在 MultipartEntityBuilder 中编码文件名 [英] Encode filename in MultipartEntityBuilder

问题描述

我正在尝试使用 HttpPost 和 MultipartEntityBuilder 的文件上传 API.以下是我使用过的代码.

I am trying a file upload API using HttpPost and MultipartEntityBuilder. Following is the code I have used.

MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setCharset(MIME.UTF8_CHARSET);
builder.addBinaryBody(<fileFieldName>, <byteArray>, ContentType.TEXT_PLAIN, <fileName>);

文件已正确上传.但是当文件名包含非 ASCII 字符时，它会以名称????.jpg"上传.尝试了此处给出的解决方案 https://stackoverflow.com/a/25870301/3271472.但这并没有解决我的问题.请协助.

File gets uploaded correctly. But when file name contains non-ASCII characters, it gets uploaded with name "????.jpg". Tried the solution given here https://stackoverflow.com/a/25870301/3271472. But it didn't solve my problem. Please assist.

推荐答案

这对我有用:

MultipartEntityBuilder b = MultipartEntityBuilder.create();
b.addPart("file", new FileBody(<FILE>, <CONTENTTYPE>, <FILENAME>)).setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
b.setCharset(StandardCharsets.UTF_8);

只需将 <> 值替换为您的值...

Just replace <> values with yours...
