This is just a request library to support browsers and MiniProgram platforms.

onUploadProgress	(info: { total: number, loaded: number }) => void	The uploading progress event

NOTE 1: The method field

1. Some MiniProgram platforms can only support "GET" or "POST" methods, so using a RESTful API is not the best solution for MiniPrograms.

NOTE 2: The files field

1. In browsers, the file is represented as a Blob or File object, whereas in other MiniProgram platforms, the file is represented as a string filePath.
2. MiniProgram platforms doese not suport multiple files uploading in once.

NOTE 3: The responseType field

1. The values of blob and document can only be used on browser.
2. The responseType can not be used with files on MiniProgram platforms.

NOTE 4: The withCredentials field

1. This can only be used on browser.

Return Promise<InvokeResult>

The InvokeResult is

name	type	description
statusCode	number	Response status code
data	any	Response body
headers	Record<string, string>	Response headers

Demo

import { request } from '@huolala-tech/request';

async function main() {
  const res = await request({
    method: 'POST',
    url: 'http://localhost/api',
    data: {
      xxx: 'xxx',
    },
  });

  if (res.statusCode === 200) {
    console.log(res.data);
  }
}

Advanced Features

1. Interceptors

Taking into account the learning cost, our interceptors API design is modeled after the Axios.

import { request, interceptors } from '@huolala-tech/request';

// Add Authorization: xxx header for all requests.
interceptors.request.use((req) => {
  req.headers = { ...Object(req.headers), Authorization: 'xxx' };
});

// If any request responds with a 401 code, go to login.
interceptors.response.use((res) => {
  if (res.statusCode === 401) {
    location.href = 'http://blahblahblah/';
  }
});

request({ method: 'POST', url: 'http://localhost/api/user' });

2. New Instance

You can use create method to create a pairs request and intercepters and set a common request parameters.

import { create } from '@huolala-tech/request';
const { request, interceptors } = create({
  header: {
    'x-request-with': '@huolala-tech/request'
  }
});

// TODO

NOTE: The created pairs is an isolated instance, global intercepters will not act on the created request.
