CURLOPT_POSTFIELDS 编码

Question

I'm not sure about what encoding to use when using cURL:

GET:

(URL=) http://www.example.com/form.php?test=test+1

(URL=) http://www.example.com/form.php?test=test%201

POST:

(POSTFIELDS=) test=test 1

(POSTFIELDS=) test=test+1

(POSTFIELDS=) test=test%201

CURL can accept an array of arguments for post, and it'll take care of the encoding for you:

$array = (
    'test' => 'test 1',
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $array);

However, as per the curl docs (http://php.net/curl_setopt, search for CURLOPT_POST_FIELDS), for PHP, the pairs should be in urlencode() format:

$post_args = urlencode('test=test 1');
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_args);
