复制网页 停用java的实现流程如下:
graph TD
A[开始]-->B[下载网页源文件]
B-->C[停用Java]
C-->D[保存停用Java后的网页]
D-->E[结束]
具体步骤及代码如下:
- 下载网页源文件:首先需要从指定的URL下载网页的源文件,可以使用Java中的URLConnection类实现。代码如下:
import java.io.BufferedInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
import java.net.URLConnection;
public class DownloadWebpage {
public static void main(String[] args) {
String urlString = "网页URL";
String filename = "保存的文件名";
try {
URL url = new URL(urlString);
URLConnection connection = url.openConnection();
InputStream inputStream = connection.getInputStream();
BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream);
FileOutputStream fileOutputStream = new FileOutputStream(filename);
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = bufferedInputStream.read(buffer, 0, 1024)) != -1) {
fileOutputStream.write(buffer, 0, bytesRead);
}
fileOutputStream.close();
bufferedInputStream.close();
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
- 停用Java:通过分析网页的源文件,找到所有的Java代码部分,并将其注释掉或删除,可以使用字符串处理方法实现。代码如下:
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
public class DisableJava {
public static void main(String[] args) {
String filename = "下载的网页文件";
String disabledFilename = "停用Java后的网页文件";
try {
FileReader fileReader = new FileReader(filename);
BufferedReader bufferedReader = new BufferedReader(fileReader);
FileWriter fileWriter = new FileWriter(disabledFilename);
String line;
while ((line = bufferedReader.readLine()) != null) {
if (!line.contains("<script language=\"java\">") && !line.contains("<script language='java'>")) {
fileWriter.write(line);
fileWriter.write("\n");
}
}
fileWriter.close();
bufferedReader.close();
fileReader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
- 保存停用Java后的网页:将停用Java后的网页内容保存到指定的文件中,可以使用Java的文件写入操作实现。代码如下:
import java.io.FileWriter;
import java.io.IOException;
public class SaveDisabledWebpage {
public static void main(String[] args) {
String disabledFilename = "停用Java后的网页文件";
String savedFilename = "保存的网页文件";
try {
FileReader fileReader = new FileReader(disabledFilename);
BufferedReader bufferedReader = new BufferedReader(fileReader);
FileWriter fileWriter = new FileWriter(savedFilename);
String line;
while ((line = bufferedReader.readLine()) != null) {
fileWriter.write(line);
fileWriter.write("\n");
}
fileWriter.close();
bufferedReader.close();
fileReader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
以上是实现复制网页并停用Java的流程,代码中的注释已经解释了每一行代码的作用。通过按照以上步骤和代码的操作,即可实现复制网页并停用Java的功能。
