The client noticed that the server is not a supported distribution of Elasticsearch
我尝试升级@elastic/elasticsearch到最新版本^7.14.0，但这并没有解决问题。
AWS 配置也没有发生任何变化，导致此错误的原因是什么？
请指教。
我最近升级到 Node 10，运行时npm install出现以下错误：

const char* str1 = "david";
char* str2 = const_cast<char *> (str1);
str2 = "tna";
现在str2的值发生了变化,但是str1的原始值保持不变,我在谷歌上查了一下,却找不到明确的答案.
当使用const_cast并更改值时,const变量的原始值是否也会发生变化？
我正在使用这个npm包:https://www.npmjs.com/package/soap
我在文档中找不到答案,因为我想知道SOAP客户端的最佳实践是创建单个客户端作为启动并用于所有请求(类似于数据库客户端),还是为每个请求创建一个新客户端.
我正在进行团结游戏并遇到一个我无法解决的问题.我通过标准的WWW对象连接到Web服务器并使用协程来执行POST请求.
代码本身可以工作,但是我需要更新变量值并在协程完成后返回该变量,这是我无法做到的.
public int POST(string username, string passw)
{
WWWForm form = new WWWForm();
form.AddField("usr", username);
form.AddField("pass", passw);
WWW www = new WWW(url, form);
StartCoroutine(WaitForRequest(www));
//problem is here !
return success_fail;
}
private IEnumerator WaitForRequest(WWW www)
{
yield return www;
if (www.error == null)
{
if(www.text.Contains("user exists"))
{
success_fail = 2;
}
else
{
success_fail=1;
}
} else {
success_fail=0;
}
}
协程使用相关值更新'success_fail'的值.但'返回success_fail;' POST方法中的行在协同程序完成之前运行,这会导致它返回false值.
我试图使用额外的协程,但没有成功,假设我也有错误.如何在协程完成后返回'success_fail'值？
谢谢.
我想知道在C++中是否有任何相对容易和短的日期比较函数.我的日期是类型char*,并具有以下格式:DD\MM\YYYY
谢谢.
我正在编写单元测试并模拟包“child_process”中的“exec”方法。

const child_process = jest.genMockFromModule('child_process');
child_process.exec = jest.fn()

const defaultArguments = () => {
return {
