使用cURL的HTTP请求可以工作，但在Python请求中不工作

Question

我正在尝试使用cURL获取HTTP请求响应，效果很好。然而，当我在Python中使用'requests'包时，我没有得到任何响应（它只是超时，没有返回错误或响应）

我的cURL代码如下所示：

curl 'http://144.126.138.12:17001/api/v0/get-posts-stateless' \
  -H 'authority: bitclout.com' \
  -H 'sec-ch-ua: " Not A;Brand";v="99", "Chromium";v="90", "Google Chrome";v="90"' \
  -H 'accept: application/json, text/plain, */*' \
  -H 'sec-ch-ua-mobile: ?1' \
  -H 'user-agent: Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Mobile Safari/537.36' \
  -H 'content-type: application/json' \
  -H 'origin: https://bitclout.com' \
  -H 'sec-fetch-site: same-origin' \
  -H 'sec-fetch-mode: cors' \
  -H 'sec-fetch-dest: empty' \
  -H 'accept-language: en-US,en;q=0.9' \
  -H 'cookie: datadome=2P0n.mJzUY2hB5B03Tc2hild-xu2AkuX~-mIgJ2VRW-j35yl3njRPJEKTAHgcxyQdxrX-E3vQnr5GSEA~DfK3nyrtPJB1M77Ndccn3BZnf; INGRESSCOOKIE=389b5e3fc60c40d6115364749da12fd0; amp_23345b=c6QQHrpE_pvlOyAXAEKiaE.QkMxWUxpRWIzMVVHWHZ4bUZ0N0piQktIS2pjRjJTMUhZNVNkOEMzWlp5ZTFmQnVEVTVOZnNoYw==..1f6htdgom.1f6htgqqm.4r.0.4r' \
  --data-raw '{"PostHashHex":"","ReaderPublicKeyBase58Check":"BC1YLiUgto51FaPyCPwf2LGGQcCo4qa3XM3KY1zAbK8jCzaDCc4bU27","OrderBy":"newest","StartTstampSecs":null,"PostContent":"","NumToFetch":400,"FetchSubcomments":false,"GetPostsForFollowFeed":false,"GetPostsForGlobalWhitelist":false,"GetPostsByClout":false,"PostsByCloutMinutesLookback":0,"AddGlobalFeedBool":false}' \
  --compressed

当我在cURL代码中使用-v时，我得到以下消息：

我的Python代码使用如下请求：

import requests

headers = {
    'authority': 'bitclout.com',
    'sec-ch-ua': '" Not A;Brand";v="99", "Chromium";v="90", "Google Chrome";v="90"',
    'accept': 'application/json, text/plain, */*',
    'sec-ch-ua-mobile': '?1',

    'content-type': 'application/json',
    'origin': 'https://bitclout.com',
    'sec-fetch-site': 'same-origin',

}

data = '{"PostHashHex":"","ReaderPublicKeyBase58Check":"BC1YLiUgto51FaPyCPwf2LGGQcCo4qa3XM3KY1zAbK8jCzaDCc4bU27","OrderBy":"newest","StartTstampSecs":null,"PostContent":"","NumToFetch":400,"FetchSubcomments":false,"GetPostsForFollowFeed":false,"GetPostsForGlobalWhitelist":false,"GetPostsByClout":false,"PostsByCloutMinutesLookback":0,"AddGlobalFeedBool":false}'

response = requests.post('http://144.126.138.12:17001/api/v0/get-posts-stateless', headers=headers, data=data)
print(response.text)

为什么会发生这种情况？我如何使我的Python代码工作

Answer 1

您可以尝试以下数据：

data = "{\"PostHashHex\":\"\",\"ReaderPublicKeyBase58Check\":\"BC1YLiUgto51FaPyCPwf2LGGQcCo4qa3XM3KY1zAbK8jCzaDCc4bU27\",\"OrderBy\":\"newest\",\"StartTstampSecs\":null,\"PostContent\":\"\",\"NumToFetch\":400,\"FetchSubcomments\":false,\"GetPostsForFollowFeed\":false,\"GetPostsForGlobalWhitelist\":false,\"GetPostsByClout\":false,\"PostsByCloutMinutesLookback\":0,\"AddGlobalFeedBool\":false}"

Answer 2

我运行了精确的代码，大约20秒后得到了（相当大的）响应

响应的长度太大，无法发布2,067,812个字符

如果连接速度较慢（我使用的是每秒下载2Mb的宽带），这可能会花费更长的时间，这可能就是为什么你没有收到响应或者它似乎挂起的原因

我添加了这段代码，并将status_code替换为只需要 还有几秒钟就要跑了。试试这个：

import requests
import time

t1 = time.time()

headers = {
    'authority': 'bitclout.com',
    'sec-ch-ua': '" Not A;Brand";v="99", "Chromium";v="90", "Google Chrome";v="90"',
    'accept': 'application/json, text/plain, */*',
    'sec-ch-ua-mobile': '?1',
    'user-agent': 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Mobile Safari/537.36',
    'content-type': 'application/json',
    'origin': 'https://bitclout.com',
    'sec-fetch-site': 'same-origin',
    'sec-fetch-mode': 'cors',
    'sec-fetch-dest': 'empty',
    'accept-language': 'en-US,en;q=0.9',
    'cookie': 'datadome=2P0n.mJzUY2hB5B03Tc2hild-xu2AkuX~-mIgJ2VRW-j35yl3njRPJEKTAHgcxyQdxrX-E3vQnr5GSEA~DfK3nyrtPJB1M77Ndccn3BZnf; INGRESSCOOKIE=389b5e3fc60c40d6115364749da12fd0; amp_23345b=c6QQHrpE_pvlOyAXAEKiaE.QkMxWUxpRWIzMVVHWHZ4bUZ0N0piQktIS2pjRjJTMUhZNVNkOEMzWlp5ZTFmQnVEVTVOZnNoYw==..1f6htdgom.1f6htgqqm.4r.0.4r',
}

data = '{"PostHashHex":"","ReaderPublicKeyBase58Check":"BC1YLiUgto51FaPyCPwf2LGGQcCo4qa3XM3KY1zAbK8jCzaDCc4bU27","OrderBy":"newest","StartTstampSecs":null,"PostContent":"","NumToFetch":400,"FetchSubcomments":false,"GetPostsForFollowFeed":false,"GetPostsForGlobalWhitelist":false,"GetPostsByClout":false,"PostsByCloutMinutesLookback":0,"AddGlobalFeedBool":false}'

response = requests.post('http://144.126.138.12:17001/api/v0/get-posts-stateless', headers=headers, data=data)

t2 = time.time()

print(response.status_code)

print('time taken:', round(t2-t1, 2), 'seconds')

答复如下：

200
time taken: 3.93 seconds
