我试图在我的表面上运行一个 React 项目作为开发服务器，如果给我下面和标题中显示的错误。当我在我的电脑上运行相同的配置时，我没有遇到这个问题。（我尝试创建相同的条件，但它不起作用）。

错误：

我正在尝试在一个项目中安装 node-sass，该项目在我的电脑上完美构建和运行，但在我的表面上，我在尝试安装软件包时遇到了重大问题。

注意：我已经多次尝试重新安装和重建项目。

我是 Swagger.io 的新手，也是 Spring Fox 的新手。我遇到的问题是，由于某种原因，一个对象没有正确引用其模型。

用户界面中的错误：

错误是因为 JSON 中的结果如下：

"schema": {
"$ref": "#/definitions/Error-ModelName{namespace='online.staffmanager.backend.auth.model.dto', name='UserChangeSet'}"
}

如果我将其更改为：

"schema": {
"$ref": "#/definitions/UserChangeSet"
}

它确实有效。我不知道为什么注释会这样映射。

我的注释：

 @Operation(
            tags = "auth",
            summary = "Create a new User Account",
            responses = {
                    @ApiResponse(
                            responseCode = "200",
                            content = @Content(schema = @Schema(implementation = TokenInfo.class))),
                    @ApiResponse(
                            responseCode = "201",
                            content = @Content(schema = @Schema(implementation = UserChangeSet.class)))
            }
    )

SpringFox配置：

@Configuration
@EnableSwagger2
@EnableWebMvc
public class SpringFoxConfig {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)

我想切断我的字符串"ftp://user:password@ftp.domain.com:21"以将每篇文章放在一个字符串中

换句话说，我想要：

String ftp = "ftp.domain.com"

String user = "user"

String password = "password"

String port = "21"

这段代码有效，但有点脏，对吧？

String fullFtpAdress = "ftp://user:password@ftp.domain.com:21";
fullFtpAdress = fullFtpAdress.substring(6);
String[] parts1 = fullFtpAdress.split(":",2);
String user = parts1[0];
String[] parts2 = parts1[1].split("@");
String password = parts2[0];
String[] parts3 = parts2[1].split(":");
String ftp = parts3[0];
String port = parts3[1];

你有其他解决方案吗？

谢谢 ：）

由于错误，我需要在我的头文件和 Cpp 中实现一个头文件保护，因为在我不知道出了什么问题之前我从未使用过它，因为在某些类上它可以工作，而在一个类上它不会......最初问题更大，但我想我把它缩小到问题的根源。
