Feign 客户端抛出 401

【问题标题】：Feign client throwing 401Feign 客户端抛出 401
【发布时间】：2020-09-10 13:12:48
【问题描述】：

我正在尝试从我的应用程序 （在我的本地运行机）。该 API 在 postman 上执行时运行良好。

curl --location --request POST 'https://myserver.com' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--header 'Accept: application/json' \
--data-urlencode 'client_id=12345****67890' \
--data-urlencode 'client_secret=123456&&&&&5678**90' \
--data-urlencode 'grant_type=abcd' \
--data-urlencode 'token_format=jwt'

但是当我尝试通过 Feign 时它失败了。

@FeignClient( name = "test", url = "https://myserver.com", configuration = FeignSimpleEncoderConfig.class )
public interface AuthFeinClient {

    @PostMapping( value = "/uaa/oauth/token", consumes = "application/json" )
    @Headers( "Content-Type: application/x-www-form-urlencoded" )
    ResponseEntity<String> getAuthToken( @RequestBody Map<String, String> formData );
}

现在我在调用接口方法

Map<String, String> formData = new HashMap<>();
                formData.put("client_id", "12345****67890");
                formData.put("client_secret", "123456&&&&&5678**90");
                formData.put("grant_type", "abcd");
                formData.put("token_format", "jwt");

    ResponseEntity<String> authToken = feignClient.getAuthToken(formData);

我正在map 中发送表单数据。我也试过MultiValueMap。但是同样的错误即将到来。

我还设置了编码器来发送表单数据，

@Configuration
public class FeignSimpleEncoderConfig {

    @Autowired
    private ObjectFactory<HttpMessageConverters> messageConverters;

    @Bean
    FormEncoder feignFormEncoder()
    {
        return new FormEncoder(new SpringEncoder(this.messageConverters));
    }
}

我在这里做错了什么？

【问题讨论】：

  • 你必须在你的主类中使用注解@EnableFeignClients。
  • 它就在那里。我已经注释了
  • 我认为 401 表示表单数据未按预期到达第三位
  • 是的，它是客户端 ID 和客户端密码。它们没有被注入您的请求中。
  • 我将其设置在地图中并发送。

【解决方案1】：

我之前也遇到过这个问题。我可以使用 OkHttpClient 或 curl 请求，但不能使用 FeignClient。这是我的解决方案，它对我有用，我希望它也对你有用。

@Configuration
@ConditionalOnClass(Feign.class)
@AutoConfigureBefore(FeignAutoConfiguration.class)
public class FeignOkHttpConfig {
    @Bean
    public okhttp3.OkHttpClient okHttpClient(){
        return new okhttp3.OkHttpClient.Builder()
                .readTimeout(60, TimeUnit.SECONDS)
                .connectTimeout(60, TimeUnit.SECONDS)
                .writeTimeout(120, TimeUnit.SECONDS)
                .connectionPool(new ConnectionPool())
                .build();
    }

    @Bean
    @ConditionalOnMissingBean({Client.class})
    public Client feignClient(okhttp3.OkHttpClient client) {
        return new feign.okhttp.OkHttpClient(client);
    }

    @Bean
    @ConditionalOnMissingBean({ConnectionPool.class})
    public ConnectionPool httpClientConnectionPool(FeignHttpClientProperties httpClientProperties, OkHttpClientConnectionPoolFactory connectionPoolFactory) {
        Integer maxTotalConnections = httpClientProperties.getMaxConnections();
        Long timeToLive = httpClientProperties.getTimeToLive();
        TimeUnit ttlUnit = httpClientProperties.getTimeToLiveUnit();
        return connectionPoolFactory.create(maxTotalConnections, timeToLive, ttlUnit);
    }

    @Bean
    public OkHttpClient client(OkHttpClientFactory httpClientFactory, ConnectionPool connectionPool, FeignHttpClientProperties httpClientProperties) {
        Boolean followRedirects = httpClientProperties.isFollowRedirects();
        Integer connectTimeout = httpClientProperties.getConnectionTimeout();
        Boolean disableSslValidation = httpClientProperties.isDisableSslValidation();
        return httpClientFactory.createBuilder(disableSslValidation)
                .connectTimeout((long)connectTimeout, TimeUnit.MILLISECONDS)
                .followRedirects(followRedirects)
                .connectionPool(connectionPool)
                .build();
    }
}

通过我的调试，默认调用FeignClient的default-Client发起请求，所以我们可以通过上面的配置强制它使用OkHttpClient。

最后，请原谅我的英文不是很好。 更重要的是springboot的配置代码。
