我将curl请求转换为Python请求调用时遇到问题：
以下是curl调用的外观：（摘自：http : //developers.payu.com/en/restapi.html#creating_new_order_api）
curl -X POST https://secure.payu.com/api/v2_1/orders \
-H "Content-Type: application/json" \
-H "Authorization: Bearer 3e5cac39-7e38-4139-8fd6-30adc06a61bd" \
-d '{
"notifyUrl": "https://your.eshop.com/notify",
"customerIp": "127.0.0.1",
"merchantPosId": "145227",
"description": "RTV market",
"currencyCode": "PLN",
"totalAmount": "21000",
"products": [
{
"name": "Wireless Mouse for Laptop",
"unitPrice": "15000",
"quantity": "1"
},
{
"name": "HDMI cable",
"unitPrice": "6000",
"quantity": "1"
}
]
}'
这是我在请求中写的：
import json
import requests
headers = {
'Content-Type': 'application/json',
'Authorization': 'Bearer 3e5cac39-7e38-4139-8fd6-30adc06a61bd',
}
data = {
"notifyUrl": "https://your.eshop.com/notify",
"customerIp": "127.0.0.1",
"merchantPosId": "145227",
"description": "RTV market",
"currencyCode": "PLN",
"totalAmount": "21000",
"products": [
{
"name": "Wireless Mouse for Laptop",
"unitPrice": "15000",
"quantity": "1"
},
{
"name": "HDMI cable",
"unitPrice": "6000",
"quantity": "1"
}
]
}
resp2 = requests.post('https://secure.payu.com/api/v2_1/orders', headers=headers, json=data)
print(resp2.json())
卷曲作为响应打印出来：
{"orderId":"V6GRPMNRLR160429GUEST000P01","status":{"statusCode":"SUCCESS"},"redirectUri":"https://secure.payu.com/pl/standard/co/summary?sessionId=HtnLqVtBJ5tcOKG2nX03TKwAXOYtXPHe&merchantPosId=145227&timeStamp=1461948331350&showLoginDialog=false&apiToken=9f31fcd1d0d1c5fde8aa57c2b16b5d6bbdfe81543a5f6a12cd39955a487fdaab"}
而python请求：

有谁知道为什么它不能处理请求？谢谢
该站点以302状态代码响应，其中包括Location标头：
>>> resp = requests.post('https://secure.payu.com/api/v2_1/orders', headers=headers, json=data)
>>> resp.history
[<Response [302]>, <Response [302]>]
>>> resp.history[0].headers['location']
'https://secure.payu.com/pl/standard/co/summary?sessionId=rrQ97fR2bxQJhUqCDORCbRa0uA4WlxJi&merchantPosId=145227&timeStamp=1461950205252&showLoginDialog=false&apiToken=f3599eca78ad55a16d84608e69f3ac7458b782598b064b337be07e8bd6c2c1d5'
>>> resp.history[0].text
u'{"orderId":"Z9W2H77TVD160429GUEST000P01","status":{"statusCode":"SUCCESS"},"redirectUri":"https://secure.payu.com/pl/standard/co/summary?sessionId=rrQ97fR2bxQJhUqCDORCbRa0uA4WlxJi&merchantPosId=145227&timeStamp=1461950205252&showLoginDialog=false&apiToken=f3599eca78ad55a16d84608e69f3ac7458b782598b064b337be07e8bd6c2c1d5"}'
您可以通过查看response.history包含先前请求的列表来查看重定向历史记录（就像我在上面所做的那样）。resp.history[0]是这里的最初回应。请参阅文档中的重定向和历史记录。
请注意，数据是正确的有初始响应。
当您使用任何 Accept-Encoding标题时，网站都会执行此操作；如果添加，您将得到相同的结果
-H "Accept-Encoding: gzip, deflate"
到curl命令，或通过将相同的标头（具有任何值）添加到提供的payu.apiari.io控制台中（单击标头，然后添加Accept-Encoding标头并为标头添加一个值）。
您应该将此视为站点中的错误，因为指定header是完全正常的事情。实际上，如果您自己忽略该标头，则Pythonhttplib库（由间接使用requests）为该标头设置默认值，因此requests甚至无法关闭该标头。因此，我已将此错误报告给PayU。
作为一种变通方法，您可以使用response.history[0]引用，或者更好的是，告诉请求不要一开始就遵循重定向：
>>> resp = requests.post('https://secure.payu.com/api/v2_1/orders', headers=headers, json=data, allow_redirects=False)
>>> resp.json()
{u'orderId': u'NBWTP5WNKK160429GUEST000P01', u'status': {u'statusCode': u'SUCCESS'}, u'redirectUri': u'https://secure.payu.com/pl/standard/co/summary?sessionId=PcvceJHf5En60Dier5gKxCyExiva4qh0&merchantPosId=145227&timeStamp=1461950329704&showLoginDialog=false&apiToken=5962ef901010ca4f8ef6491619217c060f4d53ed0d8e4eadb513d4e0811fc992'}
但是请注意，忽略302可能会干扰正常的状态代码，我看到302可能表示需要其他安全信息。
