[FIXED] compoer not found Swagger class for get api in php file

Issue

I had to use the Swagger-php package to use an api and I installed this package in the composer service and it was included in the composer.json file, but when using the methods This package gives me an class ... not found error, the first time I encounter this problem and I could not find a useful answer through Google search.

Note: I installed this package in the same way as the previous packages and all packages respond to each other (composer require [package name])

• Error text:

Fatal error: Uncaught Error: Class "Swagger\Client\Configuration" not found ...

• Things I did:

1 - I update composer

2 - I insert package repository to composer.json

,"repositories": [
        {
            "type": "vcs",
            "url":  "git@bitbucket.org:vendor/my-private-repo.git"
        }
    ]

3 - composer dumpautoload and composer run

• idont change psr4,because I did not know how to do it

my code:

<?php
require_once("/home/milad/vendor/autoload.php");

// Configure API key authorization: apieco-key
Swagger\Client\Configuration::getDefaultConfiguration()->setApiKey('7UHoMOuKT0bgYv0FmG9xFi70d11DVP0C', 'YOUR_API_KEY');
// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
// Swagger\Client\Configuration::getDefaultConfiguration()->setApiKeyPrefix('apieco-key', 'Bearer');

$api_instance = new Swagger\Client\Api\ConditionsApi();
$apiecoKey = "7UHoMOuKT0bgYv0FmG9xFi70d11DVP0C"; // String | 
$age = "40"; // String | age
$enableTriage5 = true; // Boolean | enable 5-level triage values

try {
    $result = $api_instance->conditions($apiecoKey, $age, $enableTriage5);
    print_r($result);
} catch (Exception $e) {
    echo 'Exception when calling ConditionsApi->conditions: ', $e->getMessage(), PHP_EOL;
}
?>

Solution

According to your composer.json, you are using zircote/swagger-php in v3. The code you are using looks like something that is not compatible with v3, as the maintainers changed their namespace from Swagger to OpenApi

You either need to follow a tutorial that is made for v3, or downgrade the package you are using to v2
