c# - WebService SOAP 编码 UTF-16 而不是 UTF-8

Question

是否可以强制 C# .NET 中的 WebService 使用编码 UTF-16 而不是 UTF-8？

我创建了一个接收 XML 文档的简单 WebService。

网络服务.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>

如果我尝试传递 UTF-16 编码的 XML 文档，我会收到以下错误:

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">

    <Tel>02034056978</Tel>
    <Email>adfsdfsdfsd@live.co.uk</Email>
  </Details>
</Affiliate>

您必须配置您的网络服务。转到 Web.config 的全局化部分并制作 UTF-16 而不是 UTF-8。全局化标签的 requestEncoding 和 responseEncoding 属性应设置为 UTF-16。

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

必须转换为

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

此更改将允许 Web 服务以 UTF-16 格式接受请求和发送响应。

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;
