php http模拟POST提交上传图片

最近需要用http模拟表单提交，简单的数据提交倒是简单，如果要上传图片就要稍微做些变动了。下面分享一下，利用curl和fsockopen两种方法实现，我测试通过的例子。

发送请求的页面:fsocketupload.php

<?php
/**

header("Content-type:text/html; charset=utf-8");  //声明编码
//模拟POST上传图片和数据
//第一种方法：CURL
$ch = curl_init();
$url = "http://www.test.localhost/fsocketget.php";
$curlPost = array("sid"=>1,"file"=>"@D:/xampp/htdocs/www/www.test.localhost/images/adding.gif");
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1); //POST提交
curl_setopt($ch, CURLOPT_POSTFIELDS,$curlPost);
$data =curl_exec($ch);
curl_close($ch);
echo "<pre>";
var_dump($data);
 
//第二种方法：fsockopen方法上传
 
$arr_data = array("sid"=>1,"mid"=>2);  //普通参数
$var_file="image";       //文件变量名
$file_type="image/jpeg"; //文件类型
$filepath = "D:/xampp/htdocs/www/www.test.localhost/images/2.jpg"; //文件路径
$filestring = @file_get_contents($filepath) or exit("not found file ( ".$filepath." )"); //生成文件流
$host = "www.test.localhost";
 
 
 
//构造post请求的头
$boundary = substr(md5(time()),8,16);  //分隔符
$header  = "POST /fsocketget.php HTTP/1.1
";//一般有post, get这两种
$header .= "Host: {$host}
";
$header .= "Content-Type: multipart/form-data; boundary={$boundary}
";
 
$data = "";
//请求普通数据
foreach($arr_data as $k=>$v){
 $data .= "--{$boundary}
";
 $data .= "Content-Disposition: form-data; name="{$k}"
";
 $data .= "
{$v}
";
 $data .= "--{$boundary}
";
}
//请求图片数据
$filename = basename($filepath); //文件名
$data .= "--{$boundary}
";
$data .= "Content-Disposition: form-data; name="$var_file"; filename="$filename"
";
$data .= "Content-Type: $file_type
";  //
不可少
$data .= "
$filestring
";           //
不可少
$data .= "--{$boundary}
";             //
不可少
$header .= "Content-Length: ".strlen($data)."

";   //
不可少
 
//发送post的数据
$fp = fsockopen($host,80,$errno,$errstr,10) or exit($errstr."--->".$errno);
fputs($fp,$header.$data);
 
$inheader = 0;  //1去除请求包的头只显示页面的返回数据 0-保留头
while (!feof($fp)) {
 $line = fgets($fp,1024);
 if ($inheader && ($line == "
" || $line == "
")) {
  $inheader = 0;
 }
 if ($inheader == 0) {
  echo $line;
 }
}
 
fclose($fp);

请求api页面：fsocketget.php

<?php
/* 接收请求的API */
if($_POST){
 echo "<pre>";
 print_r($_POST);
 print_r($_FILES);
}else{
 echo "error";
}
