PHP:用Face++ 接口的问题-PHP中文网问答

1.问题
当image_url参数我换了什么图片链接都会出现
{"time_used": 35, "error_message": "INVALID_IMAGE_URL", "request_id": "1490261884,fc7b3994-1be7-412e-b7ae-6ff17ddffe61"}
2.官方参考文档
https://console.faceplusplus....
官方的PHP参考例子是2015年的
一些参数变了很多

3.我的代码

 "{$api_key}",
    "api_secret" => "{$api_secret}",
    "image_url" => "@$image_url",
    "return_landmark" => "{$return_landmark}",
    "return_attributes" => "{$return_attributes}"
];

//初始化一个cURL会话
$ch = curl_init();

//
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // 对认证证书来源的检查
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2); // 从证书中检查SSL加密算法是否存在

//设置请求选项
curl_setopt($ch, CURLOPT_URL, $detect_api_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER,0);

//这是请求类型
curl_setopt($ch, CURLOPT_POST, TRUE);
//添加post数据到请求中
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

$response = curl_exec($ch);

//错误处理
if($response == FALSE){
    echo "错误信息:".curl_error($ch)."
";
}
//获取curl请求的具体信息
$curl_info = curl_getinfo($ch);
echo "收到的http回复的code:".$curl_info["http_code"]."
";
//


curl_close($ch);
//输出返回信息
var_dump($response);
