Android 使用多部分for循环

我使用OKHTTP和Multipart将图像发送到服务器。 我的代码如下：

RequestBody requestBody = null;
for (int i = 0; i < noOfItems; i++) {
                requestBody = new MultipartBuilder().type(MultipartBuilder.FORM)
                        .addFormDataPart("func", "savepacket")
                        .addFormDataPart("userid", String.valueOf(mLoginPref.getInt("userId", 1)))
                        .addFormDataPart("packname", strPackname)
                        .addFormDataPart("image", str + ".png", RequestBody.create(MediaType.parse("image/png"), imagePath))
                        .addFormDataPart("count", String.valueOf(noOfItems))
                        .addFormDataPart("item_name" + String.valueOf(i + 1), al.get(i).getStrItemName())
                        .addFormDataPart("tag_item" + String.valueOf(i + 1), al.get(i).getStrItemTag())
                        .addFormDataPart("note" + String.valueOf(i + 1), al.get(i).getStrComment())
                        .addFormDataPart("image" + String.valueOf(i + 1), al.get(i).getStrItemName() + ".png", RequestBody.create(MediaType.parse("image/png"), al.get(i).getStrItemImage()))
                        .build();
            }
            mstrQRResponse = HttpUtils.postRun("pack", requestBody);

RequestBody RequestBody=null；
for（int i=0；i

从代码中，（al是ArrayList）您可以看到，我必须使用单个Packname发送多个项目，这就是我使用for循环的原因

但，实际上只有最后一项保存在服务器上，因为requestBody在for循环中获得覆盖

如何通过将所有项目添加到requestbody来发送

试试这个，也许会对你有帮助

MultipartBuilder multipartBuilder = new MultipartBuilder().type(MultipartBuilder.FORM);
    RequestBody requestBody = null;
    for (int i = 0; i < noOfItems; i++) {
        multipartBuilder
                .addFormDataPart("func", "savepacket")
                .addFormDataPart("userid", String.valueOf(mLoginPref.getInt("userId", 1)))
                .addFormDataPart("packname", strPackname)
                .addFormDataPart("image", str + ".png", RequestBody.create(MediaType.parse("image/png"), imagePath))
                .addFormDataPart("count", String.valueOf(noOfItems))
                .addFormDataPart("item_name" + String.valueOf(i + 1), al.get(i).getStrItemName())
                .addFormDataPart("tag_item" + String.valueOf(i + 1), al.get(i).getStrItemTag())
                .addFormDataPart("note" + String.valueOf(i + 1), al.get(i).getStrComment())
                .addFormDataPart("image" + String.valueOf(i + 1), al.get(i).getStrItemName() + ".png", RequestBody.create(MediaType.parse("image/png"), al.get(i).getStrItemImage()));
    }
    requestBody = multipartBuilder.build();
    mstrQRResponse = HttpUtils.postRun("pack", requestBody);

MultipartBuilder MultipartBuilder=new MultipartBuilder（）.type（MultipartBuilder.FORM）；
RequestBody RequestBody=null；
for（int i=0；i

在for循环内部，每次创建

requestBody的对象时，然后调用
postRun（）
。这就是为什么最后一个项目正在上载到服务器。是的，这是ri8。。但是我怎么解决呢？谢谢兄弟。。已在服务器上成功添加所有项目。
