curl 相关问题

我在 Stack Overflow 上查了很多资料，想找到问题的答案，但就是找不到。我正在尝试发布以下 JSON 我在 Stack Overflow 上查了很多资料，试图找到问题的答案，但就是找不到。我正在尝试发布以下 JSON <?php $data_string = '{ "jsonrpc": "2.0", "method": "login", "id": 1, "params": { "params": { "username": "4321", "password": "1234" } } }'; $ch = curl_init('https://domain.com'); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Content-Type: application/json', 'Content-Length: ' . strlen($data_string)) ); $result = curl_exec($ch); echo $result; ?> 我没有得到任何回应，尽管它与 jQuery 和 AJAX 配合得很好。我查看Chrome的开发者工具，方法是GET，这很奇怪，因为我在代码中将其设置为POST。有什么想法我做错了吗？尝试使用 JSON 字符串作为请求正文发出 GET 请求： $data_string = '{ "jsonrpc": "2.0", "method": "login", "id": 1, "params": { "params": { "username": "4321", "password": "1234" } } }'; $ch = curl_init('https://domain.com'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Content-Type: application/json', 'Content-Length: ' . strlen($data_string)) ); curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string ); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET'); $result = curl_exec($ch); echo $result; 你能看到你的参数在接收端是什么样子吗？就新秀的回答而言——这可能与你通过后场的方式有关吗？通常，postfield 参数需要键值数组或 urlencoded 字符串 (key1=val1&)。如果没有 JSON ($data_string)“值”的“键”，服务器是否知道如何接受 postfields？您可以尝试以下方法吗？ // 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 $data_string to your CURLOPT_POSTFIELDS... 祝你好运。我知道这个问题已经有两年了，但仍然有很多人浏览。这看起来像是 SSL 问题。你可以尝试： curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 有关更多信息，请阅读：http://unitstep.net/blog/2009/05/05/using-curl-in-php-to-access-https-ssltls-protected-sites/ 试试这个功能 function request($url, $data, $method = "POST", $json = true) { $curl = curl_init(); curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 5); if ($json) { $data_value = json_encode($data, JSON_UNESCAPED_UNICODE); curl_setopt($curl, CURLOPT_HTTPHEADER, array( 'Content-Type: application/json', 'Content-Length: '.strlen($data_value))); } else $data_value = http_build_query($data); switch ($method) { case "POST": if ($json) curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST"); else curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $data_value); break; case "PUT": curl_setopt($curl, CURLOPT_PUT, 1); break; default: $url = sprintf("%s?%s", $url, $data_value); } curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); $result = curl_exec($curl); if ($result == false) throw new Exception(curl_error($curl)); curl_close($curl); return $result; } CURLOPT_POSTFIELDS：必须喜欢这个“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(); $content_length = strlen($content); $context = array( 'http' => array( 'method' => 'POST', 'user_agent' => $user_agent, 'header' => 'Content-Type: ' . $content_type . "\r\n" . 'Content-Length: ' . $content_length, 'content' => $content, 'timeout' => 10, ) ); $context_id = stream_context_create($context); $sock = fopen($server_addr, 'r', false, $context_id); $result = ''; if ($sock) { while (!feof($sock)) { $result .= fgets($sock, 4096); } fclose($sock); } return $result; } ?>
