android - Retrofit 设置上传图片类型为image/png 后台接收类型却为Application/json?

Question

File imageFile = new File(imagePath);

    ToolUtils.Log("imageFile = "+imageFile.getPath());
    String imageName = splitPath(imagePath);
    RequestBody requestBody = RequestBody.create(MediaType.parse("multipart/form-data"),imageFile);
    //RequestBody requestBody = RequestBody.create(MediaType.parse("image/jpg"),imageFile);
    
    两种方式构建RequestBody对象php后台得到的type都为applicattion/json
    是否是因为.addConverterFactory(GsonConverterFactory.create())的原因？

查看下你的Retrofit的版本，2.X的版本中上傳圖片的方式發生了變化，使用MultipartBody.Part如下

RequestBody requestFile =RequestBody.create(MediaType.parse("multipart/form-data"), file);
// MultipartBody.Part is used to send also the actual file name
MultipartBody.Part body =MultipartBody.Part.createFormData("image", file.getName(), requestFile);
