当 Perl 的 SOAP::Lite 模块查询时，Java JAX-WS 服务返回 SOAP 错误

Question

我有一个简单的 Java 服务来获取当前时间。

我写了一个 Perl 客户端来访问它。

#! /usr/bin/perl -w
use SOAP::Lite;
my $url = 'http://127.0.0.1:9876/ts?wsdl';
my $service = SOAP::Lite->service($url)->soapversion('1.1');

print "\nCurrent time is: ", $service->getTimeAsString();
print "\nElapsed milliseconds from the epoch: ", $service->getTimeAsElapsed();

一旦客户端发出调用(也在同一台机器上)，服务就会记录下面的异常，并向客户端返回 SOAP 错误而不是预期的响应。

知道为什么吗？

有点晚了，但对于其他遇到此问题的人来说，问题是 SOAP::Lite 盲目地从 WSDL 文件中导入 namespace 并根据那里使用的前缀覆盖它自己的 namespace ，包括它使用的 namespace 发送 SOAP 信封本身。

解决方案是使用 envprefix 方法让它为 SOAP 信封使用不同的命名空间前缀。例如:

my $service = SOAP::Lite->service($url)->soapversion('1.1')->envprefix('S');
