注意點：

方案一中：map.put(“files\”; filename=\”” + file.getName(), requestBody);

方案二中：builder.addFormDataPart(“files”, file.getName(), imageBody)；

需與服務器一制,如：Content-Disposition: form-data; name=”files”; filename=”1.jpg”)

方案一：

@Multipart

@POST("upload/v1/images")

Observable> uploadImages(@Header("token") String token, @Part("appkey") RequestBody appkey, @Part("sign") RequestBody sign,

@PartMap() Mapmap);

/**

* 上傳

* @param compressFile 需要上傳的文件

*/

private void upload(ListcompressFile) {

LogUtil.e(TAG, "uploadImages: 開始上傳...");

//多張圖片

Mapmap = new HashMap<>();

if (compressFile != null && !compressFile.isEmpty()) {

for (int i = 0; i < compressFile.size(); i++) {

File file = compressFile.get(i);

LogUtil.e(TAG, "upload: path: " + file.getAbsolutePath());

RequestBody requestBody = RequestBody.create(MediaType.parse("multipart/form-data"), file);

map.put("files\"; filename=\"" + file.getName(), requestBody);

}

}

RequestBody appkey = RequestBody.create(null, Api.APPKEY);

RequestBody sign = RequestBody.create(null, Api.SIGN);

mApiWrapper.uploadImages(appkey, sign, map)

.subscribeOn(Schedulers.io())

.observeOn(AndroidSchedulers.mainThread())

.subscribe(new Observer() {

@Override

public void onSubscribe(@NonNull Disposable d) {

}

@Override

public void onNext(@NonNull Object t) {

LogUtil.e(TAG, "uploadImages: 上傳成功");

}

@Override

public void onError(@NonNull Throwable e) {

}

@Override

public void onComplete() {

}

});

}

方案二：

@Multipart

@POST("upload/v1/images")

Observable> uploadImages1(@Header("token") String token, @Part ListpartList);

/**

* 上傳

* @param compressFile 需要上傳的文件

*/

private void upload(ListcompressFile) {

LogUtil.e(TAG, "uploadImages: 開始上傳...");

//多張圖片

MultipartBody.Builder builder = new MultipartBody.Builder()

.setType(MultipartBody.FORM)//表單類型

.addFormDataPart("appkey", Api.APPKEY)

.addFormDataPart("sign", Api.SIGN);

for (int i = 0; i < compressFile.size(); i++) {

File file = compressFile.get(i);

RequestBody imageBody = RequestBody.create(MediaType.parse("multipart/form-data"), file);

builder.addFormDataPart("files", file.getName(), imageBody);

}

Listparts = builder.build().parts();

mApiWrapper.uploadImages(parts)

.subscribeOn(Schedulers.io())

.observeOn(AndroidSchedulers.mainThread())

.subscribe(new Observer() {

@Override

public void onSubscribe(@NonNull Disposable d) {

}

@Override

public void onNext(@NonNull Object t) {

LogUtil.e(TAG, "uploadImages: 上傳成功");

}

@Override

public void onError(@NonNull Throwable e) {

}

@Override

public void onComplete() {

}

});
