我正在将我的Android应用程序中的视频文件和其他一些数据发送到运行Play框架应用程序的服务器,我正在使用multipartEntity
Volley
和parse
来将Post请求发送到服务器。
我需要multipartEntity
我的控制器中收到的private static final String FILE_PART_NAME = "fileKey";
public MultipartRequest(String url, File file, Map<String, String> mStringPart,
Response.Listener<String> listener,
Response.ErrorListener errorListener)
super(Method.POST, url, errorListener);
mListener = listener;
mFilePart = file;
this.mStringPart = mStringPart;
entity.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
buildMultipartEntity();
}
private void buildMultipartEntity() {
entity.addPart(FILE_PART_NAME, new FileBody(mFilePart));
for (Map.Entry<String, String> entry : mStringPart.entrySet()) {
entity.addTextBody(entry.getKey(), entry.getValue());
}
}
@Override
public byte[] getBody() throws AuthFailureError {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
try {
httpentity = entity.build();
httpentity.writeTo(bos);
} catch (IOException e) {
VolleyLog.e("IOException writing to ByteArrayOutputStream");
}
return bos.toByteArray();
}
请求,并将视频存储在服务器上的文件夹中,并将其余数据发送到mySQL数据库。
MultipartRequest:
public static Result uploadFile(){
RequestBody body = request().body();
Http.MultipartFormData multippartBody = body.asMultipartFormData();
if(multippartBody != null) {
return ok("Got: " + "Hi");
}
else {
return badRequest("Expecting text/plain request body");
}
}
到目前为止,这是我的控制器:
multippartBody
我认为我需要某种迭代器来从public static Result jsonPost(){
RequestBody body = request().body();
Http.MultipartFormData multippartBody = body.asMultipartFormData();
Http.MultipartFormData.FilePart imageFile = body.getFile(fileKey);
if(multippartBody != null) {
return ok("Got: " + "hi");
}
else {
return badRequest("Expecting text/plain request body");
}
}
}
中提取视频和其他数据,但我不确定如何实现这一点
修改
更新了控制器:
public static Result jsonPost(){
RequestBody body = request().body();
Http.MultipartFormData multippartBody = body.asMultipartFormData();
Http.MultipartFormData.FilePart imageFile = multippartBody.getFile("fileKey");
if(imageFile.getFile() != null) {
File file = imageFile.getFile();
String fileName = imageFile.getFilename();
File newDir = new File("/public/images/","MyApp");
if(!newDir.isDirectory()){
newDir.mkdirs();
System.out.println("Created dir");
}
if(newDir.canWrite()){
file.renameTo(new File(newDir, fileName));
}
return ok("Got: " + "it");
}
else {
return badRequest("Expecting text/plain request body");
}
}
我从fileKey上的Play中找不到符号错误?
修改让它正常工作

检查请求标头中的内容类型,如果是application / octet-stream use
File file = request().body().asRaw().asFile();
如果是multipart / form-data类型使用
play.mvc.Http.MultipartFormData body = request().body().asMultipartFormData();
play.mvc.Http.MultipartFormData.FilePart imageFile = body.getFile(imageKey);
File file = imageFile.getFile();
