PHP cURL Post 请求无效

Question

我有问题运行正确的 cURL 请求。我打算向 URL.

发出 Post 请求

示例只运行一个命令行 cURL request

$ curl -i -X POST {URL}

我的问题是运行以下代码，我收到“400 错误请求”

$ch = curl_init();
curl_setopt( $ch, CURLOPT_POST, 1 );
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_TIMEOUT, 10 );
$output = curl_exec( $ch );
curl_close( $ch );

任何人都可以帮助正确发送请求。

Answer 1

curl_setopt( $ch, CURLOPT_POST, TRUE );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $array );

勾选manual

Answer 2

您错过了您希望通过请求获得的 CURLOPT_POSTFIELDS。正如所解释的 here 你需要设置这些字段：

<?php
//
// A very simple PHP example that sends a HTTP POST to a remote site
//

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,"http://www.example.com/tester.phtml");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
            "postvar1=value1&postvar2=value2&postvar3=value3");

// in real life you should use something like:
// curl_setopt($ch, CURLOPT_POSTFIELDS, 
//          http_build_query(array('postvar1' => 'value1')));

// receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec ($ch);

curl_close ($ch);

// further processing ....
if ($server_output == "OK") { ... } else { ... }

?>

试试这个：

POST Function:

function httpPost($url,$params)
{
  $postData = '';
   //create name value pairs seperated by &
   foreach($params as $k => $v) 
   { 
      $postData .= $k . '='.$v.'&'; 
   }
   rtrim($postData, '&');

    $ch = curl_init();  

    curl_setopt($ch,CURLOPT_URL,$url);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
    curl_setopt($ch,CURLOPT_HEADER, false); 
    curl_setopt($ch, CURLOPT_POST, count($postData));
        curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);    

    $output=curl_exec($ch);

    curl_close($ch);
    return $output;

}

Calling the Function:

$params = array(
   "name" => "Ravishanker Kusuma",
   "age" => "32",
   "location" => "India"
);

echo httpPost("http://hayageek.com/examples/php/curl-examples/post.php",$params);

看看有没有帮助。参考：link

Answer 4

至post，只需使用以下curl选项并尝试。

(if your url is - "https") {
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); //if required.
curl_setopt($ch, CURLOPT_URL, );
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
return curl_exec($ch);

我想您传递的 url 没有 post 字段。您可以使用 CURLOPT_POSTFIELDS 和您的 post 参数，或者使用 http_build_query(post 参数将其附加到 url http://www.url.com?arg1=val1&arg2=val2

Answer 5

同样的代码花了 5 个小时后，我才找到了我的问题的解决方案

如果您在 post 字段中使用数组，您必须 json_encode 该数组才能识别为 POST 参数

        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
        curl_setopt($curl, CURLOPT_POST, true);
        curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($fields));
        curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
       $data = curl_exec($curl);

所以这是使用 POST 请求的 CURL 代码给代表+如果我的
