使用Feign配置請(qǐng)求頭以及支持Https協(xié)議

更新時(shí)間：2022年03月07日 15:22:02 作者：Hubert-hui

這篇文章主要介紹了使用Feign配置請(qǐng)求頭以及支持Https協(xié)議，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。如有錯(cuò)誤或未考慮完全的地方，望不吝賜教

Feign配置請(qǐng)求頭及支持Https協(xié)議

背景

最近跟第三方對(duì)接，請(qǐng)求頭需要特殊處理，同時(shí)是 Https 協(xié)議。

第三方提供的是使用 OkHttp 調(diào)用。同時(shí)呢，使用 OkHttp 封裝了調(diào)用和返回值。

今天對(duì)項(xiàng)目代碼進(jìn)行審查的時(shí)候，想著還是把這個(gè)替換調(diào)吧，實(shí)現(xiàn)起來更加的優(yōu)雅。

Feign配置請(qǐng)求頭

FeignParamsInterceptor 這個(gè)類實(shí)現(xiàn)了 RequestInterceptor ，可以實(shí)現(xiàn)對(duì)請(qǐng)求進(jìn)行攔截處理。

Feign支持Https協(xié)議

如下 FeignHttpsConfig 類內(nèi)容：這個(gè)方案呢，目前是可以實(shí)現(xiàn)效果的。具體的內(nèi)容是否可以簡化，優(yōu)化。這個(gè)還沒有具體的研究。

本文的解決方案是有問題的。請(qǐng)點(diǎn)擊這里

Feign client 設(shè)置請(qǐng)求頭信息

Feign client端

@FeignClient(url = "${test.url}", name = "cclient",configuration= ClientConfiguration.class,fallback = APIClientFallback.class)
public interface APIClient {?? ??? ?
?? ?
?? ?@RequestMapping(method = RequestMethod.POST, value = "/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 = "/userstaus/test")
?? ?String inusetime(@RequestParam("sendTelNo") String sendTelNo);?? ?
?? ?
?? ?@RequestMapping(method = RequestMethod.POST, value = "/userstaus/test")
?? ?String offnetIdentify(@RequestParam("sendTelNo") String sendTelNo,@RequestParam("date") String date);

配置文件 application-dev.yml

test:
? ? ? url: https://xxxxxx:8243/test
? ? ? tokenId: 11111112222222?

feign configuration 這里配置全局的請(qǐng)求頭和token

@Configuration
public class ClientConfiguration {
?? ?
?? ?@Value("${test.tokenId}")
?? ?private String tokenId;
?? ?
?? ?@Bean
? ? public RequestInterceptor headerInterceptor() {
?? ??? ?return new RequestInterceptor(){
?? ??? ??? ?@Override
?? ??? ??? ?public void apply(RequestTemplate template) {
?? ??? ??? ??? ?List<String> authorizationList = Lists.newArrayList("Bearer "+tokenId);
?? ??? ??? ??? ?List<String> contentTypeList = Lists.newArrayList("application/x-www-form-urlencoded;charset=utf-8");
?? ??? ??? ??? ?Map<String, Collection<String>> headers =ImmutableMap.of("Authorization", authorizationList,"Content-Type", contentTypeList);
?? ??? ??? ??? ?template.headers(headers);
?? ??? ??? ?}
?? ??? ?};
?? ?}

feign 異常處理

@Component
public class APIClientFallback implements APIClient{
?? ?@Override
?? ?public String checkResult(String sendTelNo, String certType, String certCode, String userName) {
?? ??? ?return toJsonString();
?? ?}
?? ?@Override
?? ?public String inusetime(String sendTelNo) {
?? ??? ?return toJsonString();
?? ?}
?? ?@Override
?? ?public 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;
?? ?}
}
