楼主好,看到楼主的帖子也是在前不久,对于刚接触casperjs的我来说是受益匪浅,于是我也研究起casperjs来,但是今天遇到了一个问题:我在抓取一个页面的时候,页面通过js拼接成url,然后浏览器再请求这些js拼接之后的ur来动态生成内容,起初我想直接请求这些url来获取数据,后来发现这些拼接的url都带着很多的加密信息,所以对我来说,破解这些加密信息再拼接url实在是困难,于是我就利用casperjs的onResourceReceived和onResourceRequested来解惑浏览器发出去的和接收到的所有的请求地址,这样我就能直接拿到这些url,不用再拼接了。到这里似乎已经成功了,并暗自窃喜,但是后来发现,我再请求这些url的时候也不行,因为这些url应该是被设置了请求id了,每个请求过后,之后再去请求的话,会被判断为请求过期,我猜是在服务端对每个连接生成了一个请求id,请求之后将id过期,这就导致了我抓到这些url也是没用的,所以我只能寻求其他办法,我看到这些请求的content内容是我想要的,所以我就想,能不能直接拿到这些content,但是查遍了casperjs,也没找到一个样例,不知道楼主在这方面是否有经验,望指点二三。
