HTTPException：對於url無效和/或缺少SSL證書：https://accounts.google.com/o/oauth2/token

Question

當我通過Google AppEngine調用Google Earth Engine（GEE）Python API時，它會拋出一個HTTPException，其中顯示「HTTPException：無效和/或缺少url證書的SSL證書：https://accounts.google.com/o/oauth2/token」。該項目在新年假期前運行良好，但當我在昨天進行測試時，它突然爆發，沒有對自己的代碼進行任何更改。

The detailed error information

Answer 1

我也經歷着我與App Engine python腳本同樣的問題。 這是前幾天罰款運行和accounts.google.com證書有效期至三月，9日2017年

編輯：它看起來像這個問題已經在幾個小時前這裏報道：https://code.google.com/p/googleappengine/issues/detail?id=13477

Answer 2

在the tracker for this GAE issue，維護者給出一個解決方法：

作爲臨時解決辦法，你可以用https://curl.haxx.se/ca/cacert.pem

更換過期urlfetch_cacerts.txt 0

在Linux上，你可以使用下面的命令： wget的https://curl.haxx.se/ca/cacert.pem -O {的Python SDK的根} /lib/cacerts/urlfetch_cacerts.txt

Answer 3

對於Windows，因爲SDK存儲在管理員讀 - 只有區域，我使用Windows文件資源管理器分兩步而不是腳本。

首先下載https://curl.haxx.se/ca/cacert.pem到文件夾，例如，下載。

curl https://curl.haxx.se/ca/cacert.pem > urlfetch_cacerts.txt 

您還可以使用瀏覽器下載文件並重命名它。

檢查您的cacerts存儲在哪裏。我發現他們在

C:\Program Files (x86)\Google\google_appengine\lib\cacerts 

其他report它：

C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\platform\google_appengine\lib\cacerts\urlfetch_cacerts.txt 

使用管理員憑據，重命名文件urlfetch_cacerts.txt別的東西。

然後將下載的文件cacerts.pem複製到

C:\Program Files (x86)\Google\google_appengine\lib\cacerts 

，並改名爲urlfetch_cacerts.txt

瞧！
