details   inventorybyOutlet/7 headers=${Headers}          
Log To Console  ${Response.status_code}                     
Log Many    ${Response.content}                     
${actual_response}= Convert To String   ${Response.status_code}                 
Should Be Equal ${actual_response}  200 
${quantity}=    Get Json Value  ${Response.content} /0/currentInventory             
Run Keyword If  ${quantity}>10  Log Threshold Condition Pass    ELSE    Log Threshold Condition Fail

如果我想在 Get Json Value

中传递多个参数，可能的出路是什么

我试过了

${quantity}=    Get Json Value  ${Response.content} /0/currentInventory/0/itemid

Reference to Json Data


[ 
   { 
      "isInventoryOperationEnable":1,
      "itemId":1,
      "name":"Afghani Chicken Tikka Biryani (Heavy Eater)",
      "posName":"Afghani Chicken Tikka Biryani (Heavy Eater)",
      "image":"https://d30mle0t4iy75h.cloudfront.net/websiteV2/images/menuItems/AfghaniTikkaBiryani.jpg",
      "typeid":2,
      "isCombo":0,
      "currentInventory":100,
      "categoryId":1,
      "categoryname":"Biryani",
      "subCategoryId":1,
      "sequenceInCategory":1
   },
   { 
      "isInventoryOperationEnable":1,
      "itemId":3,
      "name":"Chicken Tikka Biryani (Heavy Eater)",
      "posName":"Chicken Tikka Biryani (Heavy Eater)",
      "image":"https://d30mle0t4iy75h.cloudfront.net/websiteV2/images/menuItems/ChickenTikkaBiryani.jpg",
      "typeid":2,
      "isCombo":0,
      "currentInventory":100,
      "categoryId":1,
      "categoryname":"Biryani",
      "subCategoryId":1,
      "sequenceInCategory":14
   }
      ]

但是 RobotFramework 会抛出错误：- JsonPointerException: Document '' 不支持索引，必须是映射/序列或支持 __getitem__

Error Message on RobotFramework

请任何人帮助找出在这种情况下如何传递多个 arg 的方法

谢谢

【问题讨论】：

如果有 JSON 数据以便可以复制粘贴（即不是图像格式）会很好。
请创建一个minimal reproducible example，其中包含一小块硬编码的 json 数据，模拟真实数据，但尽可能小以说明问题。
感谢您的建议，我已经添加了一小块Json数据供参考。

【解决方案1】：

Create Session  Get_Inventory_Details   ${Base_URL}                 
${Headers}= Create Dictionary   Content-Type=application/json   Authorization=bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyTmFtZSI6InByaXRpc3dhaW4iLCJpYXQiOjE1Njc1MTQ2NDd9.o3qTPbj2KH6AgHpIf1BLV5nOlGL-fR83wSGAYyuWsBQ              
${Response}=    Get Request Get_Inventory_Details   inventorybyOutlet/7 headers=${Headers}          
Log To Console  ${Response.status_code}                     
Log Many    ${Response.content}                     
${actual_response}= Convert To String   ${Response.status_code}                 
Should Be Equal ${actual_response}  200 
${response_content_json}=   To Json    ${Response.content}    #To Json is from RequestsLibrary
${quantity}=    Set Variable    ${response_content_json}[0][currentInventory]
Run Keyword If  ${quantity}>10  Log Threshold Condition Pass    ELSE    Log Threshold Condition Fail

在这种情况下，${quantity} 是 100。

注意两点：

转成JSON后，变量值可以像dictionary类型变量一样访问
To JSON 关键字来自RequestsLibrary
