偽造方法，參考代碼：

public class HelloA {private String large = new String(new char[100000]); public String getSubString() { return this.large.substring(0,2); } @Testpublic void test(){InputStream in = responseInputStream();try {if(in != null){FileOutputStream out = new FileOutputStream("C:\\Users\\User\\Desktop\\test.zip");writeInTxt(in,out);}} catch (FileNotFoundException e) {e.printStackTrace();} }public void writeInTxt(InputStream in, FileOutputStream out) {//char[] bytes = new char[1024];byte[] bytes = new byte[1024];int len = 0;try {//InputStreamReader isr = new InputStreamReader(in,"UTF-8");//OutputStreamWriter osw = new OutputStreamWriter(out,"UTF-8");while((len = in.read(bytes)) !=-1){out.write(bytes, 0, len);}} catch (IOException e) {e.printStackTrace();}}public InputStream responseInputStream(){InputStream in = null;/*String cookie="BAIDUID=4AB62207ED7EE9F7D5639F99FD2C93FB:FG=1; PSTM=1460857252; "+"BIDUPSID=187A5BC1E5DD0DEF05E21F73A29835EF; _5t_trace_sid=1ea40703c286c635041c90d9a5f70580; "+"_5t_trace_tms=1; H_PS_645EC=5b3dg%2Bo1fZjiciiEjCjOit34qHNoqmVzbHSdPYr%2FQo9iGTj%2BpjOjY0%2FE7%2Bo; "+"BD_CK_SAM=1; BD_HOME=0; H_PS_PSSID=19638_19289_1439_19713_19806_19559_19808_19843_19902_17001_15557_11849; BD_UPN=12314353";*/try {HttpURLConnection conn = (HttpURLConnection) new URL("http://www.baidu.com/").openConnection();conn.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.94 Safari/537.36)");conn.setRequestProperty("Accept-Encoding", "gzip, deflate, sdch");conn.setRequestProperty("referer", "http://www.baidu.com/");//conn.setRequestProperty("Cookie", cookie);conn.setRequestProperty("Accept-Language", "zh-CN,zh;q=0.8");conn.setRequestProperty("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");conn.setRequestMethod("GET");conn.setDoInput(true);int respcode=conn.getResponseCode();if(respcode == 200)in = conn.getInputStream();} catch (MalformedURLException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}return in;} }

????通過(guò)上述代碼就可以實(shí)現(xiàn)與HttpClient工具相似的功能，偽造referer來(lái)發(fā)送請(qǐng)求，獲取響應(yīng)，這里要注意的是返回的數(shù)據(jù)是zip格式的。或者直接寫(xiě)C:\\Users\\User\\Desktop\\test，test后面不帶zip等任何后綴，最后也能得到自己想要的響應(yīng)的數(shù)據(jù)。

????因此，分步走的頁(yè)面，比如員工注冊(cè)，分為三步走，第一步：校驗(yàn)識(shí)別號(hào)和用戶(hù)名，校驗(yàn)完成以后調(diào)到第二個(gè)頁(yè)面，校驗(yàn)手機(jī)號(hào)，手機(jī)號(hào)校驗(yàn)完成后，跳到第三個(gè)頁(yè)面輸入會(huì)員名的頁(yè)面完成注冊(cè)。為防止模擬器模擬參數(shù)請(qǐng)求，直接進(jìn)到第二個(gè)頁(yè)面，那么可以在后臺(tái)處理方法里面使用map來(lái)存儲(chǔ)，用戶(hù)名作為key，1或2作為value，再寫(xiě)一個(gè)攔截第二個(gè)和第三個(gè)頁(yè)面的過(guò)濾器。在doFilter方法里面，根據(jù)這個(gè)map的value值來(lái)判斷是不是第一個(gè)頁(yè)面轉(zhuǎn)過(guò)來(lái)的。
