调用外部Web服务的示例 [英] Example calling an external webservice

问题描述

我正在尝试通过在Visual Web中制作一些示例程序来学习ASP.NET

Developper 2005 Express Edition。


我正在尝试写一个客户端使用如下简单的Web服务：

http： //www.webservicex.net/uklocation.asmx?WSDL

我已将web服务添加到我的项目中，但如何继续？我已经找到了几个例子，但没有什么清楚我真正想要的东西。比如我在下面找到了

，但这与localhost有关。我在

本地主机上没有网络服务。我也不明白应该在哪里定义localhost。


protected void ConvertButton_Click（object sender，EventArgs e）

{

localhost.Convert wsConvert = new localhost.Convert（）;

double temperature =

System.Convert.ToDouble（TemperatureTextbox.Text）;

FahrenheitLabel.Text =Fahrenheit To Celsius = +

wsConvert.FahrenheitToCelsius（温度）.ToStrin g（）;

CelsiusLabel.Text =" Celsius To Fahrenheit =" +

wsConvert.CelsiusToFahrenheit（温度）.ToStrin g（）;

}


请给我一些提示！

I am trying to study ASP.NET by making some example programmes in Visual Web
Developper 2005 Express Edition.

I am trying to write a client that consumes a simple webservice like:

http://www.webservicex.net/uklocation.asmx?WSDL

I''ve added the webservice to my project, but how do I proceed? I have found
several examples but nothing clear what I really want. For example I have
found the below but that''s with localhost. I do not have the webservice on
local host. Nor do I understand where localhost should be defined anyway.

protected void ConvertButton_Click(object sender, EventArgs e)
{
localhost.Convert wsConvert = new localhost.Convert();
double temperature =
System.Convert.ToDouble(TemperatureTextbox.Text);
FahrenheitLabel.Text = "Fahrenheit To Celsius = " +
wsConvert.FahrenheitToCelsius(temperature).ToStrin g();
CelsiusLabel.Text = "Celsius To Fahrenheit = " +
wsConvert.CelsiusToFahrenheit(temperature).ToStrin g();
}

Please give me some hints!

推荐答案

试试这个演练：

您必须设置服务才能执行此操作。一旦你理解了这一点，你就可以创建其他服务或连接到你想要消费的服务。我可以

告诉你你所指出的服务，但它非常慢。

Try this walkthrough:

You will have to set up the service to do it. Once you understand that, you
can create other services or connect to the one you want to consume. I could
show you with the service you have pointed out, but it is extremely slow.

我认为您不是在寻找客户。这是一个我没有测试过b $ b b的例子，但它有一个基本的方法包装在一个类中。


服务= http://ws.cdyne.com/WeatherWS/Weather.asmx?wsdl


Class =


使用ServiceConsumptionLibrary.WeatherService;


命名空间ServiceConsumptionLibrary

{

公共类ServiceConsumer

{

public static WeatherService.ForecastReturn

GetForecastForUsPostalCode（string postalCode）

{

var client = new WeatherHttpGetClient（）;

var forecast = client.GetCityForecastByZIP（postalCode）;


返回预测;

}

}

}


我还没有通过这个测试然而（我会亲自创建一个单元测试），

但基本的想法是健全的，像.NET 2.0+一样适用于所有

服务。而且，是的，它比1.x更复杂。

I think you are not looking for the Client. Here is an example I have not
tested, but it has the basic methodology wrapped in a class.

Service = http://ws.cdyne.com/WeatherWS/Weather.asmx?wsdl

Class =

using ServiceConsumptionLibrary.WeatherService;

namespace ServiceConsumptionLibrary
{
public class ServiceConsumer
{
public static WeatherService.ForecastReturn
GetForecastForUsPostalCode(string postalCode)
{
var client = new WeatherHttpGetClient();
var forecast = client.GetCityForecastByZIP(postalCode);

return forecast;
}
}
}

I have not tested through this yet (I would create a unit test, personally),
but the basic idea is sound and works like .NET 2.0+ works with all
services. And, yes, it is a bit more complex than 1.x.

好​​的，现在为了傻事，我很抱歉这一定是一个真正的新问题，同时我也是寻求解决这个问题，但是：


使用ServiceConsumptionLibrary.WeatherService;

给予


错误1类型或命名空间名称''WeatherService''在命名空间''ServiceConsumptionLibrary'中不存在（你是否缺少程序集引用？）C：\ Document and Settings \Marc wentink \Mijn documenten \ Visual Studio 2005 \ WebSites\H8Async\App_Code\ServiceConsumer.cs 10 33 C：\ ... \ H8Async \


现在通常我会添加一个指向程序集的链接， dll，里面有WeatherService，但我现在该怎么办？我认为我没有带有WeatherService的dll。

"Cowboy (Gregory A. Beamer)" <No************@comcast.netNoSpamMschreef
Ok, now for something silly, and I am sorry this must be a real newbee question, and concurrently I am searching to solve this myself, but:

using ServiceConsumptionLibrary.WeatherService;
Gives

Error 1 The type or namespace name ''WeatherService'' does not exist in the namespace ''ServiceConsumptionLibrary'' (are you missing an assembly reference?) C:\Documents and Settings\Marc wentink\Mijn documenten\Visual Studio 2005\WebSites\H8Async\App_Code\ServiceConsumer.cs 10 33 C:\...\H8Async\

Now normally I would add a link to an assembly, a dll, with WeatherService in it, but what do I do now? I presume I do not have a dll with WeatherService in it.

这篇关于调用外部Web服务的示例的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
