android设置打印机wifi(OKHttp+firefox的插件：HttpRequester+WireShake + servlet)。post和put提交。
通过android手机设置打印机的wifi步骤（爬虫）：
- 1.通过chrome捕获按钮所提交的请求数据
- 2.通过WireShark捕获所提交的请求数据
- 3.通过HttpRequester模拟浏览器提交请求数据
- 4.引用OkHttp实现模拟浏览器提交请求数据
- 5.(可不看)通过servlet查看post和put请求的数据
步骤1、2(先post后put)：
下面图的都是‘点击应用提交的是post请求’的截图（即打开打印机的wifi开关）：
由于上图的chrome找不到post的表单数据，所以借助WireShark抓包
下面的图是通过put方式提交wifi的账号和密码给服务器（这里的服务器指的是打印机）截图：
步骤3（HttpRequester插件模拟浏览器提交post和put请求）
HttpRequester插件提交post请求来打开打印机的wifi开关
HttpRequester插件提交put请求来提交wifi账号和密码
步骤4

步骤5 （通过servlet查看post和put请求的数据）
1.把client端的URL_POST改为：
private static String URL_POST = "http://localhost:8080/TestForm/FormServlet";2.servlet代码
import java.io.BufferedReader;
import java.io.IOException;
import java.util.Enumeration;
import java.util.Map;

import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class FormServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
System.out.println("get");
doPost(req, resp);
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
System.out.println("post");
System.out.println("content-length:" + req.getContentLength());
System.out.println("......................");
Enumeration<String> attrs = req.getAttributeNames();
String strAttr = "attributes:";
while(attrs.hasMoreElements()) {
strAttr = strAttr + attrs.nextElement() + ", ";
}
System.out.println(strAttr);
System.out.println("......................");
Enumeration<String> names = req.getHeaderNames();
String strName = "attribute names:";
while(names.hasMoreElements()) {
String headName = names.nextElement();
strName = strName + headName+ ":" + req.getHeader(headName) + ", ";
}
System.out.println(strName);
System.out.println("......................");
System.out.println("authType:" + req.getAuthType() + ", characterEncoding:" + req.getCharacterEncoding()

System.out.println("......................");
Map<String, String[]> paramsMaps = req.getParameterMap();
for(String key : paramsMaps.keySet()) {
String [] values = paramsMaps.get(key);
String strVal = "";
for(String str: values) {
strVal = strVal + str + ", ";
}
System.out.println("key=" + key +", values=" + strVal);
}
BufferedReader br = req.getReader();
System.out.println("======================");
System.out.println("bufferReader:");
String str = "";
while((str = br.readLine()) != null) {
System.out.println(str);
}
resp.sendRedirect(req.getContextPath()+"/haha.html");
}
@Override
protected void doPut(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
super.doPut(req, resp);
System.out.println("put");
System.out.println("content-length:" + req.getContentLength());
System.out.println("......................");
Enumeration<String> attrs = req.getAttributeNames();
String strAttr = "attributes:";
while(attrs.hasMoreElements()) {
strAttr = strAttr + attrs.nextElement() + ", ";
}
System.out.println(strAttr);
System.out.println("......................");
Enumeration<String> names = req.getHeaderNames();
String strName = "attribute names:";
while(names.hasMoreElements()) {
String headName = names.nextElement();
strName = strName + headName+ ":" + req.getHeader(headName) + ", ";
}
System.out.println(strName);
System.out.println("......................");
System.out.println("authType:" + req.getAuthType() + ", characterEncoding:" + req.getCharacterEncoding()
+", contentType:" + req.getContentType() + ", queryString:" + req.getQueryString());
System.out.println("......................");
Enumeration<String> params = req.getParameterNames();
String strParamNames = "params names:";

}
System.out.println("......................");
System.out.println(strParamNames);
System.out.println("......................");
Map<String, String[]> paramsMaps = req.getParameterMap();
for(String key : paramsMaps.keySet()) {
String [] values = paramsMaps.get(key);
String strVal = "";
for(String str: values) {
strVal = strVal + str + ", ";
}
System.out.println("key=" + key +", values=" + strVal);
}
BufferedReader br = req.getReader();
System.out.println("======================");
System.out.println("bufferReader:");
String str = "";
while((str = br.readLine()) != null) {
System.out.println(str);
}
resp.sendRedirect(req.getContextPath()+"/haha.html");
}
}
服务器收到的post请求数据如下：
post
content-length:73
......................

服务器收到的put请求数据如下：

结论：
从服务器收到的post和put的请求数据对比得出，put的xml字符串通过req.getReader()来读取，而post提交的表单则通过
Map<String, String[]> paramsMaps = req.getParameterMap();
for(String key : paramsMaps.keySet()) {
String [] values = paramsMaps.get(key);
String strVal = "";
for(String str: values) {
strVal = strVal + str + ", ";
}
System.out.println("key=" + key +", values=" + strVal);
}来获取。
