EventList

public BackendReturnObject EventList();
public BackendReturnObject EventList(int limit);
public BackendReturnObject EventList(int limit, string offset);

Parameters

ValueTypeDescription
limitint(Optional) Number of events to be loaded
offsetstring(Optional) Starting point of the events to be loaded
It can be obtained via BackendReturnObject.LastEvaluatedKeyString().

Description

This is a function for receiving the events registered in BACKND Console.

  • When the user has a country code and an event of that country is registered in the console → The event's title and content for that country will be returned.
  • If the user's country code is not present, or if an event is not registered for the country in the console → Returns the default title and content.

Example

Synchronous

//Calls 10 events lists
BackendReturnObject bro = Backend.Event.EventList(10);

if(bro.IsSuccess()) {
//Event 10 after calling 10 events
string offset = bro.LastEvaluatedKeyString();
if(!string.IsNullOrEmpty(offset)) {
// 2. Loads 3 events after loading 2 events
Backend.Event.EventList(3, offset);
}
}

Asynchronous

Backend.Event.EventList(2, (callback) => {
// Post-process
if(callback.IsSuccess()) {
string offset = callback.LastEvaluatedKeyString();
if(!string.IsNullOrEmpty(offset)) {
// 2. Loads 3 events after loading 2 events
Backend.Event.EventList(3, offset, (callback2) => {
// Post-process
});
}
}
});

SendQueue

SendQueue.Enqueue(Backend.Event.EventList, 2, (callback) => {
// Post-process
if(callback.IsSuccess()) {
string offset = callback.LastEvaluatedKeyString();
if(!string.IsNullOrEmpty(offset)) {
// 2. Loads 3 events after loading 2 events
SendQueue.Enqueue(Backend.Event.EventList, 3, offset, (callback2) => {
// Post-process
});
}
}
});

Return cases

Success cases

When loaded successfully
statusCode : 200

returnValue : refer to GetReturnValuetoJSON

When the number of events is 0
statusCode : 200

returnValue : { "rows":[] }

GetReturnValuetoJSON

In the case of success, the information about the registered events is displayed.

How to look up an image attached to the event

If you registered a content image and pop-up image when registering the event, you can check the address where the images are stored using the contentImageKey and popUpImageKey values, respectively, in the above GetReturnValuetoJSON() value.

To look up the image, add its image key to the image key returned to http://upload-console.thebackend.io and make a request to the address shown below.

http://upload-console.thebackend.io/upload/2147483648/event/2018-12-27T02:46:57.391Z312652213.jpg
Caution for iOS
  • iOS blocks http access as a default setting according to its security policy. If you wish to load an image attached to an announcement/event from an iOS device, allow all http or add certain domains as exceptions as shown below.

Open Info.lplist after building a project > In 'Key,' find or create the value of App Transport Security Settings Key.

Case 1. When allowing all Http access:

Go to App Transport Security Settings and change Allow Arbitrary Loads to YES.

Case 2. When allowing access only from certain domains

  • Go to App Transport Security Settings and change Allow Arbitrary Loads to NO.
  • In the options of App Transport Security Settings, create Exception Domains and add upload-console.thebackend as its subcategory.
