【问题描述】:
所以我尝试通过 XML SOAP POST 进行 API 调用,我得到的错误是:“对象引用未设置为对象的实例”
site = 'https://webservices.autotask.net/atservices/1.5/atws.asmx'
data = """<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<queryxml>
<entity>contact</entity>
<query>
<field>firstname<expression op="equals">George</expression>
</field>
</query>
</queryxml>
</soap:Body>
</soap:Envelope>"""
headers = {
'Content-Type': 'application/soap+xml; charset=utf-8',
'Host': 'webservices.autotask.net',
'Content-Type': 'text/xml; charset=utf-8',
'Content-Length': len(data),
'SOAPAction': "http://autotask.net/ATWS/v1_5/query"
}
site = 'https://webservices.autotask.net/atservices/1.5/atws.asmx'
auth_handler = urllib2.HTTPBasicAuthHandler()
auth_handler.add_password(realm='webservices.autotask.net',
uri=site,
user='user,
passwd='pw')
opener = urllib2.build_opener(auth_handler)
urllib2.install_opener(opener)
page = urllib2.urlopen(site)
print(data)
req = urllib2.Request(site, data, headers)
response = urllib2.urlopen(req)
the_page = response.read()
print(the_page)
身份验证有效,我已使用此代码成功调用,现在唯一不同的是数据 XML SOAP POST。我会试试泡沫。
No Traceback only web 服务器错误:
打印出我发送的 XML SOAP POST:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<queryxml>
<entity>contact</entity>
<query>
<field>firstname<expression op="equals">George</expression>
</field>
</query>
</queryxml>
</soap:Body>
</soap:Envelope>
回复:

有什么想法吗?

【问题讨论】:
-
不,完全没有想法。不过,如果您发布了您正在使用的代码以及您获得的回溯,我可能会有一些。
-
您确定您使用的是 python 而不是 .NET?
-
您是否手动构建 SOAP POST 主体?使用python-suds 可以更轻松地调用您的SOAP 服务。
-
@Brian 是 python,但是服务器需要 SOAP 1.1 和 1.2

@Daniel No Traceback only web server error.
