# Vue-jsonp
|
|

|
|
|
|
A tiny library for handling JSONP request.
|
|
|
|
## Quick Start
|
|
|
|
As Vue plugin:
|
|
|
|
```ts
|
|
import { VueJsonp } from 'vue-jsonp'
|
|
|
|
// Vue Plugin.
|
|
Vue.use(VueJsonp)
|
|
|
|
// Now you can use "$jsonp" on Vue components.
|
|
const vm = new Vue()
|
|
const data = await vm.$jsonp('/some-jsonp-url', {
|
|
myCustomUrlParam: 'veryNice'
|
|
})
|
|
```
|
|
|
|
Use function directly:
|
|
|
|
```ts
|
|
import { jsonp } from 'vue-jsonp'
|
|
|
|
// Pass a response type.
|
|
const data = await jsonp<string>('/some-jsonp-url', {
|
|
myCustomUrlParam: 'veryNice'
|
|
})
|
|
```
|
|
|
|
## Send data and set query & function name
|
|
|
|
### Send data
|
|
|
|
```ts
|
|
// The request url will be "/some-jsonp-url?type=admin&date=2020&callback=jsonp_{RANDOM_STR}".
|
|
const data = await jsonp('/some-jsonp-url', {
|
|
type: 'admin',
|
|
date: 2020
|
|
})
|
|
```
|
|
|
|
### Custom query & function name
|
|
|
|
The url uniform is `/url?{callbackQuery}={callbackName}&...` and the default is `/url?callback=jsonp_{RANDOM_STRING}&...`.
|
|
|
|
And you can change it like this:
|
|
|
|
```ts
|
|
// The request url will be "/some-jsonp-url?type=admin&date=2020&cb=jsonp_func".
|
|
jsonp('/some-jsonp-url', {
|
|
callbackQuery: 'cb',
|
|
callbackName: 'jsonp_func',
|
|
type: 'admin',
|
|
date: 2020
|
|
})
|
|
```
|
|
|
|
## Module exports
|
|
|
|
- `VueJsonp: PluginObject<never>`
|
|
|
|
- `jsonp<T>: (url: string, param?: IJsonpParam, timeout?: number) => Promise<T>`
|
|
|
|
## API
|
|
|
|
### IJsonpParam
|
|
|
|
IJsonpParam is the type of param for jsonp function.
|
|
|
|
```ts
|
|
/**
|
|
* JSONP parameter declaration.
|
|
*/
|
|
interface IJsonpParam {
|
|
/**
|
|
* Callback query name.
|
|
* This param is used to define the query name of the callback function.
|
|
*
|
|
* @example
|
|
* // The request url will be "/some-url?myCallback=jsonp_func&myCustomUrlParam=veryNice"
|
|
* const result = await jsonp('/some-url', {
|
|
* callbackQuery: 'myCallback',
|
|
* callbackName: 'jsonp_func',
|
|
* myCustomUrlParam: 'veryNice'
|
|
* })
|
|
*
|
|
* @default callback
|
|
*/
|
|
callbackQuery?: string
|
|
|
|
/**
|
|
* Callback function name.
|
|
* This param is used to define the jsonp function name.
|
|
*
|
|
* @example
|
|
* // The request url will be "/some-url?myCallback=jsonp_func&myCustomUrlParam=veryNice"
|
|
* const result = await jsonp('/some-url', {
|
|
* callbackQuery: 'myCallback',
|
|
* callbackName: 'jsonp_func',
|
|
* myCustomUrlParam: 'veryNice'
|
|
* })
|
|
*
|
|
* @default jsonp_ + randomStr()
|
|
*/
|
|
callbackName?: string
|
|
|
|
/**
|
|
* Custom data.
|
|
*/
|
|
[key: string]: any
|
|
}
|
|
```
|
|
|
|
## Example
|
|
|
|
```ts
|
|
import Vue from 'vue'
|
|
import { VueJsonp } from 'vue-jsonp'
|
|
|
|
Vue.use(VueJsonp)
|
|
|
|
const vm = new Vue()
|
|
const { code, data, message } = await vm.$jsonp<{
|
|
code: number,
|
|
message: string,
|
|
data: {
|
|
id: number,
|
|
nickname: string
|
|
}
|
|
}>('/my-awesome-url', {
|
|
name: 'MyName', age: 20
|
|
})
|
|
|
|
assert(code === 0)
|
|
assert(message === 'ok')
|
|
assert(data.id === 1)
|
|
assert(data.nickname === 'John Smith')
|
|
```
|
|
|
|
```ts
|
|
import { jsonp } from 'vue-jsonp'
|
|
|
|
const result = await jsonp<string>('/my-awesome-url')
|
|
assert(result === 'such a jsonp')
|
|
```
