【大家的项目】Gostd update to v0.2.6 ---- 新增了httpclient实现

go std 在 Rust 中的实现

todo

• Go基础类型在rust实现，在gostd::builtin 中,比如 int64 = i64, int32 = i32
• 强制转换宏,例如 2 as i64 等价 int64!(2) 跟Go的int64(2)就多个！
• time库在rust实现 gostd::time
• time库支持macOSX 和linux平台，通过libc库调用C函数实现 time::Now()
• time，支持各种格式显示时间。
• docs.rs文档增加例子程序"RUN"按钮,但是要复制代码本地运行,在rust play运行不了(因为下载量没到前100)。
• time支持local时区信息自动从系统读取，可以用time::Now()获取本地时间。
• strings模块，字符串处理函数已完成。除了Reader相关方法还没全实现。(version >=0.2.3)
• strings模块, 完成剩余的方法实现。(version >=0.2.4)
• io模块,完成部分接口例如Reader，Writer等。(version >=0.2.4)
• http模块的client客户端功能，支持http和https。(version >=0.2.6)

独立发布包

独立发布gostd_time，代码等价于 use gostd::time 。

独立发布gostd_builtin, 代码等价于 use gostd::builtin 。

使用例子

http模块

client客户端

1. POST

代码语言：javascript复制

use gostd::net::http;
fn main() -> Result<(), std::io::Error> {
    let url = "https://petstore.swagger.io/v2/pet";
    let postbody = r#"{"id":0,"category":{"id":0,"name":"string"},"name":"doggie","photoUrls":["string"],"tags":[{"id":0,"name":"string"}],"status":"available"}"#
   .as_bytes()
   .to_vec();
    let response = http::Post(url, "application/json", Some(postbody))?;

    println!(
        "{}",
        String::from_utf8(response.Body.expect("return body error")).unwrap()
    );

    Ok(())
}

或者

代码语言：javascript复制

use gostd::net::http::{Client, Method, Request};

fn main() -> Result<(), std::io::Error> {

    let url = "https://petstore.swagger.io/v2/pet";

    let postbody = r#"{
      "id": 0,
      "category": {
        "id": 0,
        "name": "string"
      },
      "name": "doggie",
      "photoUrls": [
        "string"
      ],
      "tags": [
        {
          "id": 0,
          "name": "string"
        }
      ],
      "status": "available"
    }"#
    .as_bytes()
    .to_vec();

    let mut req = Request::New(Method::Post, url, Some(postbody))?;

    req.Header.Set("accept", "application/json");
    req.Header.Set("Content-Type", "application/json");
    let mut client = Client::New();
    let response = client.Do(&mut req)?;

    println!(
        "{}",
        String::from_utf8(response.Body.expect("return body error")).unwrap()
    );

    Ok(())
}

// output
// {"id":92233723685477587,"category":{"id":,"name":"string"},"name":"doggie","photoUrls":["string"],"tags":[{"id":,"name":"string"}],"status":"available"}

1. GET

代码语言：javascript复制

use gostd::net::http;

fn main() -> Result<(), std::io::Error> {
    let url = "https://petstore.swagger.io/v2/pet/findByStatus?status=available";
    let response = http::Get(url)?;

    println!(
        "{}",
        String::from_utf8(response.Body.expect("return body error")).unwrap()
    );

    Ok(())
}

或者

代码语言：javascript复制

use gostd::net::http::{Client, Method, Request};

fn main() -> Result<(), std::io::Error> {

    let url = "https://petstore.swagger.io/v2/pet/findByStatus?status=available";
    let mut req = Request::New(Method::Get, url, None)?;
    req.Header.Set("Content-Type", "application/json");

    let mut client = Client::New();

    let response = client.Do(&mut req)?;
    println!(
        "{}",
        String::from_utf8(response.Body.expect("return body error")).unwrap()

    Ok(())

strings模块

        "moo moo moo",
        strings::ReplaceAll("oink oink oink", "oink", "moo")
    );
}

1. 字符串分割 strings::Split()

use gostd::strings;

fn main() {

    assert_eq!(vec!["a", "b", "c"], strings::Split("a,b,c", ","));
    assert_eq!(
        vec!["", "man ", "plan ", "canal panama"],
        strings::Split("a man a plan a canal panama", "a ")
    );
    assert_eq!(
        vec!["", " ", "x", "y", "z", " ", ""],

        t.String(),
        "2009-11-10 14:30:12.000000013  0000 UTC".to_string()
    );
    println!("UTC: {}", t);
    let cst_zone = time::FixedZone("CST", 8 * 3600); //北京时区 CST = UTC时区 8小时
    t.In(cst_zone);
    assert_eq!(
        t.String(),
        "2009-11-10 22:30:12.000000013  0800 CST".to_string()
