我有需要抓取的链接。
如何将这些链接地址作为变量添加到已删除的数据中,或者只是追加?
public void Correct() throws InterruptedException {
// Correct checking of the wait condition. The condition is checked
// before waiting inside the locked region, and is rechecked after wait
// returns.
synchronized(lock) {
while(!someCondition) {
lock.wait();
}
}
}
}
我得到的数据(例如)
links
for (i in links)
{
url<- (i)
SC <- read_html(url) %>% html_nodes ("NODES") %>% html_text ()
Data<-rbind(SC)
}
如何将第4个属性添加为链接网址
1. "name"
2. "price"
3. "date"
还是在另一栏? 谢谢
