Use PHP to write programs to connect to Baidu Cloud Disk API

Baidu Cloud Disk is a powerful cloud storage service that can realize many automated operations through the API. For example, upload files, download files, create folders, etc. This article will introduce how to use PHP to write a program to connect to Baidu Cloud Disk API, and give corresponding code examples.

1. Get Baidu Cloud’s developer account and API Key

Before using Baidu Cloud Disk API, we need to apply for a developer account first and obtain the corresponding API Key. You can log in to Baidu Cloud Open Platform (https://developer.baidu.com/) to apply and obtain.

2. Configuring the PHP development environment

First, make sure you have installed the PHP development environment. Then open the configuration file php.ini of your PHP development environment, find and uncomment the following two lines in the file to enable cURL extension and JSON extension:

;extension=php_curl.dll
extension =php_json.dll

Save and exit the configuration file, and restart the PHP development environment to take effect.

3. Write PHP code

Next, we start writing PHP code to connect to Baidu Cloud Disk API. The following takes uploading files as an example and gives corresponding code examples:

// Baidu Cloud API Key and Secret Key
$apiKey = 'your_api_key';
$secretKey = 'your_secret_key';

// Request URL
$url = 'https://pan.baidu.com/rest/2.0/xpan/file?method=upload&access_token=';

// Get access_token
$accessToken = getAccessToken($apiKey, $secretKey);

// The file path to be uploaded
$filePath = 'path/to/your /file';

// File name
$fileName = basename($filePath);

// Establish cURL connection
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url.$accessToken);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
'filename' => $fileName ,
'path' => '/',
'ondup' => 'overwrite',
'file' => '@'.$filePath
));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

//Execute the request and get the return Result
$response = curl_exec($ch);
curl_close($ch);

// Parse return result
$result = json_decode($response, true);

//Print upload result
if ($result && isset($result['error_code']) && $result['error_code'] == 0) {
echo 'File uploaded successfully! ';
} else {
echo 'File upload failed! ';
}

//Get access_token function
function getAccessToken($apiKey, $secretKey) {
$url = 'https://openapi.baidu.com/oauth/2.0 /token';
$data = array(

'grant_type' => 'client_credentials',
'client_id' => $apiKey,
'client_secret' => $secretKey

);

// Establish cURL connection
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

//Execute the request and get the return result
$response = curl_exec($ch) ;
curl_close($ch);

// Parse return result
$result = json_decode($response, true);

// Return access_token
return $ result['access_token'];
}
?>

First of all in the code, we define the Baidu Cloud API Key and Secret Key. Then, obtain the access_token through the getAccessToken function. This access_token will be used for subsequent requests to the Baidu Cloud Disk API.

Next, we specify the relevant parameters of the uploaded file, including file path, file name, upload path, etc. Establish a cURL connection, submit these parameters through POST, execute the request, and obtain the return result.

Finally, we parse the returned results, determine whether the file is uploaded successfully, and print the corresponding prompt.

4. Run the program

Save the above code as an upload.php file, and replace 'your_api_key' and 'your_secret_key' with your own API Key and Secret Key. Then execute the following command in the command line window:

php upload.php

If everything goes well, you will see a successful upload message in the command line window.
