Question

我正在尝试使用以下代码获取HTML页面的内容：

String malSearch = "http://myanimelist.net/anime.php?letter=" + firstLetter;
URL url = new URL(malSearch);
URLConnection con = url.openConnection();
InputStream in = con.getInputStream();
String encoding = con.getContentEncoding();
encoding = encoding == null ? "UTF-8" : encoding;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
byte[] buf = new byte[8192];
int len = 0;
while ((len = in.read(buf)) != -1) {
    baos.write(buf, 0, len);
}
String body = new String(baos.toByteArray(), encoding);

它工作正常，但它并没有给我我真正想要的东西。它给了我这个：

<html>
 <head>
  <META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">
  <meta name="format-detection" content="telephone=no">
  <meta name="viewport" content="initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
 </head>
 <body style="margin:0px">

Incapsula incident ID: 124001330081285077-564449081699338326</iframe>
 </body>
</html>

什么时候应该给我整页（约800行）。

我认为这是因为这是一个使用PHP的网站，但我并不确定。有人能告诉我如何获得整个HTML内容吗？

以下是我尝试从以下网址获取内容的页面：http://myanimelist.net/anime.php?letter=A

Answer 1

此网站使用名为Incapsula的服务。网站管理员配置了Incapsula以防止机器人访问它的内容。

我建议您联系管理员并要求列入白名单，试图绕过系统可能会让你被禁止并列入黑名单。

Answer 2

这是因为您从服务器返回的HTML包含应该加载的其他页面的地址。如果您希望页面显示在Web浏览器中，您的客户端应该获取其他页面并检索它们。

网站的使用情况没有区别。

编辑：仔细阅读错误消息，您会发现此错误：

Request unsuccessful. Incapsula incident ID: 124001330081285077-

您的通话出现问题，或者服务器可能不喜欢您的座席（预计会有像IE或Chrome这样的浏览器）

是的，你的电话有问题。我能够调用页面并得到没有错误的响应：

该页面上的主要内容已加载到<iframe>标记中。在该标记中，您可以看到内容网址。

String malSearch = "http://myanimelist.net//_Incapsula_Resource?CWUDNSAI=9&xinfo=6-122029399-0 0NNN RT(1404149034204 2) q(0 -1 -1 -1) r(0 -1) B12(4,315,0) U1&incident_id=124001330081285077-564449081699338326&edet=12&cinfo=4ee46646c753833e04000000";
URL url = new URL(malSearch);
URLConnection con = url.openConnection();
InputStream in = con.getInputStream();
