Curl HTTPS returned errno 35 (SSL connect error) error

CURL HTTPS returns the ERRNO 35(SSL CONNECT ERROR) ERROR
WeChat payments occasionally fail to get a prepay id.
WeChat pay will be asked to get prepay from WeChat server id (https://api.mch.weixin.qq.com/pay/unifiedorder). After we finished the development (the language is PHP, using WeChat’s payment SDK, and using curl to make requests), on the machine in the test environment, we found almost no failure of requests, but after we went online, we found frequent errors, with a probability of 1/5 or even higher. At the beginning, I did not delve into the reasons and tried again. However, I found that as long as I failed, I would fail again.
The curl error recorded is: errno:35, error: SSL Connect Error.
Search relevant information online, did not find a solution. Contact WeChat technical support, they have no Suggestions, think it is our problem, let us check by ourselves.

php mysqli_ connect_ Error () and mysqli_ connect_ The difference of errno() function

First let’s look at the official definition:

Grammatical definitions:
Definition:
> Mysqli_connect_error () : The function returns an error description of the last connection error.
> Mysqli_connect_errno () : The function returns the error code for the last connection error.

Note: One returns an error description and the other an error code.

Uncaught Error: Script error for ” popper.js “, needed by: bootstrap solution 

Uncaught Error: Script error for "popper.js", needed by: bootstrap
https://requirejs.org/docs/errors.html#scripterror
    at makeError (require.js:168)
    at HTMLScriptElement.onScriptError (require.js:1738)

This error is caused by Bootstrap’s dependence on the popper.js component. Bootstrap relies on jQuery or some plug-ins that depend on popper.js.
I found a solution online.

require(["popper"], function(popper) {
    // set popper as required by Bootstrap
    window.Popper = popper;
    require(["bootstrap"], function(bootstrap) {
        // do nothing - just let Bootstrap initialise itself
    });
});

Try it, the problem is still unsolved.
Then start with bootstrap.
The previous code in bootstrap looks like this.

(function (global, factory) {
  typeof exports === 'object' && typeof module !== 'undefined' ?factory(exports, require('popper.js'), require('jquery')) :
  typeof define === 'function' && define.amd ?define(['exports', 'popper.js', 'jquery'], factory) :
  (factory((global.bootstrap = {}),global.Popper,global.jQuery));
}(this, (function (exports,Popper,$) { 'use strict';

Manually change the configuration in RequireJS to require Paths instead of popper.js. My configuration looks like this.

'popper':                 'popper.js/dist/umd/popper.min',

Therefore, directly change the first few lines of bootstrap source code popper.js to popper to solve the problem.
 
However, I think it is inappropriate to change the source code in this way. So he looked for a solution.
 
The ultimate solution is this.

require.config({
  baseUrl: '/vendors',
  paths: {
    'jquery':                 'jquery/dist/jquery.min',
    'bootstrap':              'bootstrap/dist/js/bootstrap',
    'popper':                 'popper.js/dist/umd/popper.min',
    ...
  },
  shim: {
    'bootstrap': ['jquery']
  },
  map: {
    '*': {
      'popper.js': 'popper'
    }
  }
});

The core solution is:

Add a map configuration in the configuration of require

‘popper.js’: ‘popper’
 
And then I met,
Datatables.net – BS4 relies on datatables.net as well.
Add a row to the map to configure:
‘datatables.net’: ‘datatables’

Busybox encountered input/output error while mounting NFS to TMP file system

Error is as follows
Mount -T NFS 192.168.1.83:/home/ WRR/TMP/WRR
< 4> svc: failed to register lockdv1 RPC service (errno 111).
< 4> lockd_up: makesock failed, error=-111

If I add nolock it will just return. But later copy file card dead. But it’s a little too much.

Then,
The mount -t NFS 192.168.1.83:/home/WRR/web/TMP/WRR
& lt; 4> SVC: failed to register lockdv1 RPC service (110) errno.
the mount: mounting 192.168.1.83:/home/WRR/web on/TMP/WRR failed: Connection timed out

Maybe this error is related to Nfs server permissions, so add the no_root_squard parameter to the server. To continue. There’s still a mistake.

