Socket Programming Post bulk posting ___ programming

First of all, this article uses a previous message board case to test, case connection: Use post to realize the message board message. The previous section is an explanation of the principle of the steps, and the second half is the code implementation that continues with the previous article. So here we go:

1. The message page is as follows:

First submit a message, then grab the packet to view the post data.

See this sentence:

<span style= "FONT-FAMILY:KAITI_GB2312;FONT-SIZE:14PX;" >title=vEagleFly&author=vEagleFly&content=vEagleFly</span>

This is the data we submitted.

So, we're going to start imitating the implementation. In fact, we have encountered here before, is this article, HTTP application of simulated irrigation robot, the truth is the same. It's just that we change the way that the class implements it.

Check the message to achieve success.

 $post->post (' title ' => ' Ceshi ', ' author ' => ' veaglefly ', ' content ' => ' no ')); </span>

"Run Results":

At this point, using socket programming to implement get and post send request data has been fully implemented.

"Knowledge development":

To achieve bulk posting (ie irrigation), add a For loop.

<span style= "FONT-FAMILY:KAITI_GB2312;FONT-SIZE:14PX;" >set_time_limit (0);
$url = ' http://127.0.0.1/liuyan/doAdd.php ';
for ($i = 0; $i <10; $i + +) {
   $post = new Http ($url);
   $post->post (' title ' => ' Guanshui ', ' author ' => ' veaglefly ', ' content ' => ' haha '));
   Usleep (20000)//delay 2s send, too fast own machine can not afford.
