kandi X-RAY | captain Summary

captain is a Java library typically used in Architecture applications. captain has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

Captain is yet another service discovery implementation based on redis. Captain sacrifices a little high availability for simplicity and performance. In most cases, we don't have tens of thousands of machines, the possibility of machine crashing is very low, high availability is not so abviously important. But the market only provides zookeeper/etcd/consul, they are complex, at least much complexer compared with captain. 中文文档.

            Post to PHP script after successful paypal payment
            Asked 2021-Jun-05 at 03:07

            I have an html form for registering for a club. I then have a php script that I want to have called that will send an email to me with the registration info. What I need to have happen is have the PHP script called once I get a successful payment through paypal. Under sandbox I am successfully hitting the 'onApprove' callback. I just wonder how I call the PHP file and post the data from the form. Any help would be appreciated. Or if there's a better way to do it, please let me know.

            In order to make a call to the PHP file after a successful payment, you could easily do a call to the file using jQuery's .post() method.

            Below is an example of what the post call would look in your JavaScript code. Using this will successfully call your PHP file once the JavaScript is invoked and you can use the data payload to return the data from the PHP file back to the original page.

            Following my comment above

            You might have an easier time of it if you split into lines first, and then split into words, because I expect the abbreviated character names will always be at the start of a line? Also, I notice the line is indented a couple spaces when a new character starts speaking. That could be another thing to look for.

            ANSWER

            Answered 2021-May-02 at 12:57

            You defined the postgres superuser as POSTGRES_USER: my_app (see the readme on dockerhub for details), but try to login with username postgres (psql -U **postgres**), which doese not exist. If we switch it to my_app, it should work. Same goes for the health check.

            Alternatively, we could set the POSTGRES_USER to, e.g., postgres or root (or whatever we want) and provide initialization scripts to the container's directory /docker-entrypoint-initdb.d/. All *.sql-scripts in this folder will be executed on database startup. A common approach is to mount a host-directory, containing all scripts (e.g. creation of a new role, creation of a new database, and giving the new role ownership to this database) to this container-directory. An example can be found in this bitbucket repository of mine. We can just focus on the postgres container and the postgres directory, since those are the important parts.