Because the NFS server factor is excluded, then mount is fine (because it’s a little copier). So this is a story that has nothing to do with servers and mounts.

See on the English post (http://forums.xilinx.com/t5/Embedded-Linux/nfs-mount-problem-on-microblaze/td-p/153272)
Something is not running on the Busybox file system. Some additional parameters need to be added.
The mount -o port = 2049, nolock, proto = TCP -t NFS 192.168.103.83:/home/WRR/web/TMP/WRR
It worked. The magic parameters are in port and proto= TCP. The exact cause is unknown.

SCRIPT1002: syntax error File: 0. chunk.js ,SCRIPT5009: ‘Map‘ is undefined File: 0. chunk.js -Solutions

Scene description

The React project starts with NPM run start and works fine in Chrome, Firefox, and Edge, but when Internet explorer opens, the console reports an error with the title
The solution

1.SCRIPT1002: syntax error File: 0. Chunk. Js, Line: 2296, Column: 27
SRC /index.js
add the following and put it on the first line

import 'react-app-polyfill/ie9';
import 'react-app-ployfill/stable;'
import 'fast-text-encoding/text';

Json
find browserslist and add ie9 which is the above support

"browserslist" {
	"production": [
		...,
		"ie>9",
	],
	"development": [
		...
		"ie>9",
	]
},

First, ensure the above module, if not, you can execute NPM install to install
After the module is installed, Internet Explorer opens the project again and the problem is resolved. But then the following problem arises…
2.SCRIPT5022: SyntaxError File: 1. chunk.js, Line: 197681, Column: 38
The error in the Internet Explorer console, the solution:
Open the /node_modules/react - dev - utils/webpackHotDevClient js , in the following code to add slashes: true,

then,
goes into the node_moudles folder, delete all contents of the . Cache folder, and clear the cache in Internet explorer.
SCRIPT5009: 'Map' is File: Map is undefined e.chunk.js, Line: 2340,0 Column: 3
I did not solve this error by myself. Due to the company project, NPM install cannot be run on the server's Intranet. Therefore, I provide ideas and hope you can solve it perfectly.
Official advice: https://reactjs.org/docs/javascript-environment-requirements.html
calculate, this has not been solved, sorry...

Unable to open the physical file “d:\***.mdf”. Operating system error 5: “5(Access is denied.)”.

SQL SERVER2008 is installed under Windows 7. An error occurred trying to attach an existing database MDF file,
Unable to open the physical file “d:\***.mdf”. Operating system error 5: “5(Access is denied.)”.
Is to set the SQL Server related account access to the file
Let Management Studio run as an administrator
 

SQL Server 2008 login 4064 error solution

This error is caused by the account being unable to open the default database
Change the default open database for this account.
If, unfortunately, your SA account and Windows authentication are both open to the same database by default, logging in either way is equally useless
If you have an account that you can log in to, just right click on the security – login username property and change the default database to master.
If you cannot log in either way, modify the default database for the SA by following the command below
If you’re unlucky enough to forget your SA password and you can only log in with Windows authentication, and you don’t happen to know the Windows login name,
Ga can only try to find out what the Windows identity login name is
The combination is probably the computer name \Administrator. Run the following command with CMD to change the default open database for an account, sql2005 version below, and change SQLCMD to ISQL
sqlcmd -E -d”master” -Q”exec sp_defaultdb N’sa’, N’master'”

Runtime error r6016 problem

The introduction
Life is like a play, every day in the mistakes, but I have been too deep into the play, all the mistakes will be solved.
The problem

I didn’t know what I ordered today, and then the computer reported a mistake, as shown in the picture below:

Originally thought to ignore it, hurriedly do other things, then think a problem can not compromise ah, if not immediately solved, may cause a bigger problem. So, let’s see how I solved it!
To solve
1. Open control panel

2. Programs — Enable or disable Windows functions

3. Remove the check mark in front of WindowsMedia Player.

conclusion

We are not afraid of small problems, but we are afraid of dragging. No matter how small the problem is, we can’t put up with it. Just like the human body, we don’t care about small problems. Therefore, the teacher teaches us will not be the source power of discovery!!
