HTTP請(qǐng)求模擬工具這個(gè)的實(shí)現(xiàn)代碼用了很多Httpclent

URL?link?=?new?URL("http://www.sojson.com"); InputStream?is?=?link.openStream();直接獲取流了，優(yōu)點(diǎn)是這個(gè)簡(jiǎn)單，缺點(diǎn)是太單一了，比如不能以Post，或者帶一些頭信息什么的！

這個(gè)方法的源碼就是對(duì)HttpUrlConnection方法進(jìn)行了封裝。
public final InputStream openStream() throws IOException {
? ?return openConnection().getInputStream();
}
