某些网站通过http header信息限制下载文件，在linux下面可以使用wget来模拟realplay等的，http header信息。wget –head “ClientID: WinNT_5.0_6.0.12.1056_play32_R30CND_zh-CN_686_axembed” –head “User-Agent: RMA/1.0 (compatible; RealMedia)” 说明：每一个header信息项用一个 –head参数来指定，，可以多次使用 –head参数。下面是我的获得的header的信息：Array([User-Agent] => RMA/1.0 (compatible; RealMedia)[Accept] => */*[Host] => localhost[Connection] => Keep-Alive[ClientID] => WinNT_5.0_6.0.12.1056_play32_R30CND_zh-CN_686_axembed)以下是下载成功和不成功的http链接信息记录：> >从IE点播的http请求，播放成功。(VOD1.cap)> >> >GET /vod2/%5bTV%5dFZXF/01.rmvb HTTP/1.1> >> >Accept: */*> >> >User-Agent: RMA/1.0 (compatible; RealMedia)> >> >Icy-MetaData: 1> >> >Bandwidth: 10485800> >> >ClientID: WinNT_5.0_6.0.12.1056_play32_R30CND_zh-CN_686_axembed> >> >GUID: 00000000-0000-0000-0000-000000000000> >> >Language: zh-CN, zh, *> >> >RegionData: 0> >> >SupportsMaximumASMBandwidth: 1> >> >Connection: Keep-Alive> >> >Host: 10.146.189.104> >> >Accept-Language: zh-CN, zh, *> >> >Accept-Encoding: gzip> >> >===================================================================> >从realplayer直接打开对应文件播放成功。(vod2.cap)> >> >GET /vod2/%5bTV%5dFZXF/01.rmvb HTTP/1.1> >> >Accept: */*> >> >User-Agent: RMA/1.0 (compatible; RealMedia)> >> >Icy-MetaData: 1> >> >Bandwidth: 10485800> >> >ClientID: WinNT_5.0_6.0.12.1056_RealPlayer_R30CND_zh-CN_686> >> >GUID: 00000000-0000-0000-0000-000000000000> >> >Language: zh-CN, zh, *> >> >RegionData: 0> >> >SupportsMaximumASMBandwidth: 1> >> >Connection: Keep-Alive> >> >Host: 10.146.189.104> >> >Accept-Language: zh-CN, zh, *> >> >Accept-Encoding: gzip> >> >> >===================================================================
