使用知晓云开放 API 上传文件需要以下两个步骤:

1. 获取上传文件所需授权凭证和上传地址

v2.1 接口规范了返回参数的输出,使用更方便。原获取上传文件所需授权凭证和上传地址 v1 接口已被废弃。

接口

POST https://cloud.minapp.com/oserve/v2.1/upload/

参数说明

Content-Type: application/json

参数 类型 必填 说明
filename String N 上传的文件名
category_id String N 上传文件的所属分类,格式为文件分类的 ID 数组

返回参数

参数 类型 说明
id String 上传的文件 ID
policy String 文件上传配置
authorization String 文件上传凭证
path String 上传成功后的访问地址 URL
upload_url String 上传文件的目标地址
name String 文件名
cdn_path String 文件在 CDN 中的相对路径
created_at Integer 文件创建时间戳

代码示例

curl -X POST \
-H "Authorization: Bearer 52ce223c5adbb66fa188a959a8b08889adb3580c" \
-H "Content-Type: application/json" \
-d '{
      "filename":"crop.gif",
      "category_id":"5a1ba7b708443e7fc5f2fb18"
    }' \
https://cloud.minapp.com/oserve/v2.1/upload/
var request = require('request');

var opt = {
  uri: 'https://cloud.minapp.com/oserve/v2.1/upload/',
  method: 'POST',
  headers: {
    Authorization: `Bearer ${token}`
  },
  json: {   // 指定 data 以 "Content-Type": 'application/json' 传送
    filename: 'aTest.xlsm',
    category_id: '5a3b569109a80579061d63xx'
  }
}

request(opt, function(err, res, body) {
  console.log(res.statusCode, body)
})
<?php
$param = array(
  'filename' =>'aTest.xlsm',
  'category_id'=> '5a3b569109a80579061d63xx'
);
$url = 'https://cloud.minapp.com/oserve/v2.1/upload/';

$ch = curl_init();
$header = array(
  "Authorization: Bearer {$token}",
  'Content-Type: application/json; charset=utf-8'
);

curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($param));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);

$res['response'] = curl_exec($ch); // 反馈结果
$res['status_code'] = curl_getinfo($ch, CURLINFO_HTTP_CODE); // 请求状态码
curl_close($ch);

返回示例

    "created_at": 12344566
}

状态码说明

200 获得授权凭证成功,400 参数错误(不支持上传的文件格式),404 找不到文件分类 ID

2. 使用上一步获取的授权凭证和上传地址,进行文件上传

接口

POST {UPLOAD_URL}

UPLOAD_URL 是调用上一步的接口所返回的字段 upload_url 的值,形如:

  https://v0.api.upyun.com/cloud-minapp-287

参数说明

Content-Type: multipart/form-data

参数 类型 必填 说明
authorization String Y 授权凭证
file String Y 上传的文件流
policy String Y 授权凭证

代码示例

curl -X POST \
-H "Authorization: Bearer 52ce223c5adbb66fa188a959a8b08889adb3580c" \
-H "Content-Type: multipart/form-data" \
