Question

我目前正在开发和Android应用程序，它从ASP.NET WebApi服务收集数据。该服务有效，但我无法在android中获取JSON对象，我必须转换为JSON数组或JSON对象，我已经尝试了很多答案，但没有成功。这是我的服务器端代码片段：

 // GET api/uconnectservice
        public String Get()
        {

            var json = JsonConvert.SerializeObject(

                sampledata.GetAllDummy()
            );
            return json;

            //return sampledata.GetAll();
        }

给出：

    <string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">
    [{"AccountType":"15516321","CustomerName":"1MACMONSAM NICOLAS","Currentbalance":"1100,000.00","AllTransactions":[{"ID":103,"DescriptionoOfTransaction":"I need money right now","Debit":"5001","Credit":"0","TransactionDate":"15/12/2016 22:35:03","ValueDate":"15/12/2016 22:35:03"},{"ID":105,"DescriptionoOfTransaction":"I need money right now","Debit":"5002","Credit":"0","TransactionDate":"16/12/2016 22:35:03","ValueDate":"16/12/2016 22:35:03"},{"ID":107,"DescriptionoOfTransaction":"I need money right now","Debit":"5003","Credit":"0","TransactionDate":"17/12/2016 22:35:03","ValueDate":"17/12/2016 22:35:03"}......MORE JSON.........{"ID":113,"DescriptionoOfTransaction":"I need money right now","Debit":"5006","Credit":"0","TransactionDate":"20/12/2016 22:35:03","ValueDate":"20/12/2016 22:35:03"},{"ID":115,"DescriptionoOfTransaction":"I need money right now","Debit":"5007","Credit":"0","TransactionDate":"21/12/2016 22:35:03","ValueDate":"21/12/2016 22:35:03"},{"ID":117,"DescriptionoOfTransaction":"I need money right now","Debit":"5008","Credit":"0","TransactionDate":"22/12/2016 22:35:03","ValueDate":"22/12/2016 22:35:03"},{"ID":119,"DescriptionoOfTransaction":"I need money right now","Debit":"5009","Credit":"0","TransactionDate":"23/12/2016 22:35:03","ValueDate":"23/12/2016 22:35:03"},{"ID":121,"DescriptionoOfTransaction":"I need money right now","Debit":"50010","Credit":"0","TransactionDate":"24/12/2016 22:35:03","ValueDate":"24/12/2016 22:35:03"}]}]
</string>

等，这很好

在Android端，我必须使用此服务，这是我的代码：

String URL = "http://192.168.1.101/UnicsApplication/api/uconnectservice";

    JSONObject jsonObject;
    private final OkHttpClient client = new OkHttpClient();

    public void run() throws Exception {
        Request request = new Request.Builder().url(URL).build();

        client.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                e.printStackTrace();

            }
try (ResponseBody responseBody = response.body()) {

                    if (!response.isSuccessful())

                        throw new IOException("Unexpected code " + response);

                    Headers responseHeaders = response.headers();

                    for (int i = 0, size = responseHeaders.size(); i < size; i++) {

                        Log.d("Results", responseHeaders.name(i) + ": " + responseHeaders.value(i));

                    }
                    //Log.d("Results", responseBody.string());

                    try {
                        //get JSON objetc first 

                        jsonObject = new JSONObject(responseBody.string());

                        Log.d("JsonObject", jsonObject.toString());

                    } catch (JSONException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }

调用e.printstackTrance方法。我从Logcat获取的错误消息如下：

这是一个JSON字符串吗？我该怎么做才能获得稍后将转换为集合的JSON对象？。任何指导或帮助都将非常感激。日Thnx。

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">

是无效的JSON，看起来你先得到一些包含json的xml。我的建议是在服务器端正确删除它。如果不可能，则在开始解析之前从响应中删除字符串标记

无法将Android中的JSON从WebApi转换为Json对象
