我刚刚在Windows上创建了我的第一个应用程序.

我该如何给它一个图标？

似乎没有任何构建标志来执行此操作,我知道golang不支持资源.

How do I connect to Amazon's new DocumentBD database from node.js (In this case, using an out-of-the-box Elastic Beanstalk setup.)

This is my code, copied from the docs (with some values altered for privacy). It just times out and the eventual value of 'err' is 'true'. What did I miss? How can I get a better error?

var MongoClient = require('mongodb').MongoClient,fs = require('fs');
var ca = [fs.readFileSync("rds-combined-ca-bundle.pem")];
var connection_string = "mongodb://USERNAME:PASSWORD@docdb-2019-04-23-12-55-44.cluster-abcdefghij.eu-west-1.docdb.amazonaws.com:27017/?ssl=true&&replicaSet=rs0&readPreference=secondaryPreferred";

MongoClient.connect(
        connection_string, {
            sslValidate: true,
            sslCA: ca,
            useNewUrlParser: true …

我正在尝试为golang中的所有结构创建一个基础对象.出于某种原因,当我创建的新对象位于不同的包中时,我无法使其工作.它们在同一个包/文件夹中时工作正常.

例如,所有对象的基类

package Test

type BaseObject struct {
    base interface{}
}

----子文件夹测试\东西---

创建一个新的TestObject,它是BaseObject的子类

package Stuff

import Test "Test"

type TestObject struct{
    Test.BaseObject
}
func (this *TestObject)DoSomething(){
    any reference to this.base or this.BaseObject.base fails!!!
}

---在同一个文件夹中,everthing工程---

package Test

type TestObject struct{
    BaseObject
}
func (this *TestObject)DoSomething(){
    any reference to this.base works fine??
}
