Java 如何使用ConvertAPI将HTML字符串转换为PDF（无物理文件）
以前我使用的是Java 如何使用ConvertAPI将HTML字符串转换为PDF（无物理文件）,java,c#,convertapi,Java,C#,Convertapi,以前我使用的是http://do.convertapi.com/Web2Pdf使用Java通过简单的GET请求（而不是POST）将HTML字符串转换为PDF。使用curl参数传递整个内容 然而，该API最近似乎已经停止工作。我正在尝试转移到https://v2.convertapi.com/web/to/pdf但是我找不到一个使用GET或POST的新API来实现相同功能的示例 有人能提供一个使用Java发出GET或POST请求的示例吗 更新：我已经设法使它工作 private static fi

private static final String WEB2PDF_API_URL = "https://v2.convertapi.com/html/to/pdf";
private static final String WEB2PDF_SECRET = "secret-here";
String htmlContent = "valid HTML content here";
URL apiUrl = new URL(WEB2PDF_API_URL + "?secret=" + WEB2PDF_SECRET + "&download= attachment&PageOrientation=landscape&MarginLeft=0&MarginRight=0&MarginTop=0&MarginBottom=0");
HttpURLConnection connection = null;
ByteArrayOutputStream buffer = null;
connection = (HttpURLConnection) apiUrl.openConnection();
connection.setRequestProperty("Content-Disposition", "attachment; filename=\"data.html\"");
connection.setRequestProperty("Content-Type", "application/octet-stream");
connection.setRequestMethod("POST");
connection.setConnectTimeout(60000);
connection.setReadTimeout(60000);
connection.setDoOutput(true);
/* write request */
OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());
writer.write(htmlContent);
writer.flush();
writer.close();
/* read response */
String responseMessage = connection.getResponseMessage();
logger.info("responseMessage: " + responseMessage);
int statusCode = connection.getResponseCode();
logger.info("statusCode: " + statusCode);
if (statusCode == HttpURLConnection.HTTP_OK) {
logger.info("HTTP status code OK");
// parse output
InputStream is = connection.getInputStream();
buffer = new ByteArrayOutputStream();
int nRead;
byte[] data = new byte[16384];
while ((nRead = is.read(data, 0, data.length)) != -1) {
buffer.write(data, 0, nRead);
}
buffer.flush();
byte[] attachmentData = buffer.toByteArray();
Multipart content = new MimeMultipart();
...
MimeBodyPart attachment = new MimeBodyPart();
InputStream attachmentDataStream = new ByteArrayInputStream(attachmentData);
attachment.setFileName("filename-" + Long.toHexString(Double.doubleToLongBits(Math.random())) + ".pdf");
attachment.setContent(attachmentDataStream, "application/pdf");
content.addBodyPart(attachment);

}
您可以轻松地将HTML字符串作为文件推送。我没有JAVA示例，但C#演示将为您提供正确的路径
