参考Axum文档:docs.rs
大家好，我正在尝试使用HTML5表单和Rust Axum创建一个简单的文件上传。
问题是，虽然任何正常的文件工作，较大的文件(特别是视频文件)，我想上传太大。Axum(后来的Tokio)恐慌，因为Field大小对于文件上传来说太大了。
我似乎找不到任何关于扩展流限制的有用信息。
<form action="/upload" method="POST" enctype="multipart/form-data">
<input type="file" name="filename" accept="video/mp4">
<input type="submit" value="Upload video">
</form>
async fn upload(mut multipart: Multipart) {
while let Some(mut field) = multipart.next_field().await.unwrap() {
let name = field.name().unwrap().to_string();
let data = field.bytes().await.unwrap();
println!("Length of `{}` is {} bytes", name, data.len());
}
}
thread 'tokio-runtime-worker' panicked at 'called `Result::unwrap()` on an `Err` value: MultipartError { source: failed to read stream: failed to read stream: length limit exceeded }', src/main.rs:84:40
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
thread 'tokio-runtime-worker' panicked at 'called `Result::unwrap()` on an `Err` value: MultipartError { source: failed to read stream: failed to read stream: length limit exceeded }', src/main.rs:84:40
thread 'tokio-runtime-worker' panicked at 'called `Result::unwrap()` on an `Err` value: MultipartError { source: failed to read stream: failed to read stream: length limit exceeded }', src/main.rs:84:40
为了不影响这段代码的主要部分，我省略了路由器，但它的应用程序是:.route("/upload", post(upload))，根据Axum文档中显示的示例。
快速提示:要启用Multipart文件上传，必须添加Cargo特性标志" Multipart "阿克苏姆。
任何帮助都是感激的。谢谢你。
您尝试过Axum的DefaultBodyLimit服务吗?
use axum::{
Router,
routing::post,
body::Body,
extract::{DefaultBodyLimit, RawBody},
http::Request,
};
let app = Router::new()
.route(
"/",
// even with `DefaultBodyLimit` the request body is still just `Body`
post(|request: Request<Body>| async {}),
)
.layer(DefaultBodyLimit::max(1024));
我在这里找到了这个例子
