http库中nest_api的https问题求解

问答对人有帮助，内容完整，我也想知道答案 0 大家好，我正在尝试连接 Nest_api ( ) 除了我遇到的棘手的安全问题外，我什至无法从我尝试过的 API 中获取数据有几件事，我总是会收到“重定向”错误。这意味着我没有访问权限。我开始相信我在 HTTPS 请求方面遇到了一些问题。有人遇到过类似的问题吗？你可以在这里查看我的代码：我尝试访问服务器的部分是最后一段代码。代码：全选Basic Infos The goal is to let a switch respond on the data received from my nest Thermostad. I'm using the Nest_API to get the result Hardware Hardware: ESP8266 Description I'm trying to access the Nest API without any success. I always get some kind of redirection error. Or I get the 307 error code (redirection) or an 400. With the first one, there's no redirection location. What do i do wrong? Is it possible that the library doesn't support HTPPS? Is there a solution for it?
