通过Retrofit上传文件到服务器失败

Question

我正在尝试通过改造将文件上传到服务器。在邮递员中我成功收到了 api 响应。

但是当我在项目中调用 api 时，api 调用失败。

改装方法：

@Multipart
@POST("/upload/")
fun fileUpload(@Part file:MultipartBody.Part): Call<FileUploadResponse>

响应数据类：

data class FileUploadResponse(
val created_at: String,
val file: String,
val id: Int,
val is_active: Boolean,
val updated_at: String,
val uuid: String  )

我的电话是：

 override fun fileUpload(context: Context,path: String): MutableLiveData<FileUploadResponse> {

    val apiServices = rInstance.getRetrofitInstance()?.create(ApiServices::class.java) 
    
    val file = File(path)
    val requestFile = file.asRequestBody("multipart/form-data".toMediaTypeOrNull())
    val filePart = MultipartBody.Part.createFormData("file", file.name, requestFile)
    Log.d("EWNMAP","path: $path, requestfile: $requestFile , filepart: $filePart")

    val call =apiServices?.fileUpload(filePart)
    call?.enqueue(object :Callback<FileUploadResponse>{
        override fun onResponse(
            call: Call<FileUploadResponse>,
            response: Response<FileUploadResponse>
        ) {
        if (response.isSuccessful){
            fileUploaded.postValue(response.body())
            Log.d("EWNMAP","Uploaded file: ${response.body()?.file}")
        }else Toast.makeText(context,"File Upload not successful",Toast.LENGTH_LONG).show()
        }

        override fun onFailure(call: Call<FileUploadResponse>, t: Throwable) {
            Toast.makeText(context,"File Upload failed",Toast.LENGTH_LONG).show()
        }

    })

    return fileUploaded
}

我使用了 okhttp 记录器，所以在 logcat 中我得到了这些：

这里有什么问题？

那是存储权限问题
