将帐户与Google Home设备关联时，授权授权流程失败

Question

我能够将授权代码重定向回重定向网址，这可以在oauth2.0 playground工具中看到。但是当从授权服务器访问令牌时，我在诸如client_id，client_secret，grant_type和代码之类的参数中获取空值。这里是重定向网址发送授权码

  

https://oauth-redirect.googleusercontent.com/r/skillid?state=xyz&code=aW1vbml

     

Http / 1.1 400错误请求   内容类型：application / json;字符集= UTF-8   {     “error_description”：“错误请求”，     “错误”：“invalid_grant”}

OAuthASResponse.OAuthAuthorizationResponseBuilder builder = OAuthASResponse .authorizationResponse(request,HttpServletResponse.SC_FOUND);' builder.setParam("code", token); builder.setParam("state", state); final OAuthResponse response = builder.location(redirectURI).buildQueryMessage(); URI url = new URI(response.getLocationUri()); return Response.status(response.getResponseStatus()).location(url).build();
