[Solved] ffmpeg Enable https Error: “ERROR: openssl not found”

ffmpeg can use libssl.so libcrypto.so dynamic library, or libssl.a libcrypto.a static library, the next is to say that obviously the inventory is there, but the compiler still can not find openssl.

Search the ffmpeg source code, and you can find that the prompt is printed in the configure file. The source code is as follows:

enabled openssl           && { use_pkg_config openssl openssl/ssl.h OPENSSL_init_ssl ||
                               check_lib openssl/ssl.h OPENSSL_init_ssl -lssl -lcrypto ||
                               use_pkg_config openssl openssl/ssl.h SSL_library_init ||
                               check_lib openssl/ssl.h SSL_library_init -lssl -lcrypto ||
                               check_lib openssl/ssl.h SSL_library_init -lssl32 -leay32 ||
                               check_lib openssl/ssl.h SSL_library_init -lssl -lcrypto -lws2_32 -lgdi32 ||
                               die "ERROR: openssl not found"; }

You can find that ffmpeg is trying OpenSSL one by one. My config The log shows that the last one has been checked, but OpenSSL is still not found.

The reason is that I am using a newer openssl library, the old openssl library uses ‘SSL_library_init’ to initialize, the newer openssl version uses ‘OPENSSL_init_ssl’ to initialize. The new version of openssl uses ‘OPENSSL_init_ssl’ to initialize, and because it does not pass the check, this error is reported here.


Add a line to check ‘check_lib openssl/ssl.h OPENSSL_init_ssl -lssl -lcrypto ‘ and it will pass, above is what I have added.

The reason for the error is that the compiling machine is running out of memory, and a large number of template extensions need enough memory.

You can solve this problem by temporarily using swap partitions:

=[step 1: operate as follows]=========================================

Sudo DD if=/dev/zero of=/swapfile bs=64m count=16
\count is the size of the increased swap space. 64M is the block size, so the space size is bs*count=1024mb
sudo mkswap /swapfile \

=[step 2: close release] ==================================================================================

Sudo swapoff /swapfile
sudo RM /swapfile
then continue to perform your relevant operations…

Note: if you still prompt “g++: internal compiler error: killed (program cc1plus)” after creating the temporary space, it may be because the allocated space is not large enough. You can continue to allocate more space.

[Solved] OpenSSL Error messages: error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure

In these two days, the service has been reporting when calling Baidu’s addressing and positioning interface and reverse address resolution:

file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages:
error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure

The query results of the interface are affected, and finally the curl call problem is solved:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_FAILONERROR, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSLVERSION, 4);
$reponse = curl_exec($ch);

CURLOPT_SSLVERSION Fetch value and meaning
CURL_SSLVERSION_TLSv1_2 requires php version >= 5.5.19
TLS 1.1 and TLS 1.2 are supported since OpenSSL 1.0.1


[Solved] “status“:405,“error“ Request method ‘POST‘ not supported“

“status“:405,“error“ Request method ‘POST‘ not supported“

Error Messages:

-“status”:405,“error”:“Method Not Allowed”,“exception”:“org.springframework.web.HttpRequestMethodNotSupportedException”,“message”:“Request method ‘POST’ not supported”



public class EmpController {

    private EmpService empService;

    public String empAdd(Model model) {
        return "emp-add";

    public String add(Emp emp, MultipartFile file){
        return "emp-add";


As it says in the Spring REST guide,

@RequestMapping maps all HTTP operations by default

but if, as they suggest, you added a specification of the allowable http methods:


then only GETs will be allowed. POSTs will be disallowed.
If you want to allow both GET and POST, but disallow all other http methods, then annotate your controller method thusly:

@RequestMapping(value = "/greeting", method = {RequestMethod.GET, RequestMethod.POST})
public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) {
    return new Greeting(counter.incrementAndGet(),
                        String.format(template, name));

When you start the application, all the request handler mappings are logged out. You should see a line like this in your log (in the IDE console or command line window):

s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/greeting],methods=[GET || POST]}" onto public hello.Greeting hello.GreetingController.greeting(java.lang.String)

[Solved] ERROR OGG-01232 Receive TCP params error: TCP/IP error 104 (Connection reset by peer), endpoint:

Solution 1:
due to the inconsistency between the ports of the source end and the destination end,
the error message of the source end is error ogg-01232 receive TCP params error: TCP/IP error 104 (connection reset by peer), endpoint:

