在IPFS.ADD（）方法中使用带有EJS的IPF在上传文件中获取错误

发布于 2025-02-12 17:51:04 字数 10942 浏览 0 评论 0原文

我正在尝试使用EJS应用将文件上传到IPF。我遇到了很多发布的问题，但是我还没有看到像我遇到的问题。

当我们使用简单的字符串“ Hello World” 使用ipfs.add（）方法时，它仍然适用于其他人，但就我而言，它会丢弃错误。

这是我尝试上传文件的代码：

上传文件代码（upload.ejs）：

<div class="card">
            <h5 class="card-header">Upload Document to IPFS</h5>
            <div class="card-body">
                <form action="/ipfs" method="POST" enctype="multipart/form-data">
                    <div class="row">
                        <div class="form-group col-10">
                            <input type="file" name="filetoupload" class="form-control">
                        </div>
                        <div class="form-group col">
                            <button type="submit" class="btn btn-primary">UPLOAD</button>
                        </div>
                    </div>
                </form>
            </div>
        </div>

app.js file：

const fs = require('fs')
const express = require("express");
const cors = require('cors');
const path = require('path');
const fileupload = require('express-fileupload');
const { create } = require("ipfs-http-client");

const app = express();

app.use(fileupload());
app.use(cors());
app.use(express.static(path.join(__dirname,'public')));
app.use(express.json());
app.use(express.urlencoded({ extended: true }));

app.set('views', './views');
app.set('view engine', 'ejs');

app.listen(8010, () => {
  console.log("Application started and Listening on port 8010");
});

app.get("/", (req, res) => {
  res.render("home");
});


const ipfs = create({host:'localhost',port:6001,protocol:'http'});
app.get("/ipfs/:hashcode", async function(req, res) {
    const hashcode = req.params.hashcode;
    res.setHeader('Content-Type','application/json');
    let result = false;
    if (hashcode) {
        const stream = ipfs.cat(hashcode);
        let data = ''

        for await (const chunk of stream) {
        // chunks of data are returned as a Buffer, convert it back to a string
        data += chunk.toString()
        }
        result = true;
        res.json({
            'success': result,
            'data': data
        });

            
        
    } else {
        res.json({
            'success': result,
            'data': ''
        });
    }
  
});

app.post("/ipfs", (req, res) => {
    
    const file = req.files.filetoupload;
    const filename = req.files.filetoupload.name;

    console.log("here")
    const filepath = 'files/' + filename;

    file.mv(filepath, async(err) => {
        if(err){
            console.log("ERROR: Upload File Error!");
            return res.status(500).send(err);
        }
        const hashcode = await addFile(filename,filepath);
        console.log("HHHHAAAAAAAAAAAAAAAAAAASSSSSSSSSSSSHHHHHH...."+hashcode); // here i am gettin undefined
        fs.unlink(filepath, (err  => {
            if(err) console.log(err);
        }))
        res.render("upload",{filename, hashcode});
    })
    
    
});
// ipfs api: https://github.com/ipfs/js-ipfs/blob/master/docs/core-api/FILES.md#ipfsadddata-options
const addFile = async(filename,filepath) => {

    try {
        const file = fs.readFileSync(filepath);
        console.log("------------------(Here Before await)--------------------\n");
        // const added = await ipfs.add(file);
        // const added = await ipfs.add({path: filename, content:file});
        const added = await ipfs.add("hello world"); // here i am getting error
        console.log("------------------(Here After await)--------------------\n"); // after error this lone is ignored
        // console.info(added);
        return added.cid.toString();
    } catch (err){
        console.log(err);
    }
    
}

我在应用程序中使用addfile（）方法。

​

version: '3'
services:
  ipfs:
    image: ipfs/go-ipfs:latest
    container_name: ipfs_host
    volumes:
      - ./export:/export

    ports:

      - '127.0.0.1:8080:8080'
      - '127.0.0.1:7010:7010'

​ 在提出@discordian的建议后，更新了错误快照 @discordian跟踪我没有Docker-Compose，但是之后我仍会遇到错误。

I am trying to upload a file to ipfs using ejs app. I have go to a lot of posted problems but i have not seen a problem like i am getting.

when we use ipfs.add() method with a simple string "Hello World" it still worked for others but in my case it is throwing an error.

This is the code where I try to upload the file:

upload file code (upload.ejs):

<div class="card">
            <h5 class="card-header">Upload Document to IPFS</h5>
            <div class="card-body">
                <form action="/ipfs" method="POST" enctype="multipart/form-data">
                    <div class="row">
                        <div class="form-group col-10">
                            <input type="file" name="filetoupload" class="form-control">
                        </div>
                        <div class="form-group col">
                            <button type="submit" class="btn btn-primary">UPLOAD</button>
                        </div>
                    </div>
                </form>
            </div>
        </div>

app.js file:

        });

            
        
    } else {

        return added.cid.toString();
    } catch (err){
        console.log(err);
    }
    
}

I am getting in addFile() method in app.js const added = await ipfs.add("hello world");

Error Snap (Updated):
The error snap is updated after some suggestion of @discordian
@discordian trace that i have no docker-compose, but after that i am still getting the error.
