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：
<?phpclass 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>'); var_dump ( $x->__getfunctions () );//获取服务器上提供的方法 echo ('</pre>'); echo ('<pre>'); var_dump ( $x->__gettypes () );//获取服务器上数据类型 echo ('</pre>');}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;}
