WebService使用UTF-16编码而非UTF-8

Question

WebService使用UTF-16编码而非UTF-8

3

在C# .NET中，是否可以强制WebService使用UTF-16编码，而不是UTF-8编码？

我创建了一个简单的WebService，用于接收XML文档。

WebService.asmx

public class WebApplication1 : WebService
{
    [WebMethod(Description = "Test")]
    public string Test(XmlDocument xmlDocument)
    {
        return "Test";
    }
}

输出

POST /WebService.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/Test"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <Test xmlns="http://tempuri.org/">
      <xmlDocument>xml</xmlDocument>
    </Test>
  </soap:Body>
</soap:Envelope>

若我试图传递一个 UTF-16 编码的 XML 文档，会出现以下错误：

XML Content:
<?xml version="1.0" encoding="utf-16"?> <Affiliate xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" leadinnumber="ABCDABCD" xmlns:xsd="http://www.w3.org/2001/XMLSchema" mediaid="30000">

    <FirstName>Delivery</FirstName>
    <Surname>Testing</Surname>
    <Tel>02034056978</Tel>
    <Email>adfsdfsdfsd@live.co.uk</Email>
  </Details>
</Affiliate>

对于XML UTF-16，您的响应仅为UTF-8。 - Krsna Kishore

我意识到SOAP是UTF-8编码的，我该如何强制WebService使用UTF-16？ - iggyweb

您需要配置您的网络服务。前往Web.config的全球化部分，将UTF-8更改为UTF-16。应将globalization标签的requestEncoding和responseEncoding属性设置为UTF-16。

<globalization requestEncoding="utf-8" responseEncoding="utf-8"/>

必须被转换为

<globalization requestEncoding="utf-16" responseEncoding="utf-16"/>

这个更改将允许网络服务接受UTF-16格式的请求和发送响应。编辑如果要通过代码手动设置编码，您可以使用以下代码：

        // Set the path of the config file.
        string configPath = "";            
        Configuration config = WebConfigurationManager.OpenWebConfiguration(configPath);
        GlobalizationSection configSection = (GlobalizationSection)config.GetSection("system.web/globalization");            
        configSection.RequestEncoding = Encoding.Unicode;
        configSection.ResponseEncoding = Encoding.Unicode;
