如何使用 nodeJS 从 axios 库中获取有效的 JSON 响应

Question

我正在尝试使用 AXIOS 库访问 REST 端点，并且 response.data 在 console.log 中返回以下内容：

console.log(response.data) 的响应

{
  sqlQuery: "select type,subtype from wetrade_p2 where parent_id='69341269'",
  message: '1 rows selected',
  row: [ { column: [Array] } ]
}

但是当我在邮递员中点击相同的 REST 端点时，我可以得到整个响应 JSON，如下所示：

PostMan 输出（预期）：

{
    "sqlQuery": "select type,subtype from wetrade_p2 where parent_id='69341269'",
    "message": "2 rows selected",
    "row": [
        {
            "column": [
                {
                    "value": "W",
                    "name": "TYPE"
                },
                {
                    "value": "P",
                    "name": "STATUS"
                },
                {
                    "value": "0",
                    "name": "SUBTYPE"
                },
                {
                    "value": "USD",
                    "name": "CURRENCY"
                }
            ]
        },
        {
            "column": [
                {
                    "value": "W",
                    "name": "TYPE"
                },
                {
                    "value": "S",
                    "name": "STATUS"
                },
                {
                    "value": "0",
                    "name": "SUBTYPE"
                },
                {
                    "value": "USD",
                    "name": "CURRENCY"
                }
            ]
  
        }
    ]
}

我还尝试刺痛 response.data，它返回的响应低于无法解析（）

当我尝试使用 JSON.stringify(response.data) 时在 console.log 中得到以下响应：

sqlQuery: "select type,subtype from wetrade_p2 where parent_id=69341269"
message: "2 rows selected"
row: [
    {
        "column": [
            {
                "value": "W",
                "name": "TYPE"
            },
            {
                "value": "P",
                "name": "STATUS"
            },
            {
                "value": "0",
                "name": "SUBTYPE"
            },
            {
                "value": "USD",
                "name": "CURRENCY"
            }
        ]
    },
    {
        "column": [
            {
                "value": "W",
                "name": "TYPE"
            },
            {
                "value": "S",
                "name": "STATUS"
            },
            {
                "value": "0",
                "name": "SUBTYPE"
            },
            {
                "value": "USD",
                "name": "CURRENCY"
            }
        ]

    }
]

示例代码：

await axios[methodType](url, body, {
                httpsAgent:httpsAgent,
                headers: {
                    "Accept": "application/json",
                    "Content-Type": "application/json",
                    "Access-Control-Allow-Origin": true
                }
        
            }).then(response => {
                console.log("++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++")
                console.log(response.data);
                console.log(JSON.stringify(response.data))
                console.log("++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++")
                console.log(response);
                
            
           }).catch(error => {
                      
                        console.log(error);
           });

你确实得到了正确的数据，只是 node.js 没有在控制台/标准输出中显示它。您可以使用util.inspect() 获得更好的格式化输出。试试这个：

const util = require('util');
// ...
console.log(util.inspect(response.data, { showHidden: false, depth: null }));
