在php上创建web服务

我正在尝试创建一个web服务，但我无法理解这里的问题是什么

SimpleClient.php

 <?php
include_once("nusoap.php");

try {

// Create a soap client using SoapClient class
// Set the first parameter as null, because we are operating in non-WSDL mode.
// Pass array containing url and uri of the soap server as second parameter.
$client = new SoapClient(null, array(
'location' => "http://www.example.com/SimpleServer.php",
'uri' => "http://www.example.com"));
// Read request parameter
$param = $_POST['name'];
// Invoke AddHello() method of the soap server (HelloServer)
$result = $client->AddHello($param);
echo $result; // Process the the result
echo "test";
}
catch(SoapFault $ex) {
$ex->getMessage();
echo 'test';
}
?>

SimpleServer.php

    <?php
include_once("nusoap.php");

// Simple Method get 1 parameter and return with Hello
function AddHello($name)
{
     return "Hello $name";
}
// Create SoapServer object using WSDL file.
// For the simplicity, our SoapServer is set to operate in non-WSDL mode. So we do not need a WSDL file
$server = new SoapServer(null, array('uri'=>'http://www.example.com'));
// Add AddHello() function to the SoapServer using addFunction().
$server->addFunction("AddHello");
// To process the request, call handle() method of SoapServer.
$server->handle();
?> 

SimpleView.php

  <?php
echo "<h2>Welcome to PHP Web Service</h2>";
echo "<form action='SimpleClient.php' method='POST'/>";
echo "<input name='name' /><br/>";
echo "<input type='Submit' name='submit' value='Send'/>";
echo "</form>";
?>

我查看了您参考的教程，它对我很有用
只需下载他们提供的代码并在中更改uri参数
SimpleClient.php文件

如果apache服务器托管在端口80之外，请正确指定该端口

我从那里下载了代码并粘贴到了webroot目录中
网络服务目录

因此SimpleClient.php与端口80类似

<?php
try {
// Create a soap client using SoapClient class
// Set the first parameter as null, because we are operating in non-WSDL mode.
// Pass array containing url and uri of the soap server as second parameter.
$client = new SoapClient(null, array(
'location' => "http://localhost/Web_Service/SimpleServer.php",
'uri' => "http://localhost/Web_Service/"));
// Read request parameter
$param = $_POST['name'];
// Invoke AddHello() method of the soap server (HelloServer)
$result = $client->AddHello($param);
echo $result; // Process the the result
}
catch(SoapFault $ex) {
$ex->getMessage();
}
?>



如果您的服务器托管在不同的端口中，请指定如下端口。
这里我提到了81端口

<?php
try {
// Create a soap client using SoapClient class
// Set the first parameter as null, because we are operating in non-WSDL mode.
// Pass array containing url and uri of the soap server as second parameter.
$client = new SoapClient(null, array(
'location' => "http://localhost:81/Web_Service/SimpleServer.php",
'uri' => "http://localhost:81/Web_Service/"));
// Read request parameter
$param = $_POST['name'];
// Invoke AddHello() method of the soap server (HelloServer)
$result = $client->AddHello($param);
echo $result; // Process the the result
}
catch(SoapFault $ex) {
$ex->getMessage();
}
?>

在SimpleServer中：在使用AddHello函数之前，您需要对其进行重新设置

$server->register('AddHello',$name)

您是否关闭了PHP错误？如果您看到的是一个空白屏幕，这可能意味着PHP抛出了一个致命错误，但由于配置设置的原因，正在抑制该错误。打开错误消息，您将看到更多信息，以帮助您调试问题。（或者查看服务器日志文件，它将包含相同的信息）很抱歉，它的错误\u reporting=30711:Salso，我注意到您正在使用NuSoap库。您是否知道PHP有自己的内置Soap类，使NuSoap变得多余。请看，我在过去创建了一个库，它生成WSDL文档并处理入/出soap消息。这很简单，您可以查看以下URL：
