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

我有一个REST端点是/ geo / search，并且需要一些长/纬度坐标作为请求的一部分发送（GEO多边形）。

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

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

• 我将如何访问路线中的这些参数？

使用JQuery.param：

客户：

 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 

回答＃2 – 感谢@Brad：

服务器 – 快车路线：

 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"]] 

我的问题是试图通过这些作为path的一部分，而不是他们应该的参数。
