2.请求参数
字段 | 类型 | 必需 | 描述 |
---|---|---|---|
api_id | string | 是 | API 账户 |
api_secret | string | 是 | API 密钥 |
file | file | 见下方注释 | 需上传的图片文件。上传本地图片进行检测时选取此参数 |
url | string | 见下方注释 | 图片网络地址。采用抓取网络图片方式时需选取此参数 |
image_id | string | 见下方注释 | 图片的id。在云端上传过图片可采用 |
auto_rotate | boolean | 否 | 开启图片自动旋转功能。开通:true,不开通:false。默认不开通 |
请求参数
file
,url
与image_id
三选一。url 中含有不少特殊字符,若将 URL 放入 Query String 中则需要对这些字符进行转义,所有中文和特殊字符必需以UTF-8编码转义。 目前支持 http/https 等协议的网络地址。下载限时 5s,超时后仍未下载完成则属于失败。 参数
