php调用webservice失败怎么办？
php编写webservice案例、webservice调用失败
作为开发者来讲，要想写webservice接口或者调用别人的webservice接口，首先需要了解什么是webservice。
简单说, WebService就是一些站点开放一些服务出来, 也可以是你自己开发的Service, 也就是一些方法, 通过URL,指定某一个方法名,发出请求,站点里的这个服务(方法),接到你的请求,根据传过来的参数,做一些处理,然后把处理后的结果以XML形式返回来给你,你的程序就解析这些XML数据,然后显示出来或做其它操作。
在开始编写之前需要对php环境做一些配置：
打开php安装目录下的php.ini文件
找到 ;extension=php_soap.dll ，去掉前面的分号，保存，然后重启apache。
配置好环境就可以编写php了，先创建creatService.php文件，复制下面代码：
<?php
class ServiceTest{
public function firstHandle($name){
return "你的名字是:".$name;
}
public function dbInsert($text){
$db=new mysqli("localhost","root","","test");
if(mysqli_connect_error()){
return '数据库连接失败。';
exit;
}
$result=$db->query("insert into test_soap (text) values('".$text."')");
if($result){
return $result;
}else{
return "插入失败";
}
}
}
if(file_exists('ServiceTest.wsdl')){ //只有当ServiceTest.wsdl文件存在时才进行注册类
$objSoapServer = new SoapServer("ServiceTest.wsdl");
//注册ServiceTest类的所有方法
$objSoapServer->setClass("ServiceTest");
//处理请求
$objSoapServer->handle();
}
require_once "SoapDiscovery.class.php";
$dis=new SoapDiscovery("ServiceTest","WebService"); //第一个参数为类名也是生成wsdl的文件名
$dis->getWSDL();
?>第一次运行creatService.php文件时要创建wsdl文件，创建WSDL文件需要用到一个辅助类SoapDiscovery.class.php。在文章末尾可以得到。
创建完成之后便是测试调用，创建client.php文件，复制以下代码：
ini_set('soap.wsdl_cache_enabled','0');//关闭缓存
$x = new SoapClient("http://localhost/webServiceTest/ServiceTest.wsdl"); //这里的链接换成你自己的访问链接
try {
echo $x->firstHandle('qweqrwergwe');
echo ('<pre class="brush:php;toolbar:false">');
var_dump ( $x->__getFunctions () );//获取服务器上提供的方法
echo ('');
echo ('');
var_dump ( $x->__getTypes () );//获取服务器上数据类型
echo ('');
}catch (SoapFault $f){
echo "Error Message: {$f->getMessage()}";
}注意！ ini_set('soap.wsdl_cache_enabled','0'); //关闭WSDL缓存
如果不关闭缓存，会造成测试无效，缓存数据会扰乱测试准确性。
注意！如果是在thinkphp5中使用SoapClient函数应当如下使用：
$client = new \SoapClient ('http://www.baidu.com/ids/terminal/terminalWs.wsdl');
重要点：
使用https访问webservice的话会出现访问异常，博主就遇到这个问题的，本地创建和调用webservice都通过了，但是一放到线上就无法调用了，然后各种google、baidu。最后才发现线上的环境是http强制转了https。
我的解决办法是取消了http强制转换https的功能：
找到httpd-vhost.conf，注释掉一下代码：
## RewriteEngine on
## RewriteCond %{HTTPS} !=on
## RewriteRule ^(.*) https://%{SERVER_NAME}$1 [L,R]注释掉上面的代码后我发现我的网站不是https了，呜呜呜~，真的是拆了东墙补西墙啊，赶紧想办法，因为网站必须使用https才行，还好我使用的是thinkphp框架，找到了一个方法，在入口文件index.php最下面加入下面的代码就行了：
if (empty($_SERVER['HTTPS']) || $_SERVER['HTTPS'] === "off") {
$location = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
header('HTTP/1.1 301 Moved Permanently');
header('Location: ' . $location);
exit;
}
