java 如何将文件上传到 SOAP Web 服务？

How to upload a file to a SOAP web service?

提问by Kalina

I have a .p12 file that I want to upload to a SOAP web service, so that my application can make requests to get it later. How do I upload this file?

我有一个 .p12 文件，我想将其上传到 SOAP Web 服务，以便我的应用程序可以在以后发出请求以获取它。我如何上传这个文件？

I don't necessarily want this in my application code, since it's something I only want to do once. But, if it matters, I am using Java.

我不一定希望在我的应用程序代码中使用它，因为这是我只想做一次的事情。但是，如果重要的话，我正在使用 Java。

You should take a look at MTOM, if the service supports it. If it accepts file attachments, then it probably uses MTOM. Not sure what you mean by keeping it out of application code, but how you go about creating and sending an attachment depends on what web service platform you're using. Here's the latest documentation on sending attachments in Java's JAX-WS:

如果服务支持，您应该查看 MTOM。如果它接受文件附件，则它可能使用 MTOM。不确定将它保留在应用程序代码之外是什么意思，但是如何创建和发送附件取决于您使用的 Web 服务平台。这是有关在 Java 的 JAX-WS 中发送附件的最新文档：

If you want to see what is actually happening in a language-independent manner, then grab SoapUI and set it up to send your attachment with MTOM:

如果您想以独立于语言的方式查看实际发生的情况，请获取 SoapUI 并将其设置为使用 MTOM 发送您的附件：

At server side send encode string and Base64.decode file string

在服务器端发送编码字符串和 Base64.decode 文件字符串

String strAttachmentCoded = "";
private int PICK_PDF_REQUEST = 1;
Uri filePath;

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == PICK_PDF_REQUEST && resultCode == Activity.RESULT_OK && data != null && data.getData() != null) {
        filePath = data.getData();
        File uploadFile = new File(filePath.toString());
        URI uri = URI.create(uploadFile.getPath());
        try {
            if (uploadFile != null) {
                File uploadFile1 = new File(uri);

                ByteArrayOutputStream objByteArrayOS = new ByteArrayOutputStream();

Read the file as an stream and send it over the wire. That's all.

将文件作为流读取并通过网络发送。就这样。
