'How to solve "I/O error on POST request" from restTemplate

higuys!

I have a problem with restTemplate right now. There are two requests while using this restTemplate. First one is simple like login. Other one(the problem) is sending quite long text with post body.

If I send the request on Postman, it works well. I think the length of string might be the problem, but I'm not sure.

Request Parameter is

{
    "name"  : "test",
    "age"   : 28,
    "gender" : 2,
    "type"  : 1,
    "store" : "test2",
    "imgLen" : 2876,
    "img" : "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"

How can I solve this problem?

Thank you!

Solution 1:[1]

Hi Julia This quite feels like the protocol issue. The AWS is fully TLS 1.2 or higher supporting, but the client is not. The Rest Template if not configured otherwise, will start negotiation with TLS 1.0. You have to forcefully make the client to connect only with 1.2 or 1.3 protocol stacks.

 SSLContext context = SSLContext.getInstance("TLSv1.2");
context.init(null, null, null);

CloseableHttpClient httpClient = HttpClientBuilder.create().setSSLContext(context)
    .build();
HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(httpClient);
RestTemplate restTemplate = new RestTemplate(factory);

I/O error on POST request for "http://{ip}:{port}/face/emp"

It seems you do not set a valid host:port

Check your host and reqUri

UriComponents uri = UriComponentsBuilder.fromHttpUrl(host+reqUri).build();
