按照微信企业付款到银行卡接口文档,调用转账接口后,返回的XML:
10000
目前我的问题仍没有解决,我把我实现的主要代码和过程贴出来,大家交流下,问题出在哪里。
第一步,获取微信公钥,调用https://fraud.mch.weixin.qq.com/risk/getpublickey 接口,返回的是
-----BEGIN RSA PUBLIC KEY----- 开头的字符串,将此字符串存为文件,例如文件名为wx_pubkey2048.pem (PKCS#1格式)。
第二步:
将PKCS#1格式文件转换为 PKCS#8格式,使用下面的命令:
openssl rsa -RSAPublicKey_in -in wx_pubkey2048.pem -pubout
此命令会生成-----BEGIN PUBLIC KEY-----开头,-----END PUBLIC KEY-----结尾的字符串,将字符串建立一个新文件例如ps8.pem存储起来,
-----BEGIN PUBLIC KEY----- 是第一行 ,-----END PUBLIC KEY-----是末尾一行,中间是一长串字符串。
第三步,我从网上抄了一个RSA的程序,出处忘记了,大家参考一下:

最后返回的是:

失败的原因是RSA调用存在问题,还是真的是缺少省份或城市信息啊?微信参数中没有城市参数。请教下接口调通的朋友,你们的接口参数传了哪些,是不是我的漏了,还是我找的RSA算法有问题?按理说,如果RSA加密参数有问题,微信是不能正常解析出正确的银行卡号和账户名的,会报卡号和账户名错误的问题。
