# 2. Overview of HTTP Protocol and File Upload

### 2.1 Basic Concepts of HTTP Protocol
HTTP (Hypertext Transfer Protocol) is a protocol designed for the transmission of hypertext data, such as HTML. It forms the basis of communication between Web servers and clients. HTTP is a stateless protocol, meaning there is no connection between successive requests, and the server does not retain state information about the client.

### 2.2 Principles and Processes of File Upload
File upload is achieved through the POST request in the HTTP protocol. The client encapsulates the file data in the request body and sends it to the server. After receiving the file data, the server processes it and returns the corresponding result. During the file upload process, attention should be paid to data encoding, the transmission of file streams, and the server-side reception and processing.

### 2.3 Common File Upload Methods and Application Scenarios
Common file upload methods include form submission, Ajax asynchronous upload, and upload based on RESTful APIs. File upload is widely used in Web development for scenarios such as image upload, file sharing, and data backup. Implementing file upload functionality can provide richer user interaction and functional expansion.

# 3. Overview of the HTTP Communication Module in LabVIEW

In Chapter 3, we will introduce the overview of the HTTP communication module in LabVIEW, including LabVIEW's network communication capabilities, the usage and features of the HTTP communication module, and how to integrate the HTTP communication module into LabVIEW. Let's delve into these contents.

# 4. Implementing Basic File Upload Functionality in LabVIEW

In this chapter, we will elaborate on how to implement basic file upload functionality in LabVIEW. By creating a simple file upload interface, designing the logical flow and handling methods for file upload, and writing LabVIEW code to achieve file upload functionality, we will help readers quickly master the method of implementing file upload in LabVIEW.

#### 4.1 Creating a Simple File Upload Interface Using LabVIEW

First, we need to create a simple file upload interface in LabVIEW that allows users to select the files they want to upload. Using LabVIEW's Front Panel and Block Diagram, the following functions can be easily implemented:

- Add a file selection button and browser for selecting the file to be uploaded;
- Add an upload button to trigger the file upload operation;
- Add a file upload progress bar to display the upload progress.
