php curl传json

1.封装的curl公共方法
function curlJson( $url,$data){ //传json post
$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HTTPHEADER, array(‘Content-Type: application/json’)); //设置请求头，这个一定要写
curl_setopt( $ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
return $response;
}

2.调用：
public function dayin(){
$url = ‘http://localhost/xxx/xxx/xxx’; //请求的路径
$string = array( //请求的参数
‘OrderType’=>1,
‘PrintContent’=>1,
‘PrintPaper’=>‘A4’,
‘CorpBillidDatas’=>array(
‘CorpBillid’ => ‘5c3fca6c71ed922e1487311d’
),
‘Verify’=>array(
‘Clientid’ => ‘758’,
‘Token’ => ‘9VdKIr2FB8Jr40XSCBRW’
)
);
$parame = json_encode($string); //参数转成json
$val = curlJson($url,$parame); //调用方法访问接口
return $val; //输出 =返回值
}
