问题描述

我在asp.net中使用货币转换器，我正在尝试转换价值，但它显示错误plz建议。



我有什么试过：



当我点击转换按钮时显示远程服务器返回并出错（404）。

 [WebService（Namespace =   http：// tempuri.org /）] 
 [WebServiceBinding（ConformsTo = WsiProfiles.BasicProfile1_1）] 
 [System.ComponentModel.ToolboxItem（ false ）] 
 [ScriptService] 
  public   class  WebService：System.Web。 Services.WebService 
 {
 [WebMethod] 
  public   decimal  ConvertGOOG （十进制金额， string  fromCurrency，  string  toCurrency）
 {
 WebClient web =  new  WebClient（）; 
  //   string url = string.Format（http://www.google.com/ig/计算器？hl = en& q = {2} {0}％3D％3F {1}，fromCurrency.ToUpper（），toCurrency.ToUpper（），amount）;  
 Uri uri = < span class =code-keyword> new  Uri（ string  .Format（ < span class =code-string> http://www.google.com/ig/calculator?hl=zh-CN&q= {2} {0}％3D％3F {1}，fromCurrency。 ToUpper（），toCurrency.ToUpper（），amount））; 
  string  url = uri.AbsoluteUri + uri.Fragment; 
  string  response = web.DownloadString（url）; 
正则表达式regex = 新正则表达式（  rhs ：\\\（\\d *。\\\\ *） ）; 
匹配匹配= regex.Match（响应）; 
 //十进制速率= System.Convert.ToDecimal（regex.Match（response）.Groups [1] .Value）; 
 decimal rate = System.Convert.ToDecimal（match.Groups [1] .Value）; 
 return rate; 
} 
}  

解决方案

你请求的网址不存在，它可能在某一点上完成但不再存在。它们似乎已将它们的api移动到其他地方

引用：

远程服务器返回错误（404）。

唯一的可能是你向远程服务器发送了错误的请求。 br />
建议：打印您的请求，看看它是否符合您的期望。

然后在浏览器中复制/粘贴，看看是否收到错误。



其他可能性，远程服务器可以防止滥用。



看起来像 http://www.google.com/ig/calculator [ ^ ]不存在。

解决方案

The url you are requesting doesn't exist, it maybe did at one point but not any more. They seem to have moved their api to somewhere else

Quote:

the remote server returned and error(404).

The only possibility is that you send a wrong request to remote server.
Advice: print your request and see if it match your expectations.
Then copy/paste in your browser to see if you get the error.

Other possibility, the remote server can have protection against abuse.

Looks like "http://www.google.com/ig/calculator[^] doesn't exist.
