由于Cloudflare无法从网址读取数据 [英] Can't read data from url due to cloudflare

问题描述

每次编译时，我都会得到：

Whenever I compile, i get this:

线程 main中的异常java.io.IOException：服务器返回了HTTP
响应代码：URL的403：位于
sun.net.www.protocol.http.HttpURLConnection.getInputStream0（未知
源）处的链接，位于
sun.net.www.protocol。位于java.net的http.HttpURLConnection.getInputStream（未知
源）位于
的URL.openStream（未知源）readdata.aaa.main（aaa.java:15）

Exception in thread "main" java.io.IOException: Server returned HTTP response code: 403 for URL: the link at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.net.URL.openStream(Unknown Source) at readdata.aaa.main(aaa.java:15)

我的脚本是：

package readdata;

import java.net.*;
import java.io.*;
import java.util.regex.Pattern;
import java.util.regex.Matcher;

public class aaa 
{
    public static void main(String[] args) throws Exception {

        URL oracle = new URL(" the link ");
        BufferedReader in = new BufferedReader(
        new InputStreamReader(oracle.openStream()));

        String inputLine;
        StringBuilder a = new StringBuilder();
        while ((inputLine = in.readLine()) != null)
            a.append(inputLine);
        in.close();


        int i = 0;
        Pattern p = Pattern.compile("Open");
        Matcher m = p.matcher( a );
        while (m.find()) {
            i++;
            System.out.println(i);
        }
    }

}

无论如何，我可以绕过cloudflare以便从URL读取数据？

Is there anyway I can bypass the cloudflare in order to read the data from the URL ?

推荐答案

之前

URL oracle = new URL(" the link ");

插入：

System.setProperty("http.agent", "Chrome");

这可能是因为CloudFlare阻止了未知的代理请求，因此此代码将User-Agent设置为Chrome被CloudFlare认可。

That's probably because CloudFlare prevent from unknown agent requests so this code set the User-Agent to Chrome who is recognized by CloudFlare.
