feign.RetryableException: Incomplete output stream executing POST

[tangchen-blip]

An error occurred when I overwrote the headers using RequestInterceptor.

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
            <version>2.1.2.RELEASE</version>
            <scope>compile</scope>
        </dependency>

RequestInterceptor.java

@Configuration
@Slf4j
public class FeignHeadConfiguration implements RequestInterceptor {

    @Override
    public void apply(RequestTemplate requestTemplate) {
        ServletRequestAttributes attrs = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attrs.getRequest();
        Enumeration<String> headerNames = request.getHeaderNames();
        if (headerNames != null) {
            while (headerNames.hasMoreElements()) {
                String name = headerNames.nextElement();
                String value = request.getHeader(name);
                log.info("name:{},value:{}", name, value);
                requestTemplate.header(name, value);
            }
        }
    }
}

Getting the same issue while doing an POST Request!

@FeignClient(name = "redis-service") public interface RedisProxy { @PostMapping(value = "redis/storeAuthSession", consumes = MediaType.APPLICATION_JSON_VALUE) void storeAuthSessionData(@RequestBody AuthSessionData authSessionData); }

[tangchen-blip]

remove the header param content-length can resolve it

[g4ur4vs]

yes..resolved thanks!!

[OlgaMaciaszek]

Closing as issue resolved.

[mohdtabish999]

headers.remove("content-length");
outputMessage = xyzClient.save(headers, message);

removing content-length resolved the issue

[scruel]

Closing as issue resolved.

Resolved? This issue caused by feign code...

[XWTiger]

it

remove the header param content-length can resolve it

it work

[iamyuzhe]

remove the header param content-length can resolve it

how to remove the header param, I don't understand it, can you explain it in detail?

[jyotinpo]

It seems Feign client generates and add its own Content-Length header. Hence for each request two Content-Length headers got added during the API calls which caused this issue.

Intercepting the request and removing one Content-Length header resolved the issue.

Hello @jyotinpo, please provide a minimal, complete, verifiable example that reproduces the issue.
