reqwest 实现的 http server 和 client

用 https://github.com/seanmonstar/reqwest

cargo add reqwest -F json
cargo add tokio -F full

一、client

1.1 post

async fn http_post<T: Serialize>(addr: String, body: T) -> Result<(), reqwest::Error> {let client = reqwest::Client::new();let resp = client.post(addr.clone()).json(&body).send().await?;if resp.status() == StatusCode::OK || resp.status() == StatusCode::NO_CONTENT {println!("http调用 {:?} 成功, 返回码 {:?}",addr.clone(),resp.status());} else {let body_json = serde_json::to_string(&body).unwrap_or_else(|_| "".to_string());println!("http调用 {:?} 成功, 返回码 {:?}, body: {}, 返回体 {:?}",addr.clone(),resp.status(),body_json,resp.text().await?);}Ok(())
}

调用方式如下：

async fn f(arg: Arg) -> Result<(), reqwest::Error> {#[derive(Debug, Serialize)]struct Body {#[serde(rename = "UserID")]user_id: i64,#[serde(rename = "Arr")]arr: Vec<String>,}let addr = format!("http://{}:123/v1/user", arg.server_ip);let req_body = Body {user_id: 1,arr: vec!["a".to_string(),"b".to_string(),],};http_post(addr.clone(), req_body).await?;Ok(())
}
