C# 401 Twitter搜索位置筛选器中出现错误
我在Twitter API讨论上发布了一个类似的问题,但没有收到回复。我尝试了将近一周的时间从C#上的Twitter流媒体API公共流获取地理定位推文,但没有成功。下面是我正在使用的代码。当我用“轨迹”参数更改“位置”参数时,一切正常。但是位置过滤器总是返回401错误。有人能帮我写代码吗?C# 401 Twitter搜索位置筛选器中出现错误,c#,twitter,twitter-streaming-api,C#,Twitter,Twitter Streaming Api,我在Twitter API讨论上发布了一个类似的问题,但没有收到回复。我尝试了将近一周的时间从C#上的Twitter流媒体API公共流获取地理定位推文,但没有成功。下面是我正在使用的代码。当我用“轨迹”参数更改“位置”参数时,一切正常。但是位置过滤器总是返回401错误。有人能帮我写代码吗? 使用系统; 使用System.Collections.Generic; 使用System.IO; 使用System.Linq; Net系统; 使用System.Security.Cryptography;

提前感谢,,
Stefanos我可以看出您在位置筛选方面遇到了一些问题。 我面临着同样的问题,但我最终得到了一些答案
- 签名需要对逗号编码两次,将其转换为%252C。
- url只应将逗号编码一次,并将其转换为%2C。
我希望这将对您有所帮助:)我可以看出您在位置筛选方面遇到了一些问题。 我面临着同样的问题,但我最终得到了一些答案
