Question

我们正在关注“https://developer.nest.com/documentation/cloud/how-to-auth”链接，以访问Google嵌套中的恒温器详细信息。

我们能够执行第2步以获取授权凭据（PIN），并执行步骤3交换访问令牌的授权码。下面给出了步骤3的日志，我们从谷歌服务器获取访问令牌

    ====================Requesting Nest server for Access Token==============
    root@buildsys:~# curl --data    'client_id=46694fbc-a66c-4e30-91bd-ce8f4a58258d&code=JKL2369W&client_secret=ULVfZ3xYZvxOWHgtLLe5gUqAe&grant_type=authorization_code'  https://api.home.nest.com/oauth2/access_token
 /*Curl output for access token*/   

    {"access_token":"c.G8YcMzNFKk3STuQSx8qVSk9etBmUD5T6S2Wbq9eiDdxtyiMH34Ci6QBR8l3s1Xx1bC8u8B0lrsz55zvuYzR2vBEIdfRZCCPMc9qOAK6RDuo2EZ9uFsY9EVCVd5K24MMrFkkjyCV71SZiVuNv","expires_in":315360000}

    ===========================================================================

我们使用curl版本7.40，如下所示

 ====================Curl Version ======================================
    root@buildsys:~# curl --version
    curl 7.40.0 (i686-pc-linux-gnu) libcurl/7.36.0 OpenSSL/1.0.1f zlib/1.2.8 libidn/1.28
    Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smtp smtps telnet tftp
    Features: AsynchDNS IDN IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP
    ======================================================================

此外，我们正在使用REST服务，我们正在使用其余示例来调用Nest API，但是在证书验证之后我们没有成功，当重定向到firebase URL时它会给出 “在DNS缓存中找不到主机名”。下面给出了相同的日志。

但我们可以更改恒温器的温度值并设置为离开模式，所有操作都可以在Web浏览器中执行，但在其余服务中则无法正常工作。

请帮助我解决问题。

此致沙市。
