支付宝集成纪录

Posted 2020-08-20

最近在研究支付宝的继承，所以做一下笔记

继承支付宝第一步

第一步：创建应用并获取APPID

创建应用和申请支付宝支付那些就不说了，因为这些一般是不是我们做的事，我从配置密钥那一步说起：

第二步：配置密钥（这步很关键，决定你的成败）

开发者登录开放平台后，找到并进入应用

1、先下载密钥生成器，有mac版hewindow版本的

生成方式一（推荐）：使用支付宝提供的一键生成工具（内附使用说明）

mac版本的工具下载后是这个东西, 下面介绍mac版本的操作步骤

生成

rsa_private_key_pkcs8

rsa_private_key

rsa_public_key

三个文件

支付宝平台的解析：

经过以上步骤，开发者可以在当前文件夹中（OpenSSL运行文件夹），看到app_private_key.pem（开发者RSA私钥）、app_private_key_pkcs8.pem（pkcs8格式开发者RSA私钥）和app_public_key.pem（开发者RSA公钥）3个文件。开发者将私钥保留，将公钥提交给支付宝配置到开发平台，用于验证签名

注意：对于使用Java的开发者，将pkcs8在console中输出的私钥去除头尾、换行和空格，作为开发者私钥，对于.NET和php的开发者来说，无需进行pkcs8命令行操作。

我解析一下上面的文字：

其实 app_public_key.pem 是要上传给支付宝平台的，app_private_key.pem的内容（java是使用app_private_key_pkcs8.pem）是ios程序里面下单的时候填写的 privateKey 参数，要去除头尾（-----BEGIN PRIVATE KEY----- xxx -----END PRIVATE KEY----- ）

例如

-----BEGIN PRIVATE KEY-----

2、点击“RSA(SHA1)密钥”处的“设置开发者公钥”（如已设置则显示“查看开发者公钥”，可修改），将公钥文件去除头尾、换行和空格，仅需填入字符串。

如下图：

到这里，密钥配置完成了

3、iOSdemo里面的集成

4、测试下单

主要是参数要选对

NSString *pid = @"合作伙伴身份（PID)";

NSString *appID = @"APPID（支付宝平台上面有）";

NSString *privateKey = @"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";

privateKey  就是rsa_private_key_pkcs8.pem  中间的内容（去除头尾）

例如：

-----BEGIN PRIVATE KEY-----
