当在url和参数中传入逗号(，)时，Twitter流api返回未经授权

Question

我使用c#代码来使用api，当我不添加逗号(，)但使用逗号返回未经授权时，它可以正常工作，逗号编码是否有任何问题?

url

https://stream.twitter.com/1.1/statuses/filter.json?track=twitter&位置= -122.75,36.8,-121.75,37.8

头参数

basestringParameters。添加("跟踪"、"推特");basestringParameters。Add("位置",-122.75,36.8,-121.75,37.8);

my base String
