curl 构造 模拟 post请求

test1.php

$url = "http://localhost/uctest2.php";
$data = array (
"key1" => "value1",
"key2" => "value2",
"key3" => "value3"
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);// data是数组格式
$output = curl_exec($ch);
if ($output === false)
{
echo 'Curl error: ' . curl_error($ch);
} else {
$info = curl_getinfo($ch);
echo 'Took ' . $info['total_time'] . ';seconds to send a request to ' . $info['url'];
echo '操作完成没有任何错误';
}
curl_close($ch);
var_dump($output);
exit;

$url = "http://localhost/uctest2.php";
$post_data = array (
"key1" => "value1",
"key2" => "value2",
"key3" => "value3"
);
$data = trim(json_encode($post_data));
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);// data 是json格式
$output = curl_exec($ch);
if ($output === false)
{
echo 'Curl error: ' . curl_error($ch);
} else {

test2.php

<?php
var_dump($_POST); // data 是数组和字符串格式
?>

// 接收json 数据的方式

<?php
// 模拟非post、get以外的传输方式
$myFile = "result.log";
$fh = fopen($myFile, 'a') or die("can't open file");
$stringData = date("Y-m-d H:i:s")."\n";
fwrite($fh, $stringData);
$stringData = file_get_contents('php://input');
fwrite($fh, $stringData);
fclose($fh);
?>

CURLOPT_POSTFIELDS全部数据使用HTTP协议中的"POST"操作来发送。要发送文件，在文件名前面加上@前缀并使用完整路径。这个参数可以通过urlencoded后的字符串类似'para1=val1¶2=val2&...'或使用一个以字段名为键值，字段数据为值的数组。如果value是一个数组，Content-Type头将会被设置成multipart/form-data。
