Part 3. 编写 Client 端
上一节中,我们编写完成了 server 端,现在让我们来编写我们的 client 端并调用我们的 server 端。
首先,创建一个文件 src/bin/client.rs
,输入以下内容:
use lazy_static::lazy_static;
use std::net::SocketAddr;
lazy_static! {
static ref CLIENT: volo_gen::volo::example::ItemServiceClient = {
let addr: SocketAddr = "127.0.0.1:8080".parse().unwrap();
volo_gen::volo::example::ItemServiceClientBuilder::new("volo-example")
.address(addr)
.build()
};
}
#[volo::main]
async fn main() {
tracing_subscriber::fmt::init();
let req = volo_gen::volo::example::GetItemRequest { id: 1024 };
let resp = CLIENT.get_item(req).await;
match resp {
Ok(info) => tracing::info!("{:?}", info),
Err(e) => tracing::error!("{:?}", e),
}
}
然后,在 Cargo.toml
文件中加入所需的依赖,加入后的文件如下:
[package]
name = "volo-example"
version = "0.1.0"
edition = "2021"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
anyhow = "1"
async-trait = "0.1"
lazy_static = "1"
tokio = { version = "1", features = ["full"] }
tracing = "0.1"
tracing-subscriber = "0.3"
pilota = "*"
volo = "*" # we recommend to use the latest framework version for new features and bug fixes
volo-thrift = "*" # we recommend to use the latest framework version for new features and bug fixes
volo-gen = { path = "./volo-gen" }
[profile.release]
opt-level = 3
debug = true
debug-assertions = false
overflow-checks = false
lto = true
panic = 'unwind'
incremental = false
codegen-units = 1
rpath = false
[workspace]
members = ["volo-gen"]
resolver = "2"
接着,新建一个 terminal,执行以下命令,把我们的 server 端跑起来:
$ cargo run --bin server
最后,我们再回到当前目录,执行以下命令,即可看到执行成功:
$ cargo run --bin client
大功告成!
