XML格式问题

XML格式问题,xml,soap,lxml,Xml,Soap,Lxml,我是第一次使用Salesforce SOAP API,因此我不熟悉SOAP格式问题等。我使用lxml库生成XML,但似乎存在格式问题 我收到的错误是:“信封元素的子元素必须是Header或Body元素”,这很奇怪,因为当我查看SalesforceLeadConverter.build_XML()方法生成的XML时,它看起来是正确的。这是 <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv=

我是第一次使用Salesforce SOAP API,因此我不熟悉SOAP格式问题等。我使用
lxml
库生成XML,但似乎存在格式问题

我收到的错误是:“信封元素的子元素必须是Header或Body元素”,这很奇怪,因为当我查看SalesforceLeadConverter.build_XML()方法生成的XML时,它看起来是正确的。这是

<?xml version="1.0" encoding="UTF-8"?>

SOAP正文和标头需要一个命名空间。 此外,以ns0为前缀的元素,ns1也需要一个名称空间声明

因此,您的有效SOAP将是:

下面修改的SalesforceLeadConverter类解决了标题/正文名称空间问题(MGorgon为我指明了正确的方向,对此我表示感谢)。最终引导我找到正确的解决方案

请注意,虽然名称空间问题已得到解决,但下面的代码仍然不起作用……出现了另一个问题,我得到了以下错误:

“没有可用于请求{enterprise.soap.sforce.com}convertLead的操作”

总之,这是我的soap.py文件:
