尝试模拟请求时获取cloudflare 429，使用fiddler时未获取

Question

我试着用java模拟一个请求，但每次我尝试发送它时，我得到了一个cloudflare 429，当使用fiddler模拟同样的请求时，我得到了200个。Java代码(不工作)：

Jsoup.connect("")
            .userAgent("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.116 Safari/537.36")
            .header("Connection", "keep-alive")
            .header("Cache-Control", "max-age=0")
            .header("Upgrade-Insecure-Requests", "1")
            .header("Sec-Fetch-Dest", "document")
            .header("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9")
            .header("Sec-Fetch-Site", "none")
            .header("Sec-Fetch-Mode", "navigate")
            .header("Sec-Fetch-User", "?1")
            .header("Accept-Encoding","gzip, deflate, br")
            .header("Accept-Language","en-US,en;q=0.9,he-IL;q=0.8,he;q=0.7")
            .ignoreContentType(true)
            .ignoreHttpErrors(true)
            .method(Method.GET)
            .execute();

Fiddler RAW (工作中，200)

GET 
Connection: keep-alive
Cache-Control: max-age=0
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.116 Safari/537.36
Sec-Fetch-Dest: document
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9
Sec-Fetch-Site: none
Sec-Fetch-Mode: navigate
Sec-Fetch-User: ?1
Accept-Encoding: gzip, deflate, br
Accept-Language: en-US,en;q=0.9,he-IL;q=0.8,he;q=0.7

从字面上看，使用相同的头文件，cloudflare有没有其他方式知道我没有使用Webdriver？

您的问题不在代码级。HTTP status code 429的意思是Too many requests。

似乎你发送了太多的请求，从而触发了Cloudflare的DOS攻击防护。
