Question

我尝试使用theoauth2身份验证来实现可以访问goast boost C ++的谷歌驱动器的应用。

https://developers.google.com/identity/protocols/OAuth2ForDevices

我尝试使用以下POST请求获取Postman中的用户代码：

POST /o/oauth2/device/code HTTP/1.1
Host: accounts.google.com
Content-Type: application/x-www-form-urlencoded
Cache-Control: no-cache


scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fdrive.file&client_id=610490019085-l1v2mv7lv95lu7cr111vbtqmp1bigv42.apps.googleusercontent.com

它完美无缺，回归：

{
"verification_url": "https://www.google.com/device",
"expires_in": 1800,
"interval": 5,
"device_code": "AH-1Ng0IgBnIXIUeltwDoL7AwNExNTT0rozdxD5FMnP8dip4DaDi8_XtzK2aVT92YKYmYa7KWqHRVqw5AmJCDtalzK3k6pvbFw",
"user_code": "LWZY-BDXD"

}

现在我想使用boost在C ++中执行相同的请求，并为请求提供以下代码段：

http::request<http::string_body> req{http::verb::post, "/o/oauth2/device/code", 11};

req.set(http::field::host, "accounts.google.com");
req.set("Cache-Control", "no-cache");
req.set(http::field::content_type, "application/x-www-form-urlencoded");
req.body() = "scope=https://www.googleapis.com/auth/drive.file&client_id=610490019085-l1v2mv7lv95lu7cr111vbtqmp1bigv42.apps.googleusercontent.com";

req.prepare_payload();

这个回归：

HTTP/1.0 307 Temporary Redirect
Content-Type: text/html; charset=UTF-8

我有什么想法可以像Postman一样返回JSON吗？

谢谢！

Beast是一个低级协议库，它对解析域名或连接套接字一无所知。它甚至不知道TCP / IP，只知道如何在符合Asio流概念要求的对象上序列化和反序列化HTTP / 1消息（例如：SyncReadStream或AsyncWriteStream）。你必须自己处理重定向。如果获得重定向响应，请提取Location字段值并解析URI，解析域，然后为指定资源发出另一个GET请求。

我希望其他人（也许是你？）将建立在野兽之上，并以开源库的形式提供更高级别的功能。
