负载 JWT 结构

Question

我正在尝试设置我的 JWT 令牌，但它与往常一样具有不同的有效负载结构，我该如何设置这种负载结构？

{
  "https://daml.com/ledger-api": {
    "ledgerId": "sandbox",
    "applicationId": "foobar",
    "actAs": ["Alice"]    
  }
}

我只能这样设置：

{           
 "sub": "https://daml.com/ledger-api",
 "ledgerId": "sandbox",
 "applicationId": "foobar",
 "actAs": "[Alice]"
}

我的java代码：

void getJWT() throws UnsupportedEncodingException {
                 
    Claims claims = Jwts.claims().setSubject("https://daml.com/ledger-api");
    claims.put("ledgerId","sandbox");
    claims.put("applicationId", "foobar");
    claims.put("actAs", "[Alice]");
    String jwtToken = Jwts.builder()
            .setClaims(claims)
            .signWith(SignatureAlgorithm.HS256, "sYn2kjibddFAWtnPJ2AFlL8WXmohJMCvigQggaEypa5E=".getBytes("UTF-8"))
            .setHeaderParam("typ", Header.JWT_TYPE)
            .compact();
    System.out.println("The generated jwt token is as follows:" + jwtToken);
}

How can i set this kind of payload structure?

{
  "https://daml.com/ledger-api": {
    "ledgerId": "sandbox",
    "applicationId": "foobar",
    "actAs": ["Alice"]    
  }
}

您可以通过如下所述修改代码轻松实现上述有效负载结构。

void getJWT() throws UnsupportedEncodingException {
    Map<String, String> claims = new HashMap<String, String>();
    claims.put("ledgerId", "sandbox");
    claims.put("applicationId", "foobar");
    claims.put("actAs", "[Alice]");

    Map<String, Object> claimsMap = new HashMap<String, Object>();
    claimsMap.put("https://daml.com/ledger-api", claims);

    String jwtToken = Jwts.builder()
            .setClaims(claimsMap)
            .signWith(SignatureAlgorithm.HS256, "sYn2kjibddFAWtnPJ2AFlL8WXmohJMCvigQggaEypa5E=".getBytes("UTF-8"))
            .setHeaderParam("typ", Header.JWT_TYPE)
            .compact();

    System.out.println("The generated jwt token is as follows:" + jwtToken);
}
