urlgrabber發生錯誤

以下代碼用於從url中取回圖像失敗。由於某種原因，它會拋出一個KeyboardInterrupt（???），它會拋出我的腳本，即使我用try-catch將其包圍。urlgrabber發生錯誤

>>> import urlgrabber 
>>> urlgrabber.urlgrab('http://upload.wikimedia.org/wikipedia/en/thumb/e/e0/Passion_Flower.JPG/220px-Passion_Flower.JPG', filename='/home/eran/a.tmp', timeout = 2, retry = 2, reget = 'simple')

這將創建以下跟蹤：

的評論如果您只是想下載一個jpg'urllib.urlretrieve（'http://upload.wikimedia.org/wikipedia/en/thumb/e/e0/Passion_Flower.JPG/220px-Passion_Flower.JPG'， filename ='/ home/my.jpg'）'會爲你做 –

你爲什麼不使用要求？我認爲這很簡單，並達到你想要的。

pip install requests

和代碼是：你可以將它安裝使用

>>> import requests 
>>> r = requests.get('http://upload.wikimedia.org/wikipedia/en/thumb/e/e0/Passion_Flower.JPG/220px-Passion_Flower.JPG') 
>>> if r.status_code == 200: 
>>>  open('/tmp/flower.jpg', 'w').write(r.content)

問題是「*爲什麼失敗*？」如果問題是「*我該如何修復它*？」，您的答案將是關鍵點。或者「*我該怎麼試試*」？就目前而言，你的文章會做出非常好的評論而不是答案。 –

謝謝，羅布。得到它了。我剛來這地方。真的很感謝你的評論。 – Jorge
