JSONRPC v2客户端

特性

• 日志记录
• async-std运行时
• APIKey选项（作为HTTP头发送）

示例

let service_address = jsonrpc_v2_client::ServiceAddress::new("127.0.0.1:8082", "/api");
let method = "add";
let params = jsonrpc_v2_client::Params([10.5, 20.5]);
let id = "0";
let request = jsonrpc_v2_client::Request::new(method, params, id);
// Without API KEY
let response = request.send(&service_address, None);
println!("{}", response);
// Or with API KEY
let api_key = jsonrpc_v2_client::APIKey::new("API-KEY", "abcdef123456");
let response = request.send(&service_address, Some(&api_key));
println!("{}", response);
// Access JSON field
println!("{}", response["result"]);
println!("{}", response["error"]);
println!("{}", response["id"]);

日志记录

日志目标名称为：jsonrpc_v2_client
使用log4rs的示例

文件：config.yaml

# Scan this file for changes every x seconds
refresh_rate: 30 seconds

appenders:
  stdout:
    kind: file
    path: "log/logs/stdout.log"
    encoder:
      pattern: "{d} - {m}{n}"

  jsonrpc_v2_client:
    kind: file
    path: "log/logs/jsonrpc_v2_client.log"
    encoder:
      pattern: "{d} - {m}{n}"

root:
  level: info
  appenders:
    - stdout

  jsonrpc_v2_client:
    level: trace
    appenders:
      - jsonrpc_v2_client
    additive: false
