python-requests相當於curl的--data-binary？

Question

Curl可以選擇按照--data-binary option的原樣發送文件。

當測試Qualys WAS API，下面的curl命令作品：

curl -u "username:password" -H "content-type: text/xml" -X "POST" --data-binary @- "https://qualysapi.qualys.com/qps/rest/3.0/search/was/webapp" < post.xml 

post.xml：

<ServiceRequest><filters><Criteria operator="CONTAINS" field="name">PB - </Criteria></filters></ServiceRequest> 

使用Python的請求模塊，我不斷收到一個HTTPError：415客戶端錯誤：不支持的媒體類型。

import requests 
url = 'https://qualysapi.qualys.com/qps/rest/3.0/search/was/webapp' 
payload = '<ServiceRequest><filters><Criteria operator="CONTAINS" field="name">PB - </Criteria></filters></ServiceRequest>' 
headers = {'X-Requested-With': 'Python requests', 'Content-type': 'application/json'} 
r = requests.post(url, data=payload, headers=headers, auth=('username', 'password')) 

當試圖提交文件文件參數時，它也以415錯誤結束。

import requests 
url = 'https://qualysapi.qualys.com/qps/rest/3.0/search/was/webapp' 
payload = '<ServiceRequest><filters><Criteria operator="CONTAINS" field="name">PB - </Criteria></filters></ServiceRequest>' 
headers = {'X-Requested-With': 'Python requests', 'Content-type': 'application/json'} 
r = requests.post(url, data=payload, headers=headers, auth=('username', 'password')) 

我設置這個的原因是將其合併到qualysapi Python package。

Answer 1

原來我應該有頭是

headers = {'X-Requested-With': 'Python requests', 'Content-type': 'text/xml'}
