How can I use Metamask RPC API to build an Ethereum miner? - ethereum

I am tring to build an Ethereum miner using Metamask RPC. I saw eth_getWork and eth_submitWork methods, but I can't use them because I need to connect as a miner first. How can I do that?
Thanks for your help!

You need to send login request, example:
{"id": 1,"jsonrpc": "2.0","method": "eth_submitLogin","params": ["0xblablalba"]}

Is there a way for parsing the IAM users credentials inside a http body for the elasticsearch service?

I'm setting up some authentication methods in my elasticsearch endpoint in AWS. So, I'm trying to make HTTP requests to this endpoint parsing inside this body the IAM credentials but I have no idea how I can do it.
Maybe adding a field in the content body or header before the query or something like.
{
"IAM-ARN":"SOMERANDOMID",
"IAM-PASS":"SOMERANDOMPASS"
}
I would be so thankful for finding this solution.
Thank you!
You can access using IAM credentials by signing the requests as if you were making a call to AWS api.
Here's an exapmple:
https://docs.aws.amazon.com/AmazonS3/latest/dev/RESTAuthentication.html#ConstructingTheAuthenticationHeader
Or you could just use an sdk. What language are you using?

About Twitter's REST API 1.1 Bad Authentication data Code : 215

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=20.9533951,75.9364752&radius=500&types=food&key=put_your_key_here
This is the URL of google maps api. Which returns json data if we pass the key at the last. and hit that url from our browser directly.
So is there anything like that in twitter as well? By which we can pass our consumer key or something like that at the end of link like this https://api.twitter.com/1.1/trends/available.json
Because without any tokens if we hit this URL then its giving error : Bad Authentication data Code : 215
Please help me. i am finding this from very long and have no luck.
Please Thank You So Much.
The short answer is no.
The long answer is that all requests to the Twitter REST API need to be authenticated using OAUTH. You need to follow the OAUTH process and use the tokens as described starting here.
&oauth_consumer_key= your consumer key
&oauth_nonce=nonce
&oauth_signature_method=HMACSHA1
&oauth_timestamp=1505894968
&oauth_token=token
&oauth_version=1.0
&oauth_signature=signature
You have to send these header with your request then it will work fine

Assistance required to connect to Foursquare via TIBCO BW using REST / JSON API - 1.1

We have an assignment to check the compatibility of Quick connect project for Foursquare against the REST/JSON 1.1.
When I am testing the process, while invoking Rest API for query Check-in, the process is throwing an error – “OAuth token invalid or revoked”. Can you kindly help to fix this issue.
Access_token for this was generated by registering a sample app with Foursuare.com, having www.google.com as welcome page and redirect URL. Please let me know if this is causing the issue.
Also, let me know is there is any standard method to generate the access_token for this.
Thanks in advance.
Regards,
Shree.
It sounds like you're not following Foursquare's instructions on connecting properly, or need to reconnect to get a new access_token. Keep in mind that the access_token isn't the code that comes back in the redirect, the code needs to be used to exchange for the access_token.

JUNIT Tests for OSB services

Can we have Junit Test cases for testing Proxy, Business Services in Oracle Service Bus?
If yes can someone give me some pointers to the same.
this can be done by creating test suites to put and get messages from the queue and having your proxy do the transformation. The transformed output can then be compared with the expected out by simple string comparison.
JUnits can also be written for any type of proxy not only queue based proxies.
If your Testing technology has the ability to test Web Services or RESTful Services, then it can be applied to OSB Services.
Remember what Interface you define for the OSB Service is how you invoke it.
So if it is a REST-based interface then you will make REST Calls, if it has a SOAP-Based interface then you will Make SOAP Calls i.e. SOAP Request Messages.
In terms of Assertions, same applies just like Web and REST Service:
Response Status Code
Response Message Body (usually XML for SOAP and JSON for REST)
