我将上传图片到arweave存储在solana上,但是每次都会遇到错误。我现在有1.2索尔,并且知道它足够上传图片。错误如下。

我们如何从node.js获取ip地址我尝试了很多方法,但都不起作用并返回::ffff:127.0.0.1请给我一些建议
这是我的代码:
app.put('/update-user-info', function(req, res){
// it's doesn't work and return ::ffff:127.0.0.1
var ip = req.headers['x-forwarded-for'] || req.connection.remoteAddress || req.socket.remoteAddress || re
我正试图通过猫鼬驱动程序连接到我的mongodb Atlas,它一直抛出一个MongooseServerSelectionError,并且我已经为数据库用户检查了我的用户名和密码,这是正确的。
这是我的代码:

当我运行npm run dev -- -H 192.168.1.100时,我得到了这个错误 { Error: listen EADDRNOTAVAIL: address not available 192.168.1.100:3000

当我从一个可靠的智能合约中调用一个仅查看函数时,我在web3js中得到了一个错误。奇怪的是,它可以在本地testnet上运行(通过Ganache运行),然而,当我将契约部署到ropsten测试网络时,fall函数失败,并显示以下错误:
Uncaught (in promise) Error: Returned values aren't valid, did it run Out of Gas?
at i.decodeParameters (web3.min.js:22508)

我正在尝试从node.js/Express中在猫鼬模式中创建一个子文档。
我有两个模式:成员和地址
Member.js
// app/models/member.js
// load mongoose since we need it to define a model
var mongoose = require('mongoose'),
Schema = mongoose.Schema
var Address = require('./address');
var MemberSchema = Schema({
FName : String,
我已经迁移数据两天了,在AWS上一切正常--我用的是Bitnami MEAN机器,它只是一个很小的应用程序。仅供参考,我正在从Heroku + Parse迁移,在AWS上设置nginx以运行多个nodejs应用程序。由于与Parse不兼容,我不得不降级默认的mongodb安装(为什么?)
所以,直截了当地说:安装了node.js解析服务器,配置就像它们在git上显示的那样
var api = new ParseServer({
databaseURI: 'mongodb://127.0.0.1:27017/database',

我使用的是web3库版本0.20.2。我想要对我的智能合约做的就是传输定制的erc20令牌。
下面的智能合约代码(懒惰)
function transfer(address _to, uint256 _value) returns (bool success) {}
我想使用此函数将我的自定义令牌传输到_to (地址)。
var myContract = web3.eth.contract(abi)
var myContractInstance = myContract.at(address);
var total = myContractInstance.totalSupply();
