rust中使用Reqwest解析JSON

Cargo.toml

serde_json = "1.0"
serde = "1.0"
serde_derive = "1.0"

1、引入serde_derive

#[macro_use]
extern crate serde_derive;

2、按照目标json定义结构体

#[derive(Deserialize, Debug)]
struct Forecast {
    time: String,
    values: Vec<f32>,
    status: String,
    uptime: String,
    msg: String,
}

3、解析

let res: Forecast = reqwest::get(RAIN_API).unwrap().json().unwrap();
println!("{:#?}", res.msg);
