azure-函数多相

解析 Azure 函数多段/形式数据的模块.

说明: Will也会在任何节点的 HTTP 请求对象上工作, 将 Azure 函数的 Httprequest 对象放在一边, 因为此软件包是基于 busboy .

安装

npm i @anzp/azure-function-multipart

实例

解析 Azure 函数的多段/形式数据 。 这将返回解析过的字段和文件作为响应 .

用于类型脚本 :

import { AzureFunction, Context, HttpRequest } from "@azure/functions";
import parseMultipartFormData from "@anzp/azure-function-multipart";

const httpTrigger: AzureFunction = async function (
  context: Context,
  req: HttpRequest
): Promise<void> {
  const { fields, files } = await parseMultipartFormData(req);
  context.log("HTTP trigger function processed a request.");
  const name = req.query.name || (req.body && req.body.name);
  const responseMessage = {
    fields,
    files,
  };

  context.res = {
    // status: 200, /* Defaults to 200 */
    body: responseMessage,
  };
};

export default httpTrigger;

对于 Java 脚本 :

const parseMultipartFormData = require("@anzp/azure-function-multipart")
  .default;

module.exports = async function (context, req) {
  const { fields, files } = await parseMultipartFormData(req);
  context.log("HTTP trigger function processed a request.");
  const name = req.query.name || (req.body && req.body.name);
  const responseMessage = {
    fields,
    files,
  };

  context.res = {
    // status: 200, /* Defaults to 200 */
    body: responseMessage,
  };
};

使用 CURL 请求客户端示例 :

curl --request POST \
  --url http://localhost:7071/api/HttpTrigger1 \
  --header 'Content-Type: multipart/form-data; boundary=---011000010111000001101001' \
  --form update=false \
  --form collection=@/Users/anzhari/masterdata/managements.json

这是客户端收到的例子:

{
  "fields": [
    {
      "fieldname": "update",
      "value": "false",
      "fieldnameTruncated": false,
      "valueTruncated": false,
      "encoding": "7bit",
      "mimetype": "text/plain"
    }
  ],
  "files": [
    {
      "fieldname": "file",
      "bufferFile": {
        "type": "Buffer",
        "data": [91, 10, ...10, 93]
      },
      "filename": "managements.json",
      "encoding": "7bit",
      "mimetype": "application/json"
    }
  ]
}

也可以通过 巴士男孩构造器配置 作为可选参数:

import { AzureFunction, Context, HttpRequest } from "@azure/functions";
import parseMultipartFormData from "@anzp/azure-function-multipart";

const httpTrigger: AzureFunction = async function (
  context: Context,
  req: HttpRequest
): Promise<void> {
  // Set the max number of non-file fields to 1 (Default: Infinity).
  const config = {
    limits: { fields: 1 },
  };
  const { fields, files } = await parseMultipartFormData(req, config);
  context.log("HTTP trigger function processed a request.");
  const name = req.query.name || (req.body && req.body.name);
  const responseMessage = {
    fields,
    files,
  };

  context.res = {
    // status: 200, /* Defaults to 200 */
    body: responseMessage,
  };
};

export default httpTrigger;
