Question

我正在尝试将HashMap发送到Android的Magento REST API。其余的包含一个数组元素，如下所示。

[{
    "id": "26",
    "label": "",
    "position": "1",
    "exclude": "0",
    "url": "http:\/\/localhost\/magento\/media\/catalog\/product\/6\/1\/61UROlGlryL._UL1500_.jpg_20.jpg",
    "types": []
}]

我尝试使用HttpPost发送数据如下所示。

Map < String, String > productimages = new HashMap < String, String > ();

productimages.put("file_mime_type", mime);
productimages.put("file_content", encodedImage);
productimages.put("file_name", pictureName);

String[] datas = {
  "image", "small_image", "thumbnail"
};
productimages.put("types", datas.toString());
Gson gson = new Gson();
String productimages_json = gson.toJson(productimages);
StringEntity productimages_entity = new StringEntity(productimages_json, HTTP.UTF_8);
HttpPost httppost_img = new HttpPost(URL_PRODUCTS + "/6/images");
httppost_img.setHeader("Content-Type", "application/json");
httppost_img.setHeader("Accept", "application/json");
httppost_img.setEntity(productimages_entity);
Log.d("inserted", "");
HttpResponse response_img = client.execute(targetHost, httppost_img, localContext);

所有数据而不是“类型”：[]正在点击Web服务。当像productimages.put("types", "image");这样的单个字符串发送数据时，它成功点击了Web服务但我需要发送多个值。我也尝试了以下但没有结果。

Map<String,String[]> productimages = new HashMap<String, String[]>();
String[] datas = {"image","small_image","thumbnail"};
productimages.put("types", datas);

如何使用单个键将String []值发送到REST Web Service。任何人都可以帮我解决这个问题。

Answer 1

尝试

for (int i = 0; i < datas.length; i++) {
    productimages.put("types[" + Integer.toString(i) + "]", datas[i]);
}

Answer 2

正如先生：Jon Skeet建议我，我能够将数据作为对象发送如下。

Map<String,Object> productimages = new HashMap<String, Object>();
            List<String> datas = new ArrayList<String>();
            datas.add("image");
            datas.add("small_image");
            datas.add("thumbnail");

productimages.put("file_mime_type", mime);
productimages.put("file_content", encodedImage);
productimages.put("file_name", pictureName);

productimages.put("types", datas);
