用户使用移动的终端完成对所购买商品或者服务的支付功能;分为近场支付(蓝牙支付,刷卡,滴卡),和远程支付(网上支付,短信支付)
都是比较安全.都是大公司的产品.而且这个和金钱之前挂钩;
支付不难.因为是第三方平台的东西.
自己总结一下
支付方法需要的支付参数

RSA密钥生成命令
生成RSA私钥
openssl>genrsa -out rsa_private_key.pem 1024
生成RSA公钥
openssl>rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem
将RSA私钥转换成PKCS8格式
openssl>pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt
注意:“>”符号后面的才是需要输入的命令。
E:\支付\支付宝\支付宝钱包支付接口开发包2.0标准版(20160120)\DEMO\openssl\bin\1目录下有俩个文件
