英文:
How to get JWT Token from RequestHeader
问题
[![在这里输入图片描述][1]][1]我试图从get请求的头部获取我的Bearer令牌。如果我想要显示令牌，那么就会返回NULL。有人知道为什么我没有获得令牌吗？
```java
public String sendSmsToCustomer(HttpServletRequest request, @PathVariable("name") String name, @PathVariable("customer_phone_number") String customer_phone_number, @PathVariable("text") String text) throws Exception {
String user = request.getHeader("Authorization");
System.out.println(user);
}
更新 1
public static String getUsernameFromToken(HttpServletRequest request) {
String token = request.getHeader(HEADER_STRING);
String user = null;
if (token != null) {
// 解析令牌。
try {
user = Jwts.parser()
.setSigningKey(SECRET)
.parseClaimsJws(token.replace(TOKEN_PREFIX, ""))
.getBody()
.getSubject();
} catch (Exception e) {
throw e;
}
return user;
} else
return null;
}
更新 2
@GetMapping("/contacts/token")
public String getToken(HttpServletRequest request) throws Exception {
String user = request.getHeader(HEADER_STRING);
System.out.println(user);
return user;
}
更新 3
在我获得完整的头部输出后，我发现 "Authorization" 不可用。
{
"x-forwarded-host": "localhost:8800",
"x-forwarded-proto": "http",
"x-forwarded-prefix": "/contacts",
"postman-token": "081ea72c-e270-46db-8703-e5afc9887ba1",
"host": "localhost:8100",
"x-forwarded-port": "8800",
"content-type": "application/json",
"connection": "Keep-Alive",
"x-forwarded-for": "0:0:0:0:0:0:0:1",
"accept-encoding": "gzip, deflate, br",
"user-agent": "PostmanRuntime/7.26.2",
"accept": "*/*"
}
因此，我将无法在那里找到令牌。也许是我的依赖关系吗？我只集成了 jjwt 用于令牌。有人有解决方案吗？我已经为这个错误困扰了几个小时。

I try to get my bearer token from the header of the getrequest. If I want to display the token, then NULL is returned. Does anyone have any idea why I don't get the token?
public String sendSmsToCustomer(HttpServletRequest request, @PathVariable("name") String name,@PathVariable("customer_phone_number") String customer_phone_number, @PathVariable("text") String text) throws Exception
{
String user = request.getHeader("Authorization");
System.out.println(user);
UPDATE 1
public static String getUsernameFromToken(HttpServletRequest request) {
String token = request.getHeader(HEADER_STRING);
String user = null;
if (token != null) {
// parse the token.
try {
user = Jwts.parser()
.setSigningKey(SECRET)
.parseClaimsJws(token.replace(TOKEN_PREFIX, ""))
.getBody()
.getSubject();
} catch (Exception e) {
throw e;
}
return user;
}
else
return null;
}
UPDATE 2
@GetMapping("/contacts/token")
public String getToken(HttpServletRequest request) throws Exception
{
String user = request.getHeader(HEADER_STRING);
System.out.println(user);
return user;
}
UPDATE 3
After I have had the complete header output, I see that "Authorization" is not available.
{
"x-forwarded-host": "localhost:8800",
"x-forwarded-proto": "http",
"x-forwarded-prefix": "/contacts",
"postman-token": "081ea72c-e270-46db-8703-e5afc9887ba1",
"host": "localhost:8100",
"x-forwarded-port": "8800",
"content-type": "application/json",
"connection": "Keep-Alive",
"x-forwarded-for": "0:0:0:0:0:0:0:1",
"accept-encoding": "gzip, deflate, br",
"user-agent": "PostmanRuntime/7.26.2",
"accept": "*/*"
}
Therefore I will not be able to find the token there either. Is it maybe my dependencies? I only integrated the jjwt dependency for the token. Does anyone have a solution? Been sitting on this bug for several hours

你应该提供给我们你正在发送的请求，以便检查令牌是否已发送。
也许你可以尝试通过添加这个头部来接收它，像这样：
@RequestHeader("Authorization") String token
英文:
You should provide us the request you are sending to check if the token was send.
Maybe you can also try receiving it like this by adding this header
@RequestHeader("Authorization") String token

如果request是请求对象，则可以执行以下操作：
request.getHeader(HttpHeaders.AUTHORIZATION);
英文:
If request is the Request object, then you can do:
request.getHeader(HttpHeaders.AUTHORIZATION);
