该文提供了使用Rust的Reqwest库进行multipart文件上传的客户端代码示例，包括异步(async)和阻塞(blocking)两种方式。依赖项包括anyhow、reqwest、tokio和tokio-util。服务端示例使用了Spring框架处理文件上传请求。代码示例详细展示了如何构造multipart表单数据并发送POST请求。

这里写自定义目录标题

客户端示例代码

示例包含了async和blocking两种，根据自身需要合理修改依赖项

依赖项 Cargo.toml

[package]
edition = "2021"
name = "file-upload-client"
version = "0.1.0"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
anyhow = { version = "*" }
reqwest = { version = "*", features = ["stream", "multipart", "blocking"] }
tokio = { version = "*", features = ["macros", "rt-multi-thread"] }
tokio-util = { version = "*", features = ["codec"] }

示例代码 main.rs

use anyhow::{
   
   Ok, Result};
use reqwest::{
   
   
    multipart::{
   
   self, Part},
    Body,
};
use tokio_util::codec::{
   
   BytesCodec, FramedRead};

#[tokio::main]
async fn main() {
   
   
    let filename = upload().await.unwrap();
    println!("{}", filename)
