uni-app跨域请求设置问题，vue.config.js不管用；manifest.json也无效

// vue.config.js  
module.exports = {  
  devServer: {  
    proxy: {  
      '/api': {  
        target: 'https://gitee.com/',  
        pathRewrite: {  
          '^/api': ''  
        }  
      }  
    },  
  }  
}

// manifest.json  
    "h5": {  
            "devServer": {  
                "proxy": {  
                    "/api": {  
                        "target": "https://gitee.com/",  
                        "pathRewrite": {  
                            "^/api": ""  
                        }  
                    }  
                }  
            }  
    }

uni.request({  
                    url: '/api/dmhsq/photos/raw/master/one.png',  
                    method: 'GET',  
                    success: res => {  
                        console.log(res);  
                    }  
                });
