我一直在尝试使用api https://www.duolingo.com/vocabulary/overview访问我在duolingo上学到的单词。问题是,要使用此api,我必须先登录到duolingo(已验证)。我用python提出了一个解决方案,使用requests.sessions()首先将我的凭证发布到登录页面,然后在同一会话中重新路由到词汇表页面。然而,当我试图在flifter中实现这一点时,我遇到了很多问题。我能够成功地将我的凭证发布到登录页面(并获得了成功的200响应),但我无法想出如何使用post请求中的cookie/令牌成功地转到词汇表页面。 下面是我的python代码(为了安全起见,删除了用户名和密码)
import requests
import json
import ast
headers = {'content-type': 'application/json'}
data = {
'identifier': 'username',
'password': 'password',
}
with requests.Session() as s:
url = "https://www.duolingo.com/2017-06-30/login?fields="
# use json.dumps to convert dict to serialized json string
s.post(url, headers=headers, data=json.dumps(data))
r = s.get("https://www.duolingo.com/vocabulary/overview")
cont = r.content.decode('utf-8')
print(cont)
这是带有post请求和非工作get请求的颤振代码
final response = await http.post(
Uri.parse('https://www.duolingo.com/2017-06-30/login?fields='),
headers: <String, String>{
'Content-Type': 'application/json',
},
body: jsonEncode(<String, String>{
'identifier': 'username',
'password': 'password',
}),
); // the post returns a success 200 message
if (response.statusCode == 200) {
print("success");
final resp2 = await http.get(
Uri.parse("https://www.duolingo.com/vocabulary/overview"),
); //the get request is supposed to return a json with all my learned words but is instead returning html of the "404 error page)
}
下面是get请求的输出
<!doctype html><html dir="ltr"><head><title>Duolingo</title><meta charset="utf-8"><meta name="viewport" content="width=device-width,initial-scale=1,user-scalable=no"><meta name="robots" content="NOODP"><meta name="theme-color" content="#eeeeee"><noscript><meta http-equiv="refresh" content="0; url=/nojs/splash"></noscript><meta name="apple-mobile-web-app-capable" content="yes"><meta name="apple-mobile-web-app-status-bar-style" content="black"><meta name="apple-mobile-web-app-title" content="Duolingo"><meta name="google" content="notranslate"><meta name="mobile-web-app-capable" content="yes"><meta name="apple-itunes-app" content="app-id=570060128"><meta name="facebook-domain-verification" content="mwudgypvvgl4fekxjk5rpk3eqg7ykt"><link rel="apple-touch-icon" href="//d35aaqx5ub95lt.cloudfront.net/images/duolingo-touch-icon2.png"><link rel="shortcut icon" type="image/x-icon" href="//d35aaqx5ub95lt.cloudfront.net/favicon.ico"><script src="https://cdn.cookielaw.org/scripttemplates/otSDKStub.js" data-document-langua
我对Flitter非常陌生,而且我从未深入研究过会话和cookies是如何工作的,所以如果我的问题听起来很琐碎,我很抱歉
对于那些访问这个问题寻求答案的人,我最终还是设法找到了答案。这确实非常简单,因为我所要做的就是从post请求中保存令牌,并在get请求的头中再次传递它
