進行POST呼叫

下一步是使用必要的參數對端點進行HTTPPOST呼叫。 模板和資料檔案作為資源檔案提供。 生成的pdf的屬性是通過請求中選項的參數指定的。屬性embedFonts用於在生成的pdf中嵌入自定義字型。請依照本檔案,將自訂字型部署至您的Forms雲端執行個體。 屬性在options.json資源檔案中指定。 因此,端點具有代號式驗證,我們會在要求標題中傳遞存取代號。

以下程式碼是透過將資料與範本合併而產生pdf

public class DocumentGeneration
{
        public String SAVE_LOCATION = "c:\\aspire1";
        public void mergeDataWithXdpTemplate(String postURL)
        {
                HttpPost httpPost = new HttpPost(postURL);
                CredentialUtilites cu = new CredentialUtilites();
                String accessToken = cu.getAccessToken();
                httpPost.addHeader("Authorization", "Bearer " + accessToken);
                ClassLoader classLoader = DocumentGeneration.class.getClassLoader();
                URL templateFile = classLoader.getResource("templates/custom_fonts.xdp");
                File xdpTemplate = new File(templateFile.getPath());
                URL url = classLoader.getResource("datafiles");
                System.out.println(url.getPath());
                File files[] = new File(url.getPath()).listFiles();
                for (int i = 0; i < files.length; i++) {
                        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
                        ContentType strContent = ContentType.create("text/plain", Charset.forName("UTF-8"));
                        builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
                        builder.addBinaryBody("data", files[i]);
                        builder.addBinaryBody("template", xdpTemplate);
                        builder.addBinaryBody("options",GetOptions.getPDFOptions().getBytes(),ContentType.APPLICATION_JSON,"options"
                        try {
                                HttpEntity entity = builder.build();
                                httpPost.setEntity(entity);
                                CloseableHttpClient httpclient = HttpClients.createDefault();
                                CloseableHttpResponse response = httpclient.execute(httpPost);
                                InputStream generatedPDF = response.getEntity().getContent();
                                byte[] bytes = IOUtils.toByteArray(generatedPDF);
                                File saveLocation = new File(SAVE_LOCATION);
                                if (!saveLocation.exists()) {
                                        saveLocation.mkdirs();
                                }
                                File outputFile = new File(SAVE_LOCATION+File.separator+files[i].getName().replace("xml", "pdf"));
                                try (FileOutputStream outputStream = new FileOutputStream(outputFile)) {
                                        outputStream.write(bytes);
                                }
                        } catch (Exception e) {
                                System.out.println("The error is " + e.getMessage());
                        }

                }
                System.out.println("Done generating " + files.length + " files");

        }
