這篇“php調(diào)用webservice失敗怎么解決”文章的知識(shí)點(diǎn)大部分人都不太理解,所以小編給大家總結(jié)了以下內(nèi)容,內(nèi)容詳細(xì),步驟清晰,具有一定的借鑒價(jià)值,希望大家閱讀完這篇文章能有所收獲,下面我們一起來看看這篇“php調(diào)用webservice失敗怎么解決”文章吧。
php調(diào)用webservice失敗的解決辦法:1、去掉“;extension=php_soap.dll”前的分號(hào)并重啟apache;2、創(chuàng)建WSDL文件并運(yùn)行creatService.php文件;3、關(guān)閉WSDL緩存。
本文操作環(huán)境:windows7系統(tǒng)、PHP7.1版、DELL G3電腦
php調(diào)用webservice失敗怎么辦?
php編寫webservice案例、webservice調(diào)用失敗
作為開發(fā)者來講,要想寫webservice接口或者調(diào)用別人的webservice接口,首先需要了解什么是webservice。
簡(jiǎn)單說, WebService就是一些站點(diǎn)開放一些服務(wù)出來, 也可以是你自己開發(fā)的Service, 也就是一些方法, 通過URL,指定某一個(gè)方法名,發(fā)出請(qǐng)求,站點(diǎn)里的這個(gè)服務(wù)(方法),接到你的請(qǐng)求,根據(jù)傳過來的參數(shù),做一些處理,然后把處理后的結(jié)果以XML形式返回來給你,你的程序就解析這些XML數(shù)據(jù),然后顯示出來或做其它操作。
在開始編寫之前需要對(duì)php環(huán)境做一些配置:
打開php安裝目錄下的php.ini文件
找到 ;extension=php_soap.dll ,去掉前面的分號(hào),保存,然后重啟apache。
配置好環(huán)境就可以編寫php了,先創(chuàng)建creatService.php文件,復(fù)制下面代碼:
<?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 '數(shù)據(jù)庫連接失敗。'; exit; } $result=$db->query("insert into test_soap (text) values('".$text."')"); if($result){ return $result; }else{ return "插入失敗"; } } } if(file_exists('ServiceTest.wsdl')){ //只有當(dāng)ServiceTest.wsdl文件存在時(shí)才進(jìn)行注冊(cè)類 $objSoapServer = new SoapServer("ServiceTest.wsdl"); //注冊(cè)ServiceTest類的所有方法 $objSoapServer->setClass("ServiceTest"); //處理請(qǐng)求 $objSoapServer->handle(); } require_once "SoapDiscovery.class.php"; $dis=new SoapDiscovery("ServiceTest","WebService"); //第一個(gè)參數(shù)為類名也是生成wsdl的文件名 $dis->getWSDL(); ?>
第一次運(yùn)行creatService.php文件時(shí)要?jiǎng)?chuàng)建wsdl文件,創(chuàng)建WSDL文件需要用到一個(gè)輔助類SoapDiscovery.class.php。在文章末尾可以得到。
創(chuàng)建完成之后便是測(cè)試調(diào)用,創(chuàng)建client.php文件,復(fù)制以下代碼:
ini_set('soap.wsdl_cache_enabled','0');//關(guān)閉緩存 $x = new SoapClient("http://localhost/webServiceTest/ServiceTest.wsdl"); //這里的鏈接換成你自己的訪問鏈接 try { echo $x->firstHandle('qweqrwergwe'); echo ('<pre>'); var_dump ( $x->__getFunctions () );//獲取服務(wù)器上提供的方法 echo ('</pre>'); echo ('<pre>'); var_dump ( $x->__getTypes () );//獲取服務(wù)器上數(shù)據(jù)類型 echo ('</pre>'); }catch (SoapFault $f){ echo "Error Message: {$f->getMessage()}"; }
注意! ini_set('soap.wsdl_cache_enabled','0'); //關(guān)閉WSDL緩存
如果不關(guān)閉緩存,會(huì)造成測(cè)試無效,緩存數(shù)據(jù)會(huì)擾亂測(cè)試準(zhǔn)確性。
注意!如果是在thinkphp5中使用SoapClient函數(shù)應(yīng)當(dāng)如下使用:
$client = new \SoapClient ('http://www.baidu.com/ids/terminal/terminalWs.wsdl');
重要點(diǎn):
使用https訪問webservice的話會(huì)出現(xiàn)訪問異常,博主就遇到這個(gè)問題的,本地創(chuàng)建和調(diào)用webservice都通過了,但是一放到線上就無法調(diào)用了,然后各種google、baidu。最后才發(fā)現(xiàn)線上的環(huán)境是http強(qiáng)制轉(zhuǎn)了https。
我的解決辦法是取消了http強(qiáng)制轉(zhuǎn)換https的功能:
找到httpd-vhost.conf,注釋掉一下代碼:
## RewriteEngine on ## RewriteCond %{HTTPS} !=on ## RewriteRule ^(.*) https://%{SERVER_NAME}$1 [L,R]
注釋掉上面的代碼后我發(fā)現(xiàn)我的網(wǎng)站不是https了,嗚嗚嗚~,真的是拆了東墻補(bǔ)西墻啊,趕緊想辦法,因?yàn)榫W(wǎng)站必須使用https才行,還好我使用的是thinkphp框架,找到了一個(gè)方法,在入口文件index.php最下面加入下面的代碼就行了:
if (empty($_SERVER['HTTPS']) || $_SERVER['HTTPS'] === "off") { $location = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; header('HTTP/1.1 301 Moved Permanently'); header('Location: ' . $location); exit; }
