如何使用带有Request-promise的自定义cookie发送请求
如何使用带有Request-promise的自定义cookie发送请求
提问于 2018-08-18 23:55:18
我正在开发一个打印应用程序，我需要从受保护的资源中获取一些数据。我登录的唯一方式是使用浏览器，所以我使用phantom作为浏览器。我设法登录并获得cookie，但我不知道如何使用cookies与请求-承诺与我登录时获得的cookie一起发送请求。
以下是我的简化代码：
import * as phantom from "phantom";
import * as requestPromise from "request-promise-native";
requestPromise.defaults({ rejectUnauthorized: false });
(async function () {
const instance = await phantom.create([
"--ignore-ssl-errors=true",
"--cookies-file=cookies.txt",
"--web-security=false",
"--ssl-protocol=any"
]);
const page = await instance.createPage();
const status = await page.open("http://localhost:3000/auth/login-html");
console.log("status", status);
let result = await page.evaluate(() => {
(document.getElementById("username") as HTMLInputElement).value = "test@email.com";
(document.getElementById("password") as HTMLInputElement).value="password";
(document.getElementById("login") as HTMLElement).click();
return true;
});
// Get the cookies
let cookies = await page.property("cookies");
console.log(cookies)
/** [{ domain: 'my-app-resource-domain.com',
httponly: true,
name: 'ticket',
path: '/',
secure: false,
value: '6823a-78c0a4ee82c0' },
{ domain: 'my-app-resource-domain.com',
httponly: true,
name: 'JSESSIONID',
path: '/',
secure: false,
value: '9CB8396A05ABA178' }] **/
let cookiesSring = getStringCookies(cookies) // "ticket=6823a-78c0a4ee82c0&JSESSIONID=9CB8396A05ABA178"
requestPromise.cookie(cookiesSring );
// Send request to get data from protected resource
let res = await requestPromise.get("http://my-app-resource-domain.com/api/get-charts")
})();回答 1

文档中对此非常不清楚，但是cookie函数实际上只是解析并返回一个cookie字符串作为对象。它不会将cookie设置为在请求中发送。
您有两个选择。您可以使用tough-cookie创建cookie jar并将其作为shown in the official documentation包含在选项中，也可以直接将cookie包含在标头中。
使用cookie jar
import * as requestPromise from "request-promise-native";
import { Cookie } from "tough-cookie";
// ...
const pageCookies = await page.property("cookies");
// rename the "httponly" property to "httpOnly" since that's what
// tough-cookie expects
const cookies = pageCookies.map(pageCookie => {
const cookie = { ...pageCookie };
cookie.httpOnly = pageCookie.httponly;
delete cookie.httpOnly;
return new Cookie(cookie);
});
const cookieJar = requestPromise.jar();
// Set the cookies to apply only to my-app-resource-domain.com
cookies.forEach(cookie =>
cookieJar.setCookie(cookie, "http://my-app-resource-domain.com/")
);
const options = {
uri: "http://my-app-resource-domain.com/api/get-charts",
jar: cookieJar
};
const res = await requestPromise.get(options);使用标头
import * as requestPromise from "request-promise-native";
import * as querystring from "querystring";
// ...
const pageCookies = await page.property("cookies");
// pluck the name and value from the page cookies into
// key-value pairs in an object
const cookieObjects = pageCookies.reduce((acc, cookie) => {
acc[cookie.name] = cookie.value;
return acc;
}, {});
// stringify the cookies to the familiar "cookie=value; cookie2=value" format
const cookieString = querystring.stringify(cookieObjects, "; ");
const options = {
uri: "http://my-app-resource-domain.com/api/get-charts",
headers: {
Cookie: `${cookieString};`
}
};
const res = await requestPromise.get(options);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
