php服务器使用JSON解析简单字符串到Android客户端

php服务器使用JSON解析简单字符串到Android客户端,php,android,json,Php,Android,Json,大家好,我对Android客户端phpserver很陌生。我通过JSON遵循了一些post和response变量的教程,但是这个响应错误值转换为JSONObject JSONpost是成功的,但是响应是错误的 Android代码: HttpConnectionParams.setConnectionTimeout(httpParameters, 15000); HttpConnectionParams.setSoTimeout(httpParameters, 15000);

大家好,我对Android客户端
php
server很陌生。我通过
JSON
遵循了一些post和response变量的教程,但是这个响应错误<无法将java.lang.String类型的代码>值转换为JSONObject

JSON
post是成功的,但是响应是错误的

Android代码:

HttpConnectionParams.setConnectionTimeout(httpParameters, 15000);
HttpConnectionParams.setSoTimeout(httpParameters, 15000);           

HttpClient httpclient = new DefaultHttpClient(httpParameters);
HttpPost httppost = new HttpPost("http://192.168.1.1/databastest/login.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));        
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();

String result = EntityUtils.toString(entity);

// Create a JSON object from the request response
JSONObject jsonObject = new JSONObject(result);

//Retrieve the data from the JSON object
resultLoging = jsonObject.getString("ResultArray");


}catch (Exception e){
    Log.e("ClientServerDemo", "Error:", e);
    exception = e;
}

return true;
}

@Override
protected void onPostExecute(Boolean valid){
    //Update the UI
    Toast.makeText(mContext, resultLoging, Toast.LENGTH_LONG).show();
    if(exception != null){
        Log.i("Error",exception.getMessage());
        Toast.makeText(mContext, exception.getMessage(), Toast.LENGTH_LONG).show();
        }
    }
php代码

mysqli_query($con,"INSERT INTO usersacc
(phone, password) VALUES('$pho', '$pass')");


        #Build the result array (Assign keys to the values) 
        $result_data = array( 
           'ResultArray' => 'success',
            ); 

        #Output the JSON data 
        echo json_encode($result_data);  

插入成功,但结果未完成。

用此代码替换您的代码可能会起作用。以对象而不是字符串的形式从服务器获取响应

Object result = EntityUtils.toString(entity);
JSONObject jsonObject = new JSONObject(result.toString()); 
resultLoging = jsonObject.getString("ResultArray");
尝试打印“jsonObject”数据,找出数据格式。尝试打印“jsonObject”数据,是json格式的吗?Log.i(“jsonformabc”,jsonObject.toString());我使用了这个,但没有响应??使用Log.i(“result”,result.toString());并检查响应。仍然为空。问题出在您的服务器上,服务器未返回数据,请在浏览器中尝试服务器脚本,并检查数据是否正在打印。
