reqwest get

use reqwest;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let url = "http://10.0.36.112/";
    let resp = reqwest::get(url)
        .await?
        .text()
        .await?;
    println!("{:#?}", resp);
    Ok(())
}

reqwest post

use reqwest;
use std::collections::HashMap;


fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut map = HashMap::new();
    map.insert("username", "root");
    map.insert("password", "root");

    let client = reqwest::Client::new();
    
    // response body
    let resp = client.post("http://10.0.36.112/login")
        .json(&map)
        .send()
        .await?
        .text()
        .await?;
    println!("{:#?}", resp);
    
    // response header & status
    let resp = client.post("http://10.0.36.112/login")
        .json(&map)
        .send()
        .await?;
    println!("{:#?}", resp.headers());
    println!("{:#?}", resp.status());
    Ok(())
}

reqwest response text to struct

use reqwest;
use std::collections::HashMap;
use serde_derive::{Deserialize};  

#[derive(Deserialize)]
struct Resp {
    status: String,
    msg: String,
}

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut map = HashMap::new();
    map.insert("username", "root");
    map.insert("password", "root");

    let client = reqwest::Client::new();
    let res = client.post("http://10.0.36.112/login")
        .json(&map)
        .send()
        .await?
        .json::<Resp>()
        .await?;
    println!("------msg:{} ---status: {}", res.msg, res.status);
    Ok(())
}

reqwest set headers

use reqwest;
use reqwest::header::HeaderMap;
use reqwest::header::HeaderValue;


fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut header_map = HeaderMap::new();
    let jwe_key = "jwe value";
    header_map.insert("jwe", HeaderValue::from_static(jwe_key));
    let res = client.get("http://10.0.36.112/role/admin")
        .headers(header_map)
        .send()
        .await?
        .text()
        .await?;
    println!("{:#?}", res);
    Ok(())
}
