PDF 删除

使用 PDF 删除工具，您可以根据需要删除 PDF 文件。以下示例展示了如何使用 Java、PHP、C#、Python 和 Swift 语言上传测试 PDF 文件并删除 PDF 第 1~2 页。然后输出没有第 1 页和第 2 页的 PDF 文件。

Java

// Create a client
CPDFClient client = new CPDFClient(publicKey,secretKey);

// Create a task
// Create an example of a PDF delete task
CPDFCreateTaskResult result = client.createTask(CPDFDocumentEditorEnum.DELETE);

// Get a task id
String taskId = result.getTaskId();

// File handling parameter settings
CPDFPageDeleteParameter fileParameter = new CPDFPageDeleteParameter();
fileParameter.setPageOptions(Arrays.asList("1","2"));

// Upload files
client.uploadFile(new File("test.pdf"), taskId, fileParameter);

// Execute task
client.executeTask(taskId);

// Query TaskInfo
CPDFTaskInfoResult taskInfo = client.getTaskInfo(taskId);

PHP

// Create a client
$client = new CPDFClient('public_key', 'secret_key');

// Create a task
// Create an example of a PDF delete task
$taskInfo = $client->createTask(CPDFDocumentEditor::DELETE);

// File handling parameter settings
$file = $client->addFile('test.pdf')
    ->setPageOptions(['1', '2']);

// Upload files
$fileInfo = $file->uploadFile($taskInfo['taskId']);

// Execute task
$client->executeTask($taskInfo['taskId']);

// Query TaskInfo
$taskInfo = $client->getTaskInfo($taskInfo['taskId']);

C#

// Create a client
CPDFClient client = new CPDFClient(publicKey,secretKey);

// Create a task
// Create an example of a PDF delete task
CPDFCreateTaskResult result = client.CreateTask(CPDFDocumentEditorEnum.DELETE);

// Get a task id
string taskId = result.TaskId;

// File handling parameter settings
CPDFPageDeleteParameter fileParameter = new CPDFPageDeleteParameter();
fileParameter.PageOptions = new List<string>() { "1", "2" };

// Upload files
client.UploadFile(new FileInfo("test.pdf"), taskId, fileParameter);

// Execute task
client.ExecuteTask(taskId);

// Query TaskInfo
CPDFTaskInfoResult taskInfo = client.GetTaskInfo(taskId);

Python

# Create a client
client = CPDFClient(public_key, secret_key)

# Create a task
# Create an example of a PDF delete task
create_task_result = client.create_task(CPDFDocumentEditorEnum.DELETE)

# Get a task id
task_id = create_task_result.task_id

# File handling parameter settings
file_parameter = CPDFPageDeleteParameter()

file_parameter.page_options = ["1", "2"]

# Upload files
client.upload_file('test.pdf', task_id, file_parameter)

# Execute task
client.execute_task(task_id)

# Query TaskInfo
task_info = client.get_task_info(task_id)

Swift

// Create a client
let client: CPDFClient = CPDFClient(publicKey: public_key, secretKey: secret_key)

Task { @MainActor in
    // Create a task
    // Create an example of a PDF delete task
    let taskModel = await client.createTask(url: CPDFDocumentEditor.DELETE, language: .english)
    
    // Get a task id
    let taskId = taskModel?.taskId ?? ""

    // Upload files
    let path = Bundle.main.path(forResource: "test", ofType: "pdf")
    let uploadFileModel = await client.uploadFile(filepath: path ?? "", password: "", language: .english, params: [CPDFFileUploadParameterKey.pageOptions.string():["1"]], taskId: taskId)
    
    // Execute task
    let _ = await client.processFiles(taskId: taskId, language: .english)
    
    // Query TaskInfo
    let taskInfoModel = await client.getTaskInfo(taskId: taskId, language: .english)
}

所需参数：

• pageOptions：删除文档的页面范围，页码从1开始（输入的页码必须大于0，且不能超过文档的最大页码）。以下是删除部分页面范围的示例：1,2,5-10。您可以在此处看到所有已删除的页面：第1、2、5、6、7、8、9、10页。

结果：
