使用PHP cURL发布JSON并显示JSON响应

php json curl

使用PHP cURL发布JSON并显示JSON响应,php,json,curl,Php,Json,Curl,为了找到我的问题的答案，我在堆栈溢出问题上做了很多研究，但就是找不到答案。我试图发布以下JSON <?php $data_string = '{ "jsonrpc": "2.0", "method": "login", "id": 1, "params": { "params": { "username": "4321", "password": "123

为了找到我的问题的答案，我在堆栈溢出问题上做了很多研究，但就是找不到答案。我试图发布以下JSON

<?php

$data_string = '{
        "jsonrpc": "2.0",
        "method": "login",
        "id": 1,
        "params": {

            "password":  "1234"
          }
        }
      }';

$ch = curl_init('https://domain.com');

$result = curl_exec($ch);

echo $result;

我没有得到任何回应，即使它可以与jQuery和AJAX配合使用。当我检查Chrome的开发者工具时，方法是GET，当我将它设置为POST时，这很奇怪

知道我做错了什么吗？

CURLOPT_POSTFIELDS:一定是这样a=1111&b=2222

example 1:
<?php
$useragent = 'PHP Client 1.0 (curl) ' . phpversion();
$post_string="a=1&b=1";
$url_with_get="http://xxx.xxx.com";
$result = @exec("curl -s --connect-timeout 10 --user-agent \"$useragent\" -d\"$post_string\" \"$url_with_get\"");
var_dump($result);
?>

example 2:
<?php
$useragent = 'PHP Client 1.0 (curl) ' . phpversion();
$post_string="a=1&b=1";
$url_with_get="http://xxx.xxx.com";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url_with_get);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$result = curl_exec($ch);
curl_close($ch);

var_dump($result);
?>

example 3:
<?php
$content_type = 'application/x-www-form-urlencoded';
$content = "a=1&b=1";
$server_addr = "http://xxx.xxx.com";
var_dump(http_post($content_type, $content, $server_addr));

function http_post($content_type, $content, $server_addr) {

                $user_agent = 'PHP Client 1.0 (non-curl) ' . phpversion();

尝试使用JSON字符串作为请求正文发出GET请求：

你能看到你的args在接收端的样子吗

新秀们的回答是：这可能与你如何通过季后赛有关吗？通常，postfield参数需要键值数组或urlencoded字符串key1=val1&。如果没有JSON$data_字符串值的键，服务器是否知道如何接受postfields？你可以试试下面的吗

// Personal preference here - arrays are easier for me to read
// Create a multi dem array dictionary with your values
$_dictionary = array("jsonrpc"=>"2.0",
                     "method" =>"login",
                     "id"     =>1,
                     "params" =>array("params"=>array("username"=>"4321","password"=>"1234"))
                    );

// json_encode 
$_dictionary = json_encode($_dictionary);

// your $data_string variable will now be in key=value  
$data_string = "mydata={$_dictionary}";

// set $data_string to your CURLOPT_POSTFIELDS...

我知道这个问题已经提了2年了，但它仍然得到了很多意见

这看起来像是SSL问题。你可以试试：

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

有关更多信息，请阅读以下内容：

我不确定它是否能与GET一起使用，因为我需要发布$data\u字符串，然后从服务器检索JSON响应。还是我错了？这取决于服务器端。您说过，当您使用AJAX发出GET请求时，它对您有效。我不确定它是否适用于GET，因为我需要发布$data\u字符串，然后从服务器检索JSON响应。还是我错了？这取决于服务器端。您说过，当您使用AJAX发出GET请求时，它对您有效。
