如何从改造中发送未编码的base64？

Question

您好，我想通过改装将未编码的base64图像发送到Web。 我所编码的意思是将“ /”更改为％2F。但是我想发送未编码的正文。

同一图像的已编码和未编码的base64

例如（已编码）-

这些指向同一张图片，但我想发送第二张作为正文。我也尝试过在编码中加编码为true，但没有运气。

@FormUrlEncoded
    @POST("{id}/profile/uploadPicture")
    public fun uploadImage(
            @Path(value = "id", encoded = true) userId: Int,
            @Field(value = "picture" , encoded = true) picture:String)
            : Call<ImageUploadResponse>
}
