PHP如何使用CURL

Question

I need to do this command

root@debian:~# curl -X PUT -d '{ "date": "2.5.", "order": 2, "prize": 45 }' '[URL]'

in PHP (or Python). But I have no idea how to do it. I tried this:

$data = '{ "date": "2.5.", "order": 2, "prize": 45 }';
$data = json_encode($data);
echo $data;
$ch = curl_init([URL]);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_PUT, true);
curl_setopt($ch, CURLOPT_POSTFIELDS,http_build_query($data));
$response = curl_exec($ch);
curl_close($ch);
echo $response;

But this returns:

{ "error" : "Error: No data supplied." }

Any idea how to reproduce it in PHP/Python?

Answer 1

$url = "[URL]";

$data = array(
"date" => "2.5.",
"order" => "2",
"prize" => 45
);

$json_data = json_encode($data);

$ch = curl_init($url);

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$content = curl_exec($ch);

curl_close($ch);

subprocess.call or subprocess.run will do what you need for this, although the output will get dumped to stdout, so you'll also need to redirect it if you want to manipulate the returned data. However, you could also use requests , like some other commenters have suggested.

https://docs.python.org/3.5/library/subprocess.html

import subprocess
import tempfile

with tempfile.TemporaryFile() as tmp:
    subprocess.call(["curl", "-X", "PUT", "-d", '{ "date": "2.5.", "order": 2, "prize": 45 }', '[URL]'], stdout=tmp)
    tmp.seek(0)
    data = tmp.read()

Accoridng to the PHP docs,

http://php.net/manual/en/function.http-build-query.php

http_build_query accepts an array or object as the paramater. Also, json_encode returns a string:

http://php.net/manual/en/function.json-encode.php

So, you need to change the way you are using them.

Further, using http_build_query might be preferable since it url-encodes the given params:

When POSTing an associative array with cURL, do I need to urlencode the contents first?

So you need to pass an array to the http_build_query function to make it work:

Example (from above link):

  $curl_parameters = array(
    'param1' => $param1,
    'param2' => $param2
  );

  $curl_options = array(
    CURLOPT_URL => "http://localhost/service",
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => http_build_query( $curl_parameters ),
    CURLOPT_HTTP_VERSION => 1.0,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HEADER => false
  );

  $curl = curl_init();
  curl_setopt_array( $curl, $curl_options );
  $result = curl_exec( $curl );

  curl_close( $curl );
