# CSDE-cordapp-template-java
|
||||||
|
|
||||||
|
|
||||||
|
To help make the process of prototyping CorDapps on Corda 5 more straight forward we have developed the Cordapp Standard Development Environment (CSDE).
|
||||||
|
|
||||||
|
The CSDE is obtained by cloning this CSDE-Cordapp-Template-Java repository to your local machine. The CSDE provides:
|
||||||
|
|
||||||
|
- A pre-setup Cordapp Project which you can use as a starting point to develop your own prototypes.
|
||||||
|
|
||||||
|
- A base Gradle configuration which brings in the dependencies you need to write and test a Corda 5 Cordapp.
|
||||||
|
|
||||||
|
- A set of Gradle helper tasks which speed up and simplify the development and deployment process.
|
||||||
|
|
||||||
|
- Debug configuration for debugging a local Corda cluster.
|
||||||
|
|
||||||
|
- The MyFirstFlow code which forms the basis of this getting started documentation, this is located in package com.r3.developers.csdetemplate.flowexample
|
||||||
|
|
||||||
|
- A UTXO example in package com.r3.developers.csdetemplate.utxoexample packages
|
||||||
|
|
||||||
|
- Ability to configure the Members of the Local Corda Network.
|
||||||
|
|
||||||
|
To find out how to use the CSDE, please refer to the *Getting Started Using the CSDE* subsection within the *Developing Applications* section in the latest Corda 5 documentation at https://docs.r3.com/
|
||||||
|
|
||||||
|
|
||||||
|
## Chat app
|
||||||
|
We have built a simple one to one chat app to demo some functionalities of the next gen Corda platform.
|
||||||
|
|
||||||
|
In this app you can:
|
||||||
|
1. Create a new chat with a counterparty. `CreateNewChatFlow`
|
||||||
|
2. List out the chat entries you had. `ListChatsFlow`
|
||||||
|
3. Individually query out the history of one chat entry. `GetChatFlowArgs`
|
||||||
|
4. Continue chatting within the chat entry with the counterparty. `UpdateChatFlow`
|
||||||
|
|
||||||
|
### Setting up
|
||||||
|
|
||||||
|
1. We will begin our test deployment with clicking the `startCorda`. This task will load up the combined Corda workers in docker.
|
||||||
|
A successful deployment will allow you to open the REST APIs at: https://localhost:8888/api/v1/swagger#. You can test out some of the
|
||||||
|
functions to check connectivity. (GET /cpi function call should return an empty list as for now.)
|
||||||
|
2. We will now deploy the cordapp with a click of `5-vNodeSetup` task. Upon successful deployment of the CPI, the GET /cpi function call should now return the meta data of the cpi you just upload
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
### Running the chat app
|
||||||
|
|
||||||
|
In Corda 5, flows will be triggered via `POST /flow/{holdingidentityshorthash}` and flow result will need to be view at `GET /flow/{holdingidentityshorthash}/{clientrequestid}`
|
||||||
|
* holdingidentityshorthash: the id of the network participants, ie Bob, Alice, Charlie. You can view all the short hashes of the network member with another gradle task called `ListVNodes`
|
||||||
|
* clientrequestid: the id you specify in the flow requestBody when you trigger a flow.
|
||||||
|
|
||||||
|
#### Step 1: Create Chat Entry
|
||||||
|
Pick a VNode identity to initiate the chat, and get its short hash. (Let's pick Alice. Dont pick Bob because Bob is the person who we will have the chat with).
|
||||||
|
|
||||||
|
Go to `POST /flow/{holdingidentityshorthash}`, enter the identity short hash(Alice's hash) and request body:
|
||||||
|
```
|
||||||
|
{
|
||||||
|
"clientRequestId": "create-1",
|
||||||
|
"flowClassName": "com.r3.developers.csdetemplate.utxoexample.workflows.CreateNewChatFlow",
|
||||||
|
"requestBody": {
|
||||||
|
"chatName":"Chat with Bob",
|
||||||
|
"otherMember":"CN=Bob, OU=Test Dept, O=R3, L=London, C=GB",
|
||||||
|
"message": "Hello Bob"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
After trigger the create-chat flow, hop to `GET /flow/{holdingidentityshorthash}/{clientrequestid}` and enter the short hash(Alice's hash) and clientrequestid to view the flow result
|
||||||
|
|
||||||
|
#### Step 2: List the chat
|
||||||
|
In order to continue the chat, we would need the chat ID. This step will bring out all the chat entries this entity (Alice) has.
