㈠ Mac 怎么抓取网页的视频
运行Safari,点击窗口右上角的“显示通用Safari设置菜单”图标,就是这个,把默认不显示的菜单栏调出来。
然后,在菜单栏里点击“编辑”→“偏好设置”。在弹出的窗口中,点击上方选项按钮中最右边的“高级”按钮,然后勾选最下方的“在菜单栏中显示‘开发’菜单”,就像这样
。接着直接关闭设置窗口就行了。
然后,打开你想要获得视频或音乐的网页,开始播放以后,点击菜单栏中的“开发”→“显示Web检查器”,会出现这个窗口。
点击最上方的“资源”按钮,然后在左边的边栏上方点击“大小”,然后下面的“资源”里的所有项都会按照大小排列。
你会注意到,“资源”列表最上方有一个后缀名为“flv”的文件,在它右边的图表中与它相对应的部分是一个长长的灰色长条。没错,它就是网页中的“其他”“资源”,也就是我们要找的网页视频!在左边边栏里点击这个文件,右边本来是图表的地方就会出现一个地址。复制它!开一个新标签或者新窗口,把地址贴近地址栏里,然后回车!
㈡ 如何在iOS版Safari中“查看源代码”
1、在iOS版Safari中,通过图示位置来添加书签进行存储。
㈢ safari如何查看源代码
Safari查看网页源代码的方法如下:
第一步:打开safari 的 偏好设置
㈣ IOS怎么抓取网络请求包
好吧,苹果提供了命令行监控的方法,将iPhone连接到Mac电脑的USB,输入特定命令来监听iPhone的所有网络请求。
请求的内容会写入到一个文件,读取该文件即可获取所有网络请求。
而该文件需要特定工具才能打开,用WireShark,它再次派上了用场。
——————监控网络请求的步骤—————–
1.将iPhone连接到Mac电脑
2.从Xcode或者iTunes获得iPhone的UUID,一串32位的标示,类似0B6814B3-EB2F-5B85-929D-7C5C5SS8DB64
3.命令行输入rvictl -s [你的手机UUID标示],打开Mac监听
4.命令行输入sudo tcpmp -i rv0 -n -s 0 -w mpFile.pcap tcp,开始向文件写入监控数据
结束监听时,ctrl+c关闭tcpmp进程。
关闭Mac监听,命令是 rvictl -v [你的手机UUID标示]

iOS Packet Tracing
iOS does not support packet tracing directly. However, if you’re developing for iOS you can take a packet trace of your app in a number of different ways:
If the problem you’re trying to debug occurs on Wi-Fi, you can put your iOS device on a test Wi-Fi network. See Wi-Fi Capture for details.
If your app uses HTTP, you can configure your iOS device to use a debugging HTTP proxy (such as Charles HTTP Proxy).
In iOS 5 and later you can use the remote virtual interface facility.
Remote Virtual Interface
iOS 5 added a remote virtual interface (RVI) facility that lets you use OS X packet trace programs to capture traces from an iOS device. The basic strategy is:
Connect your iOS device to your Mac via USB.
Set up an RVI for that device. This creates a virtual network interface on your Mac that represents the iOS device’s networking stack.
Run your OS X packet trace program, and point it at the RVI created in the previous step.
To set up an RVI, you should run the rvictl tool as shown below.
# First get the current list of interfaces.# First get the current list of interfaces. ifconfig -l
lo0 gif0 stf0 en0 en1 p2p0 fw0 ppp0 utun0
# Then run the tool with the UDID of the device.# Then run the tool with the UDID of the device. rvictl -s
Starting device [SUCCEEDED]
# Get the list of interfaces again, and you can see the new virtual# Get the list of interfaces again, and you can see the new virtual # network interface, rvi0, added by the previous command.
$ ifconfig -l
lo0 gif0 stf0 en0 en1 p2p0 fw0 ppp0 utun0 rvi0
Now that you know the name of the RVI, you can point your packet trace tool at it. For example, here’s how you might run tcpmp to take a packet trace from the RVI and write it to the file trace.pcap.
$ sudo tcpmp -i rvi0 -w trace.pcap
tcpmp: WARNING: rvi0: That device doesn’t support promiscuous mode
(BIOCPROMISC: Operation not supported on socket)
tcpmp: WARNING: rvi0: no IPv4 address assigned
tcpmp: verbose output suppressed, use -v or -vv for full protocol decode
listening on rvi0, link-type RAW (Raw IP), capture size 65535 bytes
When you’re done you can remove the RVI with the following command.
$ rvictl -x
Stopping device [SUCCEEDED]
Important: The RVI represents the entire networking stack of the iOS device; there’s no way to trace a specific interface on the device, or even learn which packets were transferred on which interface.
㈤ 苹果电脑怎么查看企业官网源代码
1、在打开的网页上鼠标右键——查看源代码,不限于查看自己站代码,也可以查看别人的,不过只能看不能改。2、自己的站就登陆ftp到自己站点,可以直接看到站点源文件。用文本编辑软件打开就可以查看和编辑了。
