SEEK's Job Ad Posting API Client

What It Is

1. A .NET version of SEEK's Job Ad Posting API Client which can be installed via NuGet.
2. It comprises of the following three projects:
   1. SEEK.AdPostingApi.Client - Source code of the API client
   2. SEEK.AdPostingApi.SampleConsumer - Example code using the API client to make requests to the Job Ad Posting API
   3. SEEK.AdPostingApi.Client.Tests - Contract (PACT) tests between the API client and the Job Ad Posting API.

What It Does

1. Exchanges the OAuth 2.0 credentials (client key and client secret) for an OAuth 2.0 access token.
2. Using the OAuth 2.0 access token:
   1. Retrieves the API links from the Job Ad Posting API.
   2. Depending on the operation (create, update, retrieve or expire):
      1. Builds the appropriate API link for the operation.
      2. Makes the appropriate request to the API.

Resources

1. Job Ad Posting API Documentation
2. NuGet Package
3. Release Notes
4. Contract (PACT) Between the API Client and the Job Ad Posting API

Usage

Install the API Client

Via NuGet with Install-Package SEEK.AdPostingApi.Client

Initializing the API Client

To initialize a client, the following values are needed:

• Client Key [Required]: the client key for getting an OAuth 2 access token
• Client Secret [Required]: the client secret for getting an OAuth 2 access token
• Environment [Optional]: the environment to which your consumer will integrate with, either "Integration" or "Production" can be supplied. Without supplying anything, "Production" will be used by default.
• AdPostingApiBaseUrl [Optional]: the URL of the Job Ad Posting API. Without supplying anything, the Production URL will be used by default.

Example Code: Construct an API Client to Create a Job Advertisement

IAdPostingApiClient postingClient = new AdPostingApiClient("<client id>", "<client secret>", Environment.Integration);

var ad = new Advertisement
{
    CreationId = "Sample Consumer 20151001 114732 1234567",
    ThirdParties = new ThirdParties { AdvertiserId = "Advertiser Id" },
    JobTitle = "A Job Title",
    JobSummary = "Job summary of the job ad",
    AdvertisementDetails = "Experience Required",
    AdvertisementType = AdvertisementType.Classic,
    WorkType = WorkType.Casual,
    Salary = new Salary
    {
        Type = SalaryType.HourlyRate,
        Minimum = 20,
        Maximum = 24
    },
    Location = new Location
    {
        Id = "Melbourne",
        AreaId = "MelbourneNorthernSuburbs"
    },
    SubclassificationId = "AerospaceEngineering"
};

AdvertisementResource advertisement = await postingClient.CreateAdvertisementAsync(ad);

Example Code: Custom Request Logging

This client supports specifying a custom DelegatingHandler for logging or processing requests/responses before they're sent. The custom delegating handlers will:

1. Be last in the request pipeline before sending the request; and
2. Will have the InnerHandler automatically set by the AdPostingApiClient

For example, a custom LoggingDelegatingHandler can be specified:

public class LoggingDelegatingHandler : DelegatingHandler
{
    protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        Log.Verbose("Making request to {RequestUri}", request.RequestUri);
        return await base.SendAsync(request, cancellationToken);
    }
}

using (var client = new AdPostingApiClient("<client id>", "<client secret>", Environment.Integration, new LoggingDelegateHandler()))
{
    // Use the client as per normal
}

Building

The build scripts are written in GNU Make.

Prerequisites

1. Dotnet core 2.1 LTS SDK.
2. GNU Make to run the build locally.
3. CS-Script for generating PACT markdown files. If ".Net Core 2.1 Global Tool" does not work, use the OS-specific install instructions.

Steps

Run make from the root folder to get help on targets.

Example targets:

• make to show help
• make test to build and run tests locally

Notes

• The latest PACTs in /pact should be committed and pushed, this includes the documentation generated with the pact-markdown target

Building (Powershell / Cake)

The build scripts are written in Cake (C#), and will automatically pull down the required .NET Core SDK.

Prerequisites

1. Powershell v4 or later
2. CS-Script for generating PACT markdown files. If ".Net Core 2.1 Global Tool" does not work, use the OS-specific install instructions.

Steps

Run the builds from the build folder.

Some example targets:

• .\build.ps1 -Target Help to list help
• .\build.ps1 -Target Test to build and run all tests
• .\build.ps1 -Target Test -Configuration Debug to build and run all tests in debug mode
• .\build.ps1 -Target NuGet to build a NuGet package in /out
• .\build.ps1 -Target PactMarkdown to generate Markdown of the PACTs in /pact, this is required if they've changed
• .\build.ps1 -Target UploadPact to build, run all tests, and upload the PACTs to the broker
  • The broker can be specified with environment variables: PACT_BROKER_URL, PACT_BROKER_USERNAME (optional), and PACT_BROKER_PASSWORD (optional)

Notes

• The latest PACTs should be committed to /pact, this includes the documentation generated with the PactMarkdown target
