                        {
                            key: "",
                            value: "{"device":"24: 6f: 28: 7a: 87: c2","date":{"$lt":"time(Sun Feb 21 2021 16: 59: 53 GMT + 0300(Arabian Standard Time))"}}",

                        }
                    ]
                },
                url: "http://185.247.117.33/DB/Find"
            },
            response: []
        }
    ]
}

我从 api 获取数据的代码

fetch('https://www.postman.com/collections/3175ec392efd66dc9a50')
.then(response => response.json())
.then(data => {
    
  console.log(data.item[0].request.body.urlencoded[1].value)
  console.log(data.item[0].request.body.urlencoded[2].value) // Prints result from `response.json()` in getRequest
})
.catch(error => console.error(error))

请任何人帮助我如何在数组时间和天气条件下获取数据。

Answer 1

您需要在使用前解析结果。

fetch('https://www.postman.com/collections/3175ec392efd66dc9a50')
.then(response => response.json())
.then(data => {
    
  let value1 = JSON.parse(data.item[0].request.body.urlencoded[1].value)
  let value2 = JSON.parse(data.item[0].request.body.urlencoded[2].value);
   console.log ( value1.date, value2.date);
})
.catch(error => console.error(error))

Answer 2

urlencoded里面的数据是JSON格式的，使用JSON.parse转换成object；

 fetch('https://www.postman.com/collections/3175ec392efd66dc9a50').then(response => response.json()).then(data => { const value = data.item[0].request.body.urlencoded[1].value; const json = JSON.parse(value); console.log(json.device); console.log(json.date['$gt']); }).catch(error => console.error(error)) // Output: // 24:6f:28:7a:87:c2 // time(2021-02-21T13:10:48.593Z)
