代码记事本        记录过往云烟首页关于android HttpClient utf-8中文乱码问题今天在android上用HttpClient接口进行网络访问，在HttpEntity中已经设置编码为utf-8了，而被请求的页面也设置了，所有的代码文件编码也为utf-8，但请求后返回的结果显示仍为乱码，查阅资料后发现是在用EntityUtils.toString()取得返回字符串的时候，默认编码为ISO-8859-1，需要指定toString的第二个参数为utf-8，问题得以解决。部分代码：String httpUrl = "http://10.0.2.2/data.php";HttpPost httpRequest = new HttpPost(httpUrl);List params = new ArrayList();params.add(new BasicNameValuePair("param", "你好 HttpClient_Post"));try {HttpEntity httpEntity = new UrlEncodedFormEntity(params, "UTF-8");httpRequest.setEntity(httpEntity);HttpClient httpClient = new DefaultHttpClient();HttpResponse httpResponse = httpClient.execute(httpRequest);if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {String result = EntityUtils.toString(httpResponse.getEntity(), "UTF-8");textview.setText(result);} else {textview.setText("请求错误");}} catch (ClientProtocolException e) {textview.setText(e.getMessage().toString());} catch (IOException e) {textview.setText(e.getMessage().toString());} catch (Exception e) {textview.setText(e.getMessage().toString());}No Reply , Posted in 杂七杂八 on July 22, 2013Could not open the editor: Invalid thread accessMyeclipse安装了SVN插件之后突然打开什么东西都报错了：Could not open the editor: Invalid thread access解决方法是：1. cmd2. cd 进入你的Myeclipse安装目录 ： E:\MyEclipse8.5>3.执行命令  -clean   比如：我的安装目录下是Myeclipse.exe则执行： Myeclipse.exe -cleanNo Reply , Posted in java on June 12, 2013win8 添加开机启动C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUpNo Reply , Posted in 杂七杂八 on June 12, 2013Linux 常用netstat命令 实例讲解这是一个十分常用的命令，可以让你实时了解到云主机当前的状态，例如：常见的80连接数量，以及按一些排序，来检查是否被攻击？查看time_wait和syn连接数量等等。1.查看所有80端口的连接数netstat -nat|grep -i "80"|wc -l
2.对连接的IP按连接数量进行排序netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n
3.查看TCP连接状态netstat -nat |awk '{print $6}'|sort|uniq -c|sort -rn
netstat -n | awk '/^tcp/ {++S[$NF]};END {for(a in S) print a, S[a]}'
netstat -n | awk '/^tcp/ {++state[$NF]}; END {for(key in state) print key,"\t",state[key]}'
netstat -n | awk '/^tcp/ {++arr[$NF]};END {for(k in arr) print k,"\t",arr[k]}'
netstat -n |awk '/^tcp/ {print $NF}'|sort|uniq -c|sort -rn
netstat -ant | awk '{print $NF}' | grep -v '[a-z]' | sort | uniq -c
4.查看80端口连接数最多的20个IPnetstat -anlp|grep 80|grep tcp|awk '{print $5}'|awk -F: '{print $1}'|sort|uniq -c|sort -nr|head -n20
netstat -ant |awk '/:80/{split($5,ip,":");++A[ip[1]]}END{for(i in A) print A,i}' |sort -rn|head -n20
5.用tcpdump嗅探80端口的访问看看谁最高tcpdump -i eth0 -tnn dst port 80 -c 1000 | awk -F"." '{print $1"."$2"."$3"."$4}' | sort | uniq -c | sort -nr |head -20
6.查找较多time_wait连接netstat -n|grep TIME_WAIT|awk '{print $5}'|sort|uniq -c|sort -rn|head -n20
7.找查较多的SYN连接netstat -an | grep SYN | awk '{print $5}' | awk -F: '{print $1}' | sort | uniq -c | sort -nr | more

几个Log
log4j、logback、log4j2的恩怨情仇：log4j作者Ceki Gülcü不满Apache的工作方式，自己拉杆子搞了间公司，捣鼓出slf4j和logback，靠卖文档、培训和服务为生。然后Apache的家伙觉得logging不该掌握在一间公司手里，以社区驱动搞了log4j2，学习logback的同时也在鸡蛋里猛挑骨头，现在出到Beta3版
