Retrofit2上载带有Multipart或RequestBody的图像失败

Question

但没有一个真正成功。

第一种方式通过@multipart：

interface Api {   
@Multipart
@POST("/upload-file")
fun uploadFile(@Part("file") file: RequestBody,
               @Part("data") id: FileUploadModel): Single<Response<AdvertisementResponse>>
}

和方法：

 override fun uploadFile(
    id: FileUploadModel,
    filePath: String
): Single<Response<AdvertisementResponse>> {

    val requestFile = RequestBody.create(MediaType.parse("image/*"), file)

    return api.uploadFile(requestFile, id)
}

 @POST("/upload-file")
 fun uploadFile(@Body requestBody: RequestBody): Single<Response<AdvertisementResponse>>

override fun uploadFile(
    id: FileUploadModel,
    filePath: String
): Single<Response<AdvertisementResponse>> {

    val file = File(filePath)
    val builder = MultipartBody.Builder()
    builder.setType(MultipartBody.FORM)

    val requestFile = RequestBody.create(MediaType.parse("image/*"), file)

    builder.addFormDataPart("file", file.name, requestFile)
    builder.addFormDataPart("data", id.toJson())

    return api.uploadFile(builder.build())
}

@Multipart
@POST("/upload-file")
fun uploadFile(@Part("file") file: MultipartBody.Part,
               @Part("data") id: FileUploadModel): Single<Response<AdvertisementResponse>>

 override fun uploadFile(
    id: FileUploadModel,
    filePath: String
): Single<Response<AdvertisementResponse>> {

    val file = File(filePath)
    val requestFile = RequestBody.create(MediaType.parse("image/*"), file)
    val multipartFile = MultipartBody.Part.createFormData("file", file.name, requestFile)

    return api.uploadFile(multipartFile, id)
}

我想知道为什么改型不能完成这样的请求。

谢谢你的任何建议

干杯

Answer 1

该问题是由于无法从磁盘读取文件造成的。

在Android sdk 29中，将Android:requestlegacyexternalstorage=“true”添加到Android清单中对我来说很有效。

<application
android:name=".MyApplication"
android:requestLegacyExternalStorage="true" ...

除了添加 ion之外，android:name=“android.permission.read_external_storage” />权限。
