Java library for Consul HTTP API

[Vasily Vasilkov]

Hi everyone!

Thank you for Consul, it is a very interesting and useful tool for us here, at Ecwid.

Consul HTTP API is great and very functional, but we need to use it more effectively with our Java-based services. We wrote a Java client for Consul HTTP API, you can find it here: https://github.com/Ecwid/consul-api

Our client supports all HTTP endpoints, all consistency modes and request parameters (tags, datacenters etc.)

Please, feel free to ask any questions, report bugs or make pull requests.

Thank you!

Thanks for sharing this! This is the most complete Java client (or even non-Go) client

I think I’ve seen so far. I’ll be sure to point people to this when they ask for a Java client!

Best Regards,

Armon Dadgar

Vasily,

Thank you for the API.

Maybe you can add some more documentation, is possible.

I am having trouble with simple string key-value use cases.

Following Java code

ConsulClient client = new ConsulClient("127.0.0.1");
    client.setKVValue("someKey", "someKeyValue");

stores in Consul:

[{"CreateIndex":10299,"ModifyIndex":10376,"LockIndex":0,"Key":"someKey","Flags":0,"Value":"c29tZUtleVZhbHVl"}]

and the Java code:

client.getKVValue("someKey").getValue().getValue();

 

then retrieves the String "c29tZUtleVZhbHVl" instead of "someKeyValue"

What am I missing? How do I retrieve the value?

Thank you!

I'm pretty sure I answered this in IRC, but for the record, the step you're missing is un-Base64ing the value.

Ryan is correct.

What you need to do is just decode:

String value = new String(Base64.decodeBase64(client.getKVValue("someKey").getValue().getValue().getBytes());

Hi,

We have the following problem with the client: https://github.com/Ecwid/consul-api/issues/42.

I also wanted to ask there to see if someone else has encountered such a problem.

Thanks,

Best,

Very awesome Consul client, wonder how you do watchers with this library?

[Vasily Vasilkov]

Hi,

We still doesn't support watches, please look at this issue - https://github.com/Ecwid/consul-api/issues/19

Hello Vasily,

Thanks for the lib. Appreciate it. I am trying to use the JAVA client API (https://github.com/Ecwid/consul-api) in one of my application. I am looking for API documentation for Java Classes in the consul-api-1.2.3.jar. For example, I am using ConsulClient class and looking for documentation on that. I have searched but can't find the docs for it. Would you be kind enough to help me get to the docs please?
Thanks
