问https://apis.map.qq.com/ws/place/v1/suggestion 查询 JSONP、sig校验，接口报错？

    import { jsonp } from 'vue-jsonp'
    import md5 from 'blueimp-md5'
    function searchLocation(params: any) {
            const key = 'xxxx'
            const SecretKey = 'xxxx'
            const url = `/ws/place/v1/suggestion?key=${key}&keyword=${params.keyword}&region=${params.region}${SecretKey}`
            let sig = md5(url) // 这个地方的md5没有问题 与这个工具返回一致 https://lbs.qq.com/service/webService/WebServiceAPITool/md5_tool

            jsonp(`https://apis.map.qq.com/ws/place/v1/suggestion`, {
                callbackQuery: 'callback', 
                callbackName: 'jsonpCallback',
                keyword: params.keyword,
                key,
                sig,
                output: 'jsonp',
            })
                .then((item: any) => {
                    console.log(item)
                })
                .catch((e) => {
                    console.log(e)
                })
        }

        searchLocation({
            keyword: '江苏',
            region: '',
        })
        
        
        通过jsonp请求，sig无法通过校验，报错
