HAProxy 503 服务不可用 - 带标头的 POST

后端未将流量转发到服务器并返回 503 服务不可用。我的服务器需要准确的 URL 和标头。如果未设置标头，服务器将返回 401 未授权，如果未设置 URL，服务器将返回 404 未找到。

我的 cfg 文件

我正在测试如下

import csv
import requests
import time

#url='http://100.82.185.122:32401/services/collector/event' #DIRECT URL 
url='http://100.82.182.73/services/collector/event' #HA Proxy URL
authHeader = {'Authorization': 'Splunk {}'.format('f64e68e1-a6e4-46a1-8fe3-131023886841')}
reader = csv.DictReader(open('overheating_.csv'))
for row in reader: 
    #row['SystemUsage.AggregateUsage'] = 17
    #row['FanSensor.RPMReading'] = 3
    jsonDict = {"index":"dltk-test", "source":"csv", "sourcetype":"all-idrac", "event": row }
    #print (row)
    r = requests.post(url, headers=authHeader, json=jsonDict, verify=False)
    print (r.text)
    time.sleep(1)
