我正在尝试使用oauth2 身份验证在beast boost C++ 中实现一个可以访问谷歌驱动器的应用程序。
https://developers.google.com/identity/protocols/OAuth2ForDevices
我尝试使用以下 POST 请求在 Postman 中获取用户代码:
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
它工作得很好,返回:
{
"verification_url": "https://www.google.com/device",
"expires_in": 1800,
"interval": 5,
"device_code": "AH-1Ng0IgBnIXIUeltwDoL7AwNExNTT0rozdxD5FMnP8dip4DaDi8_XtzK2aVT92YKYmYa7KWqHRVqw5AmJCDtalzK3k6pvbFw",
"user_code": "LWZY-BDXD"
}
现在我想在 C++ 中使用 boost 执行相同的请求,请求的代码片段如下:
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();
这个返回:

有什么想法可以像使用 Postman 一样返回 JSON 吗?
谢谢你!
