Vika Java SDK
Vikadata™ Java API (vika.java) provides a full featured and easy to consume Java
library for working with vikadata via the Vikadata OpenAPI.
Java 8+ is required to use sdk. not support Java 8 below

}vika java sdk is quite simple to use, you don't need to set api url, all you need is the
Personal Api Key from your vika account settings page. Once you have that info it is as
simple as:
First, you need to set api credential which belong your personal api key.
ApiCredential credential = new ApiCredential("Your API Key");Then, Init client instance
VikaApiClient vikaApiClient = new VikaApiClient(credential);By default, the API client has been added for setting connect and read timeouts, you can also change:
// Set the connect timeout to 8 second and the read timeout to 9 seconds
VikaApiClient vikaApiClient = new VikaApiClient(credential)
.withRequestTimeout(80000)
.withReadTimeout(90000);As private deployment user, you can also change host url
VikaApiClient vikaApiClient = new VikaApiClient("http://ip:port", credential);Most simple usage for query record quickly
// Get 10 records on first page
List<Record> records = vikaApiClient.getRecordApi().getRecords("datasheetId", 1, 10);API client provides an easy way to use paging mechanism to page through lists of results from the Open API. Below code are a couple of examples on how to use the Pager:
// Get a Pager instance that will page through the records with 100 record per page
Pager<Record> pager = vikaApiClient.getRecordApi().getRecords("datasheet_id", 100);
// Iterate through the pages and print out the per record detail
while (pager.hasNext()) {
for (Record record : pager.next()) {
System.out.println(record.getRecordId() + " -: " + record.getFields());
}
}you can also fetch all the items as a single list using a Pager instance:
// Get a Pager instance so we can load all the records into a single list, 100 record at a time:
Pager<Record> pager = vikaApiClient.getRecordApi().getRecords("datasheet_id", 100);
List<Record> records = pager.all();Java 8 Stream Support
also provide method that returns a Java 8 Stream.
// Pager as stream,support forEach、Group、Filter operation
Stream<Record> records = vikaApiClient.getRecordApi().getRecordsAsStream("datasheet_id");
// ex: extract record id to a list
records.map(Record::getRecordId).collect(Collectors.toList());Advance Query
// build query condition
ApiQueryParam queryParam = new ApiQueryParam(1, 50)
.withView("viewId")
.withFields(Arrays.asList("fieldName"))
.withRecordIds(Arrays.asList("recordId"))
.withSort("fieldName", Order.DESC).withSort("fieldName", Order.ASC)
.withFilter("{fieldName}>1");
// query return pager result
Pager<Record> pager = vikaApiClient.getRecordApi().getRecords("datasheet_id", queryParam);Class RecordMap is a key-value structure like Map<String, Object>, all thing you do is converting json to map, you can use convert util from sdk provide which is named JacksonConverter, you also can use jackson api build json structure data, more detail please reference unit test.
you can add record through two difference way, id or name, default is name fieldKey.
using default fieldKey name example:
// Build Record Map by jackson api
ObjectNode fieldMap = JsonNodeFactory.instance.objectNode()
// simple data
.put("fieldName", "string")
.put("number", 1234);
// sub tree node
.set("city", JsonNodeFactory.instance.arrayNode().add("NewYork").add("Bejing"));
// put record map into fields key
ObjectNode fields = JsonNodeFactory.instance.objectNode().set("fields", fieldMap);
// only one record, warp record into array node
ArrayNode arrayNode = JsonNodeFactory.instance.arrayNode().add(fields);
// convert json to Map List
List<RecordMap> recordMaps = JacksonConverter.unmarshalToList(RecordMap.class, arrayNode);
// create record request
CreateRecordRequest recordRequest = new CreateRecordRequest()
.withRecords(recordMaps);
// ok
List<Record> newRecords = vikaApiClient.getRecordApi().addRecords("datasheet_id", recordRequest);using fieldKey id example:
// Build Record Map by jackson api
ObjectNode fieldMap = JsonNodeFactory.instance.objectNode()
// simple data
.put("fld_id", "string")
.put("fld_id", 1234);
// sub tree node
.set("fld_id", JsonNodeFactory.instance.arrayNode().add("NewYork").add("Bejing"));
// put record map into fields key
ObjectNode fields = JsonNodeFactory.instance.objectNode().set("fields", fieldMap);
// only one record, warp record into array node
ArrayNode arrayNode = JsonNodeFactory.instance.arrayNode().add(fields);
// convert json to Map List
List<RecordMap> recordMaps = JacksonConverter.unmarshalToList(RecordMap.class, arrayNode);
// create record request
CreateRecordRequest recordRequest = new CreateRecordRequest()
.withRecords(recordMaps)
.withFieldKey(FieldKey.ID);
// ok
List<Record> newRecords = vikaApiClient.getRecordApi().addRecords("datasheet_id", recordRequest);update record also provide two difference way to modifying data, using fieldKey id or name, default is name fieldKey.
