图片上传的 Java API

[xingchenxuup]

之前的版本 Image image = group.uploadImage(new URL(“url地址”));

现在的版本？Image image = group.uploadImage(new ExternalImage(new DeferredReusableInput()));
我没搞明白啊 有人能解答下吗

ExternalImageJvmKt.toExternalImage(???)
详细用例可见：https://github.com/sandtechnology/DantuiHelper/blob/0f84a5e36841b29bfc264ed6a996cd1ac67b5ab2/src/main/java/sandtechnology/holder/WriteOnlyMessage.java#L189
当然你可以传inputstream，见IDE提示

自 2.0-M2-dev-11:

@NotNull
private <T> T magic() {
    throw new RuntimeException();
}

ExternalResource resource = magic();

public void externalResource() throws IOException {
    resource.inputStream();


    contact.uploadImage(resource); // base method


    ExternalResource r;

    r = ExternalResource.create((InputStream) magic()); // throws IOException
    r = ExternalResource.create((File) magic());
    r = ExternalResource.create((RandomAccessFile) magic());

    ExternalResource.uploadAsImage(r, contact);  // returns Image

    ExternalResource.sendAsImage(r, contact);    // returns MessageReceipt


    ExternalResource.uploadAsImage((ExternalResource) magic(), contact);    // returns Image
    ExternalResource.uploadAsImage((File) magic(), contact);                // returns Image
    ExternalResource.uploadAsImage((InputStream) magic(), contact);         // returns Image

    ExternalResource.sendAsImage((ExternalResource) magic(), contact);  // returns MessageReceipt
    ExternalResource.sendAsImage((File) magic(), contact);              // returns MessageReceipt
    ExternalResource.sendAsImage((InputStream) magic(), contact);       // returns MessageReceipt

    Contact.uploadImage(contact, (ExternalResource) magic());   // returns Image
    Contact.uploadImage(contact, (File) magic());               // returns Image
    Contact.uploadImage(contact, (InputStream) magic());        // returns Image

    Contact.sendImage(contact, (ExternalResource) magic());     // returns MessageReceipt
    Contact.sendImage(contact, (File) magic());                 // returns MessageReceipt
    Contact.sendImage(contact, (InputStream) magic());          // returns MessageReceipt

    // experimental
    ExternalResource.uploadAsGroupVoice(magic(), (Group) contact);
}
