另一种方法

    public function getPost(){
        $url=$data['url'];  //请求地址
        $data=json_encode([
                    'begin_date'=>'20210501',
                    'end_date'=>'20210501'
                ]);
        $opts=[
            'http'=>[
                'method'=>'POST',
                'header'=>[
                    'Content-Type:application/json',
                    'Charset:utf8'
                ],
                'content'=>$data
                ]
            ];
        $context=stream_context_create($opts);
        $jsondata=file_get_contents($url,false,$context);
        return $jsondata;
    }

　　

还有一种方法  表单传值跳转

echo "<form style='display:none;' id='form1' name='form1' method='post' action='https://www.zhix.net/'>
      <input name='goodsname' type='text' value='".$goodsname."' />
      <input name='istype' type='text' value='".$istype."'/>
      <input name='key' type='text' value='".$key."'/>
      <input name='notify_url' type='text' value='".$notify_url."'/>
      <input name='orderid' type='text' value='".$orderid."'/>
      <input name='orderuid' type='text' value='".$orderuid."'/>
		  <input name='return_url' type='text' value='".$return_url."'/>
		  <input name='price' type='text' value='".$price."'/>
		  <input name='uid' type='text' value='".$uid."'/>
      </form>
      <script type='text/javascript'>function load_submit(){document.form1.submit()}load_submit();</script>";
