kotlin代码可能会对您有所帮助。

val requestFile: RequestBody =
RequestBody.create("multipart/form-data".toMediaTypeOrNull(), file)
val requestBody: RequestBody = MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("name", "param1")
.addFormDataPart("fathername", "param2")
.addFormDataPart("cnic", "88")
.addFormDataPart("rollno", "2")
.addFormDataPart("image", "image",requestFile)
.build()

在界面中制作类似的抽象函数

@POST("v1/addstudentinfo")
fun sendStudentData(@Body req:RequestBody): Call<StudentInfoResponse>
