Question

Android代码

HttpClient httpClient = new DefaultHttpClient();
                HttpPost httpPost = new HttpPost(
                        "http://192.168.1.104/Ceylon_Steel/service/getCategoriesAndItems");
                ResponseHandler<String> responseHandler = new BasicResponseHandler();
                String responseBody = httpClient.execute(httpPost, responseHandler);
                JSONObject posts = new JSONObject(responseBody);
                JSONArray jArray = posts.getJSONArray("categories");
                Log.i("Tag", jArray.toString());

Json

categories_and_items({
    categories: [
        {
            id: "c2",
            item: [
                {
                    itemId: "9",
                    itemCode: "FG039062",
                    description: "E1-LINER 38x26-R: NAKAYAMA NCF-2B IMPACT CHUSHER",
                    price: "0.00",
                    quantity: "100000"
                },

            ]
        },

    ]
})

在这里，我尝试使用上面的代码从json中检索数据并将其打印在日志上但是尝试我得到以下错误。

12-06 10:11:38.578: W/System.err(3695): org.json.JSONException: Value categories_and_items of type java.lang.String cannot be converted to JSONObject

Answer 1

我认为json无效。

是什么

categories_and_items( ... )

Answer 2

您的JSON回复无效。它应始终以{...}括号开头，而不是(..)括号。

如果可能，请删除(..)括号，如下所示更改您的回复：

categories_and_items{
    categories: [
        {
            id: "c2",
            item: [
                {
                    itemId: "9",
                    itemCode: "FG039062",
                    description: "E1-LINER 38x26-R: NAKAYAMA NCF-2B IMPACT CHUSHER",
                    price: "0.00",
                    quantity: "100000"
                },

            ]
        },

    ]
}

无法读取jsonp输出
