如何将请求参数从URL传递到返回JavaScript中相同名称的对象的函数？

Question

我想将请求参数从快速路由器请求传递给函数，该函数将返回相同名称的对象，但是该函数返回参数名称。我看过函数参数的类型，它是'object'类型，但是req.params返回类型字符串。我该如何规避？router.get('/about/:place', (req, res) => {// the object  Mombasa = {    "Destination": "Mombasa",    "Price": 12000,    "Likes": 0,    "Gallery": [{        "image": "https://traveldiscoverkenya.com/wp-content/uploads/2016/05/Mombasa-2-768x499.jpg"    }, {        "image": "https://i2.wp.com/buildesign.co.ke/wp-content/uploads/2017/11/ez.jpg"    }]};// function that returns the object  getPlace = (placeName) => {    return placeName;}  // trying to send reaponse of whole object  res.json(getPlace(req.params.place));});预期结果：{“目的地”：“ Mombasa”，“价格”：12000，“喜欢”：0，“图库”：[{“图像”：“ https://traveldiscoverkenya.com/wp-content/uploads/2016/05/ Mombasa-2-768x499.jpg “}，{” image“：” https://i2.wp.com/buildesign.co.ke/wp-content/uploads/2017/11/ez.jpg “}]}实际结果：“蒙巴萨”
