        },
        "runAfter": {

        },
        "type": "Http"
      }
    }

It reads "temp" as "test" : @json(body('http'))['candidates'][0]['location']['x']"

If I change this line to 

    "temp": "@json(body('http'))['candidates'][0]['location']['x']"

It read the correct value from json. Not sure if its a bug, or I am missing some syntax.

您可以尝试 Steven 回答的内容（https://stackoverflow.com/a/44062649/7997843）或者这对我来说更明确：

"temp": "@concat('\"test\":', json(body('http'))['candidates'][0]['location']['x'])"

我建议您在此处阅读有关工作流定义语言中的字符串插值：https ://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-workflow-definition-language#Expressions

你的情况似乎是一个极限情况。要么你用@ou开始你的表达式，@{然后你的函数的名字，或者你可以从一个字符串开始，但是你别无选择，只能使用 @{

您可以尝试使用以下语法：

"temp": "\"test\": @{json(body('http'))['candidates'][0]['location']['x']}"
