Feign配置请求头以及支持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。同事呢,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。

一、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 */ @Component public 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; @Override public 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); } } }}

二、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。
本文的解决方案是有问题的。请点击这里
