ReadMail(Admin, Rank, Coupon)

public BackndReturnObject ReadMail(MailType mailType, string postIndate);

caution

The inDate needed for claiming mail can be loaded with the mail loading method(Mail.GetMailList).
The mail may not be claimed even with a correct inDate if the mail is not loaded.
Only mail added to the mail list through the mail list loading can be claimed.

Parameters

ValueTypeDescription
mailTypeMailTypeType of the single mail to claim
postIndatestringinDate of the mail from which items were received

MailType

ValueDescription
AdminAdmin mail sent from BACKND Console
RankRanking mail sent automatically after ranking settlement
CouponCoupon mail sent after using a coupon with the page created in Web Coupon Settings in BACKND Console
UserUser mail sent using each user's data

Description

Claims one piece of mail using its indate.
You may use the same logic for claiming admin, ranking, and coupon mail, as they all have the same return values when claimed. Different return values are provided for user mail.

  • The data types "S", "L", and "M" in the return values of the previous mail function(Backnd.Player.Post) was removed.
  • Even if indate exists, you cannot claim the mail if it is a different MailType.
  • The mail is removed from the list after being claimed. You can check which items are claimed using returnValue.
  • Users who have claimed the mail are displayed in the mail details in the console's Mail Management along with the date received.(not the case for coupon and user mail)
  • You cannot claim expired mail.
  • Information of the received item will not be inserted/modified in the user's DB automatically, so you must update it manually to the recipient's game information in the client.

Example

Synchronous

MailType type = MailType.Admin;

//Load mail list
BackndReturnObject bro = Backnd.Mail.GetMailList(type, limit);
BACKND.LitJson.JsonData json = bro.GetReturnValuetoJSON()["postItems"];

//Get the inDate of the 0th mail in the mail list
string recentPostIndate = json[0]["inDate"].ToString();

// Claim mail with the same MailType
Backnd.Mail.ReadMail(type, recentPostIndate);

Asynchronous

//Mail type
MailType type = MailType.Admin;

//Load mail list
Backnd.Mail.GetMailList(type, limit, callback => {
BACKND.LitJson.JsonData json = callback.GetReturnValuetoJSON()["postItems"];

//Get the inDate of the 0th mail in the mail list
string recentPostIndate = json[0]["inDate"].ToString();

// Claim mail
Backnd.Mail.ReadMail(type, recentPostIndate, callback2 => {
if(callback2.IsSuccess()) {
Debug.Log("Successfully claimed the mail.");
}
});
});

{
"postItems": [
{
"item": {
"chartFileName": "chartExample.xlsx",
"itemID": "i101",
"itemName": "Item111",
"hpPower": "1",
"aabab": "1"
},
"itemCount": 1,
"chartName": "DataTable"
}
]
}

Mail with 2 or more types of item

{
"postItems": [
{
"item": {
"chartFileName": "chartExample.xlsx",
"itemID": "i101",
"itemName": "Item111",
"hpPower": "1",
"aabab": "1"
},
"itemCount": 1,
"chartName": "DataTable"
},
{
"item": {

"itemID": "sword1",
"itemName": "Longsword",
"atk": "17",
"money": "350"
