在 Rust 中，我如何处理请求 javascript 的页面

这是因为https://watchparty.me/createRoom只重定向了一次.从curl 的-i标志中判断:

$ curl -X POST -H "Content-Type: application/json" -d '{"video":""}' watchparty.me/createRoom -Li

要更新代码:将您的URL:https://watchparty...替换为https://www.watchparty....以下是经过测试的代码:

use reqwest::header;
// use serde::{Deserialize, Serialize};
// We don't need Room struct and serde actually
// struct Room {
//     name: String
// }

async fn get_room_name() {
    let client = reqwest::Client::builder()
        .build()
        .unwrap();

    let body = r#"{
        "video": ""
    }"#;

    let res = client
        .post("https://www.watchparty.me/createRoom")
        .header(header::USER_AGENT, "mozilla/5.0")
        .header(header::CONTENT_TYPE, "application/json")
        .header(header::ACCEPT, "application/json")
        .body(body)
        .send()
        .await
        .unwrap();

    match res.status() {
        reqwest::StatusCode::OK => {
            println!("Room name: {:?}", &res.text().await.unwrap());
        },
        _ => println!("Error: {}", res.status())
    }
}

#[tokio::main]
async fn main() {
    get_room_name().await;
}

其输出:

$ cargo run
   Compiling soTesting v0.1.0 (/home/cpp23g/rustProjects/soTesting)
    Finished dev [unoptimized + debuginfo] target(s) in 3.41s
     Running `target/debug/soTesting`
Room name: "{\"name\":\"/tasty-animal-heap\"}"

事实上，我们可以干净利落地将其重写为(当然是经过测试的):

use reqwest;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = reqwest::Client::new();
    let res = client.post("https://www.watchparty.me/createRoom")
        .header("Content-Type", "application/json")
        .body(r#"{"video":""}"#)
        .send()
        .await?;
    println!("{}", res.text().await?);
    Ok(())
}
