在将文件上传到IPFS后生成密钥时出错

Question

我得到了一个错误，而生成密钥后，上传文件到IPFS格式。

下面提供的示例代码

var ipfsAPI = require('ipfs-http-client');
const ipfs = ipfsAPI('ipfs.infura.io', '5001', { protocol: 'https' });
var oldpath = files[property].path;
var uploadedFile = fs.readFileSync(oldpath);
const filess = [{
                    path: files[property].name,
                    content: ipfs.types.Buffer.from(uploadedFile)
             }];
 ipfs.add(filess, function (err, files) {

                  if (err || !files) {
                        return reject('upload failed');
                    };
 var obj;
for (i = 0; i < data.length; i++) {
    obj = { "id": i, "hash": data[i], "EID": formFields.EID };
    tt.push(obj);
}
ipfs.dag.put(tt, {}, (err, cid) => {
    console.log(cid.toBaseEncodedString());
    const adr = cid.toBaseEncodedString();
    var dTimeStamp = new Date().getTime();
ipfs.key.gen(dTimeStamp, {
type: 'rsa',
size: 2048
}, (err, key) => {
    if (err != null) {
        console.log(err)
        }

    console.log("ipfs Key: ", key.id + " key name : " + key.name);

    var keyVall = key.id;


ipfs.name.publish(adr, { key: keyVall }, (err, pVal) => {


        console.log("published hash : " + pVal);

        var ipfsHash = pVal.name;


    return resp.json({ status: 'SUCCESS', message: 'user has been created successfully', digitalID: pVal });
});
});
});

});

在生成密钥时，我得到了一个以下错误

"SyntaxError: Unexpected token < in JSON at position 0
    at JSON.parse (<anonymous>)
    at streamToValue (C:\Service\node_modules\ipfs-http-client\src\utils\stream-to-json-value.js:25:18)

任何线索都将不胜感激。

Infura服务只允许通过其网关提供一小部分IPFS方法，因此您不能通过ipfs.key.gen生成密钥

我建议运行您自己的IPFS节点，特别是如果您想生成和存储密钥区。
