How to submit json data with curl

最近在开发一个接口对接的网站,对方的系统用的java开发的,我这里开发用php开发,提交数据的时候用的json格式

为此在网上找了一下curl提交json数据的代码

在此记录一下 推荐:《PHP教程》 

/**
 * 远程获取数据,POST json数据
 * 注意:
 * 1.使用Crul需要修改服务器中php.ini文件的设置,找到php_curl.dll去掉前面的";"就行了
 * 2.文件夹中cacert.pem是SSL证书请保证其路径有效,目前默认路径是:getcwd().'\\cacert.pem'
 * @param $url 指定URL完整路径地址
 * @param $cacert_url 指定当前工作目录绝对路径
 * @param $para 请求的数据 数组
 * @param $input_charset 编码格式。默认值:空值
 * return 远程输出的数据
 */
function getHttpResponsePOSTjson($url, $para, $cacert_url='', $input_charset = '') {
    if (trim($input_charset) != '') {
        $url = $url."_input_charset=".$input_charset;
    }
    $data_string=json_encode($para,JSON_HEX_TAG | JSON_HEX_APOS | JSON_HEX_QUOT | JSON_HEX_AMP | JSON_UNESCAPED_UNICODE);
    $curl = curl_init($url);
    curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($curl, CURLOPT_POSTFIELDS, $data_string);//$data JSON类型字符串
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);//SSL证书认证
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);//严格认证
    curl_setopt($curl, CURLOPT_CAINFO,$cacert_url);//证书地址
    curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Content-Length: ' . strlen($data_string)));
    $result = curl_exec($curl);
    curl_close($curl);
    return $result;
}
Copy after login
