我在Python中相当新,所以这可能是一些问题。我DEVing在Python 3.0用VirusTotal API扫描文件
我不断遇到错误:
File "scan.py", line 7, in module
json = postfile.post_multipart(host,selector,fields,files)
File "C:\Python32\lib\postfile.py", line 10, in post_multipart
content_type, body = encode_multipart_formdata(fields,files)
File "C:\Python32\lib\postfile.py", line 42, encode_multipart_fordata
body = CRLF.join(L)
TypeError: sequence item 8: expected str instance, bytes found
当我尝试运行此代码连接和扫描与VirusTotal API的文件。此代码与网站中的示例类似。
import postfile
host = "www.virustotal.com"
selector = "https://www.virustotal.com/vtapi/v2/file/scan"
fields = [("apikey", "123123123123123123123123123")]
file_to_send = open("android-icq.apk", "rb").read()
files = [("file", "android-icq.apk", file_to_send)]
json = postfile.post_multipart(host, selector, fields, files)
print (json)
的postfile.py内容如下:这里的问题
import http.client, mimetypes
def post_multipart(host, selector, fields, files):
"""
Post fields and files to an http host as multipart/form-data.
fields is a sequence of (name, value) elements for regular form fields.
files is a sequence of (name, filename, value) elements for data to be uploaded as files

"""
content_type, body = encode_multipart_formdata(fields, files)
h = http.client.HTTP(host)
h.putrequest('POST', selector)
h.putheader('content-type', content_type)
h.putheader('content-length', str(len(body)))
h.endheaders()
h.send(body)
errcode, errmsg, headers = h.getreply()
return h.file.read()
def encode_multipart_formdata(fields, files):
"""

"""
BOUNDARY = '----------ThIs_Is_tHe_bouNdaRY_$'
CRLF = '\r\n'
L = []
for (key, value) in fields:
L.append('--' + BOUNDARY)
L.append('Content-Disposition: form-data; name="%s"' % key)
L.append('')
L.append(value)
for (key, filename, value) in files:
L.append('--' + BOUNDARY)
L.append('Content-Disposition: form-data; name="%s"; filename="%s"' % (key, filename))
L.append('Content-Type: %s' % get_content_type(filename))
L.append('')
L.append(value)
L.append('--' + BOUNDARY + '--')
L.append('')
body = CRLF.join(L)
content_type = 'multipart/form-data; boundary=%s' % BOUNDARY
return content_type, body
def get_content_type(filename):
return mimetypes.guess_type(filename)[0] or 'application/octet-stream'
任何想法?
感谢你为这个。但是,我能够使他们的其他样品工作。只是这个具体的例子,我无法运行。 我用2to3工具将2.x代码转换为3. 如果我仍然不会得到这个工作,那么我会考虑去2.x python。 非常感谢! – gwafito 2012-08-09 11:18:40
我切换到2.7 python和代码工作正常。这不是一个解决方案,但至少它工作! :) 谢谢! – gwafito 2012-08-09 12:11:58
