在Linux环境下,处理Swagger跨域问题的方法与在其他操作系统下的方法相同。这里提供两种解决方案:一种是通过配置Swagger自身来解决跨域问题,另一种是通过修改Nginx或Apache等Web服务器的配置来实现跨域。
方案一:配置Swagger自身解决跨域问题
打开Swagger配置文件。通常情况下,这个文件名为swagger-config.yaml或swagger-config.json。如果你使用的是Springfox库,那么配置文件可能是SwaggerConfig.java。
在配置文件中添加以下内容:
对于swagger-config.yaml或swagger-config.json文件:
swagger:
cors:
allowed-origins: ["*"]
allowed-methods: ["GET", "POST", "PUT", "DELETE", "OPTIONS"]
allowed-headers: ["Content-Type", "Authorization", "X-Requested-With"]
allow-credentials: true
对于SwaggerConfig.java文件(使用Springfox库):
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@Configuration
@EnableSwagger2
public class SwaggerConfig {
@Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any())
.build()
.apiInfo(apiInfo())
.useDefaultResponseMessages(false)
.globalOperationParameters(Collections.singletonList(new ParameterBuilder()
.name("Authorization")
.description("Access token")
.modelRef(new ModelRef("string"))
.parameterType("header")
.required(false)
.build()))
.securitySchemes(Arrays.asList(apiKey()))
.securityContexts(Arrays.asList(securityContext()));
// 添加跨域配置
ApiInfo apiInfo = new ApiInfoBuilder()
.title("API文档")
.description("API文档描述")
.version("1.0")
.build();
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo)
.host("your-host")
.protocols(newHashSet("http", "https"))
.forCodeGeneration(true)
.directModelSubstitute(LocalDate.class, String.class)
.genericModelSubstitutes(ResponseEntity.class)
.useDefaultResponseMessages(false)
.globalOperationParameters(Collections.singletonList(new ParameterBuilder()
.name("Authorization")
.description("Access token")
.modelRef(new ModelRef("string"))
.parameterType("header")
.required(false)
.build()))
.securitySchemes(Arrays.asList(apiKey()))
.securityContexts(Arrays.asList(securityContext()))
.corsConfiguration(new CorsConfiguration()
.allowedOrigins(Arrays.asList("*"))
.allowedMethods(Arrays.asList("GET", "POST", "PUT", "DELETE", "OPTIONS"))
.allowedHeaders(Arrays.asList("Content-Type", "Authorization", "X-Requested-With"))
.allowCredentials(true));
}
}
保存配置文件并重启应用。
方案二:修改Nginx或Apache等Web服务器的配置来实现跨域
如果你使用的是Nginx作为Web服务器,可以在配置文件中添加以下内容:
location / {
if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Allow-Origin' '*' always;
add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS' always;
add_header 'Access-Control-Allow-Headers' 'Content-Type, Authorization, X-Requested-With' always;
add_header 'Access-Control-Allow-Credentials' 'true' always;
add_header 'Content-Length' 0 always;
add_header 'Content-Type' 'text/plain charset=UTF-8' always;
return 204;
}
add_header 'Access-Control-Allow-Origin' '*' always;
add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS' always;
add_header 'Access-Control-Allow-Headers' 'Content-Type, Authorization, X-Requested-With' always;
add_header 'Access-Control-Allow-Credentials' 'true' always;
# 其他配置...
}
如果你使用的是Apache作为Web服务器,可以在.htaccess文件或httpd.conf文件中添加以下内容:
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Methods "GET, POST, PUT, DELETE, OPTIONS"
Header set Access-Control-Allow-Headers "Content-Type, Authorization, X-Requested-With"
Header set Access-Control-Allow-Credentials "true"
</IfModule>
保存更改并重启Web服务器。
这样,Swagger就可以处理跨域问题了。请注意,允许所有来源(*)可能会导致安全问题。在生产环境中,建议将*替换为实际允许访问的域名。
