Curl和PHP - 如何通过PUT，POST，GET将json传递给curl

问题描述：

I have been working on building an Rest API for the hell of it and I have been testing it out as I go along by using curl from the command line which is very easy for CRUD

I can successfully make these call from the command line

curl -u username:pass -X GET http://api.mysite.com/pet/1
curl -d '{"dog":"tall"}' -u username:pass -X GET http://api.mysite.com/pet
curl -d '{"dog":"short"}' -u username:pass -X POST http://api.mysite.com/pet
curl -d '{"dog":"tall"}' -u username:pass -X PUT http://api.mysite.com/pet/1

The above calls are easy to make from the command line and work fine with my api, but now I want to use PHP to create the curl. As you can see, I pass data as a json string. I have read around and I think I can probably do the POST and include the POST fields, but I have not been able to find out how to pass http body data with GET. Everything I see says you must attached it to the url, but it doesn't look that way on the command line form. Any way, I would love it if someone could write the correct way to do these four operations in PHP here on one page. I would like to see the simplest way to do it with curl and php. I think I need to pass everything through the http body because my php api catching everything with php://input

我一直在努力为它构建一个Rest API，我一直在测试它从命令行使用curl这对CRUD非常容易 p>

我可以从命令行成功进行这些调用 p>

  curl  -u username：pass -X GET http://api.mysite.com/pet/1
curl -d'{“dog”：“tall”}' -  u username：pass -X GET http：// api。  mysite.com/pet
curl -d'{“dog”：“short”}' - 用户名：pass -X POST http://api.mysite.com/pet
curl -d'{“dog”：“  tall“}' - 用户名：pass -X PUT http://api.mysite.com/pet/1

上述电话很容易从命令行和我的api工作正常，但现在我想用PHP来创建curl。如您所见，我将数据作为json字符串传递。我已经阅读过，我认为我可以做POST并包含POST字段，但我无法找到如何通过GET传递http正文数据。我看到的一切都说你必须将它附加到网址上，但它在命令行表单上看起来并不那样。无论如何，如果有人能在一页上用PHP编写正确的方法来完成这四项操作，我会很高兴。我想看看用curl和php做最简单的方法。我想我需要通过http主体传递所有内容，因为我的php api用php：// input p> div>捕获所有内容

PUT

$data = array('username'=>'dog','password'=>'tall');
$data_json = json_encode($data);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Content-Length: ' . strlen($data_json)));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response  = curl_exec($ch);
curl_close($ch);

POST

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response  = curl_exec($ch);
curl_close($ch);

GET See @Dan H answer

DELETE

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response  = curl_exec($ch);
curl_close($ch);

For myself, I just encode it in the url and use $_GET on the destination page. Here's a line as an example.

$ch = curl_init();
$this->json->p->method = "whatever";
curl_setopt($ch, CURLOPT_URL, "http://" . $_SERVER['SERVER_NAME'] . $this->json->path . '?json=' . urlencode(json_encode($this->json->p)));
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);

EDIT: Adding the destination snippet... (EDIT 2 added more above at OPs request)

<?php
if(!isset($_GET['json']))
    die("FAILURE");
$json = json_decode($_GET['json']);
$method = $json->method;
...
?>

You can use this small library: https://github.com/jmoraleda/php-rest-curl

Making a call is as simple as:

// GET
$result = RestCurl::get($URL, array('id' => 12345678));

// POST
$result = RestCurl::post($URL, array('name' => 'John'));

// PUT
$result = RestCurl::put($URL, array('$set' => array('lastName' => "Smith")));

// DELETE
$result = RestCurl::delete($URL);

And for the $result variable:

$result['status'] is the HTTP response code
$result['data'] an array with the JSON response parsed
$result['header'] a string with the response headers

Hope it helps

set one more property curl_setopt($ch, CURLOPT_SSL_VERIFYPEER , false);

I was Working with Elastic SQL plugin. Query is done with GET method using cURL as below:

curl -XGET http://localhost:9200/_sql/_explain -H 'Content-Type: application/json' \
-d 'SELECT city.keyword as city FROM routes group by city.keyword order by city'

I exposed a custom port at public server, doing a reverse proxy with Basic Auth set.

This code, works fine plus Basic Auth Header:

$host = 'http://myhost.com:9200';
$uri = "/_sql/_explain";
$auth = "john:doe";
$data = "SELECT city.keyword as city FROM routes group by city.keyword order by city";

function restCurl($host, $uri, $data = null, $auth = null, $method = 'DELETE'){
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $host.$uri);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    if ($method == 'POST')
        curl_setopt($ch, CURLOPT_POST, 1);
    if ($auth)
        curl_setopt($ch, CURLOPT_USERPWD, $auth);
    if (strlen($data) > 0)
        curl_setopt($ch, CURLOPT_POSTFIELDS,$data);

    $resp  = curl_exec($ch);
    if(!$resp){
        $resp = (json_encode(array(array("error" => curl_error($ch), "code" => curl_errno($ch)))));
    }   
    curl_close($ch);
    return $resp;
}

$resp = restCurl($host, $uri); //DELETE
$resp = restCurl($host, $uri, $data, $auth, 'GET'); //GET
$resp = restCurl($host, $uri, $data, $auth, 'POST'); //POST
$resp = restCurl($host, $uri, $data, $auth, 'PUT'); //PUT
