本文主要是介绍android设置打印机wifi(OKHttp+firefox的插件:HttpRequester+WireShake + servlet),希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
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
1.导包
compile 'com.squareup.okhttp3:okhttp:3.9.0'
2.java实现
import java.io.IOException;import okhttp3.FormBody;
import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;/*** Created by shixing on 2017/11/1.*/public class NetworkSetting {private static final OkHttpClient mOkHttpClient = new OkHttpClient();private static final String URL_POST = "http://192.168.223.1/hp/device/config_result_YesNo.html/config";private static final String URL_PUT = "http://192.168.223.1/IoMgmt/Adapters/wifi0/Profiles/Active";static final MediaType XML = MediaType.parse("application/xml");//打开wifi开关public static String postData() {FormBody.Builder formBodyBuilder = new FormBody.Builder();formBodyBuilder.add("Clear", "\346\230\257");formBodyBuilder.add("Menu", "NetWifiChange");formBodyBuilder.add("Configuration", "WifiEnabled=1");RequestBody requestBody = formBodyBuilder.build();Request request = new Request.Builder().addHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8").addHeader("Accept-Encoding", "gzip, deflate").addHeader("Accept-Language", "zh-CN,zh;q=0.8").addHeader("Cache-Control", "max-age=0").addHeader("Connection", "keep-alive").addHeader("Content-Type", "application/x-www-form-urlencoded").addHeader("Host", "192.168.223.1").addHeader("Origin", "http://192.168.223.1").addHeader("Referer", "http://192.168.223.1/hp/device/config_result_YesNo.html?tab=Networking&menu=NetWifiChange&WifiEnabled=1").addHeader("Upgrade-Insecure-Requests", "1").addHeader("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36").url(URL_POST).post(requestBody).build();try {Response response = mOkHttpClient.newCall(request).execute();Log.d(MainActivity.TAG, "postData: " + response.code());return response.body().string();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}return null;}//把用户名和密码以一个xml字符串的形式put到打印机(这里的打印机就是服务器)上public static String putMyData() {RequestBody requestBody = RequestBody.create(XML,getXml());Request request = new Request.Builder().url(URL_PUT).addHeader("Accept","application/xml, text/xml, */*").addHeader("Accept-Encoding","gzip, deflate").addHeader("Connection","keep-alive").addHeader("Accept-Language","zh-CN,zh;q=0.8").addHeader("Host","192.168.223.1").addHeader("Origin","http://192.168.223.1").addHeader("Referer","http://192.168.223.1/set_config_network_Wireless.html?tab=Networking&menu=NetWireless").addHeader("User-Agent","Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36").addHeader("X-Requested-With","XMLHttpRequest").put(requestBody).build();try {Response response = mOkHttpClient.newCall(request).execute();Log.d(MainActivity.TAG, "putMyData: " + response.code());return response.body().string();} catch (IOException e) {e.printStackTrace();}return null;}private static String getXml() {return "<?xml version:\"1.0\" encoding=\"UTF-8\" ?><io:Profile xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:dd=\"http://www.hp.com/schemas/imaging/con/dictionaries/1.0/\" xmlns:io=\"http://www.hp.com/schemas/imaging/con/ledm/iomgmt/2008/11/30\" xmlns:wifi=\"http://www.hp.com/schemas/imaging/con/wifi/2009/06/26\" xmlns:ipdyn=\"http://www.hp.com/schemas/imaging/con/ledm/internalprintdyn/2008/03/21\" ><io:AdapterProfile><io:WifiProfile><wifi:SSID>646C696E6B</wifi:SSID> <wifi:CommunicationMode>infrastructure</wifi:CommunicationMode> <wifi:EncryptionType>WPA_PSK</wifi:EncryptionType><wifi:AuthenticationMode>WPA_PSK</wifi:AuthenticationMode><io:KeyInfo><io:WpaPassPhraseInfo><wifi:RsnEncryption>AESOrTKIP</wifi:RsnEncryption><wifi:RsnAuthorization>autoWPA</wifi:RsnAuthorization><wifi:PassPhrase>6E686C323230323230</wifi:PassPhrase></io:WpaPassPhraseInfo></io:KeyInfo></io:WifiProfile></io:AdapterProfile></io:Profile>";}
}
MainActivity.java(不要在ui线程访问网络)
public class MainActivity extends AppCompatActivity {public static final String TAG = "MainActivity";@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);new Thread() {@Overridepublic void run() {Log.d(TAG, "run: " + NetworkSetting.postData());Log.d(TAG, "run: " + NetworkSetting.putMyData());}}.start();}
}
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.ServletException;
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 {@Overrideprotected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {System.out.println("get");doPost(req, resp);}@Overrideprotected 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()+", contentType:" + req.getContentType() + ", queryString:" + req.getQueryString());System.out.println("......................");Enumeration<String> params = req.getParameterNames();String strParamNames = "params names:";while(params.hasMoreElements()) {strParamNames = strParamNames + params.nextElement() + ", ";}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");}@Overrideprotected 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:";while(params.hasMoreElements()) {strParamNames = strParamNames + params.nextElement() + ", ";}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");}
}

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。
