1、 Enter https://curl.haxx.se/docs/caextract.html
Choose any one and download it locally
2. Edit PHP INI file
curl. Cainfo = “file address”
note the ini in the corresponding PHP version directory
III. open the SSL extension and restart the server
Add in entry file
//Allowed source domains
header("Access-Control-Allow-Origin: *");
//Allowed request header information
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept, Authorization");
//Allowed request types
header('Access-Control-Allow-Methods: GET, POST, PUT,DELETE,OPTIONS,PATCH');Hyperf uses JSON RPC and consumer to register services
Error Messages: [ERROR] Invalid protocol of registry consul[205]
Solution:
# Need to install the driver package
composer require hyperf/service-governance-consul
1. the path of session.save_path is not correct
2. session.save_path's file permissions are not correct
3. and other reasons for the error, (but mine is not the problem) this problem sent me a day of time
My mistake:
The session that occurs when using this method_set_save_handler(‘open’,‘close’,‘read’,‘write’,‘destory’,‘gc’);
reason
1. the read callback function must return the value of the string, if not, other errors will be reported
2. write callback function must return true, if false will return the above error
3. write in the insert statement of the variable value must be added to the single quotes, otherwise it can not be inserted into the database
4. all but the read callback function must return a bool value, write must return true to insert into the database, and the others I think should also return true (not tested here)
Encounter this wrong idea
1. Check the configuration file for errors first
2. then check for errors in the return value
3. then check the sql statement for errors
4. debug with echo or var_dump at each step
If you solve the big guys’ problems, please give me a favor.
Add folder mapping, domain name directory mapping (note the layer mapped to the entry file)
2. Configure hosts file
3. Reload vagrant (reload the modified configuration file)
vagrant provision&&vagrant reload
#After reloading the configuration, open vagrant
vagrant up && vagrant ssh
4. Restart nginx
service nginx restart
5. Successfully open the newly added site
\Throwable
It is the exception class that begins to appear in php7.0, and it is the parent class of \error \exception
\Error
Inherited \throwable to handle some internal errors of the system, such as memory overflow
\Exception
Inherited \throwable to handle error reports during program execution, or actively throw exceptions (\error can also throw exceptions)
1. Nginx configuration modification
1. Modify the Nginx.conf (/ etc/Nginx/Nginx.conf) configuration file, and add or modify the following configuration in http{}:
client_max_body_size 20m;
2. Restart nginx
systemctl restart nginx
2. PHP configuration modification
Find the location of the php.ini file:
Method 1
Use the command whereis php; to view the php related directories, if you can't find the ini file in the listed directories, you can refer to method 2.
Method 2
php --info > a.log;
vim a.log, To view the output, you can directly search for php.ini and you will see the directory where the file is located. As the following screenshot.
1. Modify the php.ini (/etc/PHP.ini) configuration file, find the following configuration and modify it:
post_max_size = 20M
upload_max_filesize = 20M
2. Restart PHP FPM
systemctl restart php-fpm
Error reported by thinkphp5 and wdatepicker calendar control
The solution is as follows
{literal}
<input type="text" onfocus="WdatePicker({maxDate:'#F{$dp.$D(\'logmax\')||\'%y-%M-%d\'}'})" id="logmin" class="input-text Wdate" style="width:120px;">
<input type="text" onfocus="WdatePicker({minDate:'#F{$dp.$D(\'logmin\')}',maxDate:'%y-%M-%d'})" id="logmax" class="input-text Wdate" style="width:120px;">
{/literal}
ThinkPHP uses literal to prevent template tags from being parsed
Error code:
$data=\request()->post('data');Correct practice: the data in post.data is customized in post:
$data=input('post.data/a');Error content
file_get_contents(): SSL operation failed with code 1.OpenSSL Error messages:\nerror:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed
This is related to the local environment. Whether SSL authentication is enabled
solution: modify the configuration or code
$stream_opts = [
"ssl" => [
"verify_peer"=>false,
"verify_peer_name"=>false,
]
];
$response = file_get_contents($url, false, stream_context_create($stream_opts));
Problem recurrence:
<?php
function getCertInfo($domain)
{
$context = stream_context_create([
'ssl' => [
'capture_peer_cert' => true,
'capture_peer_cert_chain' => true,
],
]);
$client = stream_socket_client("ssl://{$domain}:443", $errorCode, $errorMessage, 30, STREAM_CLIENT_CONNECT, $context);
if ($client === false) {
var_dump("!!!open {$domain} socket connection fail. {$errorMessage}($errorCode) !!!";
return false;
}
$params = stream_context_get_params($client);
if (empty($params['options']['ssl']['peer_certificate'])) {
var_dump("!!!{$domain} stream_context_get_params options ssl peer_certificate is empty!!!");
return false;
}
return openssl_x509_parse($params['options']['ssl']['peer_certificate']);
}
Solution: $context add verify_ Peer configuration
<?php
$context = stream_context_create([
'ssl' => [
'capture_peer_cert' => true,
'capture_peer_cert_chain' => true,
'verify_peer' => false,
],
]);
