進行POST呼叫
下一步是使用必要的引數向端點進行HTTPPOST呼叫。 範本和資料檔會以資源檔的形式提供。 產生的pdf屬性是透過請求中的選項引數指定。embedFonts屬性是用來在產生的pdf中嵌入自訂字型。請依照此檔案將自訂字型部署至您的Forms雲端執行個體。屬性是在options.json資源檔案中指定的。 由於端點具有權杖型驗證，因此我們會在請求標頭中傳遞存取權杖。
下列程式碼是用來將資料與範本合併，以產生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");
}
}
