php安装扩展Soap
最近PHP代码中在执行到$soapclient = new SoapClient('http://sdk.entinfo.cn:8060/webservice.asmx?WSDL'); 这条语句会抛出异常: Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://sdk.entinfo.cn:8060/webservice.asmx?WSDL' : Start tag expected, '<' not found in /ROOT/www/test.php:2 Stack trace
首先查看PHP是否安装了Soap扩展。查看phpinfo,可知安装了Soap扩展
根据异常的情况 判断,意思大概是连文档的Start tag没有读到, 1) 在浏览器中直接访问,发现是可以的, 2) curl也是可以的
1)于是用 file_get_contents(),获取内容,发现返回的是个空字符串。2) 于是检查 php.ini 中的 allow_url_open, 发现也是开这的3)遂进行如下测试:$file = fopen('http://www.example.com/', 'rb'); var_dump(stream_get_meta_data($file));
/* 输出结果: array(10) { ['wrapper_data']=> array(2) { ['headers']=> array(0) { } ['readbuf']=> resource(38) of type (stream) } ['wrapper_type']=> string(4) 'cURL' ['stream_type']=> string(4) 'cURL' ['mode']=> string(2) 'rb' ['unread_bytes']=> int(0) ['seekable']=> bool(false) ['uri']=> string(23) 'http://www.example.com/' ['timed_out']=> bool(false) ['blocked']=> bool(true) ['eof']=> bool(false) }*/
输出的结果中,wrapper_type为cURL,而且wrapper_data为空,这是不正常的,正常情况下wrapper_type应为 http,wrapper_data数组中应该包含响应头信息。发现这个现象与--with-curlwrappers这个编译选项有 关,遂查看PHP编译参数:$ php -i | grep configure
Configure Command => './configure' '--prefix=/usr/local/php' '--with-config-file-path=/usr/local/php/etc' '--with-mysql=/usr/local/mysql' '--with-mysqli=/usr/local/mysql/bin/mysql_config' '--with-iconv-dir=/usr/local' '--with-zlib' '--with-libxml-dir=/usr' '--enable-xml' '--enable-bcmath' '--enable-shmop' '--enable-sysvsem' '--enable-inline-optimization' '--with-curl' '--with-curlwrappers' '--enable-mbregex' '--enable-fpm' '--enable-mbstring' '--with-mcrypt' '--with-openssl' '--with-mhash' '--enable-pcntl' '--enable-sockets' '--with-xmlrpc' '--enable-zip' '--enable-soap' '--enable-bcmath'
--with-curlwrappers被启用了,问题应该出在这里,查看一下这个编译选项的用处:$ ./configure --help | grep curlwrappers --with-curlwrappers EXPERIMENTAL: Use cURL for url streams看来--with-curlwrappers这个编译选项是用来处理url stream的,不过前面有个硕大的EXPERIMENTAL字样,还在试验中。 现有的解决方法是重新编译PHP,去掉「--with-curlwrappers」:
1) $ cd /path/to/php-5.3.6 (切换到php安装目录)2) $ make clean (一定要make clean)3) $ ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql \ --with-mysqli=/usr/local/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-zlib \ --with-libxml-dir=/usr --enable-xml --enable-bcmath --enable-shmop --enable-sysvsem \ --enable-inline-optimization --with-curl --enable-mbregex --enable-fpm --enable-mbstring --with-mcrypt \ --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip \ --enable-soap --enable-bcmath -with-gd --with-jpeg-dir=/usr --with-png-dir=/usr --enable-gd-native-ttf 4) $ make && make install5) $ cd /usr/local/php/bin # 删除旧的PHP binary文件,并用新的进行替换,Mac下重新编译后会产生php.dSYM文件,其他Linux系统请自行处理 $ rm php && mv php.dSYM php6) 重启 php
完成后,再做个测试:$file = fopen('http://www.example.com/', 'rb'); var_dump(stream_get_meta_data($file));/* 结果如下:array(10) { ['wrapper_data']=> array(12) { [0]=> string(18) 'HTTP/1.0 302 Found' [1]=> string(46) 'Location: http://www.iana.org/domains/example/' [2]=> string(13) 'Server: BigIP' [3]=> string(17) 'Connection: close' [4]=> string(17) 'Content-Length: 0' [5]=> string(15) 'HTTP/1.1 200 OK' [6]=> string(35) 'Date: Sun, 18 Mar 2012 06:12:27 GMT' [7]=> string(29) 'Server: Apache/2.2.3 (CentOS)' [8]=> string(44) 'Last-Modified: Wed, 09 Feb 2011 17:13:15 GMT' [9]=> string(21) 'Vary: Accept-Encoding' [10]=> string(17) 'Connection: close' [11]=> string(38) 'Content-Type: text/html; charset=UTF-8' } ['wrapper_type']=> string(4) 'http' ['stream_type']=> string(14) 'tcp_socket/ssl' ['mode']=> string(2) 'rb' ['unread_bytes']=> int(1225) ['seekable']=> bool(false) ['uri']=> string(23) 'http://www.example.com/' ['timed_out']=> bool(false) ['blocked']=> bool(true) ['eof']=> bool(false) } */
wrapper_type变成了http,wrapper_data也被填充了,一切恢复正常。所以一条结论:慎用--with-curlwrappers
