OAuth2获取token原生方法

服务内部通过feign调用/oauth/token方法

创建FeignClient接口类

import com.goldnet.core.launch.constant.AppConstant;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.util.MultiValueMap;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

/**
 * @Author 
 * @Date 2020/12/9 11:50
 * @Version 1.0
 */
@FeignClient(
	value = AppConstant.APPLICATION_AUTH_NAME,
	fallback = AuthFeignClientFallback.class
)
public interface AuthFeignClient {
	@RequestMapping(method = RequestMethod.POST, value = "/oauth/token")
	Object postAccessToken(@RequestParam MultiValueMap<String, String> parameters, @RequestHeader MultiValueMap<String, String> headers);
}

import org.springframework.stereotype.Component;
import org.springframework.util.MultiValueMap;

/**
 * @Author 
 * @Date 2020/12/9 14:45
 * @Version 1.0
 */
@Component
public class AuthFeignClientFallback implements AuthFeignClient {
	@Override
	public Object postAccessToken(MultiValueMap<String, String> map) {
		return "获取token失败";
	}
}

参数解释：

AppConstant.APPLICATION_AUTH_NAME 服务提供者的服务名
"aHg6aHhfc2VjcmV0" 是client_id:client_secret 通过base64编码获得----项目要求，视情况而定
Tenant-Id 租户id----项目要求，视情况而定

调用方法

HttpServletRequest request = WebUtil.getRequest();
String tenantId = request.getHeader("Tenant-Id");
String authorization = request.getHeader("Authorization");
MultiValueMap<String,String> headers = new LinkedMultiValueMap<>();
headers.add("Content-Type","multipart/form-data");
headers.add("Authorization",authorization);
headers.add("Tenant-Id",tenantId);
//body
MultiValueMap<String,String> body = new LinkedMultiValueMap<>();
body.add("username","11");
body.add("password","11");
body.add("grant_type","password");
//调用auth服务
log.info("[接口名称：调用auth][请求数据body：{}][请求数据headers：{}]",body,headers);
Object token = oAuthFeignClient.postAccessToken(body, headers);
