Parameters:

requestTimeout - request timeout in milliseconds

connectTimeout - connect timeout in milliseconds

HttpClient

public HttpClient(int requestTimeout,
                  int connectTimeout,
                  RetryOptions retryOpts)

Constructs HttpClient class instance

Parameters:

requestTimeout - request timeout in milliseconds

connectTimeout - connect timeout in milliseconds

retryOpts - retrying options

Method Detail

request

public CompletableFuture<String> request(HttpRequestOptions options)

Performs a request. Completable future response errors are returned as ApiError or subclasses. Also see makeRequest(HttpRequestOptions) for more information about the result completion cases.

Parameters:

options - request options

Returns:

completable future with request results

request

public CompletableFuture<String> request(HttpRequestOptions options,
                                         int retryCounter)

Performs a request. Completable future response errors are returned as ApiError or subclasses. Also see makeRequest(HttpRequestOptions) for more information about the result completion cases.

Parameters:

options - request options

retryCounter - retry counter

Returns:

completable future with request results

requestJson

public <T> CompletableFuture<T> requestJson(HttpRequestOptions options,
                                            Class<T> valueType)

Does the same as request(HttpRequestOptions) but automatically converts response into json. If there is a json parsing error, completes exceptionally with JsonProcessingException.

Type Parameters:

T - any DTO object that can be converted from json

Parameters:

options - request options

valueType - class into which the response will be transformed

Returns:

completable future with request results as json

requestJson

public <T> CompletableFuture<T> requestJson(HttpRequestOptions options,
                                            Class<T> valueType,
                                            int retryCounter)

Does the same as request(HttpRequestOptions) but automatically converts response into json. If there is a json parsing error, completes exceptionally with JsonProcessingException.

Type Parameters:

T - any DTO object that can be converted from json

Parameters:

options - request options

valueType - class into which the response will be transformed

retryCounter - retry counter

Returns:

completable future with request results as json

makeCheckedRequest

protected CompletableFuture<kong.unirest.HttpResponse<String>> makeCheckedRequest(HttpRequestOptions options,
                                                                                  int retryCounter)

Performs a request. Completable future response errors are returned as ApiError or subclasses. Also see makeRequest(HttpRequestOptions) for more information about the result completion cases.

Parameters:

options - request options

retryCounter - retry counter

Returns:

completable future with request response

makeRequest

protected CompletableFuture<kong.unirest.HttpResponse<String>> makeRequest(HttpRequestOptions options)

Makes request and returns HTTP response. If request fails, completable future completes exceptionally with UnirestException.

Parameters:

options - request options

Returns:

completable future resolving with http response object
