Query Messages

Feature Overview

You can call findMessages to query a local message by messageID.
1. Only local messages can be queried, for example, received messages or historical messages pulled by API.
2. Audio-video group (AVChatRoom) messages cannot be queried, as they are not saved locally.
You can call searchCloudMessages to search for cloud messages(recommended).

UI Display








Find A Local Message

Note:
1. This interface queries the messages stored locally through getMessageList.
API
chat.findMessage(messageID);
Parameters
Name
Type
Description
messageID
String
Message ID
Return value
Message or null.
Examples
let message = chat.findMessage('144115217363870632-1647417469-77069006');
if (message) {
  // Read the attributes of `message`, such as `readReceiptInfo`
}

Search cloud messages

Note：
1. This feature is a value-added service, and you need to purchase the cloud search plugin.
2. This interface has a local rate limit of 2 times per second.
3. When searching for messages in [All Conversations], if the number of matching messages messageCount > 1, the interface returns an empty messageList []. You can display [${messageCount} ]related records on the UI. If you want to highlight the matching messages, please refer to [Specified Search] to highlight the returned messageList.
4. When searching for messages in [All Conversations], if the number of matching messages in a conversation = 1, then messageList is the matching message.
5. Community, topic, and live group chats do not support searching cloud messages.

Return value
Promise
Examples
let promise = chat.searchCloudMessages({
   keywordList: ['hello', 'where are you'],
});
let promise = chat.searchCloudMessages({
   keywordList: ['hello', 'where are you'],
   keywordListMatchType: 'and',
});
let promise = chat.searchCloudMessages({
   keywordList: ['hello', 'where are you'],
   senderUserIDList: ['user1', 'user2'],
});
let promise = chat.searchCloudMessages({
   keywordList: ['hello', 'where are you'],
   messageTypeList: [TencentCloudChat.TYPES.MSG_TEXT, TencentCloudChat.TYPES.MSG_CUSTOM],
});
let promise = chat.searchCloudMessages({
   keywordList: ['hello', 'where are you'],
   timePosition: Number((new Date().getTime()/1000).toFixed(0)),
   timePeriod: 24 * 60 * 60,
});
promise.then(function(imResponse) {
   const { totalCount, cursor, searchResultList } = imResponse.data;
   // The total number of all conversations where messages meet the search criteria.
   console.log(totalCount);
   // The starting position for the next cloud search. If there is no next position, it indicates that the search result retrieval is complete.
   console.log(cursor);
   // Messages that meet the search criteria are grouped by conversation ID and returned in pages.
   console.log(searchResultList); 
   for (let i = 0; i < searchResultList.length; i++) {
      const searchResultItem = searchResultList[i];
      const { conversationID, messageCount, messageList } = searchResultItem;
      console.log(conversationID);
      console.log(messageCount);。
      console.log(messageList);
    }
}).catch(function(imError) {
   console.error(imError); // Search message failed
});
