Question

我正在尝试使用XMLHttpRequest将XML数据提交到外部API，该API将响应作为XML返回。

我编写了以下代码，但没有得到任何回复。虽然我得到200 http响应。在Firebug中，我将响应选项卡显示为空，而XML选项卡显示此错误“XML解析错误：找不到元素位置：moz-nullprincipal”

任何人都可以指出问题，我在我的本地机器上运行它。以下是我的完整代码。

Answer 1

data='<?xml version="1.0" encoding="utf-8" ?>';
data=data+'<LeadImportDatagram>';
    data=data+'<CompanyKey>302455</CompanyKey>';
    data=data+'<LeadInfo>;'

第13行必须是

data=data+'<LeadInfo>';

而不是

data=data+'<LeadInfo>;'

这会导致您获得XML错误。

XMLHttpRequest没有返回任何响应＆amp; XML错误