Edit the process and view the configured ports

edit params 42P3  42P3 is the port number

The information configured in the discovery process is rmthost mgrport 7839, compress

It is inconsistent with the port reporting an error. Modify the port Edit params 42p3 to prompt port 7847. Then restart the process start 42p3

Solution 2:
after modifying the port or starting the process, it indicates that the previous port is normal (the port of the destination end is the same as that of the source end)

Just delete the line of port and write it again Edit params 42p3 , and restart start 42p3 after writing

Solution 3:
roll forward the source side delivery process to a file and generate a new file point

alter extract 42P3, etrollover

[vite] http proxy error: Error: self signed certificate in certificate chain vite

In order to prevent cross domain problems when requesting interfaces, vite proxy is used for configuration.

For example, the address of the request interface is , the vite configuration information is as follows:


server: {
        host: '',
        port: 12000,
        proxy: {
            '/local/': {
                target: '',
                changeOrigin: true,
                rewrite: (path) => path.replace(/^\/local\//, ''),


Local requests are all interfaces. You only need to add a prefix -/local /. For example, the login interface is’/local/Login ‘.

So I went to request and found that the error was reported directly. The error information is as follows:

[vite] http proxy error: Error: self signed certificate

The certificate is wrong.

Solution: add a configuration – secure: false The overall configuration code is as follows:

proxy: {
            '/local/': {
                target: '',

                // Add
                secure: false,
                // End

                changeOrigin: true,
                rewrite: (path) => path.replace(/^\/local\//, ''),

Then try again. Sure enough, there’s no problem.

[Solved] Swagger Error: Whitelabel Error Page status=405

The swagger link is accessed with the following error

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Thu Mar 17 20:14:30 CST 2022
There was an unexpected error (type=Method Not Allowed, status=405).
Request method ‘GET’ not supported

The reason is that @PostMapping does not have a configured path

    public UserInfoResponse queryUserNameById(@RequestBody UserInfoRequest request){
        log.info("Query user name request parameters",request);
        UserInfoResponse response = userService.selectUserNameById(request);
        log.info("Query user name return parameters",request);
        return response;

SpringBoot :Error parsing HTTP request header [How to Solve]

Most of these problems are container problems. There are two solutions:

1. Maybe the header cache in Tomcat is not enough

    # URI encoding of tomcat
     uri-encoding: UTF-8
     # tomcat maximum number of threads, the default is 200
     max-threads: 800
     # Tomcat starts the number of threads to initialize, the default value is 25
    min-spare-threads: 30
    max-http-form-post-size: 2MB
    max-http-header-size: 8096

2. If it hasn’t been solved

public class TomcatConfigurer {

    public TomcatServletWebServerFactory webServerFactory() {
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
        factory.addConnectorCustomizers((Connector connector) -> {
            connector.setProperty("relaxedPathChars", "\"<>[\\]^`{|}");
            connector.setProperty("relaxedQueryChars", "\"<>[\\]^`{|}");
        return factory;


[Solved] Error during WebSocket handshake Unexpected response code 404

Problem Description: the websocket project was well deployed before. When it was transplanted to the domain name specified by the government cloud SLB, an error occurred:
error during websocket handshake unexpected response code 404


1. Configure nginx

In any case, configure nginx:
proxy_http_version 1.1;
proxy_set_header Connection "upgrade";
proxy_set_header Upgrade $http_upgrade;

location /xxx{
    proxy_redirect    off;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    proxy_http_version 1.1;
    proxy_set_header Connection "upgrade";
    proxy_set_header Upgrade $http_upgrade;
    proxy_connect_timeout 60s;
    proxy_read_timeout 7200s;
    proxy_send_timeout 600s;
    # 再不行的话就把下面的设置试一下
    #proxy_set_header Upgrade websocket;
    #proxy_pass_request_headers on;
    #access_log off;
    #proxy_buffering off;

2. Websocket configuration

We use springboot, and all configurations cannot be less

import com.fh.websocket.session.MySpringConfigurator;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.server.standard.ServerEndpointExporter;

 * enable WebSocket support
public class WebSocketConfig {

	public ServerEndpointExporter serverEndpointExporter() {
		return new ServerEndpointExporter();

	public MySpringConfigurator mySpringConfigurator() {
		return new MySpringConfigurator();

3. Websocketserver needs to add a parameterless constructor

This is a pit, and it is normal to deploy to another
transplanting will not work in the past.
