我正在尝试在tiny_http
板条箱中使用multipart
集成:
extern crate multipart;
extern crate tiny_http;
use multipart::server::tiny_http as tiny_http_trait;
use multipart::server::Multipart;
use tiny_http::*;
fn main() {
let server = Server::http("0.0.0.0:8080").unwrap();
loop {
match server.recv() {
Ok(request) => {
let mult = Multipart::from_request(request).unwrap();
}
Err(s) => eprintln!("{:#?}", s),
};
}
}
尝试从请求中提取多部分表单数据时出现以下错误:
error[E0277]: the trait bound `tiny_http::Request: multipart::server::HttpRequest` is not satisfied
--> src/main.rs:13:28
|
13 | let mult = Multipart::from_request(request).unwrap();
| ^^^^^^^^^^^^^^^^^^^^^^^ the trait `multipart::server::HttpRequest` is not implemented for `tiny_http::Request`
|
= help: the following implementations were found:
<&'r mut tiny_http::Request as multipart::server::HttpRequest>
= note: required by `multipart::server::Multipart::<()>::from_request`
该特征实现确实存在,并且我可以直接将其与HttpRequest
函数一起使用:
let boundary = <&mut Request as HttpRequest>::multipart_boundary(&&mut request);
我似乎无法使用相同的语法将tiny_http::Request
用作multipart::server::HttpRequest
中的multipart::server::Multipart::from_request(...)
这是我的Cargo.toml
:
[package]
name = "db_interface"
version = "0.1.0"
authors = [""]
edition = "2018"
[dependencies]
tiny_http = "0.6.2"
[dependencies.multipart]
version = "0.16.1"
features = ["tiny_http"]
答案 0 :(得分:1)
正如编译器告诉您的,您需要一个可变的引用:
<&'r mut tiny_http::Request as multipart::server::HttpRequest>
将请求声明为可变的,然后对其进行引用:
match server.recv() {
Ok(mut request) => {
let mult = Multipart::from_request(&mut request).unwrap();
}
Err(s) => eprintln!("{:#?}", s),
};
