接入企业需要联系北极星客服申请OpenAPI的key和secret，之后通过JWT加密算法生成AccessToken，以下为详细生成过程：

Golang版 #

package main

import (
   "fmt"
   "github.com/dgrijalva/jwt-go"
   "time"
)

func main(){
   key := "org key"
   secret := "org secret"

   token := jwt.New(jwt.SigningMethodHS256)
   claims := make(jwt.MapClaims)
   claims["exp"] = time.Now().Add(time.Hour * time.Duration(1)).Unix()
   claims["iat"] = time.Now().Unix()
   claims["_key"] = key
   token.Claims = claims
   accessToken, _ := token.SignedString([]byte(secret))
   fmt.Println(accessToken)
}

Java版 #

import com.auth0.jwt.JWT;
import com.auth0.jwt.algorithms.Algorithm;

public static final Long   EXPIRES_IN = 1 * 3600 * 1000L;
public static final String TOKEN_APPID = "_key";

public static String genAppToken(String appId, String appSecret) {
    if (StringUtils.isEmpty(appId) || StringUtils.isEmpty(appSecret)) {
        return null;
    }

    Algorithm algorithm = Algorithm.HMAC256(appSecret);
    long timestamp = System.currentTimeMillis();
    Date issuedAt = new Date(timestamp);
    Date expiresAt = new Date(timestamp + EXPIRES_IN);

    return JWT.create()
            .withClaim(TOKEN_APPID, appId)
            .withIssuedAt(issuedAt)
            .withExpiresAt(expiresAt)
            .sign(algorithm);
}

OpenAPI所有接口需要在请求头中携带认证参数：
