Node.js Express REST API - 使用GET请求访问JSON url params

Question

我有一个REST端点，它是/ geo / search，需要一些长/纬坐标作为请求（GEO多边形）的一部分发送。

• 我有什么办法可以在GET请求中使用JSON吗？我在想这个URL编码可能是一个解决方案：

  var data = encodeURIComponent({"coordinates":[[-122.610168,37.598167],[-122.288818,37.598167],[-122.288818,37.845833],[-122.610168,37.845833],[-122.610168,37.598167]]});
  

• 我如何在路线中访问这些参数？

使用JQuery.param：

客户端：

var test = {"coordinates":[[-122.610168,37.598167],[-122.288818,37.598167],[-122.288818,37.845833],[-122.610168,37.845833],[-122.610168,37.598167]]};

    console.log($.param( test ));

输出：

coordinates%5B0%5D%5B%5D=-122.610168&coordinates%5B0%5D%5B%5D=37.598167&coordinates%5B1%5D%5B%5D=-122.288818&coordinates%5B1%5D%5B%5D=37.598167&coordinates%5B2%5D%5B%5D=-122.288818&coordinates%5B2%5D%5B%5D=37.845833&coordinates%5B3%5D%5B%5D=-122.610168&coordinates%5B3%5D%5B%5D=37.845833&coordinates%5B4%5D%5B%5D=-122.610168&coordinates%5B4%5D%5B%5D=37.598167

服务器 - 快速路线：

router.get('/search_polygon', function(req, res) {
    console.log('Server received: ' + JSON.stringify(req.query.coordinates));
...

输出：

Server received: [["-122.610168","37.598167"],["-122.288818","37.598167"],["-122.288818","37.845833"],["-122.610168","37.845833"],["-122.610168","37.598167"]]

我的问题是尝试将这些作为路径的一部分传递，而不是作为参数传递。
