the risk of data can be repeatedly saved. Because in asynchronous execution, you have no way of ensuring which thread executes first, which thread executes, and all requests initiated by the client are not executed sequentially as we think. A better solution is to create a unique index in all tables in the MONGO database. In fact, MongoDB creates a unique index (can be canceled) for all tables by default for a _id field. If you want to create an index from Node.js in the Mongoose.schema, you ca

JSON (JavaScriptObjectNotation) is a simple data format, which is lighter than xml. JSON is a JavaScript native format, which means that no special API or toolkit is required to process JSON data in JavaScript. JSON rules are simple: the object is an unordered set of 'name/value' pairs. An object starts with "{" (left parenthesis) and ends with "}" (right Parenthesis. Each "name" is followed by a ":" (colon); "," (comma) is used to separate the "name/value" pairs. Detailed reference http://www.j

Even if you don't try again, you have to make a lot of internal changes. The following code example is a simple factory type that can produce mobile phones and only IPhone and Samsung mobile phones. If you want to produce a Xiaomi mobile phone, sorry, it cannot be produced at present. RuntimeException, you have to make it. If you con
