怎么用PHP发送HTTP请求

方法一：利用php的socket编程来直接给接口发送数据来模拟post的操作。

建立两个文件post.php,getpost.php

post.php内容如下：

?php

$flag = 0;

$post = '';

$errno = '';

$errstr = '';

//要post的数据

$argv = array(

'var1'='abc',

'var2'='how are you , my friend??');

//构造要post的字符串

foreach ($argv as $key=$value) {

if ($flag!=0) {

$post .= "";

$flag = 1;

}

$post.= $key."="; $post.= urlencode($value);

$flag = 1;

}

$length = strlen($post);

//创建socket连接

$fp = fsockopen("localhost",81,$errno,$errstr,10) or exit($errstr."---".$errno);

//构造post请求的头

$header = "POST /flandy/getpost.php HTTP/1.1\r\n";

$header .= "Host:127.0.0.1\r\n";

$header .= "Referer:/flandy/post.php\r\n";

$header .= "Content-Type: application/x-www-form-urlencoded\r\n";

$header .= "Content-Length: ".$length."\r\n";

$header .= "Connection: Close\r\n\r\n";

//添加post的字符串

$header .= $post."\r\n";

//发送post的数据

fputs($fp,$header);

$inheader = 1;

while (!feof($fp)) {

$line = fgets($fp,1024); //去除请求包的头只显示页面的返回数据

if ($inheader ($line == "\n" || $line == "\r\n")) {

$inheader = 0;

}

if ($inheader == 0) {

echo $line;

}

}

fclose($fp);

?

getpost.php的内容如下

?php

echo "this is the data posted";

echo "pre";

print_r($_REQUEST);

echo "/pre";

?

结果输出：

this is the data posted

Array

(

[var1] = abc

[var2] = how are you , my friend??

)

以上代码在本机81端口下已经通过测试。

方法二：

使用PHP的curl扩展或HttpClient.class.php类，这两个非常类似，下面简单的列出curl的实现代码。

两个文件post2.php和getpost2.php

post2.php的内容如下：

?php

$psecode = ’NDE005’;

$website = ’’;

$amt = 1;

$pwd = 123456;

$ch = curl_init();

$curl_url = "" . $website .

"pwd=" . $pwd . "action=checkpseid=" . $psecode .

"amt=" . $amt;

curl_setopt($ch, CURLOPT_URL, $curl_url);

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//不直接输出，返回到变量

$curl_result = curl_exec($ch);

$result = explode(',', $curl_result);

curl_close($ch);

print_r($result);

?

getpost2.php的内容如下：

?php

echo "returndatabr";

echo "pre";

print_r($_REQUEST);

echo "/pre";

?

结果输出：

Array ( [0] = returndataArray

(

[web] = ’wwwbaiducom’

[pwd] = 123456

[action] = check

[pseid] = ’NDE005’

[amt] = 1

)

)

phpstorm 怎么设置http代理服务器

1：点击File-Settings-Deployment 。点+按钮增加服务

2：填写Apache服务器的路径

3：现在打开通过PhpStorm打开浏览器再试试就可以了。

PHP使用代理方法获取远程网页的代码.

不要用file_get_contents函数。

用snoopy的类，网上有snoopy.class.php，你自行百度查找。

snoopy的类可以设置$proxy_host参数，设置代理主机，$proxy_port是代理主机端口。你下载一个下来，网上的教程很多，看看应该明白。

可以通过购买虚拟主机搭建自己的http代理服务器吗？

虚拟主机是无法作为VPN来使用的 建议您使用香港VPS或者云主机 ， 可以开启VPN服务。 希望可以帮到你 时代互联为您解答

使用thinkphp 怎么实现反向代理

改自PHP Reverse Proxy PRP，修改了原版中的一些错误，支持了文件上传以及上传文件类型识别，支持指定IP，自适应SAE环境。

使用方法

?123456789 ?php $proxy=new PhpReverseProxy(); $proxy-port="8080"; $proxy-host="ww"; //$proxy-ip="1.1.1.1"; $proxy-forward_path=""; $proxy-connect(); $proxy-output(); ?
