PHP使用CURL模拟POST/GET/PUT/DELETE方式提交数据

$content = file_get_contents("http://www.doucube.com");
  // or
  $lines = file("http://www.doucube.com");
  // or
  readfile(http://www.doucube.com);

   不过，这种做法缺乏灵活性和有效的错误处理。而且，你也不能用它完成一些高难度任务——比如处理coockies、验证、表单提交、文件上传等等。所以选择curl库。

示例代码：

<?php
    $url = 'https://www.google.com';
    $method = 'POST';
     
    //headers and data (this is API dependent, some uses XML)：
    //即在接口调用时才用headers 和$data
    $headers = array(
    'Accept: application/json',
    'Content-Type: application/json',
    );
    $data = json_encode(array(
    'firstName'=> 'John',
    'lastName'=> 'Doe'
    ));

    // 启动一个CURL会话
    $handle = curl_init();
    curl_setopt($handle, CURLOPT_URL, $url); // 要访问的地址
    curl_setopt($handle,CURLOPT_HEADER,1); // 是否显示返回的Header区域内容
    curl_setopt($handle, CURLOPT_HTTPHEADER, $headers); //设置请求头
    curl_setopt($handle, CURLOPT_RETURNTRANSFER, true); // 获取的信息以文件流的形式返回
    curl_setopt($handle, CURLOPT_SSL_VERIFYHOST, false); // 从证书中检查SSL加密算法是否存在
    curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false); // 对认证证书来源的检查
     
    switch($method) {
    case 'GET':
    break;
    case 'POST':
    curl_setopt($handle, CURLOPT_POST, true);
    curl_setopt($handle, CURLOPT_POSTFIELDS, $data); //设置请求体，提交数据包
    break;
    case 'PUT':
    curl_setopt($handle, CURLOPT_CUSTOMREQUEST, 'PUT');
    curl_setopt($handle, CURLOPT_POSTFIELDS, $data); //设置请求体，提交数据包
    break;
    case 'DELETE':
    curl_setopt($handle, CURLOPT_CUSTOMREQUEST, 'DELETE');
    break;
    }
     
    $response = curl_exec($handle); // 执行操作
    $code = curl_getinfo($handle, CURLINFO_HTTP_CODE); // 获取返回的状态码
    curl_close ($handle); // 关闭CURL会话
    if('200'==$code){
      echo "ok";
    }
    

    下面还有一个示例，有兴趣可以看看：

用curl上传文件的话很方便，什么header,post串都不用生成了,用fsockopen要写一堆 curl: ==============

PHP code

$file = array("upimg"=>"@E:/png.png");//文件路径，前面要加@，表明是文件上传.

$curl = curl_init("http://localhost/a.php");

curl_setopt($curl,CURLOPT_POST,true);

curl_setopt($curl,CURLOPT_POSTFIELDS,$file);

curl_exec($curl);

 

 

fsockopen: ===============

PHP code $uploadFile = file_get_contents("E:/png.png"); $boundary   = md5(time());

$postStr .="--".$boundary."
";//边界开始,注意默认比header定义的boundary多两个'-'

$postStr .="Content-Disposition: form-data; name="upimg"; filename="E:/png.png"
";

$postStr .="Content-Type: image/png

";

$postStr .=$uploadFile."
"; $postStr .="--".$boundary."
";//边界结束

write($fp,"POST /a.php HTTP/1.0
");

fwrite($fp,"Content-Type: multipart/form-data; boundary=".$boundary."
");

fwrite($fp,"Content-length:".strlen($postStr)."

");

fwrite($fp,$postStr);

while (!feof($fp))

{     

echo fgets($fp, 128);

}

fclose($fp);

 

 

a.php ==============

PHP code print_r($_FILES);
