### 版本
|
||||
> 共有2个版本, 一个传统版本, 基于`XMLHttpRequest`; 另一个是新一代版本, 基于`window.fetch()`。
|
||||
|
||||
**`注意:`**
|
||||
|
||||
由于`window.fetch()`只支持`http/https`协议, 所以在一些特殊的环境下(如electron等), 请使用传统版。
|
||||
|
||||
### 2个版本的区别
|
||||
|
||||
1. 超时的返回值不一样。fetch版没有额外处理, 全由原生返回; 传统版为处理过, 统一返回`Response对象`。
|
||||
|
||||
2. 缓存参数不一致, 传统版只有传入`no-store`才不会缓存,其他任何值都会缓存, 缓存机制由headers及浏览器机制决定。 fetch版支持完整的参数, 详见原生fetch文档。
|
||||
|
||||
3. 验证机制,传参不一样。传统版credentials为布尔值; fetch版本则是支持omit, same-origin, include。
|
||||
|
||||
|
||||
### 示例
|
||||
|
||||
```js
|
||||
import fetch from '//dist.bytedo.org/fetch/dist/index.js' // 传统版
|
||||
// import fetch from '//dist.bytedo.org/fetch/dist/next.js' // fetch版
|
||||
|
||||
|
||||
fetch('/get_list', {body: {page: 1}})
|
||||
.then(r => r.json())
|
||||
.then(list => {
|
||||
console.log(list)
|
||||
})
|
||||
|
||||
|
||||
// 创建一个新的fetch实例, 可传入新的基础域名, 和公共参数等
|
||||
var f1 = fetch.create('//192.168.1.101', {headers: {token: 123456}})
|
||||
|
||||
f1('/get_list', {body: {page: 1}})
|
||||
.then(r => r.json())
|
||||
.then(list => {
|
||||
console.log(list)
|
||||
})
|
||||
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
### APIs
|
||||
|
||||
#### 1. fetch(url[, options<Object>])
|
||||
> 发起一个网络请求, options的参数如下。 同时支持配置公共域名, 公共参数。
|
||||
|
||||
+ method`<String>` 默认GET, 可选GET/POST/PUT/DELETE...
|
||||
+ body`<Any>` 要发送的数据, 如果是不允许有`body`的方式, 会被自动拼接到url上
|
||||
+ cache`<String>` 是否缓存,
|
||||
+ credentials`<String/Boolean>` 是否校验
|
||||
+ signal`<Object>` 网络控制信号, 可用于中断请求
|
||||
+ timeout`<Number>` 超时时间, 默认30秒, 单位毫秒
|
||||
|
||||
|
||||
```js
|
||||
fetch.BASE_URL = '//192.168.1.100'
|
||||
fetch.__INIT__ = {headers: {token: 123456}} // 2.x 之后将废弃, 不推荐使用了
|
||||
// 1.2.0开始支持注入
|
||||
fetch.inject.request(function(conf) {
|
||||
// 无需返回值, 但需要注意这是引用类型,不要对带个conf赋值
|
||||
conf.headers.token = 123456
|
||||
})
|
||||
|
||||
// 响应注入, 需要有返回值
|
||||
fetch.inject.response(function(res) {
|
||||
return res.json()
|
||||
})
|
||||
```
|
||||
|
||||
|
||||
#### 2. fetch.create([BASE_URL][, options<Object>])
|
||||
> 创建一个新的fetch实例, 可以无限创建多个实例(用于同一个项目中有多组不同的接口)。
|
||||
|
||||
```js
|
||||
var another = fetch.create('//192.168.1.101')
|
||||
// 新创建的实例, 也支持注入
|
||||
another.inject.request(function(conf) {
|
||||
conf.headers.token = 123456
|
||||
})
|
||||
|
||||
another.inject.response(function(res) {
|
||||
return res.json()
|
||||
})
