这是我创建ZIP文件的示例代码。
exampleFunction: function(req, res, next){
Test.create({....
}).exec(function (error, HObj){
if(error) {console.log('error'+ error); return next(error)};
if(!HObj) {console.log('error'); return res.send({error : "error"});}
var generatedUUID=uuid.v4().replace(/[^a-zA-Z0-9]/g,'_');
var output = fs.createWriteStream(path.join(__dirname,'../../assets/images/'+generatedUUID+'.zip'));
zipArchive.pipe(output);
zipArchive.bulk([{ expand: true, cwd: path.join(__dirname,'../../assets/images/'), src: ['abc.mp3','xyz.mp3'], dest: 'newdir'}]);
zipArchive.finalize();
return res.send({zipName : generatedUUID+'.zip'});
});
}
在sailsjs控制器中连续调用此方法，导致mongo错误[error[Error (E_UNKNOWN) Encountered an unexpected error] Details: MongoError: topology was destroyed]。
error: Sending 500 ("Server Error") response:
Error (E_UNKNOWN) :: Encountered an unexpected error
MongoError: topology was destroyed
