Maintained Fork of Camunda.Api.Client

After Jan Lucansky stopped maintaining the orginal version we started maintaining our own fork. It is a drop-in-replacement for the original version. Just use Komsa.Camunda.Api.Client nuget package instead of Camunda.Api.Client.

Basic Authentication
HttpClient httpClient = new HttpClient();
httpClient.BaseAddress = new Uri("http://localhost:8080/engine-rest");
httpClient.DefaultRequestHeaders.Add("Authorization", "Basic ZGVtbzpkZW1v");
CamundaClient camunda = CamundaClient.Create(httpClient);
Filter external tasks
// build query
var externalTaskQuery = new ExternalTaskQuery() { Active = true, TopicName = "MyTask" };

// add some sorting
    .Sort(ExternalTaskSorting.TaskPriority, SortOrder.Descending)

// request external tasks according to query
List<ExternalTaskInfo> tasks = await camunda.ExternalTasks.Query(externalTaskQuery).List();
Get all external tasks
// get all external tasks without specifying query
List<ExternalTaskInfo> allTasks = await camunda.ExternalTasks.Query().List();
Set process variable
VariableResource vars = camunda.ProcessInstances["0ea218e8-9cfa-11e6-90a6-ac87a31e24fd"].Variables;

// set integer variable
await vars.Set("Var1", VariableValue.FromObject(123));

// set content of binary variable from file
await vars.SetBinary("DocVar", new BinaryDataContent(File.OpenRead("document.doc")), BinaryVariableType.Bytes);
Load typed variables
var executionId = "290a7fa2-8bc9-11e6-ab5b-ac87a31e24fd";
// load all variables of specified execution
Dictionary<string, VariableValue> allVariables = await camunda.Executions[executionId]

// obtain strongly typed variable with name Var1
int myVar1 = allVariables["Var1"].GetValue<int>();
Save content of variable to file
HttpContent fileContent = await camunda.Executions[executionId]

using (fileContent)
    using (var outStream = File.OpenWrite("file1.doc"))
        (await fileContent.ReadAsStreamAsync()).CopyTo(outStream);
Message correlation
var msg = new CorrelationMessage() { All = true, MessageName = "TestMsg" };

Conditional query
// get all jobs owned by Process_1 with DueDate in the future
var jobQuery = new JobQuery() { ProcessDefinitionKey = "Process_1" };
jobQuery.DueDates.Add(new ConditionQueryParameter() 
    Operator = ConditionOperator.GreaterThan, Value = DateTime.Now

var jobs = await camunda.Jobs.Query(jobQuery).List();
