  1. Open the Cargo.toml file that has been generated for you
  2. Under [dependencies], if you didn't do so in the last recipe, add the following lines:
reqwest = "0.8.5"
serde = "1.0.30"
serde_derive = "1.0.30"
  1. If you want, you can go to request's (, serde's (, and serde_derive's ( pages to check for the newest versions and use those ones instead
  2. In the folder src/bin, create a file called
  3. Add the following code and run it with cargo run --bin making_requests:
1   extern crate reqwest;
2   #[macro_use]
3   extern crate serde_derive;
5   use std::fmt;
7   #[derive(Serialize, Deserialize, Debug)]
8   // The JSON returned by the web service that hands posts out
9   // it written in camelCase, so we need to tell serde about that
10  #[serde(rename_all = "camelCase")]
