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;
}
?>
