Logging and error monitoring skills in PHP Huawei Cloud API interface docking

Introduction:
Logging and error monitoring are very important skills when docking PHP Huawei Cloud API interface. Reasonable logging can help developers quickly locate errors and troubleshoot. This article will introduce some logging and error monitoring techniques commonly used in PHP Huawei Cloud API interface docking, and provide corresponding code examples.

1. Logging skills

1. Turn on the logging function
   In PHP, turning on the logging function can be achieved by setting the php.ini file. In the php.ini file, find the following two lines of code, remove their comments, and set the log file path (such as: /path/to/logs)

   ;error_log = php_errors.log
   ;log_errors = On

2. Record error information
   First, you need to capture the error information in the code and write the error information to the log file through the error_log function. For example:

   try {
    // 执行华为云API接口请求操作
   } catch (Exception $e) {
    error_log($e->getMessage());
   }

3. Add log level
   In order to facilitate troubleshooting errors in the future, you can add log levels to the log records to classify error information at different levels. Common log levels include: debug, info, warning, error, etc. The code example is as follows:

   try {
    // 执行华为云API接口请求操作
   } catch (Exception $e) {
    error_log('[ERROR] ' . $e->getMessage());
   }

4. Record request parameters and response results
   When connecting to API interfaces, it is very important to record request parameters and response results. The request parameters and response results can be recorded in the log together. Code examples are as follows:

   try {
    // 执行华为云API接口请求操作
    $requestParams = ['param1' => 'value1', 'param2' => 'value2'];
    $response = $api->request('/api/endpoint', $requestParams);
    error_log('[INFO] Request Params: ' . json_encode($requestParams));
    error_log('[INFO] Response: ' . json_encode($response));
   } catch (Exception $e) {
    error_log('[ERROR] ' . $e->getMessage());
   }

2. Error monitoring skills

1. Use try-catch statements to capture exceptions
   When connecting to API interfaces , using try-catch statements can help developers catch exceptions and handle errors. For example:

   try {
    // 执行华为云API接口请求操作
   } catch (Exception $e) {
    // 错误处理逻辑
   }

2. Set error handler
   PHP provides the set_error_handler function, which can customize the error handler. By setting an error handler, error information can be recorded in the log and corresponding error handling can be performed. The code example is as follows:

   function errorHandler($errno, $errstr, $errfile, $errline) {
    error_log('[ERROR] ' . $errstr . ' in file ' . $errfile . ' on line ' . $errline);
   }
   
   set_error_handler('errorHandler');
   
   // 执行华为云API接口请求操作

Conclusion:
In the PHP Huawei Cloud API interface docking, logging and error monitoring skills are very important. Properly recording log information can help developers quickly locate errors and provide convenient troubleshooting. At the same time, using try-catch statements and setting error handlers can better catch exceptions and handle errors. Through the techniques introduced in this article, API interface docking can be carried out more efficiently during the development process, and the stability and reliability of the application can be improved.
