问题描述
我想使用NanoHTTP来提供一个HTML文件。然而,NanoHTTP相对未记录在案,而我是新来的机器人。我的问题是,我在哪里保存的HTML文件,以及如何具体可以用NanoHTTP我为它服务了。
I am trying to use NanoHTTP to serve up an HTML file. However, NanoHTTP is relatively un-documented, and I am new to Android. My question is, where do I store the html file, and how specifically can I serve it up using NanoHTTP.
推荐答案
一个迟到的答案,但可能对别人有用。
A late answer but may be useful to others.
下面是一个简单的Hello Web服务器,而不是你问什么,但可以继续从这里开始。下面的程序假设你有一个 WWW
目录中的SD卡的根目录和文件 index.html的
里面。
Here is a simple hello Web Server, not exactly what you ask, but you can continue from here. The following program supposes you have a www
directory in the root of the SD Card and a file index.html
inside.
主要活动 Httpd.java
:
package com.inforscience.web;
import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
import java.io.*;
import java.util.*;
public class Httpd extends Activity
{
private WebServer server;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
server = new WebServer();
try {
server.start();
} catch(IOException ioe) {
Log.w("Httpd", "The server could not start.");
}
Log.w("Httpd", "Web server initialized.");
}
// DON'T FORGET to stop the server
@Override
public void onDestroy()
{
super.onDestroy();
if (server != null)
server.stop();
}
private class WebServer extends NanoHTTPD {
public WebServer()
{
super(8080);
}
@Override
public Response serve(String uri, Method method,
Map<String, String> header,
Map<String, String> parameters,
Map<String, String> files) {
String answer = "";
try {
// Open file from SD Card
File root = Environment.getExternalStorageDirectory();
FileReader index = new FileReader(root.getAbsolutePath() +
"/www/index.html");
BufferedReader reader = new BufferedReader(index);
String line = "";
while ((line = reader.readLine()) != null) {
answer += line;
}
reader.close();
} catch(IOException ioe) {
Log.w("Httpd", ioe.toString());
}
return new NanoHTTPD.Response(answer);
}
}
}
显然, NanoHTTPD
类必须在同一个包。
Obviously the NanoHTTPD
class must be in the same package.
您需要在的AndroidManifest.xml
授予网络权限。
You need to grant internet permission in AndroidManifest.xml
.
<uses-permission android:name="android.permission.INTERNET" />
编辑::要访问服务器打开你的网页浏览器与您的设备,如的IP 192.168.1.20:8080
。
To access the server open you web browser with the IP of your device, e.g. 192.168.1.20:8080
.
注:
- 在经过测试,在安卓2.3
- 在使用80端口限制root用户(<一个href="http://www.mail-archive.com/android-developers@googlegroups.com/msg47377.html">http://www.mail-archive.com/android-developers@googlegroups.com/msg47377.html).
