如何从MultipartFormData获取DataPart？我找不到任何 API 来实现这一点。

Http.MultipartFormData formData = body.asMultipartFormData(); 
 
// simple form field 
// there is NO getData() or something available 
DataPart imageIdPart = formData.getData("dataKey"); 
 
// uploaded file 
FilePart imagePart = formData.getFile("imageKey"); 

请您参考如下方法:

我不习惯在 Play 2.0 中使用 Java，但是类似的东西可以工作吗？

@BodyParser.Of(BodyParser.MultipartFormData.class) 
public static Result index() { 
    Http.MultipartFormData multipartFormData = request().body().asMultipartFormData(); 
 
    //ask the multipart to be form url encoded...  
    //and get the data 
    String[] data = multipartFormData.asFormUrlEncoded().get("dataKey"); 
 
    //which should not impact such call 
    Http.MultipartFormData.FilePart image = multipartFormData.getFile("imageKey"); 
 
    return ok("Got image: " + image.getFilename()); 
}
