不满足特征界限 `actix_identity::Identity: FromRequest`
the trait bound `actix_identity::Identity: FromRequest` is not satisfied
我正在关注 this tutorial 使用 actix-web、tera 和 diesel 创建一个简单的网站。
我目前使用 actix-identity 为登录用户添加会话。据我了解，我需要将中间件附加到应用程序。但是出现了一些错误。
其中一个说 the trait bound 'actix_identity::Identity: FromRequest' is not satisfied。
我试图阅读 actix-identity 文档，但不知道我的代码有什么问题。有人说我可能忘记了 return，但找不到。
我才学了几天rust，希望有人能给我个线索。
这是代码
main.rs
use actix_web::{web, web::Data, App, HttpResponse, HttpServer, Responder};
use tera::{Tera, Context};
use actix_identity::{CookieIdentityPolicy, Identity, IdentityService};
async fn login(tera: Data<Tera>, id: Identity) -> impl Responder {
let mut data = Context::new();
data.insert("head_title", "Login");
if let Some(id) = id.identity() {
return HttpResponse::Ok().body("Already logged in")
}
let rendered = tera.render("login.html", &data).unwrap();
return HttpResponse::Ok().body(rendered)
}
#[actix_web::main]
async fn main() -> std::io::Result<()> {
HttpServer::new(move || {
let tera = Tera::new("templates/**/*").expect("Failed to parse template file");
App::new()
.wrap(IdentityService::new(
CookieIdentityPolicy::new(&[0;32])
.name("auth-cookie")
.secure(false)
))
.app_data(web::Data::new(tera))
.route("/login", web::get().to(login))
})
.bind(("127.0.0.1", 8080))?
.run()
.await
}

我克隆了 this repo 来与我的代码进行比较，它有效，但我找不到任何显着差异。
错误消息没有帮助（有 open issue for this）。
您正在使用 actix-identity 0.3，这取决于 actix-web 3，而您的主要应用程序功能正在使用 actix-web 4，这导致 Rust 包含 both actix-web 3 和 4 进入您的应用程序。 actix_identity::Identity 从 actix-web 3 实现 FromRequest，而不是 actix-web 4，这就是错误消息试图说明的内容。
要修复，您需要确保两个箱子的版本兼容。在这种情况下，您可以简单地将 actix-identity 升级到 0.4.0，这取决于 actix-web 4.
