问题描述
我正在尝试使用 Graph API 版本 2.3.2 发送带有多个附件的邮件(大小总和小于 4MB).请找到以下相同的代码片段.
I'm trying to send mail with multiple attachments (Sum of size is < 4MB) using Graph API version 2.3.2. Please find the following code snippet for the same.
public static void main(String[] a){
try {
TestBase testBase = new TestBase();
Message message = getMessage();
message.hasAttachments = true;
AttachmentCollectionResponse response = new AttachmentCollectionResponse();
response.value = Arrays.asList(
getFileAttachment("/home/user/Downloads/3MBPDF.pdf"),
getFileAttachment("/home/user/Downloads/20KBPDF.pdf"));
message.attachments = new AttachmentCollectionPage(response, null);
testBase.graphClient.me().sendMail(message, true).buildRequest().post();
}catch (Exception e){
e.printStackTrace();
}
}
private static Message getMessage() {
Message message = new Message();
java.util.List<String> emails = Arrays.asList("vivektest@gmail.com");
java.util.List<Recipient> listReceipient = new ArrayList<>();
for(String email : emails) {
EmailAddress emailAddress = new EmailAddress();
emailAddress.address = email;
Recipient recipient = new Recipient();
recipient.emailAddress = emailAddress;
listReceipient.add(recipient);
}
message.body = getItemBody();
message.toRecipients = listReceipient;
message.subject = "Test Message";
message.id = "1234";
return message;
}
private static ItemBody getItemBody() {
ItemBody itemBody = new ItemBody();
itemBody.content = "<html><head></head><body> test body </body></html>";
itemBody.contentType = BodyType.HTML;
return itemBody;
}
private static FileAttachment getFileAttachment(String path) throws Exception{
FileAttachment fileAttachment = new FileAttachment();
File pdfFile = new File(path);
InputStream fileStream = new FileInputStream(pdfFile);
fileAttachment.name = pdfFile.getName();
fileAttachment.contentBytes = getByteArray(fileStream);
fileAttachment.oDataType = "#microsoft.graph.fileAttachment";
fileAttachment.size = Math.toIntExact((pdfFile.length() / 1024) / 1024);
System.out.println("FileSize::: "+fileAttachment.size);
fileAttachment.id="521";
return fileAttachment;
}
public static byte[] getByteArray(InputStream in) {
try {
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
int nRead;
byte[] data = new byte[16384];
while ((nRead = in.read(data, 0, data.length)) != -1) {
buffer.write(data, 0, nRead);
}
buffer.flush();
return buffer.toByteArray();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
我已经仔细检查了文件的大小.3MBPDF.pdf = 3.6 MB20KBPDF.pdf = 20 KB
I've double check the size of the files. 3MBPDF.pdf = 3.6 MB 20KBPDF.pdf = 20 KB
总大小不大于 4 MB 但仍然返回以下错误
Total size is not greater then 4 MB but still its returning following error
严重:可投掷细节:com.microsoft.graph.http.GraphServiceException:错误代码:BadRequest错误信息:支持的最大请求长度为 4MB.

上面的代码片段是我从 msgraph-sdk-java 存储库的测试用例中捕获的.
The above code snippet I've captured from the test case of msgraph-sdk-java repo.
请帮助我发送小于 4 MB 的电子邮件.谢谢
Please help me to send email with size less then 4 MB. Thanks
推荐答案
您的请求超出了 Graph 请求的最大 4MB 限制:
Your request is exceeding the maximum 4MB limit for Graph requests as:
- 第一个 pdf:3.6MB
- 空间使用量增加为第一基于 base64 编码的 PDF:2.2MB
- 第二个 pdf:20kB
- 第二个 PDF 的空间使用量增加:7kB
- JSON 有效负载:可能只有几 kB
- 1st pdf :3.6MB
- space usage increase for 1st PDF due to base64 encoding : 2.2MB
- 2nd pdf: 20kB
- space usage increase for 2nd PDF: 7kB
- JSON payload: probably a few kBs
总数远远超过 4MB 的限制.您需要使用 大型附件上传那个PDF.
the total being well over the 4MB limit. You need to use large attachment uploads for that PDF.
