Question

我想从我的webServer调用/搜索Google云打印方法。

我正在使用OAuth Web服务器指南获取与范围一起使用的refresh_token / access_token：

https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile

然后我打电话给搜索Api，但我获得了403禁止。

    Request DefaultHttpRequest(chunked: false)
    POST /cloudprint/search HTTP/1.1
    Host: www.google.com
    Content-Type: text/plain; charset=utf-8
    Authorization: OAuth yb29.1.AADtN_U9PYyVhGpcS-8MpFhfGVbT4KsZKEoIX2HGePwoNXypjrSwVsS0pGzmaqhktfGBAQ
    Connection: keep-alive
    Accept: */*
    User-Agent: NING/1.0
    Content-Length: 0

    Response DefaultHttpResponse(chunked: true)
    HTTP/1.1 403 Forbidden

范围是否正确？我做错了什么？

Answer 1

你的范围错了。正确的范围是https://www.googleapis.com/auth/cloudprint

Answer 2

我认为这与您的HTTP标头'授权'有关。

在https://developers.google.com/oauthplayground/播放时，我看到生成的请求使用'授权：承载您的令牌'，而不是'授权：OAuth您的令牌'。
