有谁知道使用改造 2 将图像上传到服务器的方法。大多数在线解决方案都使用改造 1。
谢谢 我试过这个:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//GALLERY
if ((isGalleryCalled(requestCode) && resultCode == RESULT_OK)) {
Log.w(TAG, "onActivityResult > isGalleryCalled > data.getData(): " + data.getData());
Uri originalUri = data.getData();
if (originalUri != null) {
mImageUri = originalUri;
}
}
//CAPTURE
else if ((isCaptureCalled(requestCode)) && resultCode == RESULT_OK) {
Log.w(TAG, "onActivityResult > isCaptureCalled > data.getData(): " + data.getData());
Uri originalUri = data.getData();
if (originalUri != null) {
mImageUri = originalUri;
}
}
private void prepareImage(String mImageUri ) {
File file = new File(mImageUri );
mRequestBodyImage = RequestBody.create(MediaType.parse("multipart/form-data"), file);
isUploadImage = true;
Log.d(TAG, "isUploadImage: " + isUploadImage + " | \nuri: " + uri + " | \nfile getPath: " + file.getPath());
}//end sendReport
Call<DefaultResponse> call = RestClient.get().uploadImage(file);
....
@Multipart
@POST(Constant.API_UPLOADIMAGE)
Call<DefaultResponse> uploadImage(
//Upload File
@Part("myfile\"; filename=\"image.png\" ") RequestBody file
);
我收到这些错误:
sendErrorReport - file: com.squareup.okhttp.RequestBody$3@2f83a2f9
stat failed: ENOENT (No such file or directory) : content:/media/external/images/media/2720
java.io.FileNotFoundException: content:/media/external/images/media/2720: open failed: ENOENT (No such file or directory)

[更新]
Update code from feed back from @Anton Shkurenko
图像路径开始处理
UtilApiHelp.getPath:/storage/emulated/0/DCIM/Camera/20151210_124246.jpg
private void prepareImage(String uri) {
File file = new File(uri);
mRequestBodyImage = RequestBody.create(MediaType.parse("multipart/form-data"), file);
isUploadImage = true;
Log.d(TAG, "prepareImage isUploadImage: " + isUploadImage + " | \nuri: " + uri + " | \nfile getPath: " + file.getPath());
sendErrorReport("", mRequestBodyImage);// test1
uploadImage(file.getPath());//test 2
}//end sendReport
//API Send Image test 1 - FAILED
private void sendErrorReport(String s, String msg, RequestBody file){
Log.e(TAG, "sendErrorReport - file: " + file.toString());
String user_id = Preferences.getInstance().getUserId();
Call<DefaultResponse> call = RestClient.get().sendErrorReport(s, file);
call.enqueue(new Callback<DefaultResponse>() {
@Override
public void onResponse(Response<DefaultResponse> response, Retrofit retrofit) {
Log.w("sendErrorLog > onResponse => ", String.valueOf(response.isSuccess()));
}
@Override
public void onFailure(Throwable t) {
t.printStackTrace();
}
});
}
error: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 3 column 2 path $
//Upload test 2 -> not working
private void uploadImage(final String path) {
final RequestBody photo =
UtilApiHelp.getImageBodyBuilder(new HashMap<String, String>() {{
put("image", path);
}})
//.addFormDataPart("here_you_can_add_another_form_data", anotherFormData)
.build();
Call<DefaultResponse> call = RestClient.get().sendErrorReport(photo);
call.enqueue(new Callback<DefaultResponse>() {
@Override
public void onResponse(Response<DefaultResponse> response, Retrofit retrofit) {
}
@Override
public void onFailure(Throwable t) {
t.printStackTrace();
}
});
}
Error: Caused by: java.lang.IllegalArgumentException: @Body parameters cannot be used with form or multi-part encoding. (parameter #1) for method APIService.sendErrorReport
使用了这个电话
@FormUrlEncoded
@POST(Constant.API_POST_error_log)
Call<DefaultResponse> sendErrorReport(@Body RequestBody multipartBody);
最佳答案
[更新]
由于您更新了问题。您只是无法从给定的 Uri 中找到文件。使用我的代码中的 util 函数 getPath
获取图像路径,希望这会起作用。
[旧解决方案]
我有这个可行的解决方案:
实用函数:
public static RequestBody getImageBody(Map<String, String> map) {
return getImageBodyBuilder(map).build();
}
public static MultipartBuilder getImageBodyBuilder(Map<String, String> map) {
MultipartBuilder builder = new MultipartBuilder().type(MultipartBuilder.FORM);
for (String key : map.keySet()) {
final String filePlace = map.get(key);
Log.d(TAG, "File place: " + filePlace);
final String[] args = filePlace.split("\\.");
final String fileExt = args[args.length - 1];
Log.d(TAG, "File extension: " + fileExt);
// Old solution, porting from one project to another
// It's about problems with jpeg
builder.addPart(Headers.of("Content-Disposition",
"form-data; name=\"" + key + "\"; filename=\"" + filePlace + "\""), RequestBody.create(
MediaType.parse("image/" + fileExt.toLowerCase().replace("jpg", "jpeg")),
new File(map.get(key))));
}
return builder;
}
public static String getPath(Context ctx, Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = ctx.getContentResolver().query(uri, projection, null, null, null);
if (cursor == null) return null;
int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String s = cursor.getString(columnIndex);
cursor.close();
return s;
}
照片上传。
final RequestBody photo =
ImageUploadUtils.getImageBodyBuilder(new HashMap<String, String>() {{
put("photo", imagePathWhateverYouWant);
}})
.addFormDataPart("here_you_can_add_another_form_data", anotherFormData).build();
mApiService.attachPhoto("Token " + getToken(), photo);
ApiService.java(接口(interface)):
// I user here RxJava, but I think it's easy to use Calls here.
@POST("deliveries/photos") Observable<Map<String, String>> attachPhoto(
@Header("Authorization") String token,
@Body RequestBody multipartBody);
关于android - 如何使用 Retrofit2 将照片上传到服务器,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/34175313/
