Question

我正在使用OKHTTP并使用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);

作为From代码，（al is ArrayList）你可以看到我必须发送带有单个Packname的多个项目，这就是我使用for循环的原因。

但实际上，由于requestBody在for循环内部覆盖，实际上只有最后一项保存在服务器上。

如何通过将所有项目添加到请求者来发送所有项目？

试试这可能会对你有帮助。

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);

使用multipart with for循环
