Once authenticated, users can send or received messages such as: text, photo, video, audio, location, contact... To send a message contains media content (photo, video, audio, file...), you need to upload media content to your server first. Then you use Stringee SDK to send the uploaded url.
Create a message by using NewMessageInfo Object:
// Text message
const msg = new NewMessageInfo({
type: 1,
convId: "YOUR_CONVERSATION_ID",
message: {
content: 'Hello'
}
});In which:
message: {
// Audio
audio: {
duration: // number type, value in milliseconds.
filePath: // audio file's url.
},
// Contact
contact: {
vcard: // contact as vcard, string value.
}
// File
file: {
filePath: // file's url.
filename: ,
length: // number type, number of bytes
}
// Location
location: {
lat: // number type, latitude
lon: // number type, longitude
}
// Photo
photo: {
filePath: // photo file's url.
thumbnail: // thumbnail file's url.
ratio: // number type
}
// Text
content: ''
// Video
video: {
filePath: // photo file's url.
thumbnail: // thumbnail file's url.
ratio: // number type
duration: // number type, value in milliseconds.
}
// Sticker
sticker: {
name: // string type
category: // string type
}
}Ex: Location message.
const msg = new NewMessageInfo({
type: 9,
convId: "YOUR_CONVERSATION_ID",
message: {
location: {
lat: 123
lon: 456
}
}
});Send a Message by calling:
conversation.sendMessage(msg).then(() => {
console.log('sendMessage success');
}).catch(console.log);Messages are stored on Stringee server and cached on Local Database as well. You can get messages as follows:
Get local messages
To get local messages of a conversation, you call:
conversation.getLocalMessages(count, isAscending).then(messages => {
messages.map(message => {
console.log('getLocalMessages', message);
});
}).catch(console.log);In which:
Get last messages
To get latest messages from Stringee server, you call:
conversation.getLastMessages(count, isAscending, loadDeletedMessage, loadDeletedMessageContent).then(messages => {
messages.map(message => {
console.log('getLastMessages', message);
});
}).catch(console.log);In which:
Get messages after
To get a list of messages tied to a conversation from server which have sequence greater than seq, you call:
conversation.getMessagesAfter(sequence, count, isAscending, loadDeletedMessage, loadDeletedMessageContent).then(messages => {
messages.map(message => {
console.log('getMessagesAfter', message);
});
}).catch(console.log);In which:
Get messages before
To get a list of messages tied to a conversation from server which have sequence smaller than seq, you call:
conversation.getMessagesBefore(sequence, count, isAscending, loadDeletedMessage, loadDeletedMessageContent).then(messages => {
messages.map(message => {
console.log('getMessagesBefore', message);
});
}).catch(console.log);In which:
Stringee keeps track of the recipient status of each message. There are five possible statuses: INITIALIZE, SENDING, SENT, DELIVERED, READ. Stringee automatically updates the recipient status to sent, delivered. The only update your app can perform is to mark a conversation's messages as read:
conversationm.markConversationAsRead().then(() => {
console.log('markConversationAsRead success');
}).catch(console.log);Stringee notify you the status update of a message via the onObjectChange event of StringeeClient.
To delete a message, you call:
conversation.deleteMessage(messageId).then(() => {
console.log('deleteMessage success');
}).catch(console.log);
