Types

type Crypt

type Crypt struct {
	Token  string
	AesKey []byte
}

Crypt *

• 1.第三方回复加密消息给公众平台；
• 2.第三方收到公众平台发送的消息，验证消息的安全性，并对消息进行解密。

func NewCrypt

func NewCrypt(token, aesKey string) *Crypt

NewCrypt *

• 构造函数
• @param $token string 公众平台上，开发者设置的token
• @param $encodingAesKey string 公众平台上，开发者设置的EncodingAESKey
• @param $appId string 公众平台的appId

func (*Crypt) Decrypt

func (ct *Crypt) Decrypt(signature, timestamp, nonce, encrypt string) ([]byte, error)

Decrypt *

• 检验消息的真实性，并且获取解密后的明文.
• <ol>
• <li>利用收到的密文生成安全签名，进行签名验证</li>
• <li>若验证通过，则提取xml中的加密消息</li>
• <li>对消息进行解密</li>
• </ol> *
• @param signature string 签名串，对应URL参数的msg_signature
• @param timestamp string 时间戳 对应URL参数的timestamp
• @param nonce string 随机串，对应URL参数的nonce
• @param encrypt string 密文 *

func (*Crypt) DecryptMsg

func (ct *Crypt) DecryptMsg(signature, timestamp, nonce, encrypt string) ([]byte, string, error)

DecryptMsg *

• @return @string 正文 @string appid @error

func (*Crypt) Encrypt

func (ct *Crypt) Encrypt(msg, timestamp, nonce string) (string, string, error)

Encrypt *

• 将公众平台回复用户的消息加密打包.
• <ol>
• <li>对要发送的消息进行AES-CBC加密</li>
• <li>生成安全签名</li>
• <li>将消息密文和安全签名打包成xml格式</li>
• </ol> *
• @param msg string 公众平台待回复用户的消息，xml格式的字符串
• @param timeStamp string 时间戳，可以自己生成，也可以用URL参数的timestamp
• @param nonce string 随机串，可以自己生成，也可以用URL参数的nonce *

func (*Crypt) GenerateXmlMsg

func (ct *Crypt) GenerateXmlMsg(msg, timestamp, nonce string) string

GenerateXmlMsg *

• 生成xml消息
• @param string $encrypt 加密后的消息密文
• @param string $signature 安全签名
• @param string $timestamp 时间戳
• @param string $nonce 随机字符串
