错误：使用 Node.js 请求模块的 json 无效

Question

我正在尝试使用请求模块发布数据。这是代码，

var requestInfo = {
        tags: [
            {
                "name": 'UIW_IWIWU',
                "filters": {
                    "attributes": {
                        "VesselId": '2982'
                    }
                },
                "order": "asc"   
            }
        ],
        start: "15mi-ago",
        end: "30ms-ago"
    };


    request.post({
            uri:'http://localhost:3000/data-api',
            json: 'true',
            body: requestInfo
        },function (error, response, body) {
            res.send(response);         
        }
    );

以上代码在终端抛出JSON无效错误。

Error: Invalid json

这是堆栈跟踪：

Error: invalid json

Answer 1

请检查 JSON 结构

JSON 键必须是字符串

更新 JSON 结构

var requestInfo = {"tags": [{

        "name": "UIW_IWIWU",
        "filters": {
            "attributes": {
                "VesselId": 2982
            }
        },
        "order": "asc"
    }],
    "start": "15mi-ago",
    "end": "30ms-ago"
}
