uniapp跨域问题解决办法

简介：本文讲解如何解决uniapp和springboot结合时候的的跨域问题。

对于uniapp

编辑manifest.json文件

在最后面加上这段代码

"h5" : {
  		    "devServer" : {
  		         "port" : 8080, //浏览器运行端口
  		          "disableHostCheck" : true, //设置跳过host检查
  		          "proxy" : {
  		              "/api" : {
  		                  "target" : "http://localhost:8081", //目标接口域名
  		                   "changeOrigin" : true,  //是否跨域
  		                   "secure" : false,  // 设置支持https协议的代理
  											 "pathRewrite":{"^/api":""}
  		             }
  		        }
  		    }
  		}

完整的是这个样子的

{
  "name": "LoginAndRegister",
  "appid" : "",
  "description" : "",
  "versionName" : "1.0.0",
  "versionCode" : "100",
  "transformPx" : false,
  /* 5+App特有相关 */

      "usingComponents" : true,
      "nvueStyleCompiler" : "uni-app",
      "compilerVersion" : 3,
      "splashscreen" : {
          "alwaysShowBeforeRender" : true,
          "waiting" : true,
          "autoclose" : true,
          "delay" : 0
      },
      /* 模块配置 */

      /* 应用发布信息 */
      "distribute" : {
          /* android打包配置 */
          "android" : {
              "permissions" : [

                  "<uses-feature android:name=\"android.hardware.camera.autofocus\"/>",
                  "<uses-permission android:name=\"android.permission.ACCESS_NETWORK_STATE\"/>",
                  "<uses-permission android:name=\"android.permission.CAMERA\"/>",
                  "<uses-permission android:name=\"android.permission.GET_ACCOUNTS\"/>",

                  "<uses-feature android:name=\"android.hardware.camera\"/>",
                  "<uses-permission android:name=\"android.permission.WRITE_SETTINGS\"/>"
              ]
          },
          /* ios打包配置 */
          "ios" : {},
          /* SDK配置 */

      }
  },

  },

      "enable" : false
  },
  "vueVersion" : "2",
  		"h5" : {
  		    "devServer" : {
  		         "port" : 8080, //浏览器运行端口
  		          "disableHostCheck" : true, //设置跳过host检查
  		          "proxy" : {
  		              "/api" : {
  		                  "target" : "http://localhost:8081", //目标接口域名
  		                   "changeOrigin" : true,  //是否跨域
  		                   "secure" : false,  // 设置支持https协议的代理
  											 "pathRewrite":{"^/api":""}
  		             }
  		        }
  		    }
  		}

}

对于springboot

添加CorsConfig配置文件

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@Configuration
public class CorsConfig {
    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                // 允许来自本地的8080端口发起的跨域请求
                registry.addMapping("/api/**")
                    .allowedOrigins("*")
                    .allowedMethods("GET", "POST", "PUT", "DELETE")
                    .allowCredentials(true).maxAge(3600);
            }
        };
    }
}
