PDF 插入

使用 PDF 插入工具，您可以根据需要插入 PDF 文件。以下示例展示了如何上传测试 PDF 文件并在第 1 页前面插入两个 PDF 页面（高度为 800，宽度为 500），使用 Java、PHP、C#、Python 和 Swift 语言。

Java

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

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

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

// File handling parameter settings
CPDFPageInsertParameter fileParameter = new CPDFPageInsertParameter();
fileParameter.setTargetPage("1");
fileParameter.setWidth("500");
fileParameter.setHeight("800");
fileParameter.setNumber("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 insert task
$taskInfo = $client->createTask(CPDFDocumentEditor::INSERT);

// File handling parameter settings
$file = $client->addFile('test.pdf')
    ->setTargetPage('1')
    ->setWidth('500')
    ->setHeight('800')
    ->setNumber('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 insert task
CPDFCreateTaskResult result = client.CreateTask(CPDFDocumentEditorEnum.INSERT);

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

// File handling parameter settings
CPDFPageInsertParameter fileParameter = new CPDFPageInsertParameter();

fileParameter.TargetPage = "1";
fileParameter.Width = "500";
fileParameter.Height = "800";
fileParameter.Number = "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 insert task
create_task_result = client.create_task(CPDFDocumentEditorEnum.INSERT)

# Get a task id
task_id = create_task_result.task_id

# File handling parameter settings
file_parameter = CPDFPageInsertParameter()

file_parameter.target_page = "1"
file_parameter.width = "500"
file_parameter.height = "800"
file_parameter.number = "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 insert task
    let taskModel = await client.createTask(url: CPDFDocumentEditor.INSERT)
    
    // 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: "",params: [
        CPDFFileUploadParameterKey.targetPage.string() : "2",
        CPDFFileUploadParameterKey.width.string() : "500",
        CPDFFileUploadParameterKey.height.string() : "800",
        CPDFFileUploadParameterKey.number.string() : "2"
    ], taskId: taskId)
    
    // Execute task
    let _ = await client.processFiles(taskId: taskId)
    
    // Query TaskInfo
    let taskInfoModel = await client.getTaskInfo(taskId: taskId)
}

所需参数：

• targetPage：页码。

• width：页面宽度（默认 595）。

• height：页面高度（默认 842）。

• number：要插入的页数（默认 1）。

结果：

文件类型	说明
.pdf	插入页面后的 PDF 文件。
