PHP：从 Java 调用 SOAP rpc webservice 时出错 - 之前工作过

Question

我有一个 java 程序，它通过 SOAP 调用 php (rpc) 中的方法。几天后，它不再适用于我现有的代码。在我的开发机器上，我最近更新到 php7.0，但在远程服务器上仍然有 php5.x 运行。它既不适用于本地主机，也不适用于远程服务器。两台机器都是运行 Ubuntu (dev 16.04, remote 14.04)

我总是收到以下错误：

[SOAPException: faultCode=SOAP-ENV:Client; msg=Parsing error, response was:
The processing instruction target matching &quot;[xX][mM][lL]&quot; is not allowed.; targetException=org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 6; 
The processing instruction target matching "[xX][mM][lL]" is not allowed.]

我用 SOAP UI 测试过，它有效，没有错误。我什至用 apache axis2 测试过，但也失败了。

问题是来自 php 脚本的响应似乎无效。

我查看了编码等，检查是否有新行或其他内容。但我不知道问题可能是什么。

在 Soap 中工作的示例 soap 调用 UI:

<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Body>
<ns1:searchQuery xmlns:ns1="http://localhost/Server.php" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<query xsi:type="xsd:string">oil</query>
</ns1:searchQuery>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

响应：当我在 Soap UI 中单击验证时，它告诉我 xml 声明格式不正确。但是我不知道怎么改。

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://localhost/Server.php" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body><ns1:searchQueryResponse><return xsi:type="xsd:string">{
  "prefixes": ..... }
</return></ns1:searchQueryResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>

我用来初始化 soap 服务器的 php 代码：

try {

    ini_set ( "soap.wsdl_cache_enabled", "0" );
    $server = new SOAPServer ( 'Server.wsdl' );
    $server->setClass ( 'Webdienst' );
    $server->handle ();
} 

catch ( SOAPFault $f ) {
    echo $f->getMessage ();
}

我的 wsdl 文件：

<?xml version="1.0"?>
<definitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://localhost/Server.php" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" name="Webdienst" targetNamespace="http://localhost/Server.php">

Answer 1

谷歌搜索后我找到了解决方案。

问题是我的 soap 服务器 class 顶部有一个 include() 声明，其中包含另一个 php 文件。另一个 php 文件在 ?> 结束标记后有一个空行。我在最后一个大括号之后直接移动了结束标记，现在可以使用了！
