我先用前端form上传表单数据（包含上传文件）到后台服务器，在后台服务器中可以提出TempFile
然后在后台程序中通过如下类上传图片到指定文件服务器
public static NutMap Upload(String token,String userId,String type, TempFile tempFile){
try {
Request req = Request.create("http://127.0.0.1:8182/upload/image/user/" + userId, Request.METHOD.POST);
File f = File.createTempFile("shuxin", "data");
Files.write(f, tempFile.getInputStream());
req.getParams().put(type, f);
req.getParams().put("token", token);
FilePostSender sender = new FilePostSender(req);
Response resp = sender.send();
String json = resp.getContent();
Result result = Json.fromJson(Result.class, json);
if (result.success()) {
List<NutMap> list = (List<NutMap>) result.getData();
if (list != null && list.size() > 0) {
return list.get(0);
} else {
throw Lang.makeThrow("未知错误");
}
} else {
throw Lang.makeThrow(result.getMsg());
}
}
catch(IOException ex){
throw Lang.makeThrow(ex.getMessage());
}
}
文件服务器（采用NB搭建）接收端口为：
文件服务器直接通过前端表单上传是没有问题的
@AdaptBy(type = UploadAdaptor.class, args = {"ioc:imageUpload"})
@At(value = {"/image/?/?"})
@Ok("json")
public Object images(String type, String name, @Param("image") TempFile[] files, @Param("..")NutMap data, HttpServletRequest req, AdaptorErrorContext err) {
try {
if (err != null && err.getAdaptorErr() != null) {
return Result.error("文件不合法:" + err.toString());
} else {
return Helper.upload(type,name,files,data,"image");
}
} catch (Throwable e) {
return Result.error(e.getMessage());
}
}
提交后，文件服务器报错如下：