using default fieldKey name example:
// Build update record model
UpdateRecord record = new UpdateRecord()
// row record id from query result or add record result
.withRecordId("recXXXXX")
// single-text type field cell
.withField("SingleText", "ABC")
// single-select type field cell,
// it can be set null or empty array if you want to clear field value: withField("Options", null)
.withField("Options", Arrays.asList("LL", "NN"));
// new Request model
UpdateRecordRequest updateRecordRequest = new UpdateRecordRequest()
.withRecords(Collections.singletonList(record));
// request send
List<Record> updateRecords = vikaApiClient.getRecordApi().updateRecords("datasheet_id", updateRecordRequest);using fieldKey id example:
// Build update record model
UpdateRecord record = new UpdateRecord()
// row record id from query result or add record result
.withRecordId("recXXXXX")
// single-text type field cell
.withField("fld_id", "ABC")
// single-select type field cell,
// it can be set null or empty array if you want to clear field value: withField("Options", null)
.withField("fld_id", Arrays.asList("LL", "NN"));
// new Request model
UpdateRecordRequest updateRecordRequest = new UpdateRecordRequest()
.withRecords(Collections.singletonList(record))
.withFieldKey(FieldKey.ID);
// request send
List<Record> updateRecords = vikaApiClient.getRecordApi().updateRecords("datasheet_id", updateRecordRequest);// DELETE one record only
vikaApiClient.getRecordApi().deleteRecord("datasheet_id", "recXXXXXX");
// DELETE many record
vikaApiClient.getRecordApi().deleteRecords("datasheet_id", Arrays.asList("recXXXXXX", "recXXXXXX"));
// Delete all records, may be slowly work if sheet have large records
vikaApiClient.getRecordApi().deleteAllRecords("datasheet_id");sdk provide several way to upload attachment, You can choose the way to upload anything that suits you
// classPath resource on src/main/resource/test.txt
ResourceLoader classPathResource = new ClassPathResourceLoader("test.txt");
Attachment attachment = vikaApiClient.getAttachmentApi().upload("datasheet_id", classPathResource);
// or url resource from web
ResourceLoader urlResource = new UrlResourceLoader(UrlUtil.url("https://test.com/image.png"))
Attachment attachment = vikaApiClient.getAttachmentApi().upload("datasheet_id", urlResource);
// or file resource
File file = new File("/Users/Document/test.txt");
Attachment attachment = vikaApiClient.getAttachmentApi().upload("datasheet_id", new FileResourceLoader(file));
// or upload file type directly
File file = new File("/Users/Document/test.txt");
Attachment attachment = vikaApiClient.getAttachmentApi().upload("datasheet_id", file);You can create field by sdk. Firstly, we need to build the property required by the field. Secondly, Using CreateFieldRequestBuilder to creating a CreateFieldRequest object. Finally, submitting the request to the specified space and the specified datasheet. If creating the field successfully, we can get the new field's id and name.
more detail about field type and property of field see official API manual#create-field
create single text field example:
// build the SingleText field's property
SingleTextFieldProperty singleTextFieldProperty = new SingleTextFieldProperty();
singleTextFieldProperty.setDefaultValue("defaultValue");
// create a CreateFieldRequest Object
CreateFieldRequest<SingleTextFieldProperty> createFieldRequest = CreateFieldRequestBuilder
.create()
.ofType(FieldTypeEnum.SingleText)
.withName("singleText")
.withProperty(singleTextFieldProperty)
.build();
// request to create a field
CreateFieldResponse response = vikaApiClient.getFieldApi().addField("space_id", "datasheet_id", createFieldRequest);create text field example:
// if field don't require property, we can skip the process that build the property
CreateFieldRequest<EmptyProperty> createFieldRequest = CreateFieldRequestBuilder
.create()
.ofType(FieldTypeEnum.Text)
.withName("text")
.withoutProperty()
.build();
// request to create a field
CreateFieldResponse createFieldRequest = vikaApiClient.getFieldApi().addField("space_id", "datasheet_id", createFieldRequest);// we can use field_id to detele field
vikaApiClient.getFieldApi().deleteField("space_id", "datasheet_id", "field_id");You can create a datasheet with the help of a CreateDatasheetRequest Object. If creating the datasheet successfully, we can get the new datasheet's id, name and the fields' id, name.
more detail see official API munual#create-datasheet
// create a CreateDatasheetRequest Object
CreateDatasheetRequest createDatasheetRequest = new CreateDatasheetRequest();
// datasheet's name is required.
request.setName("datasheet");
// add description to datasheet
request.setDescription("description");
// specify the folder where the datasheet is stored
request.setFolderId("fold_id");
// specify the datasheet's previous node
request.setPreNodeId("pre_node_id");
// datasheet's initial fields
SingleTextFieldProperty property = new SingleTextFieldProperty();
property.setDefaultValue("defaultValue");
// a SingleText field
CreateFieldRequest<SingleTextFieldProperty> singleSelectField = CreateFieldRequestBuilder
.create()
.ofType(FieldTypeEnum.SingleText)
.withName("singleSelect")
.withProperty(property)
.build();
// a Text field
CreateFieldRequest<EmptyProperty> textField = CreateFieldRequestBuilder
.create()
.ofType(FieldTypeEnum.Text)
.withName("text")
.withoutProperty()
.build();
List<CreateFieldRequest<?>> fields = new ArrayList<>();
fields.add(singleSelectField);
fields.add(textField);
request.setFields(fields);
// request to create a datasheet
CreateDatasheetResponse response = vikaApiClient.getDatasheetApi().addDatasheet("space_id", createDatasheetRequest);Vika java sdk project uses GitHub's integrated issue tracking system to record bugs and feature requests. If you want to raise an issue, please follow the recommendations below:
