Question

我的问题是，当我尝试从我的wcf服务解析到android时，它给了我一个错误。我的服务的回报是使用JSON。这是我的android代码：

  DefaultHttpClient client = new DefaultHttpClient();
    // http get request
    HttpGet request = new HttpGet("http://XXX.XXX.XXX.XXX:8181/Managers/Authentification.svc/authen/?loga="+t1.getText().toString()+"&pass="+t2.getText().toString());

    // set the hedear to get the data in JSON formate
    request.setHeader("Accept", "application/json");
    request.setHeader("Content-type", "application/json");

    //get the response
    HttpResponse response = client.execute(request);
    System.out.println("Connectee--->" +response.getAllHeaders());

    HttpEntity entity = response.getEntity();

    //if entity contect lenght 0, means no data exist in the system with these code
    if(entity.getContentLength() != 0) {
        // stream reader object
        Reader employeeReader = new InputStreamReader(response.getEntity().getContent());
        //create a buffer to fill it from reader
        char[] buffer = new char[(int) response.getEntity().getContentLength()];
        //fill the buffer by the help of reader
        employeeReader.read(buffer);
        //close the reader streams
        employeeReader.close();

        //for the employee json object
        JSONObject tt =  new JSONObject(new String(buffer));

        System.out.println("..................OK.........................");

        System.out.println("Reference: " + tt.getString("Reference"));



    }
    else {
        System.out.println("...................Not OK........................");
    }

}
catch (JSONException e) {
    System.out.println("...................ERRORJSON........................");
    e.printStackTrace();
} catch (Exception e) {
    // TODO Auto-generated catch block
    System.out.println("...................ERROR........................");
    e.printStackTrace();
}

}
});

错误消息：

05-06 16:34:04.296: I/System.out(7257): ...................ERRORJSON........................

Answer 1

你有一个数组属性：Reference，必须在JSONString中定义，如下所示： {＆＃34;参考＆＃34;：[]} 例如 {＆＃34;参考＆＃34;：[{＆＃34; ID＆＃34;：1，＆＃34;引用名称＆＃34;：＆＃34; NAME1＆＃34;}，{＆＃34; ID＆＃34 ;：2＆＃34;引用名称＆＃34;：＆＃34; NAME2＆＃34;}]}

Java.lang.String无法转换为jsonobject
