数据类型无法使用使用http数据，或者会引起跨域问题
Closed this issue · 2 comments
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，
👋 @weiyy2012，感谢您给 FlyFish 提出了 issue。
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',
},
}
})();
