文字识别的HTTPS接口在处理图片(未超4M限制)时候返回图片格式错误,很小的图片时返回正常

我使用的服务是:通用文字识别

调用的接口是:基于C++HTTP 的API

参数设置情况:none

开发平台和机型:LINUX ubuntu14.04

SDK版本号:none

代码或日志截图(上传截图能帮助您更快解决问题):

复现步骤、现象及其他描述:

按照官方的参考选择了curl用做HTTPS的请求,代码完全参考了官方提供的例程在图片base64编码内容长度小于1024(猜测),返回结果正常。

如图:

{"log_id": 3540079175, "words_result_num": 1, "words_result": [{"location": {"width": 12, "top": 9, "height": 15, "left": 7}, "words": "8"}]}

但是图片稍微大点(1280*720)就不行了,一直认为图片格式错误:

{"log_id": 192482879, "error_code": 216201, "error_msg": "image format error"}


请问服务器是否对post的请求长度的限制实际上未达到接口文档写了4M


curl开启日志后如图:

是因为你们的图片二进制流 超过了post的字节大小限制

您好, 语音识别的rest api支持的是语音文件的音频到文字的识别, 不支持图片。对于图片ocr接口的使用问题, 请至百度AI的官网http://ai.baidu.com 反馈, 谢谢。
