使用PHP cURL POST JSON

Question

我有以下PHP代码

curl_setopt($ch, CURLOPT_URL, $URL);
curl_setopt($ch, CURLOPT_USERAGENT, $this->_agent);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $this->_headers);
curl_setopt($ch, CURLOPT_ENCODING , "gzip");
curl_setopt($ch, CURLOPT_VERBOSE, false); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_TIMEOUT,  120);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, $this->_cookie_file_path);
curl_setopt($ch, CURLOPT_COOKIEJAR, $this->_cookie_file_path);
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}');
curl_setopt($ch, CURLOPT_POST, 1); 

但我不明白为什么不工作.我发布JSON的API表示没有收到参数.我的代码有什么问题吗？我认为整个技巧都是关于JSON参数...我不知道如何发送它们,因为我看不到与http分析器的任何"nave-> value"对,因为它通常以简单的形式出现...只是没有任何"名称"的JSON代码.

您可以尝试如下。基本上，如果我们有一个数据数组，那么它应该json encoded使用 php json_encode。而且你还应该增加content-type在header可在卷曲被定义为curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));

$data = array("country"=>"US","states"=>array("MHASASAS"=>"MH","XYZABABA"=>"XYZ"));
$postdata = json_encode($data);

$ch = curl_init($URL);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$result = curl_exec($ch);
curl_close($ch);

您尚未设置内容类型，因此帖子数据将作为表单数据发送。尝试将内容类型设置为 application/json。

如果这不起作用，请尝试用数组包装 json 字符串。
