CS 340 Milestone Two Guidelines and Rubric Overview: For this assignment, you will implement a basic RESTful web service using either Python or Java. You will use the language-specific web services framework to implement the RESTful service. You will later build upon this simple RESTful service implementation for your final project. Make sure you are using the same programming language you chose in Module Four, as this assignment will build on the work you completed for Milestone One. Reminders • • Make sure you complete either the Java or the Python REST service tutorial in your Codio terminal before you start this assignment. Type all Python code into your Codio terminal manually, especially when running the Python example code below. Python is space-sensitive and does not copy into the Codio terminal well. Prior to completing the prompt for this assignment, run the following code in your chosen language. Create a basic web service using the RESTful design pattern to implement the following URI example: http://localhost/currentTime The above URI should return the current server system time in the following JSON format text: { date : MM-DD-YYYY , time : HH:MM:SS } Example Python Code #!/usr/bin/python import json from bson import json_util import bottle from bottle import route, run, request, abort # set up URI paths for REST service @route('/currentTime', method='GET') def get_currentTime(): dateString=datetime.datetime.now().strftime("%Y-%m-%d") timeString=datetime.datetime.now().strftime("%H:%M:%S") string="{\"date\":"+dateString+",\"time\":"+timeString+"}" return json.loads(json.dumps(string, indent=4, default=json_util.default)) if __name__ == '__main__': #app.run(debug=True) run(host='localhost', port=8080) Example Java Code Using Spring.io Framework Application.java: package hello; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } } GreetingController.java package hello; import java.util.concurrent.atomic.AtomicLong; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; import java.util.Date; import java.text.SimpleDateFormat; import java.util.Calendar; @RestController public class GreetingController { private static final String template = "Hello, %s!"; private final AtomicLong counter = new AtomicLong(); } @RequestMapping("/greeting") public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) { return new Greeting(counter.incrementAndGet(), String.format(template, name)); } @RequestMapping("/currentTime") public Greeting greeting() { SimpleDateFormat df = new SimpleDateFormat("yyyyMMdd HH:mm"); String sdt = df.format(new Date(System.currentTimeMillis())); return new Greeting(counter.incrementAndGet(), sdt); } Greeting.java package hello; public class Greeting { private final long id; private final String content; public Greeting(long id, String content) { this.id = id; this.content = content; } public long getId() { return id; } public String getContent() { return content; } } Prompt: After reviewing the module resources, complete the following tasks in Codio: 1. Create a basic web service using the RESTful design pattern to implement the following URIs: a. http://localhost/hello?name=”world” The above URI should return the following JSON-format text: { hello: “world” } b. HTTP POST the JSON data: {string1:”hello”, string2:”world”} to http://localhost/strings The above URI should return the following JSON-format text: { first: “hello”, second: “world” } Provide a text file (either .java or .py) of your code and screenshots of execution as evidence. You will use the curl utility at the Codio command line to execute the URI. See the examples below. HTTP Action Operation Curl Example Possible HTTP Response Codes GET Read curl http://localhost:8080/hello?name=”world” 200 OK, 404 Not Found POST Create curl -H "Content-Type: application/json" -X POST -d '{"string1":"hello","string2":"world"}' http://localhost:8080/strings 200 OK, 404 Not Found 2. Using the RESTful web service you created in Step 1, add URI paths to the RESTful service for each of your CRUD functions completed in Milestone One. Your URI paths should be able to handle the following curl client interactions: "Add the following document to the collection:" curl -H "Content-Type: application/json" -X POST -d '{"id" : "10011-2017-TEST","certificate_number" : 9278833,"business_name" : “ACME TEST INC.","date" : "Feb 20 2017","result" : "No Violation Issued","sector" : "Test Retail Dealer - 101"}' http://localhost:8080/create "Return the document found with the given business_name" curl http://localhost:8080/read?business_name="ACME TEST INC." "Update the result value for the document with the given id string" curl http://localhost:8080/update?id="10011-2017-TEST"&result="Violation Issued" "Delete the document with the given id string" curl http://localhost:8080/delete?id="10011-2017-TEST" Provide a text file (either .java or .py) of your code. Specifically, the following must be addressed in your submission: ● RESTful Web Service Using Either Python or Java Programming Language: Use your code submission and screenshots to demonstrate web service interactions. Rubric Guidelines for Submission: You must submit two files for this assignment: • • A Microsoft Word document (or equivalent) with double spacing, 12-point Times New Roman font, one-inch margins, and the appropriate screenshots A text file (either .java or .py) of your code Critical Elements Hello World GET Proficient (100%) Creates RESTful web service and implements GET URI Hello World String POST Creates RESTful web service and implements POST URI RESTful Service for Create Creates RESTful web service and adds URI path for create function Needs Improvement (75%) Creates RESTful web service and implements GET URI, but result lacks accuracy or appropriate functionality Creates RESTful web service and implements POST URI, but result lacks accuracy or appropriate functionality Creates RESTful web service and adds URI path for create function, but result lacks accuracy or appropriate functionality Not Evident (0%) Does not create RESTful web service or implement GET URI Value 10 Does not create RESTful web service or implement POST URI 10 Does not create RESTful web service or add URI path for create functionality 20 RESTful Service for Read Creates RESTful web service and adds URI path for read function RESTful Service for Update Creates RESTful web service and adds URI path for update function RESTful Service for Delete Creates RESTful web service and adds URI path for delete function Creates RESTful web service and adds URI path for read function, but result lacks accuracy or appropriate functionality Creates RESTful web service and adds URI path for update function, but result lacks accuracy or appropriate functionality Creates RESTful web service and adds URI path for delete function, but result lacks accuracy or appropriate functionality Does not create RESTful web service or add URI path for read functionality 20 Does not create RESTful web service or add URI path for update functionality 20 Does not create RESTful web service or add URI path for delete functionality 20 Total 100%
