urllib

I wish to have my Python script download the Master data (Download, XLSX) Excel file from this Frankfurt stock exchange webpage . When to retrieve it with urrlib and wget , it turns out that the URL leads to a Blob and the file downloaded is only 289 bytes and unreadable. http://www.xetra.com/blob/1193366/b2f210876702b8e08e40b8ecb769a02e/data/All-tradable-ETFs-ETCs-and-ETNs.xlsx I'm entirely unfamiliar with Blobs and have these questions: Can the file "behind the Blob" be successfully retrieved using Python? If so, is it necessary to uncover the "true" URL behind the Blob – if there is such a

From reading various posts, it seems like JavaScript's unescape() is equivalent to Pythons urllib.unquote() , however when I test both I get different results: In browser console: unescape('%u003c%u0062%u0072%u003e'); output: <br> In Python interpreter: import urllib urllib.unquote('%u003c%u0062%u0072%u003e') output: %u003c%u0062%u0072%u003e I would expect Python to also return <br> . Any ideas as to what I'm missing here? Thanks! %uxxxx is a non standard URL encoding scheme that is not supported by urllib.parse.unquote() (Py 3) / urllib.unquote() (Py 2). It was only ever part of ECMAScript

I'm fairly new to python, so I apologize in advance if this is something simple I'm missing. I'm trying to post data to a multipart form in python. The script runs, but it won't post. I'm not sure what I'm doing wrong. import urllib, urllib2 from poster.encode import multipart_encode from poster.streaminghttp import register_openers def toqueXF(): register_openers() url = "http://localhost/trunk/admin/new.php" values = {'form':open('/test.pdf'), 'bandingxml':open('/banding.xml'), 'desc':'description'} data, headers = multipart_encode(values) request = urllib2.Request(url, data, headers)

I'm writing a web scraper than needs to scrape only the thumbnail of an image from the url. This is my function using, the urlib library. def create_thumb(self): if self.url and not self.thumbnail: image = urllib.request.urlretrieve(self.url) # Create the thumbnail of dimension size size = 350, 350 t_img = Imagelib.open(image[0]) t_img.thumbnail(size) # Get the directory name where the temp image was stored # by urlretrieve dir_name = os.path.dirname(image[0]) # Get the image name from the url img_name = os.path.basename(self.url) # Save the thumbnail in the same temp directory # where

I'm trying to make a program that will open a directory, then use regular expressions to get the names of powerpoints and then create files locally and copy their content. When I run this it appears to work, however when I actually try to open the files they keep saying the version is wrong. from urllib.request import urlopen import re urlpath = urlopen('http://www.divms.uiowa.edu/~jni/courses/ProgrammignInCobol/presentation/') string = urlpath.read().decode('utf-8') pattern = re.compile('ch[0-9]*.ppt') #the pattern actually creates duplicates in the list filelist = pattern.findall(string)

当url地址含有中文，或者参数有中文的时候，这个算是很正常了，但是把这样的url作为参数传递的时候（最常见的callback），需要把一些中文甚至'/'做一下编码转换。 所以对于一些中文或者字符，url不识别的，则需要进行转换，转换结果如下： 一、urlencode urllib库里面有个urlencode函数，可以把key-value这样的键值对转换成我们想要的格式，返回的是a=1&b=2这样的字符串，比如： import urllib.parse values={} values['username']='02蔡彩虹' values['password']='ddddd?' url="http://www.baidu.com" data=urllib.parse.urlencode(values) print(data) 结果如下： 如果只想对一个字符串进行urlencode转换，怎么办？urllib提供另外一个函数：quote() import urllib.parse s='长春' s=urllib.parse.quote(s) print(s) 输出结果为： 二、urldecode 当urlencode之后的字符串传递过来之后，接受完毕就要解码了——urldecode。urllib提供了unquote()这个函数，可没有urldecode()！ s='%E5%B9%BF
