使用 Feign Client 时有没有办法添加多个标头

Question

我有一个 Feign 客户端来访问需要两个标头的 createUser 端点：用户名和密码。我知道如何添加一个标头，但如何向请求添加两个标头？

@FeignClient(name = "client", url = "https://abc.abc.com/user/", configuration = FeignClientConfig.class)
public interface MyFeignClient {

@Headers("username_header: {username}")  // how do I add "password" here.
@PostMapping(value = "v1/users")
void createUser((@Param("username") String username, User userRequest);

}

更新：现在根据下面的答案，我将界面主体更改为：

@Headers({"username_header: {username}", "password_header: {password}"}) 
@PostMapping(value = "v1/users")
void createUser(@Param("username") String username, 
                @Param("password") String password,
                User userRequest);

调用它的代码是：

feignClient.createUser("me", "123", userObj);

然后我收到错误：

 org.springframework.beans.factory.BeanCreationException: Error creating bean,
 nested exception is java.lang.IllegalStateException: Method has too many Body parameters: 
 feignClient.createUser(java.lang.String,java.lang.String, User)

Answer 1

标头接受 String[] 作为值...所以

    @Headers({ "username: {username}", "password: {password}" })

应该做的伎俩
