我正在尝试通过zeep客户端将附件发送到soap webservice。
我尝试使用类似先前的问题中引用的包装器类TransportWithAttach：
class TransportWithAttach(Transport):
"""Transport with attachment"""
def __init__(self, cache=None, timeout=300, operation_timeout=None,
session=None):
self.attachments = {}
patch_things()
super(TransportWithAttach, self).__init__(
cache=cache, timeout=timeout, operation_timeout=operation_timeout,
session=session)
def post_xml(self, address, envelope, headers):
# Search for values that startswith FILETAG
filetags = envelope.xpath(
"//*[starts-with(text(), '{}')]".format(FILETAG))
# if there is some attached file we set the attachments
print('filetags -- ', filetags)
print('envelope -- ', envelope)
print('headers -- ', headers)
#if filetags:
# message = self.set_attachs(filetags, envelope, headers)
# else just the envelope
#else:
# message = etree_to_string(envelope)
message = self.set_attachs(envelope, headers)
print('message returned with attach --', message)
# post the data.
return self.post(address, message, headers)
def set_attachs(self, envelope, headers):
"""Set mtom attachs and return the right envelope"""
# let's get the mtom multi part.
mtom_part = get_multipart()
# let's set xop:Include for al the files.
# we need to do this before get the envelope part.
#files = [set_attachnode(f) for f in filetags]
# get the envelope part.
env_part = get_envelopepart(envelope)
# attach the env_part to the multipart.
mtom_part.attach(env_part)
# for each filename in files.
#for cid in files:
# attach the filepart to the multipart.
mtom_part.attach(self.get_attachpart())
# some other stuff.
bound = '--%s'.format(mtom_part.get_boundary())
marray = mtom_part.as_string().split(bound)
mtombody = bound
mtombody += bound.join(marray[1:])
mtom_part.add_header("Content-Length", str(len(mtombody)))
headers.update(dict(mtom_part.items()))
message = mtom_part.as_string().split('\n\n', 1)[1]
message = message.replace('\n', '\r\n', 5)
# return the messag for the post.
return message
def get_attachpart(self):
"""The file part"""
#attach = self.attachments[cid]
part = MIMEBase("text", "plain")
part.set_param('charset', 'us-ascii')
part.set_param('name', 'test.txt')
part['Content-Transfer-Encoding'] = "7bit"
part['Content-ID'] = "<test.txt>"
part['Content-Disposition'] = 'attachment; name="test.txt"; filename="test.txt"'
by = open("test.txt", "rb").read()
#by = f.read()
part.set_payload(by)
del part['mime-version']
return part
这应该在SOAP Web服务中发送文件，但我收到了错误content is not allowed in prolog。
python中是否有提供用于通过SOAP API发送文件的内置方法的软件包？
