我正在尝试在聊天中发送图片或txt文件。我正在使用SendBird react-native sdk(https://docs.sendbird.com/javascript)。
FilePickerManager.showFilePicker(null, (response) => {
console.log('Response = ', response);
if (Platform.OS === 'android') {
sb.enableStateChange();
}
if (response.didCancel) {
console.log('User cancelled file picker');
}
else if (response.error) {
console.log('FilePickerManager Error: ', response.error);
}
else if (response.customButton) {
console.log('User tapped custom button: ', response.customButton);
}
else {
debugger;
let source = { uri: response.uri };
const _SELF=this;
if (response.name) {
source['name'] = response.fileName
} else {
paths = response.uri.split("/")
source['name'] = paths[paths.length - 1];
}
if (response.type) {
source['type'] = response.type;
}
console.log('source = ',source);
const CHECK_IMAGE_URI_INTERVAL = Platform.OS === 'android' ? 300 : 100;
// This is needed to ensure that a file exists
setTimeout(() => {
// Use getSize as a proxy for when the image exists
Image.getSize(
response.uri,
() => {
_SELF.state.channel.sendFileMessage(source, function (message, error) {
if (error) {
console.log(error);
return;
}
var _messages = [];
_messages.push(message);
if (_SELF.state.lastMessage && message.createdAt - _SELF.state.lastMessage.createdAt > (1000 * 60 * 60)) {
_messages.push({ isDate: true, createdAt: message.createdAt });
}
var _newMessageList = _messages.concat(_SELF.state.messages);
_SELF.setState({
messages: _newMessageList,
dataSource: _SELF.state.dataSource.cloneWithRows(_newMessageList)
});
_SELF.state.lastMessage = message;
});
this.setState({
file: response
});
}
);
}, CHECK_IMAGE_URI_INTERVAL);
}
});
