php调用webservice失败怎么办
时间：2022-02-11 13:57
php调用webservice失败的解决办法：1、去掉“;extension=php_soap.dll”前的分号并重启apache；2、创建WSDL文件并运行creatService.php文件；3、关闭WSDL缓存。 本文操作环境：windows7系统、PHP7.1版、DELL G3电脑 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： 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： 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： 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： 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： SoapDiscovery.class.php类： 推荐学习：《PHP视频教程》 以上就是php调用webservice失败怎么办的详细内容，更多请关注gxlsystem其它相关文章！
