我目前正在使用WSClient发布文件到终点,用下面的代码用java
public Result uploadBankingFile(){
logger.info("Uploading file to cold fusion");
MultipartFormData<File> body = request().body().asMultipartFormData();
MultipartFormData.FilePart<File> bankingFile = body.getFile("bankingFile");
if (bankingFile != null) {
String fileName = bankingFile.getFilename();
String contentType = bankingFile.getContentType();
//field needs to be called import
Source<ByteString, ?> file = FileIO.fromFile(bankingFile.getFile());
MultipartFormData.FilePart<Source<ByteString, ?>> fp = new MultipartFormData.FilePart<>("import", fileName, "text/plain", file);
MultipartFormData.DataPart dp = new MultipartFormData.DataPart("key", "value");
Future<WSResponse> post = ws.url(coldFusionPath + coldFusionUploadPath).post(Source.from(Arrays.asList(fp,dp)));
return new JsonResult("ok");
} else {
flash("error", "Missing file");
return badRequest();
}
}
我使用的框架版本2.5.15,并与Java 8发布MultipartFormData与WSClient 。我得到的问题是
