Generating hot signing links using python had been a roadblock for our bot development.

### After a bit of trial by error, found the issue and the solution.

     Long story short, it was a encoding issue corrected by enclosing the required_auths and required_posting_auths arrays in doublequotes as follows:

```
...
		"required_auths": "[\"anthonyadavisii\"]",
		"required_posting_auths": "[]",
...
```

     The latter didn't matter so much as it was an empy array but the former had double quotes which were being encoded as single quotations(%27) as a result. This led to an "Invalid cast from string_type to Array" error when attempting the link.

*Anyways, glad this was figured out so we can move forward with the next phases of development.*

```

- Usage:

Import script as module.

I plan on refining this so it may be run as a script in addition to interactively. Feel free to fork and suit to your purpose. I will be using it as part of the abuse reporting functionality for Hive Downvote Rewards project (@hive-dr) formerly @steemflagrewards.
