将上述地址配置到指定文件即可.

需要留意版本，本人就还是在用android 4.1 cordova 用的是2.8版本，所以稍微麻烦了点

莫鄙视…

DISCUZ 特殊积分解决方案

最近discuz有个小功能需求，需要实现送某某积分的操作，但是是对外的。不可进行其它操作。下面用B积分进行表示

只是需要在积分日志列表上进行显示，但是又不可对该积分进行操作。考虑到不影响discuz的系统.使用扩展积分8类型，但是该积分是关闭状态，无法进行其它操作。

送B积分时,使用类型参数8进行标志。如:

							updatemembercount ( array (
									// 用户id
							), array (
									8 => $score  //分值
							), true, '', 1, '', '标题','内容描述' );

然后前台显示时，在插件钩子处，挂上类型8的显示，只在特殊地方进行显示。别的地方调用时，也不会出现什么影响

如:

class plugin_xxxxx_home extends plugin_gd_jifen {
	function spacecp_credit_extra() {
			$_G ['setting'] ['extcredits'] [8] = array (
					'img' => '',
					'title' => 'B积分',
					'unit' => '',
					'ratio' => 0,
					'showinthread' => '0',
					'allowexchangein' => '',
					'allowexchangeout' => '',
					'hiddeninheader' => true 
			);
	}
}

前台显示赠送的B积分提示

原理:http://witmax.cn/discuz-credits-analysis.html

但是具体要提示的，需要补充下面的代码:

$_G ['setting'] ['creditnames'] .= ',8|B|';

页面通过判断html里是否有该标志进行对应的提示

soap 超时处理

class SoapClientX extends SoapClient {
	private $timeout;
	function __construct($wdsl, $options = array()) {
		// 考虑到不和原函数冲突.
		if (isset ( $options ['timeout'] )) {
			$this->timeout = intval ( $options ['timeout'] );
		} else {
			$this->timeout = 10;
		}
		parent::__construct ( $wdsl, $options );
	}
	public function __doRequest($request, $location, $action, $version, $one_way = false) {
		ini_set ( 'default_socket_timeout', $this->timeout );
		try {
			// 当超时返回空时，表示非正常报文返回，出现"Error Fetching http headers"异常
			$response = parent::__doRequest ( $request, $location, $action, $version, $one_way );
		} catch ( Exception $e ) {
			if (stristr ( $e->getMessage (), "Error Fetching http headers" )) {
				throw new SoapFault ( 'timeout', "请求超时" );
			}
		}
		if (! $response) {
			throw new SoapFault ( 'timeout', "请求超时" );
		}
		return ($response);
	}
}

 

看完 新概念二册

前几天刚看完第二册。

先看中文，翻译回英文，再去看课文的方式对内容的印象相当深，不过也花了不少时间。不过值了~

现在听朋友球的建议，巩固。从第一册到第二册重新过，然后按 先翻译再看课文的方式学习，加深印象，巩固基础。再去看第三册。

里面的老师说了句很实在的话:

英语这门语言，并不一定越理解越用得好，还是需要经常锻炼来熟悉它。

继续继续~
