無(wú)狀態(tài)：每次請(qǐng)求完成就結(jié)束連接，下一次請(qǐng)求與上次請(qǐng)求沒(méi)有關(guān)系。

報(bào)文：HTTP交互的信息。

telnet模擬請(qǐng)求： // GET方式，最后回車(chē)換行

Aston$ telnet 127.0.0.1 80

GET /Tools/Test/http.php HTTP/1.1

Host:localhost

// POST方式，最后回車(chē)換行,輸入?yún)?shù)

Aston$ telnet 127.0.0.1 80

POST /Tools/Test/http.php HTTP/1.1

Host:localhost

Content-type:application/x-www-form-urlencoded

Content-length:20

name=chenjian&age=28

fiddler用法：

利用file_get_content來(lái)發(fā)送數(shù)據(jù)： $data = array(

'name' => 'chenjian',

'age' => 28

);

$postData = http_build_query($data);

$opts = array(

'http' => array(

'host' => "localhost\r\n",

'method' => "POST",

'header' => "Content-type:application/x-www-form-urlencoded\r\n" . "Content-length:".strlen($postData)."\r\n",

'content' => $postData

);

);

$context = stream_context_create($opts);

file_get_contents("http://localhost/http/index.php", false, $context);

socket方式： $data = array(

'name' => 'chenjian',

'age' => 28

);

$postData = http_build_query($data);

$fp = fsockopen("localhost", 80, $errno, $errorStr, 5);

$request = "POST http://localhost/http/socket.php HTTP/1.1\r\n";

$request .= "Host:locahost\r\n";

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

$request .= "Content-length:" . strlen($postData) . "\r\n";

$request .= $postData;

fwrite($fp, $request);

while (!feof($fp)) {

echo fgets($fp, 1024);

}

fclose($fp);

curl拓展： $url = "http://localhost/http/curl.php";

$data = array(

'name' => 'chenjian',

'age' => 28

);

// 1. 初始化curl會(huì)話

$ch = curl_init();

// 2. 設(shè)置

curl_setopt($ch, CURLOPT_URL, $url); //提交網(wǎng)址

curl_setopt($ch, CURLOPT_POST, 1); //提交方式

curl_setopt($ch, CURLOPT_POSTFIELDS, $data); //提交數(shù)據(jù)

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //提交成功后返回?cái)?shù)據(jù)字符串

// 3. 執(zhí)行

$out_put = curl_exec($ch);

// 4. 關(guān)閉會(huì)話

curl_close($ch);

var_dump($out_put);
