项目使用阿里身份证实名认证查询接口，采用Feign请求外部接口。请求时出现feign.FeignException: status 450错误，网上无此类错误记录。查看Feign打印日志，发现是传参问题，重新请求后问题解决。

项目用到阿里的身份证接口: 身份证实名认证查询接口

我喜欢使用feign来请求项目外部的接口, 定义feign接口, feign设置headers的教程请参考(Spring 使用 feign时设置header信息):

@FeignClient(url = "${identity.host}",
        name="identity",
        fallbackFactory = IdenFallbackFactory.class,
        configuration = {FeignLogConfigurer.class}
)
public interface IdenauthenFeignClient {


    @RequestMapping(value = "/idenAuthentication",
            method = RequestMethod.POST,
            headers = {"Content-Type=application/x-www-form-urlencoded",
                    "charset=UTF-8",
                    "Authorization=APPCODE ${identity.appcode}"
    })
    String getIden(@RequestParam(value = "memberIdNo") String idNo, @RequestParam(value = "memberRealName") String name) throws Exception;
}

请求的时候就报了feign.FeignException: status 450 reading Idenauthen FeignClient错误, 网上没有这类错误出现, 我仔细看了一下feign打印日志:

x-ca-error-message: Required argument idNo : expect [type: String]

发现传参问题有问题

@FeignClient(url = "${identity.host}",
        name="identity",
        fallbackFactory = IdenFallbackFactory.class,
        configuration = {FeignLogConfigurer.class}
)
public interface IdenauthenFeignClient {


    @RequestMapping(value = "/idenAuthentication",
            method = RequestMethod.POST,
            headers = {"Content-Type=application/x-www-form-urlencoded",
                    "charset=UTF-8",
                    "Authorization=APPCODE ${identity.appcode}"
    })
    String getIden(@RequestParam(value = "idNo") String idNo, @RequestParam(value = "name") String name) throws Exception;
}

再次请求一下, 搞定
