当我这样给予我的URL时：https://exampl/api/ {{数据源1.表5002#csv.objectId}}/模式/{{数据源1.表5002#csv.model}}，现在它工作正常。

下面是一个更复杂的插件来做到这一点：

    public class PluginWtConfigReader : WebTestPlugin
    {      
        static string _webServer = "webServer not set";
        static string executingDir = Environment.CurrentDirectory; // usually puts us in the TestResults directory
        static string solutionRoot = Directory.GetParent(executingDir).Parent.Parent.Parent.Parent.FullName; // back out to root

        {
            string pathToTargetConfigFile = "";
            try
            {
                string[] fileArray = Directory.GetFiles(solutionRoot, configFileName, SearchOption.AllDirectories);
                pathToTargetConfigFile = fileArray[0];
            }
            catch (Exception ex)
            {
                Debug.WriteLine($"Web Test Plugin: Could not find config file. Did you populate the plugin property?");
            }

            ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap()
            {
                ExeConfigFilename = pathToTargetConfigFile
            };

            Configuration config = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
                        
            _webServer = config.AppSettings.Settings["webServer"].Value.ToString();

            string fullOldUrl = e.Request.Url;
            Uri newUri = new Uri(fullOldUrl);
            string oldHost = newUri.DnsSafeHost; // gets just a segment of the URI, just the host.
            e.Request.Url = e.Request.Url.Replace(oldHost, _webServer);

}

此插件允许您在app.config文件中指定URL。将其添加到webtest中，它只会更改URL的主机名部分。您可以编写更多代码来获取要替换的URL的不同段。
