This interface is free for 100 times a day, and it is enough to debug and use it by yourself~
The accuracy of the personal test is not bad.
request address

request parameters
| parameter name | Parameter Description |
|---|---|
| key | The user requests a key, which can be applied on the key management page |
| data | Image base64 encoded data or network image URL |
Request result parameter description
| parameter name | Parameter Description |
|---|---|
| code | status code |
| msg | status information |
| debug | error message |
| exec_time | system execution time |
| user_ip | your ip |
| data | request result dataset |
| data.text | The complete text content recognized (note the line break) |
| data.text_list[] | An array of text results for each line recognized |
POST supports both image url and base64 data submission, get only supports image url submission.
code example
/**
* 图片转Base64
*/
public static String getImageBase() throws Exception {

// 读取图片字节数组
try {

}
// 对字节数组Base64编码
BASE64Encoder encoder = new BASE64Encoder();

}
