是否可以使用Iron框架在路由器位置发布JSON文件？

我的main功能看起来像:

fn main() {
    // create the router
    let mut router = Router::new();

    router.post("/example_path/post/:json", post_to_documents);

    let mut mount = Mount::new();

    // mount the router
    mount.mount("/", router);

    Iron::new(mount).http("0.0.0.0:3000").unwrap();
}

与post_to_documents上面列出的是沿着线:

fn post_to_documents(req: &mut Request) -> IronResult
{
    let document_url_encoded = req.extensions.get::()
                                             .unwrap()
                                             .find("json")
                                             .unwrap_or("/");
    // Just return Ok
    Ok(Response::with((status::Ok, "Ok")))
}

我想在document_url_encoded变量中包含JSON数据.(我猜它的命名很差,因为在这种情况下它不会是url/percent编码)

您对HTTP POST的工作原理有误解,或者至少在通过Iron和朋友公开时它是如何工作的.POST请求在URL /路径信息的请求的单独部分中发送,Iron分别公开这两个概念.

您正在使用Iron Router将路径映射到函数并从路径中提取简单参数.您还需要使用Iron Body Parser从POST正文中提取数据.它会自动为您解析JSON,并提供对原始二进制数据的访问.

extern crate iron;
extern crate router;
extern crate mount;
extern crate bodyparser;

use iron::prelude::*;
use iron::status;
use router::Router;
use mount::Mount;

fn post_to_documents(req: &mut Request) -> IronResult {
    match req.extensions.get::().and_then(|r| r.find("json")) {
        Some(name) => println!("The name was {:?}", name),
        None => println!("There was no name!"),
    }

    match req.get::() {
        Ok(Some(json_body)) => println!("Parsed body:\n{:?}", json_body),
        Ok(None) => println!("No body"),
        Err(err) => println!("Error: {:?}", err)
    }

    Ok(Response::with((status::Ok, "Ok")))
}

fn main() {
    let mut router = Router::new();
    router.post("/documents/post/:json", post_to_documents, "new_document");

    let mut mount = Mount::new();
    mount.mount("/", router);

    Iron::new(mount).http("0.0.0.0:3000").unwrap();
}

我有一个名为的文件input.json:

{"key": "value"}

我运行这个命令:

curl -v -i --header "Content-Type: application/json" -X POST -d @input.json http://127.0.0.1:3000/documents/post/awesome

The name was "awesome"
Parsed body:
Object({"key": String("value")})
