PHP语言API示例

本示例以图像标签为例介绍如何使用PHP调用API。

<?php

function TokenRequest() {
    $url = "https://{endpoint}/v2/{project_id}/image/tagging";
    $token = "用户获取得到的实际token值";
    $imagePath = __DIR__.'data/image-tagging.jpg';

    $data = array();
    if (stripos($imagePath, 'http://') !== false || stripos($imagePath, 'https://') !== false) {
        $data['url'] = $imagePath;
    } else {
        if($fp = fopen($imagePath,"rb", 0))
        {
            $gambar = fread($fp,filesize($imagePath));
            fclose($fp);

            $fileBase64 = chunk_split(base64_encode($gambar));
        } else {
            echo "图片读取错误";
            return;
        }
        $data['image'] = $fileBase64;
    }

    $curl = curl_init();
    $headers = array(
        "Content-Type:application/json",
        "X-Auth-Token:" . $token
    );

    /* 设置请求体 */
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($curl, CURLOPT_POST, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($curl, CURLOPT_NOBODY, FALSE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_TIMEOUT, 30);

    $response = curl_exec($curl);
    $status = curl_getinfo($curl, CURLINFO_HTTP_CODE);
    curl_close($curl);
    echo $response;
}

TokenRequest();
