使用 php curl 自动填充文本区域

发布于 2024-08-10 18:34:38 字数 329 浏览 5 评论 0原文

我们正在尝试自动填充具有文本区域的表单。

<textarea name="myarea"></textarea>

我们可以使用curl 来做到这一点，但是它只接受输入文本的一部分。如果内容太大，则不接受任何内容。文本区域的字符数没有限制。

$area['myarea']=>"a large html code.................."
curl_setopt($ch,CURL_POSTFIELDS,$area);
curl_execute();

请提出解决方案。

原文

We are trying to auto populate a form which is having a text area.

<textarea name="myarea"></textarea>

We can do it using curl however it is accepting only the part of the input text. If the content is too large then it accepts nothing. There is no restriction with respect to number of characters on the text area.

$area['myarea']=>"a large html code.................."
curl_setopt($ch,CURL_POSTFIELDS,$area);
curl_execute();

Please suggest the solution.

您确定您正确转义了参数吗？只需使用 urlencode() 即可达到此目的。这是一个例子：

<?php
$url = 'http://localhost/';

$fields = array (
  'param1' => 'val1',
  'param2' => 'val2'
);

$qry = '';
foreach ($fields as $key => $value) {
  $qry .= $key . '=' . urlencode($value) . '&';
}
$qry = rtrim($qry, '&');

// Alternatively, you can also use $qry = http_build_query($fields, '');

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $qry);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($ch);

curl_close($ch);

var_dump($result);
?>

如果你想验证请求是否正确发送，我会推荐netcat。只需将 URL 设置为 http://localhost:3333/ ，然后使用以下命令执行 netcat：
$ nc -l -p 3333

正如预期的那样，请求如下所示：
发布/HTTP/1.1
主机：本地主机：3333
接受：/
内容长度：23
内容类型：application/x-www-form-urlencoded

param1=val1¶m2=val2

Are you sure you escaped the parameter correctly? Just use urlencode() for this purpose. Here is an example:

<?php
$url = 'http://localhost/';

$fields = array (
  'param1' => 'val1',
  'param2' => 'val2'
);

$qry = '';
foreach ($fields as $key => $value) {
  $qry .= $key . '=' . urlencode($value) . '&';
}
$qry = rtrim($qry, '&');

// Alternatively, you can also use $qry = http_build_query($fields, '');

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $qry);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($ch);

curl_close($ch);

var_dump($result);
?>

If you want to verify that the request was send properly, I would recommend netcat. Just set the URL to http://localhost:3333/ and then execute netcat using:
$ nc -l -p 3333

As expected, the request looks like this:
POST / HTTP/1.1
Host: localhost:3333
Accept: /
Content-Length: 23
Content-Type: application/x-www-form-urlencoded
