Question

当我尝试发送＆＃34; access_token＆＃34;时遇到问题Lagom HTTP RestCall标题中的参数：

 @Override
public HeaderServiceCall<NotUsed, GetUserInfoWrapperResponse> getUserInfo() {
    return (request, requestBody) -> {
        UUID userId;
        try {
            userId = UUID.fromString(request.getHeader("access_token").get());
            System.out.println("user id = " + userId);
            return userEntityRef(userId).ask(new GetUserInfoCommand()).thenApply(reply -> Pair.create(ResponseHeader.OK, reply.userInfo.get()));
        } catch (Exception e) {
            throw new NotFound("User with access_token ");
        }
    };
}

我总是得到NotFoundException，因为＆＃34; access_token＆＃34;标题中没有。

但是，当我改变＆＃34; access_token＆＃34;通过＆＃34; access-token＆＃34;它有效。

当我做一些研究时，我知道我需要将CrosFilter播放到我的application.conf：

play.http.filters = "com.test.user.impl.AccessFilter"
play.filters.cors {
      // review the values of all these settings to fulfill your needs. These values are not meant for production.
      pathPrefixes = ["/cms"]
      allowedOrigins = null
      allowedHttpMethods = null
      allowedHttpHeaders = ["Origin", "X-Requested-With", "Content-Type", "Accept", "Referer", "User-Agent", "access_token", "cache-control"]
      # The exposed headers
      exposedHeaders = ["Origin", "X-Requested-With", "Content-Type", "Accept", "Referer", "User-Agent", "access_token", "cache-control"]
      supportsCredentials = false
      preflightMaxAge = 6 hour
}

但即便如此，＆＃34; access_token＆＃34;标题参数始终不存在。

有任何帮助吗？请！

这是因为你在名字中使用了下划线;除非you explicitly define them in its config file.

，否则它不会被禁止但不常见，而某些服务器（例如Nginx会丢弃它们）

Lagom：没有值存在＆＃34; access_token＆＃34;标题参数
