Get raw buffer of nodejs request

weidox · May 11, 2021, 10:48am

Is it possible to read raw json as buffer from node request (ctx.req)? I need to validate signature, so parsed variant coming from Strapi does not fit. I’m trying with body-parser library, it seems to work but in the end nothing gets being read (did some debugging). Could it be that stream is already at the end and cannot be read again, or some other issue?

**Describe the bug** I am trying to obtain the raw request body to I can verify it using Stripe's library. This question was previously asked #4720, but the solution the user posted no longer seems to work. **Steps to reproduce the behavior** 1. Create a `config/env/**/request.json` with the following content: ```json { "parser": { "enabled": true, "multipart": true, "includeUnparsed": true } } ``` 2. Import the `unparsed` symbol helper from `koa-body` ```js const unparsed = require('koa-body/unparsed.js'); ``` 3. Attempt to access the unparsed body. ```js async index(ctx) { const unparsedBody = ctx.request.body[unparsed]; console.log(unparsedBody) // undefined } ``` **Expected behavior** I would have received the unparsed body. **Screenshots** N/A **Code snippets** config/env/development/request.json ```json { "parser": { "enabled": true, "multipart": true, "includeUnparsed": true } } ``` api/test/controllers/test.js ```js "use strict"; const unparsed = require("koa-body/unparsed.js"); module.exports = { async test(ctx) { console.log("\n==== Environment ======================="); console.log(`NODE_ENV=${process.env.NODE_ENV}`); console.log("\n==== Requests Config ==================="); console.log(strapi.config.request); console.log("\n==== Unparsed Symbol ==================="); console.log(unparsed); console.log("\n==== Unparsed Body ====================="); console.log(ctx.request.body[unparsed]); console.log(""); return {}; }, }; ``` Output: ``` ==== Environment ======================= NODE_ENV=development ==== Requests Config =================== { parser: { enabled: true, multipart: true, includeUnparsed: true } } ==== Unparsed Symbol =================== Symbol(unparsedBody) ==== Unparsed Body ===================== undefined ``` **System** - Node.js version: 12.16.1 - NPM version: 6.13.4 (Yarn 1.22.4) - Strapi version: 3.0.1 - Database: PostgreSQL - Operating system: macOS 10.15.5

For Strapi 4:

// config/middleware.js
module.exports = [
  'strapi::errors',
  'strapi::security',
	'strapi::cors',
  'strapi::poweredBy',
  'strapi::logger',
  'strapi::query',
  {
    name: 'strapi::body',
    config: {
      patchKoa: true,
      multipart: true,
      includeUnparsed: true,
    },
  },
  'strapi::session',
  'strapi::favicon',
  'strapi::public',
];

To get raw data:

const unparsed = require("koa-body/unparsed.js");
const rawData = ctx.request.body[unparsed]
