请求说明
请求示例
http 方法:post
请求url: https://aip.baidubce.com/rest/2.0/ocr/v1/passport
url参数:
参数 | 值 |
---|---|
access_token | 通过api key和secret key获取的access_token,参考“” |
header如下:
参数 | 值 |
---|---|
content-type | application/x-www-form-urlencoded |
body中放置请求参数,参数详情如下:
请求参数
参数 | 是否必选 | 类型 | 可选值范围 | 说明 |
---|---|---|---|---|
image | 和url二选一 | string | - | 图像数据,base64编码后进行urlencode,需去掉编码头(data:image/jpeg;base64, ) 要求base64编码和urlencode后大小不超过4m,最短边至少15px,最长边最大4096px,支持jpg/jpeg/png/bmp格式 |
url | 和image二选一 | string | - | 图片完整url,url长度不超过1024字节,url对应的图片base64编码后大小不超过4m,最短边至少15px,最长边最大4096px,支持jpg/jpeg/png/bmp格式,当image字段存在时url字段失效 请注意关闭url防盗链 |
