检索用户的公开Goog​​le/gmail图片 [英] Retrieving a user's public google/gmail picture

问题描述

我正在使用gmail-api编写基于电子邮件的应用程序，并且我需要检索用户公共图片以获取源自Google的电子邮件地址. 我见过其他应用程序可以做到这一点，但是我似乎无法可靠地获取此数据.

更多信息:

• 我正在使用oauth2登录用户-我在那里请求任何类型的权限都没有问题.
• 我尝试使用google + api检索图像-但它需要一个userID-而且我不知道如何获取电子邮件地址的userId(gmail-api不会提供它，afaik)
• 我尝试使用通讯录API-但它仅提供用户通讯录的图像，而电子邮件客户端也可以显示其他用户的图像.

谢谢！

如果我拥有其他用户的用户名，我知道我可以从google plus接收所需的图像.但是，我找不到基于电子邮件地址获取用户ID的方法.

解决方案

非常简单

有一个小问题.

您只能直接从gmail获取Google+个人资料的图片.

更新:

该API已被弃用，并将于2019年1月被关闭.请尽快迁移到Google Photos Library API，以避免对您的应用程序造成干扰.

I'm writing an email-based application using the gmail-api, and i need to retrieve user public images for email address originating from google. I've seen other applications do that, but i can't seem a way to reliably get this data.

some more information:

• i'm using oauth2 to sign the user in - and i have no problem requesting any type of permissions there.
• i've tried retrieving the image using the google+ api - but it requires a userID for that - and i don't know how to get the userId for the email address (gmail-api doesn't give it, afaik).
• i've tried using the contacts API - but it only gives images for the user's contacts, while the email clients can display images from other users as well.

Thanks!

Edit:

I know i can receive the required images from google plus, if i have the other user's userid. however, i can't find a way to get the userid based on an email address.

解决方案

Is very easy

http://picasaweb.google.com/data/entry/api/user/<hereYourUserIdOrYourEmail>?alt=json

just has a little problem.

You only can get the picture of your Google+ profile, not directly from your gmail.

UPDATE:

This API is being deprecated and will be turned down in January 2019. Migrate to Google Photos Library API as soon as possible to avoid disruptions to your application.
