【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

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

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"}

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

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

use gostd::strings;

fn main() {

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

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", " ", ""],
strings::Split(" xyz ", "")
);
assert_eq!(vec![""], strings::Split("", "Bernardo O'Higgins"));
}

use gostd::strings;

fn main() {

assert_eq!(4, strings::Index("chicken", "ken"));
assert_eq!(-1, strings::Index("chicken", "dmr"));
}

use gostd::strings;

fn main() {

let s = vec!["foo", "bar", "baz"];
assert_eq!("foo, bar, baz", strings::Join(s, ", "));
}

use gostd::strings;

fn main() {

assert_eq!("GOPHER", strings::ToUpper("Gopher"));
}

use gostd::strings;

fn main() {

assert_eq!("gopher", strings::ToLower("Gopher"));
}

time模块

fn main() {
use gostd_time as time;

let mut t = time::Date(2009, 11, 10, 14, 30, 12, 13, time::UTC.clone());
assert_eq!(
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()
);
println!("CST: {}", t);
}
