Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

v0.0.4

Published

Making native HTTP requests within Cloak applications.

Readme

中文版 | English Version

Http 插件

用于在 Cloak 应用中发起原生 HTTP 请求。请求不经过 WebView,因此不受 CORS 限制,也不携带 WebView 的 cookie。


安装

ohpm install @wisdomgarden/cloak-plugin-http
npm install @wisdomgarden/cloak-plugin-http # 可选,用于 TypeScript 类型

entry/src/main/module.json5 中声明网络权限:

"requestPermissions": [
  {
    "name": "ohos.permission.INTERNET",
    "reason": "$string:permission_internet_reason",
    "usedScene": { "abilities": ["EntryAbility"], "when": "inuse" }
  }
]

使用方法

// GET,params 拼到 URL 查询串上
const res = await Cloak.plugins.Http.get(url, { params: { page: 1 } });
const list = JSON.parse(res.data); // data 恒为原始字符串,解析在 JS 层

// POST JSON,未声明 Content-Type 时按 JSON 编码
await Cloak.plugins.Http.post(url, { username: 'account', password: 'password' });

// POST 表单
await Cloak.plugins.Http.post(url, { username: 'account' }, {
  headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
});

// 4xx / 5xx 不会 reject,只有传输层失败才会
try {
  const res = await Cloak.plugins.Http.get(url, { timeout: 10000 });
  if (res.status >= 400) {
    console.error(res.status, res.statusText);
  }
} catch (e) {
  console.error(e.code, e.message); // e 为 HttpError
}

API

request

request(config: HttpOptions): Promise<HttpResponse>;

发起请求,唯一读取 config.method 的方法。

| 参数 | 类型 | 必填 | 说明 | |---|---|---|---| | config | HttpOptions | 是 | 请求配置,须含 url |

返回值Promise<HttpResponse>


get · delete · head

get(url: string, config?: HttpConfig): Promise<HttpResponse>;
delete(url: string, config?: HttpConfig): Promise<HttpResponse>;
head(url: string, config?: HttpConfig): Promise<HttpResponse>;

| 参数 | 类型 | 必填 | 说明 | |---|---|---|---| | url | string | 是 | 请求地址 | | config | HttpConfig | 否 | 请求配置,method 会被忽略 |

返回值Promise<HttpResponse>


post · put

post(url: string, data?: HttpBody, config?: HttpConfig): Promise<HttpResponse>;
put(url: string, data?: HttpBody, config?: HttpConfig): Promise<HttpResponse>;

| 参数 | 类型 | 必填 | 说明 | |---|---|---|---| | url | string | 是 | 请求地址 | | data | HttpBody | 否 | 请求体,优先于 config.data | | config | HttpConfig | 否 | 请求配置,method 会被忽略 |

返回值Promise<HttpResponse>


类型

HttpMethod

type HttpMethod = 'get' | 'post' | 'put' | 'delete' | 'head' | 'options'; // 大小写均可

HttpParam

type HttpParamValue = string | number | boolean;
type HttpParam = HttpParamValue | HttpParamValue[];

HttpBody

type HttpBody = string | object; // 不支持二进制,值以字符串跨桥

HttpConfig

| 字段 | 类型 | 必填 | 默认值 | 说明 | |---|---|---|---|---| | method | HttpMethod | 否 | 'get' | 仅 request() 读取 | | params | Record<string, HttpParam> | 否 | — | 拼到 URL 查询串,数组值展开成重复的 key | | data | HttpBody | 否 | — | 请求体,GET / HEAD 忽略。字符串原样发送;对象按 Content-Type 编码,x-www-form-urlencoded 走表单,其余走 JSON | | headers | Record<string, string> | 否 | — | 有请求体但未声明 Content-Type 时补 application/json | | timeout | number | 否 | 0 | 毫秒,总耗时上限。0 表示连接和读取各用系统默认的 60s,那不是总耗时上限 | | usingCache | boolean | 否 | false | 是否允许网络库的 HTTP 缓存,与 WebView 缓存无关 | | usingProxy | boolean | 否 | true | 是否走系统代理,关掉后 Charles 等抓包代理也会失效 |

HttpOptions

继承 HttpConfig,另加:

| 字段 | 类型 | 必填 | 默认值 | 说明 | |---|---|---|---|---| | url | string | 是 | — | 为空时不发起请求,直接以 NETWORK_ERROR 拒绝 |

HttpResponse

以下字段恒有值。

| 字段 | 类型 | 说明 | |---|---|---| | status | number | HTTP 状态码,4xx / 5xx 也会正常 resolve | | statusText | string | 仅供展示,由固定码表生成,未收录的状态码返回空串 | | headers | Record<string, string> | key 统一小写,同名多值头用 ', ' 拼成单条 | | url | string | 实际请求的地址,含生成的查询串 | | data | string | 原始响应体,原生侧不解析 |

HttpError

仅在传输层失败时 reject,以下字段恒有值。

| 字段 | 类型 | 说明 | |---|---|---| | code | HttpErrorCode | 失败原因 | | message | string | 形如 [2300028] Timeout was reached,方括号内为 HarmonyOS 原始错误码 |

HttpErrorCode

| 值 | 说明 | |---|---| | TIMEOUT | 超过 timeout 仍未完成 | | SSL_ERROR | 证书校验或 TLS 握手失败 | | UNKNOWN_HOST | 域名解析失败 | | CONNECTION_ERROR | 建立连接失败 | | RESPONSE_TOO_LARGE | 响应体超过 5 MiB | | UNSUPPORTED_METHOD | method 不受支持(如 PATCH),请求未发出 | | NETWORK_ERROR | 其余传输层失败 |

关于 Cloak

Cloak 是专为 HarmonyOS 设计的混合开发框架,类似 CordovaCapacitor,但具备 更轻量更高性能 的特性。

该框架可将 Web 应用快速转换为原生应用,同时通过插件机制访问 HarmonyOS 原生能力。


核心特性

  • 快速打包:将 H5 应用快速编译为 HarmonyOS 应用。
  • 原生能力访问:通过插件机制调用原生接口。
  • WebView 支持:提供高性能 WebView 容器,确保 H5 应用流畅运行。
  • 插件开发:支持开发者自定义插件以扩展原生功能。
