在多部分表单数据未到达服务器的情况下改造POST请求

Question

val builder = MultipartBody.Builder()
builder.setType(MultipartBody.FORM)
var jsonArray = JSONArray()
for ((index, value) in lineItems.withIndex()) {
    var jsonObject = JSONObject()

    jsonObject.accumulate("Room_id", lineItems[index].roomId)
    jsonObject.accumulate("jobTitle", lineItems[index].jobTitle)
    jsonObject.accumulate("floorLevel", lineItems[index].floorLevel)
    jsonObject.accumulate("jobTrade", lineItems[index].jobArea)
    jsonObject.accumulate("jobWork", lineItems[index].jobWork)
    jsonObject.accumulate("desc", lineItems[index].desc)
    jsonObject.accumulate("isFixed", lineItems[index].isFixed)
    jsonObject.accumulate("hourlyCost", lineItems[index].cost)
    jsonObject.accumulate("hourlyTotal", lineItems[index].total)
    jsonObject.accumulate("hourlyDuration", lineItems[index].duration)
    jsonObject.accumulate("fixedCost", lineItems[index].fixedCost)
    if (lineItems[index].lineItemId!="") {
        jsonObject.accumulate("_id", lineItems[index].lineItemId)
    }
    jsonArray.put(jsonObject)
    Log.d("json array",jsonArray.toString())

}

builder.addFormDataPart("lineHeight", jsonArray.toString())
for ((i, value) in lineItems.withIndex()) {
    var imageList = ArrayList<String>()

    if (lineItems[i].imageList!=null && lineItems[i].imageList!!.size>0) {
        imageList = lineItems[i].imageList!!

        for ((j, path) in imageList.withIndex()) {
            if (!imageList[j].contains("http")) {
                val file = File(path)
                val requestFile = 
                    RequestBody.create(MediaType.parse("image/"+
                    file.name.substring(file.name.indexOf(".")+1)), file)
                val body = MultipartBody.Part.createFormData("photos" + i,
                    file.name, requestFile)
                builder.addPart(body)
            }
        }
    }
 }

val requestBody = builder.build()

以下是呼叫代码：

fun addLineItems(@Header("Authorization") token: String,
                 @Path("jobId") jobId: String,
                 @Body body: okhttp3.RequestBody): Call<Response>

我向一个web服务人员确认，当我从应用程序调用这个API时，他们在日志中没有得到任何东西，而当从Postman调用same时，日志会显示出来。

我就是这么试的

这就是我如何准备多部分实体。

File file = new File(currentFilePath);
if (file.exists()) {
String name = URLConnection.guessContentTypeFromName(file.getName());
RequestBody requestFile = RequestBody.create(MediaType.parse(name), file);
MultipartBody.Part multipart = MultipartBody.Part.createFormData("file", file.getName(), requestFile);
}

这是上传文件的方法

@Multipart
@POST("your url")
fun uploadFile(@Header("Authorization") token: String, @Path("jobId") jobId: String,
                @Part file: MultipartBody.Part): Call<Response>
