Android 如何从 web 服务将数据插入 sql - 需要获取错误有效的 soap 操作

Question

我已经尝试按照每个谷歌搜索如何执行此操作，但我收到错误

android Unable to handle request without a valid action parameter. Please supply a valid soap action

我的 web 服务是 .net 4.0 我有一个 asmx 端口 9022，这是我的 asmx

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Data.SqlClient;


namespace MyFirstWebService
{
    /// <summary>
    /// Summary description for Math
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    // [System.Web.Script.Services.ScriptService]
    public class Math : System.Web.Services.WebService
    {

        [WebMethod]
        public string HelloWorld()
        {
            return "Hello World";
        }

        [WebMethod]
        public int Add(int a, int b)
        {
            return (a + b);
        }

        [WebMethod]
        public System.Single Subtract(System.Single A, System.Single B)
        {
            return (A - B);
        }

        [WebMethod]
        public System.Single Multiply(System.Single A, System.Single B)
        {
            return A * B;
        }

        [WebMethod]
        public System.Single Divide(System.Single A, System.Single B)
        {
            if (B == 0)
                return -1;
            return Convert.ToSingle(A / B);
        }

        [WebMethod]
        public void InsertComment(string value)
        {
            SqlParameter sqlParameter = new SqlParameter();
            sqlParameter.ParameterName = "NewComment";
            sqlParameter.Value = value;
            List<SqlParameter> sqlParam = new List<SqlParameter>();
            sqlParam.Add(sqlParameter);
            SQLOperations.executeStoredProcedure("InsertNewComment", sqlParam);

        }
    }
}

这是我的方法

namespace MyFirstWebService
{
    public class SQLOperations

            return isSafe;

        }

        private static SqlConnection webServiceConnection()
        {
            SqlConnection sqlCon = new SqlConnection(ConfigurationManager.ConnectionStrings["SQL"].ConnectionString);
            sqlCon.Open();
            return sqlCon;

        }

        private static SqlCommand sqlCmd(string cmdName, SqlConnection sqlCon, List<SqlParameter> sqlParameters)
        {



            // 1.  create a command object identifying the stored procedure
            SqlCommand _sqlCmd = new SqlCommand(cmdName, sqlCon);

            // 2. set the command object so it knows to execute a stored procedure
            _sqlCmd.CommandType = CommandType.StoredProcedure;

            // 3. add parameter to command, which will be passed to the stored procedure
            if (sqlParameters != null)
                for (int i = 0; i < sqlParameters.Count; i++)
                {
                    _sqlCmd.Parameters.Add(sqlParameters[i]);
                }

            return _sqlCmd;

        }

        public static void executeStoredProcedure(string cmdName,List<SqlParameter> sqlParameters)
        {

            using (SqlConnection conn = webServiceConnection())
            {


                SqlCommand cmd = sqlCmd(cmdName, conn, sqlParameters);


                cmd.ExecuteNonQuery();


            }

        }

    }
}

Answer 1

调试与解决方案:

解决方案 1:

你说我有一个在端口 9022 上的 asmx 但在你的代码中你使用的是 9020

private String NAMESPACE = "http://example.net:9020/";
private String SOAP_ACTION = "http://example.net:9020/InsertComment";
private String URL="http://example.net:9020/Math.asmx?";

解决方案 2:

2.1 将您的代码编辑为:

删除“？”来自您的 URL 变量

private String URL="http://example.net:9020/Math.asmx?";

2.2 将您的代码编辑为:

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

代替 SoapEnvelope.VER12

2.3 将您的代码编辑为:

SoapObject resultRequestSOAP = null; 和 resultRequestSOAP = (SoapObject) envelope.getResponse();

代替 Object resultRequestSOAP = null; 和 resultRequestSOAP = (Object) envelope.getResponse();

2.4 将您的代码编辑为:

HttpTransportSE androidHttpTransport = new HttpTransportSE(URL,60000);

代替 HttpTransportSE androidHttpTransport = getHttpTransportSE();

解决方案 3:

我编辑并尝试了您代码的修改版本:

private String URL="http://example.net:9020/Math.asmx";

//...

//Object  resultRequestSOAP = null;
public void onClick(View v) {
    new Thread() {
        @Override
        public void run() {//Create request

            //Variables 
            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
            //Use this to add parameters - reactivate this line bellow to match your needs after testing this at first 
            //request.addProperty("NewComment", "cell");
            //Could also try the following instead of the line bellow //SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12); //envelope.dotNet = true; //envelope.setOutputSoapObject(request);
            SoapSerializationEnvelope envelope = getSoapSerializationEnvelope(request);
            HttpTransportSE androidHttpTransport = new HttpTransportSE(URL,60000);

            //if does not work you may decommand the line bellow
            //androidHttpTransport.debug = true;

            try {

                androidHttpTransport.call(SOAP_ACTION, envelope);
                SoapObject resultRequestSOAP = (SoapObject)envelope.bodyIn;

            } catch (Exception e) {
                Log.w("myApp", e.getMessage());
                Log.w("myApp", e.getCause());

            }

        }
    }.start();
}

代替

private String URL="http://example.net:9020/Math.asmx?";

//...

    Object  resultRequestSOAP = null; //this line should not be here
    public void onClick(View v) {
          //...
    }

解决方案 4:

检查/重置您的网络服务 asmx 和端口 9022。
