ipfs.cat(cid) in node js gives error "Error: Invalid version, must be a number equal to 1 or 0 at Function.validateCID"

Question

我正在使用 ipfs-http-client 模块。

This is my script

async function main() {

const ipfs_client = require('ipfs-http-client');
const client = ipfs_client({recursive: false});


async function addFile(file_data) {
    const cid = function (data) {

        return client.add(data).then(cid =>{return cid;}).catch(err=>{
            console.log(err)})
    }
    const real_cid = cid(file_data).then(result=>{return result}).catch(err=>{console.log(err)});
    return real_cid;
}

const sendFileToNet = async (file) => {
    return await addFile(file);
}
async function getFile(cid){

//error occurs here
    for await (const chunk of client.cat(cid)) {
        console.info(chunk)
    }
    return content;
}

const getFileFromNet = async()=>{
    return await getFile();
}
getFileFromNet("QmU77sHBUuCT12324e9Re59bNHekpKg1PdCpiVAj3MFLiH").then(r => console.log(r));
module.exports = {sendFileToNet, getFileFromNet

};

}

main();

您的 getFile 函数接受一个参数。您在 getFileFromNet 中调用它但没有传递参数。
