使用这种方法请求
let loadDataCource = new dv.adapter.DataSource("http", {
url: "",
method: "", // GET POST
interval: "", // 定时拉取
vars: "{}", //json
headers: "",
apiSuccessCode: "200",
apiSuccessCodeField: "code",
getDataField: "data"
});
loadDataCource.load({ //可以替换掉初始化的传参 }, (data) => {}, () => {})
env.js文件修改,增加代理
window.DATAVI_ENV = (function() {
return {
debug: true,
apiDomain: 'http://127.0.0.1:9090',
componentsDir: 'lcapWeb/www/components',
useHttpProxy: true,
screenAPI: {
httpProxy:
'https://docp-ops.cloudwise.com/gateway/lcap-data-server/api/dataplateform/apiProxy',
},
}
})();
问题一:数据类型无法使用使用http数据 step1: 配置: /lcapWeb/lcapWeb/www/web/screen/config/env.js useHttpProxy: true, step2: 应用开发中,数据类型选择http数据 step3:输入http地址 弹窗显示: SyntaxError: Failed to execute 'open' on 'XMLHttpRequest': Invalid URL;没有发起http请求
预期 不弹窗,发起http请求
问题二:会引起跨域问题 step1: 配置: /lcapWeb/lcapWeb/www/web/screen/config/env.js useHttpProxy: false, step2: 应用开发中,数据类型选择http数据 step3:输入http地址 弹窗显示: http请求不成功,提示跨域Response to preflight request doesn't pass access control check: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.
预期 http请求成功,
