cURL JSON帖子不起作用，并且没有显示错误PHP 7

问题描述：

I have a strange error in which my cURL script in PHP 7 does not seem to work, and does not give an error. My code:

$content = json_encode(array(
    'I was just testing',
    'Whether or not this is working',
        ));

$collatex_url = 'http://localhost:7369/collate';
$collatex_headers = array(
    "Content-type: application/json; charset=UTF-8;",
    "Content-Length: " . strlen($content),
    "Accept: application/json"
);

$curl = curl_init($collatex_url);
curl_setopt($curl, CURLOPT_HTTPHEADER, $collatex_headers);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_VERBOSE, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, array('json' => $content));
//curl_setopt($curl, CURLOPT_POSTFIELDS, array('json=' . urlencode($content))); //tried, also does not work
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($curl);
echo curl_error($curl); //does not produce an error
echo 'THE RESULT IS' . $result; //the result is empty
curl_close($curl);

my Selinux is set to permissive
my cURL module does work, as Ive been able to POST and GET queries from other sources
The program on localhost:7369 is running and working. It does not show any incomming request in its log when executing the cURL command.
I have a server set up with PHP 5, and strangely it does work there..just not on my local dev environment on which I have PHP 7, so Im not sure if PHP 7 is causing the problem, or that I just forgot to configure something.
Both my server and my dev environment are on CentOS 6.7

Any help would be appreciated.

我有一个奇怪的错误，其中我的PHP 7中的cURL脚本似乎不起作用，并且没有给出错误。我的代码： p>

  $ content = json_encode（array（
'我只是在测试'，
'这是否正常工作'，
））; \  n 
 $ collatex_url ='http：// localhost：7369 / collate'; 
 $ collatex_headers = array（
“Content-type：application / json; charset = UTF-8;”，
“Content-Length  ：“。strlen（$ content），
”接受：application / json“
）; 
 
 $ curl = curl_init（$ collatex_url）; 
curl_setopt（$ curl，CURLOPT_HTTPHEADER，$ collatex_headers）; 
curl_setopt（  $ curl，CURLOPT_POST，true）; 
curl_setopt（$ curl，CURLOPT_VERBOSE，true）; 
curl_setopt（$ curl，CURLOPT_POSTFIELDS，array（'json'=＆gt; $ content））; 
 // curl_setopt（$ curl，CURLOPT_POSTFIELDS  ，array（'json ='。urlencode（$ content）））;  //尝试过，也不起作用
curl_setopt（$ curl，CURLOPT_RETURNTRANSFER，true）; 
 $ result = curl_exec（$ curl）; 
echo curl_error（$ curl）;  //不会产生错误
echo'结果是'。  $结果;  //结果为空
 ncurl_close（$ curl）; 
  code>  pre> 
 
 
我的Selinux设置为允许 li> 
 
 我的cURL模块确实有效，因为我已经能够从其他来源发出POST和GET查询 li> 
 
 localhost：7369上的程序正在运行并正在运行。 执行cURL命令时，它不会在其日志中显示任何incomming请求。   li> 
 
我有一个使用PHP 5设置的服务器，奇怪的是它确实在那里工作..不是在我有PHP 7的本地开发环境中，所以我不确定PHP 7是否导致 问题，或者我只是忘了配置一些东西。   li> 
 
我的服务器和我的开发环境都在CentOS 6.7上。 li> 
  ul> 
 
 任何帮助都将不胜感激。   p> 
  div>

答

try by sending the json like this:

curl_setopt($curl, CURLOPT_POSTFIELDS, $content);
