通过 Go SDK 按名称解析 PDF 以提取文本

    package main

import (
	"encoding/json"
	"fmt"
	"os"
	"path"

	asposepdfcloud "github.com/aspose-pdf-cloud/aspose-pdf-cloud-go/v25"
)

// Extract text box form the document
func ParseExtractTextBox(documentName string, textboxName string, localFolder string, remoteFolder string) {
	// Get your AppSecret and Key from https://dashboard.aspose.cloud (free registration required).
	pdf_api := asposepdfcloud.NewPdfApiService(APP_SID, APP_KEY, "")

	args := map[string]interface{}{
		"folder": remoteFolder,
	}

	file, _ := os.Open(path.Join(localFolder, documentName))	
	_, _, _ = pdf_api.UploadFile(path.Join(remoteFolder, documentName), file, args)

	result, httpResponse, err := pdf_api.GetTextBoxField(documentName, textboxName, args)
	if err != nil {
		fmt.Println(err.Error())
	} else if httpResponse.StatusCode < 200 || httpResponse.StatusCode > 299 {