|
||||||
|
Go to `POST /flow/{holdingidentityshorthash}`, enter the identity short hash(Alice's hash) and request body:
|
||||||
|
```
|
||||||
|
{
|
||||||
|
"clientRequestId": "list-1",
|
||||||
|
"flowClassName": "com.r3.developers.csdetemplate.utxoexample.workflows.ListChatsFlow",
|
||||||
|
"requestBody": {}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
After trigger the list-chats flow, again, we need to hop to `GET /flow/{holdingidentityshorthash}/{clientrequestid}` and check the result. As the screenshot shows, in the response body,
|
||||||
|
we will see a list of chat entries, but it currently only has one entry. And we can see the id of the chat entry. Let's record that id.
|
||||||
|
|
||||||
|
|
||||||
|
#### Step 3: Continue the chat with `UpdateChatFlow`
|
||||||
|
In this step, we will continue the chat between Alice and Bob.
|
||||||
|
Goto `POST /flow/{holdingidentityshorthash}`, enter the identity short hash and request body. Note that here we can have either Alice or Bob's short hash. If you enter Alice's hash,
|
||||||
|
this message will be recorded as a message from Alice, vice versa. And the id field is the chat entry id we got from the previous step.
|
||||||
|
```
|
||||||
|
{
|
||||||
|
"clientRequestId": "update-1",
|
||||||
|
"flowClassName": "com.r3.developers.csdetemplate.utxoexample.workflows.UpdateChatFlow",
|
||||||
|
"requestBody": {
|
||||||
|
"id":" ** fill in id **",
|
||||||
|
"message": "How are you today?"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
And as for the result of this flow, go to `GET /flow/{holdingidentityshorthash}/{clientrequestid}` and enter the required fields.
|
||||||
|
|
||||||
|
#### Step 4: See the whole chat history of one chat entry
|
||||||
|
After a few back and forth of the messaging, you can view entire chat history by calling GetChatFlow.
|
||||||
|
|
||||||
|
```
|
||||||
|
{
|
||||||
|
"clientRequestId": "get-1",
|
||||||
|
"flowClassName": "com.r3.developers.csdetemplate.utxoexample.workflows.GetChatFlow",
|
||||||
|
"requestBody": {
|
||||||
|
"id":" ** fill in id **",
|
||||||
|
"numberOfRecords":"4"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
And as for the result, you need to go to the Get API again and enter the short hash and client request ID.
|
||||||
|
|
||||||
|
Thus, we have concluded a full run through of the chat app.

# Gradle start up script for POSIX generated by Gradle.
|
||||||
|
#
|
||||||
|
# Important for running:
|
||||||
|
#
|
||||||
|
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
|
||||||
|
# noncompliant, but you have some other compliant shell such as ksh or
|
||||||
|
# bash, then to run this script, type that shell name before the whole
|
||||||
|
# command line, like:
|
||||||
|
#
|
||||||
|
# ksh Gradle
|
||||||
|
#
|
||||||
|
# Busybox and similar reduced shells will NOT work, because this script
|
||||||
|
# requires all of these POSIX shell features:
|
||||||
|
# * functions;
|
||||||
|
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
|
||||||
|
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
|
||||||
|
# * compound commands having a testable exit status, especially «case»;
|
||||||
|
# * various built-in commands including «command», «set», and «ulimit».
|
||||||
|
#
|
||||||
|
# Important for patching:
|
||||||
|
#
|
||||||
|
# (2) This script targets any POSIX shell, so it avoids extensions provided
|
||||||
|
# by Bash, Ksh, etc; in particular arrays are avoided.
|
||||||
|
#
|
||||||
|
# The "traditional" practice of packing multiple parameters into a
|
||||||
|
# space-separated string is a well documented source of bugs and security
|
||||||
|
# problems, so this is (mostly) avoided, by progressively accumulating
|
||||||
|
# options in "$@", and eventually passing that to Java.
|
||||||
|
#
|
||||||
|
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
|
||||||
|
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
|
||||||
|
# see the in-line comments for details.
|
||||||
|
#
|
||||||
|
# There are tweaks for specific operating systems such as AIX, CygWin,
|
||||||
|
# Darwin, MinGW, and NonStop.
|
||||||
|
#
|
||||||
|
# (3) This script is generated from the Groovy template
|
||||||
|
# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
