最简单的测试发票pdf是否正常的方式：
打开微信发票助手，选择这个pdf文件，能导入成功就是正常的，不能就说明pdf有问题
你好，麻烦通过点击下方“反馈信息”按钮，提供出现问题的。

public static String uploadPdfFile(String accessToken, File file) {
HttpPost httpPost = new HttpPost("https://api.weixin.qq.com/card/invoice/platform/setpdf?access_token=" + accessToken);
CloseableHttpResponse response = null;
CloseableHttpClient httpClient = HttpClients.createDefault();
RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(5000).setConnectTimeout(5000).build();
httpPost.setConfig(requestConfig);
HttpEntity httpEntity = MultipartEntityBuilder.create().addPart("pdf", new FileBody(file, ContentType.create("multipart/form-data", Consts.UTF_8), file.getName())).build();
httpPost.setEntity(httpEntity);
try {
response = httpClient.execute(httpPost, new BasicHttpContext());
log.info("上传PDF文件至微信返回参数：{}", JSON.toJSONString(response));
if (response.getStatusLine().getStatusCode() != 200) {
log.info("上传PDF文件至微信，请求失败");
}
HttpEntity entity = response.getEntity();
if (entity != null) {
String resultStr = EntityUtils.toString(entity, "utf-8");
log.info("上传PDF文件至微信返回参数：{}", resultStr);
JSONObject result = JSON.parseObject(resultStr);
int errcode = (Integer)result.get("errcode");
if (errcode != 0) {
log.info("上传PDF文件至微信失败");
return result.getString("s_media_id");
} catch (IOException e) {
e.printStackTrace();
} finally {
if (response != null)
response.close();
return null;
