Question

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....

Answer 1

$data = [
    "api_key" => "{$api_key}",
    "api_secret" => "{$api_secret}",
    "image_url" => "$image_url",//不加@
    "return_landmark" => "{$return_landmark}",
    "return_attributes" => "{$return_attributes}"
];

//上传本地文件
$data = [
    "api_key" => "{$api_key}",
    "api_secret" => "{$api_secret}",
    "image_file" => new CURLFile(realpath('test.jpg')),
    "return_landmark" => "{$return_landmark}",
    "return_attributes" => "{$return_attributes}"
];
//返回数组比较大
