本来是学着使用tesserocr来识别验证码的,但是由于tesserocr的识别率不高,还是学了一下使用云打码来识别验证码==
具体步骤如下:
2、下载后解压,可以看到有如下几个文件,因为我使用的python版本是3.5,所以打开ydmhttpdemo3.x:
3、打开之后修改如下几个部分,用户名和密码就是你的用户名和密码,而appid和appkey需要进入开发者后台查看,第一次使用的时候还需要新建一个软件,才能有appid和appkey:
下图中的软件代码就是appid,通讯密钥就是appkey:
4、把信息都添加进去后运行代码,不出意外会返回一个1007,进入错误代码及排错(http://www.yundama.com/apidoc/ydm_errorcode.html)查找原因,原来是因为账户没有余额
然后进入用户后台充值就行了,充值完以后再次运行代码,就可以看到识别结果了。
进行完如上步骤之后,我们就可以使用云打码平台来识别验证码了,不过为了使用方便,可以建一个ydmdemo.py,把账号密码等信息写进去,调用的时候只需要传入验证码图片就行了。
