我正在尝试上传文件以及JSON
帖子正文。我试过这样的事情:
requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("data", uploadFileName[1], RequestBody.create(MEDIA_TYPE_JPEG, file))
.addFormDataPart("name", uploadFileName[1])
.addFormDataPart("body",postBody)
.build();
注意:如果我想通过删除上传没有帖子的文件,上面的代码可以工作
.addFormDataPart("body",postBody)
我也尝试创建文件和帖子体的ByteOutputArray并尝试创建一个ResquestBody
。
像这样的东西:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
baos.write((boundaryStr).getBytes("UTF-8"));
baos.write(("Content-Disposition: attachment;filename=\"" + uploadFileName + "\"\r\n").getBytes("UTF-8"));
baos.write(("Content-Type: application/octet-stream\r\n\r\n").getBytes("UTF-8"));
byte[] buffer = new byte[102400];// 100KB
int read = imageInputStream.read(buffer);
while (read >= 0) {
baos.write(buffer);
read = imageInputStream.read(buffer);
}
baos.write(("\r\n").getBytes("UTF-8"));
baos.write((boundaryStr).getBytes("UTF-8"));
baos.write(("Content-Disposition: attachment; name=\"" + fileNameText + "\"\r\n\r\n").getBytes("UTF-8"));
baos.write((postData).getBytes("UTF-8"));
baos.write(("\r\n").getBytes("UTF-8"));
baos.write(("--" + boundary + "--\r\n").getBytes("UTF-8"));
baos.flush();
MediaType MEDIA_TYPE_JPEG = MediaType.parse(fileType);
RequestBody requestBody = RequestBody.create(MEDIA_TYPE_JPEG,baos.toByteArray());
但没有任何工作。请帮忙。
提前致谢
请尝试以下代码:
private void chooseImageFile(){
Intent intent = new Intent() ;
intent.setType("image/*") ;
intent.setAction(Intent.ACTION_GET_CONTENT) ;
startActivityForResult(Intent.createChooser(intent, "Select Image"), PICK_IMAGE_REQUEST);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null){
Uri imagepath = data.getData() ;
try {
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), imagepath) ;
uploadimage.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
}
private String getStringImage(Bitmap bitmap){
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream() ;
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOutputStream) ;
byte[] imagebyte = byteArrayOutputStream.toByteArray() ;
String encodeString = Base64.encodeToString(imagebyte, Base64.DEFAULT) ;
return encodeString ;
}
private void callImageUpload() {
String image_name = imagename.getText().toString().trim() ;
String bitmap_string = getStringImage(bitmap) ;
OkHttpClient image_upload_client = new OkHttpClient() ;
RequestBody postbody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("image", bitmap_string)
.addFormDataPart("name", image_name)
.build() ;
Request request = new Request.Builder().url(url).post(postbody).build() ;
setProgressDialouge();
image_upload_client.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
}
@Override
public void onResponse(Call call, Response response) throws IOException {
progressDialog.dismiss();
String json_string = response.body().string() ;
try {
JSONObject main_obj = new JSONObject(json_string);
final String msg = main_obj.getString("response");
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
}
});
}
catch (JSONException e) {
e.printStackTrace();
}
}
});
}
@Multipart
@POST("/api/index.php?tag=sendFile")
Call<Object> sendCurrentFileAPI(
@Part("file") RequestBody designation, @Part MultipartBody.Part file);
我正在使用以下方法在我的Activity中上传文件
MultipartBody.Part multipartBody = null;
try {
RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), uploadingCurrentFile);
multipartBody = MultipartBody.Part.createFormData("file", uploadingCurrentFile.getName(), requestFile);
} catch (Exception e) {
e.printStackTrace();
}
RequestBody requestBody = RequestBody.create(MediaType.parse("text/plain"), requestBody +"");
mService.sendCurrentFileAPI( selectedDesignationValueRequestBody, multipartBody).enqueue(new Callback<Object>() {
@Override
public void onResponse(@NonNull Call<Object> call, @NonNull Response<Object> response) {
if (response.isSuccessful()) {
}
@Override
public void onFailure(@NonNull Call<Object> call, @NonNull Throwable t) {
}
});
