我的应用程序中的Google云打印API集成 [英] Google cloud print API integration in my application
问题描述
我正在尝试将Google云打印集成到Android应用程序中.我不想通过Print框架进行操作，因为我的要求是直接从应用程序进行打印，而无需任何选择过程.
为此，我已经集成了Google身份验证并为此生成了访问令牌.我正在尝试使用access_token加载打印机列表，但始终出现错误.
以下是我的API调用详细信息:
URL: https://www.google.com/cloudprint/search
类型:POST
标题:
授权:OAuth ACCESS_TOKEN
Content-Type:应用程序/json
错误消息是:
<HTML>
<HEAD>
<TITLE>User credentials required</TITLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF" TEXT="#000000">
<H1>User credentials required</H1>
<H2>Error 403</H2>
</BODY>
</HTML>
任何帮助表示赞赏.
创建一个Google网上论坛.通过直接邀请添加成员:
- 您的gmail帐户(gmail电子邮件地址)
- 提供访问令牌的Google服务帐户(服务帐户电子邮件地址)
然后按照以下步骤操作:
- 转到google.com/cloudprint
- 选择打印机，然后单击共享"选项卡.在邀请人员下添加以下成员:
- google服务帐户的电子邮件地址
- google网上论坛的电子邮件地址(例如xyz@googlegroups.com)
然后尝试调用GCP API.它将完美运行.
I am trying to integrate Google cloud print in Android Application. I do not want to do it through Print framework as my requirement is to directly print from application without any selection process.

Content-Type : application/json
Error message is:
<HTML>
<HEAD>

<H1>User credentials required</H1>
<H2>Error 403</H2>
</BODY>
</HTML>
Any help appreciated.
Create a google group. Add members by direct invite:
- Your gmail account (gmail email address)
- Your google service account from which access token was furnished (service account email address)
Then follow the below steps:
- Go to google.com/cloudprint
- Select your printer and click Share tab. Add following members under invite people:
- google service account email address
- google group email address ( eg, xyz@googlegroups.com)
Then try calling GCP APIs. It will work perfectly.
