从URL下载Python文件

Question

试图从该URL下载文件。这是一个excel文件，它只下载1 kb的文件。虽然文件大小实际上是7MB。我不明白这里必须

做，但如果复制并粘贴到IE的URL，整个文件下载

res = requests.get('http://fescodoc.***.com/fescodoc/component/getcontent?objectId=09016fe98f2b59bb&current=true') 
res.raise_for_status() 
playFile = open('DC_Estimation Form.xlsm', 'wb') 
for chunk in res.iter_content(1024): 
    playFile.write(chunk) 

Answer 1

它更容易使用的内置模块urllib对于这样的情况：https://docs.python.org/2/library/urllib.html#urllib.urlretrieve

urllib.urlretrieve('http://fescodoc/component/.', 'DC_Estimation_Form.xslm') 

Answer 2

您应该设置stream为true在get()，

res = requests.get('http://fescodoc.***.com/fescodoc/component/getcontent?objectId=09016fe98f2b59bb&current=true', stream=True) 
res.raise_for_status() 
with open('DC_Estimation Form.xlsm', 'wb') as playFile: 
    for chunk in res.iter_content(1024): 
     playFile.write(chunk)
