android 特殊手機終端創建一個服務器 對外公開地址（生成一個二維碼的地址） 掃碼識別點開爲一個web 頁面，可以下載本地的相關資源 或者播放本地的資源
android 服務器播放視頻
其實都大同小異
也可以這種搭建服務器
AndServer，一個Android端的web服務器
這種比較繁瑣
我的包直接用的 [android 服務器播放視頻] 項目裏面的lib
package com.pad.ui.activity.progressbar;
import android.util.Log;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.List;
import fi.iki.elonen.NanoHTTPD;
import fi.iki.elonen.NanoHTTPD.Response.Status;
public class FileServer extends NanoHTTPD{
public static final int DEFAULT_SERVER_PORT= 8080;//爲8080
public static final String TAG = FileServer.class.getSimpleName();
//根目錄
private static final String REQUEST_ROOT = "/";
private List<SharedFile> fileList;//用於分享的文件列表
public FileServer(List<SharedFile> fileList) {
super(DEFAULT_SERVER_PORT);
this.fileList = fileList;
}
@Override
public Response serve(IHTTPSession session) {
Log.d(TAG,"OnRequest: "+session.getUri());
if(REQUEST_ROOT.equals(session.getUri())||session.getUri().equals("")){
return responseRootPage(session);
}
return responseFile(session);
// return response404(session,session.getUri());
}
//對於請求根目錄的，返回分享的文件列表
public Response responseRootPage(IHTTPSession session) {
StringBuilder builder = new StringBuilder();
builder.append("<!DOCTYPER html><html><body>");
builder.append("<ol>");
for (int i = 0, len = fileList.size(); i < len; i++) {
File file = new File(fileList.get(i).getPath());
if (file.exists()) {
//文件及下載文件的鏈接，定義了一個文件類，這裏使用getPath方法獲得路徑，使用getName方法獲得文件名
builder.append("<li> <a href=\"" + file.getPath() + "\">" + file.getName() + "</a></li>");
}
}
builder.append("<li>File Size： " + fileList.size() + "</li>");
builder.append("</ol>");
builder.append("</body></html>\n");
//回送應答
return new Response(String.valueOf(builder));
}
//對於請求文件的，返回下載的文件
public Response responseFile(IHTTPSession session){
try {
//uri：用於標示文件資源的字符串，這裏即是文件路徑
String uri = session.getUri();
FileInputStream fis = new FileInputStream(uri);
return new Response(Status.OK,"application/octet-stream",fis);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
return response404(session,null);
}
public Response response404(IHTTPSession session,String url) {
StringBuilder builder = new StringBuilder();
builder.append("<!DOCTYPE html><html><body>");
builder.append("Sorry, Can't Found "+url + " !");
builder.append("</body></html>\n");
return new Response(builder.toString());
}
}
activity 主要實現 服務的開啓與關閉 隨帶吧url 生成二維碼方便外部訪問下載 （同一局域網訪問下載）
private static final String DEFAULT_FILE_PATH = Environment.getExternalStorageDirectory() + "/movie.mp4";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ipStr = getIpAddress(ProgressBarActivity.this);
String macStr = getMacAddressFromIp(ProgressBarActivity.this);
showIp.setText("IP : " + ipStr);
mVideoServer = new VideoServer(DEFAULT_FILE_PATH, VIDEO_WIDTH, VIDEO_HEIGHT, VideoServer.DEFAULT_SERVER_PORT);
showIp.setText("請在遠程瀏覽器中輸入:\n\n" + ipStr + ":" + VideoServer.DEFAULT_SERVER_PORT);
List<SharedFile> sharedFileList = new ArrayList<>();
SharedFile sharedFile = new SharedFile();
sharedFile.setName("movie.mp4");
sharedFile.setPath(DEFAULT_FILE_PATH);
sharedFileList.add(sharedFile);
SharedFile sharedFile01 = new SharedFile();
sharedFile01.setName("人員.xlsx");
sharedFile01.setPath(Environment.getExternalStorageDirectory() + "/mo.xlsx");
sharedFileList.add(sharedFile01);
fileServer = new FileServer(sharedFileList);
handler.post(new Runnable() {
@Override
public void run() {
Bitmap qrccode = QRCodeEncoder.syncEncodeQRCode(ipStr + ":" + VideoServer.DEFAULT_SERVER_PORT+
DEFAULT_FILE_PATH,400);
// Bitmap qrccode = QRCodeEncoder.syncEncodeQRCode(ipStr + ":" + VideoServer.DEFAULT_SERVER_PORT,200);
showZxing.setImageBitmap(qrccode);
}
});
@Override
protected void onDestroy() {
mVideoServer.stop();
fileServer.stop();
super.onDestroy();
}
}
手機端 或者網頁端直接
http://10.67.13.209:8080/ 類似這種可以看到列表 然後點擊可以下載資源
http://10.67.13.209:8080/storage/emulated/0/mo.xlsx
類似這種可以直接下載資源到本地
這個 視頻播放 網頁端播放視頻流
我們N多年前對終端的數據做處理，增刪改的操作可以這樣做
@Deprecated
public Response serve(IHTTPSession session) {
try {
if (Method.POST.equals(session.getMethod())) {
String uri = session.getUri();
fields = session.getParms();
session.parseBody(fields);

switch (uri) {
case "/SendQRPayAddress":
receiveAddress();
break;

}
}
根據不同的url 做具體的也業務處理
這次有用到了，做個記錄省的下次再查看，方便直接用到項目中
根據業務需要是一直開着，還是在適當的時候開啓服務，自己看着處理
