【问题描述】:
我在尝试使用 PHP 使用 SOAP 服务时遇到了一个奇怪的问题。它忽略了我的请求,并不断返回最后一个命令的结果! SOAP 驻留在收银机中,它有一个指向公共 IP 端点的“错误”wsdl,我不得不手动编辑它。 WSDL 文件位于我下载的http://192.168.1.20/MyEcrResponce.wsdl 中,并将所有错误的 IP 引用替换为“192.168.1.20”,然后我将其保存为本地 MyEcrResponce.wsdl:

我在 C# 中使用表单创建了一个客户端,将解决方案中的所有引用从公共 IP 替换为 192.168.1.20,并且工作正常:
private void button1_Click(object sender, EventArgs e)
{
string reply = "";
string LcdMsg1 = "";
string LcdMsg2 = "";
Uri ur = new Uri("http://192.168.1.20/MyEcrResponce.cgx");
DeviceWS.MyEcrResponceSoapClient DevHD = new DeviceWS.MyEcrResponceSoapClient();
DevHD.Endpoint.Address = new System.ServiceModel.EndpointAddress(ur);
DevHD.ClientCredentials.UserName.UserName = "user";
DevHD.ClientCredentials.UserName.Password = "pass";
reply = DevHD.Cmd(CmdTxt.Text, out LcdMsg1, out LcdMsg2);
ReplyTxt.Text = reply;
LCD01.Text = LcdMsg1;
LCD02.Text = LcdMsg2;
}
我的 PHP 客户端如下所示:
$client = new SoapClient(
dirname(__FILE__) . DIRECTORY_SEPARATOR . 'MyEcrResponce.wsdl',
array('location' => 'http://192.168.1.20/MyEcrResponce.cgx',
'login' => 'user',
'password' => 'pass',
'trace' => 0,
'cache_wsdl' => WSDL_CACHE_NONE));
$cmd = new StdClass();
$cmd->CmdText = 'a/';
var_dump($client->Cmd($cmd));
无论我尝试哪种组合,在 PHP 中我总是得到 C# 客户端命令的最后一个结果。似乎所有使用 PHP 的请求都被忽略了。似乎有一个 C# 可以超越的缓存,但 PHP 不能。在 php.ini 中,'soap.wsdl_cache_enabled' 和 'soap.wsdl_cache' 都设置为 0。SoapUI 和其他 SOAP 测试仪的行为相同(错误)。有什么想法吗?
更新 1: PHP $client->__getTypes();返回:
array (4) [
string (31) "struct Cmd {
string CmdText;
}"
string (76) "struct CmdResponse {
string CmdReply;
string LcdLine1;
string LcdLine2;
}"
string (58) "struct GetAppStatus {
string SerialNo;
string RetData;
}"
string (82) "struct GetAppStatusResponse {
unsignedByte GetAppStatusResult;
string RetData;
}"
]
更新 2: 使用 this post 我在 C# 客户端中启用了跟踪日志来检查正在工作的 SOAP 请求,这是一个:
{
Content-Type: text/xml; charset=utf-8
SOAPAction: "http://192.168.1.20/Cmd"
Accept-Encoding: gzip, deflate,gzip, deflate
Authorization: Basic xxxxxxxxxxxxxxxx
Host: 192.168.1.20
Content-Length: 207
Expect: 100-continue
}
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<Cmd xmlns="http://192.168.1.20/" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<CmdText>a/</CmdText>
</Cmd>
</s:Body>
</s:Envelope>
不幸的是,当我将请求复制粘贴到 PHP 或 SoapUI 时,结果仍然相同。
更新 3: 所以,今天是星期一。周五收银机和 PHP 服务器都关闭了,我今天打开了它们。在我运行 PHP 脚本之前,我从 PHP 服务器中清除了所有缓存文件,并且我收到了周五发送的最后一个成功命令的回复!!!我快要相信我必须非常愚蠢......
【问题讨论】:
-
试试 put ini_set('soap.wsdl_cache_enabled', '0'); ini_set('soap.wsdl_cache_ttl', '0');
-
我已经提到缓存被禁用了。
