如何用php调用外部接口json数据？

Question

json数据文件格式如下，从链接中可以获取：http://api.dataoke.com/index....
这些数据都是从网站接口过来的，我的网站使用Php原生态写的，怎么把这些数据输出到前台html里面去呢？

Answer 1

function get($url){
    $ch = curl_init();

　　//设置选项，包括URL
　　curl_setopt($ch, CURLOPT_URL, $url);
　　curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
　　curl_setopt($ch, CURLOPT_HEADER, 0);

　　//执行并获取HTML文档内容
　　$output = curl_exec($ch);

　　//释放curl句柄
　　curl_close($ch);
    return $output;

}

$content=get('http://api.dataoke.com/index.php?r=Port/index&type=total&appkey=0vutvy4tsg&v=2&page=1');
$data=json_decode($content,true);//$data就是最终的数据 而且已经转换成了数组

Answer 2

curl去请求这个地址过去啊

Answer 3

$url="http://api.dataoke.com/index.phpr=Port/index&type=total&appkey=0vutvy4tsg&v=2&page=1";
$content = file_get_contents($url);
$data = json_decode($content,true);

Answer 4

可以自己封装个方法 主要是curl方法

/**
 * 发送HTTP请求方法
 * @param  string $url    请求URL
 * @param  array  $params 请求参数
 * @param  string $method 请求方法GET/POST
 * @return array  $data   响应数据
 */
function httpCurl($url, $params, $method = 'POST', $header = array(), $multi = false){
    date_default_timezone_set('PRC');
    $opts = array(
            CURLOPT_TIMEOUT        => 30,
            CURLOPT_RETURNTRANSFER => 1,
            CURLOPT_SSL_VERIFYPEER => false,
            CURLOPT_SSL_VERIFYHOST => false,
            CURLOPT_HTTPHEADER     => $header,
            CURLOPT_COOKIESESSION  => true,
            CURLOPT_FOLLOWLOCATION => 1,
            CURLOPT_COOKIE         =>session_name().'='.session_id(),
    );
    /* 根据请求类型设置特定参数 */
    switch(strtoupper($method)){
        case 'GET':
           // $opts[CURLOPT_URL] = $url . '?' . http_build_query($params);
           // 链接后拼接参数  &  非？
            $opts[CURLOPT_URL] = $url . '&' . http_build_query($params);
            break;
        case 'POST':
            //判断是否传输文件
            $params = $multi ? $params : http_build_query($params);
            $opts[CURLOPT_URL] = $url;
            $opts[CURLOPT_POST] = 1;
            $opts[CURLOPT_POSTFIELDS] = $params;
            break;
        default:
            throw new Exception('不支持的请求方式！');
    }
    /* 初始化并执行curl请求 */
    $ch = curl_init();
    curl_setopt_array($ch, $opts);
    $data  = curl_exec($ch);
    $error = curl_error($ch);
    curl_close($ch);
    if($error) throw new Exception('请求发生错误：' . $error);
    return  $data;
 }
