Feign配置请求头及支持Https协议
背景
最近跟第三方对接,请求头需要特殊处理,同时是 Https 协议。
第三方提供的是使用 OkHttp 调用。同时呢,使用 OkHttp 封装了调用和返回值。
今天对项目代码进行审查的时候,想着还是把这个替换调吧,实现起来更加的优雅。
Feign配置请求头
FeignParamsInterceptor 这个类实现了 RequestInterceptor ,可以实现对请求进行拦截处理。
import com.alibaba.fastjson.JSON; import com.alibaba.fastjson.JSONObject; import feign.RequestInterceptor; import feign.RequestTemplate; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Component; import java.io.UnsupportedEncodingException; /** * @Description feign参数拦截 */@Componentpublic class FeignParamsInterceptor implements RequestInterceptor { private static final Logger logger = LoggerFactory.getLogger(FeignParamsInterceptor.class); private static final String loanUrl = "x/"; private static final String accountUrl = "y/"; @Value("${xxxx}")private String clientSecret; @Value("${yyyy}")private String clientId; @Overridepublic void apply(RequestTemplate requestTemplate) {String url = requestTemplate.url(); if (url.contains(loanUrl) || url.contains(accountUrl)) {//获取请求体byte[] body = requestTemplate.body(); JSONObject params; try {params = JSON.parseObject(new String(body, requestTemplate.charset() == null ? "utf-8": requestTemplate.charset().name())); //设置请求体requestTemplate.body(params.toJSONString()); requestTemplate.header("xx", CryptoEncrypt.signBytes(params.toJSONString().getBytes(), clientSecret.getBytes())); requestTemplate.header("yyyy", clientId); requestTemplate.header("Content-Type", "application/json; charset=utf-8"); } catch (UnsupportedEncodingException e) {logger.info(e.getMessage(), e); }}} }
Feign支持Https协议
如下 FeignHttpsConfig 类内容:这个方案呢,目前是可以实现效果的。具体的内容是否可以简化,优化。这个还没有具体的研究。

Feign client 设置请求头信息
Feign client端
@FeignClient(url = "${test.url}", name = "cclient",configuration= ClientConfiguration.class,fallback = APIClientFallback.class)public interface APIClient {@RequestMapping(method = RequestMethod.POST, value = "https://www.it610.com/check/test")String checkResult(@RequestParam("sendTelNo") String sendTelNo,@RequestParam("certType") String certType,@RequestParam("certCode") String certCode,@RequestParam("userName") String userName); @RequestMapping(method = RequestMethod.POST, value = "https://www.it610.com/userstaus/test")String inusetime(@RequestParam("sendTelNo") String sendTelNo); @RequestMapping(method = RequestMethod.POST, value = "https://www.it610.com/userstaus/test")String offnetIdentify(@RequestParam("sendTelNo") String sendTelNo,@RequestParam("date") String date);
配置文件 application-dev.yml
test:url: https://xxxxxx:8243/testtokenId: 11111112222222
feign configuration 这里配置全局的请求头和token
@Configurationpublic class ClientConfiguration {@Value("${test.tokenId}")private String tokenId; @Beanpublic RequestInterceptor headerInterceptor() {return new RequestInterceptor(){@Overridepublic void apply(RequestTemplate template) {List authorizationList = Lists.newArrayList("Bearer "+tokenId); List contentTypeList = Lists.newArrayList("application/x-www-form-urlencoded; charset=utf-8"); Map> headers =ImmutableMap.of("Authorization", authorizationList,"Content-Type", contentTypeList); template.headers(headers); }}; }
feign 异常处理
@Componentpublic class APIClientFallback implements APIClient{@Overridepublic String checkResult(String sendTelNo, String certType, String certCode, String userName) {return toJsonString(); }@Overridepublic String inusetime(String sendTelNo) {return toJsonString(); }@Overridepublic String offnetIdentify(String sendTelNo, String date) {return toJsonString(); }private String toJsonString() {BaseResult resultVo = new BaseResult(); resultVo.renderStatus(ResultTypeEnum.SERVICE_ERROR); ObjectMapper mapper = new ObjectMapper(); try {return mapper.writeValueAsString(resultVo); } catch (JsonProcessingException e) {e.printStackTrace(); }return null; }}
