1. 问题说明
soap请求方法getPosterityNodes时出现504错误。
504错误是什么
- 使用soap协议进行ws请求时，服务端超时返回，无响应

使用Python进行soap请求，观察结果，测试脚本如下
from suds.client import Client
from suds.xsd.doctor import ImportDoctor, Import
from suds.wsse import *
import datetime
url = 'http://st01-noah-matrix86.st01:8810/olive/index.php?r=Tree/infoWS/ws'
doctor = ImportDoctor(imp)
client = Client(url, doctor = doctor)
security = Security()
token = UsernameToken('admin', 'admin')
security.tokens.append(token)
client.set_options(wsse=security)
print(client) #打印输出ws提供的接口描述信息(wsdl)
starttime = datetime.datetime.now()
re = client.service.getNodeById(18) #调用ws方法getNodeById(int)
re = client.service.getNodePathById() #调用ws方法getNodePathById(int)
re = client.service.getPosterityNodeIds(18,1) #调用ws方法getPosterityNodeIds(int,int),获取指定节点的所有孩子节点的id
re = client.service.getPosterityNodes(22,1) #调用ws方法getPosterityNodes(int,int),获取指定节点的所有孩子节点详细信息
print("获取的节点内容：",re)
endtime = datetime.datetime.now()
print ("运行时间：",(endtime - starttime).seconds) #输出调用方法运行时间4. 测试结果
参数：nodeId=0时，可以正常返回。
调用方法 返回结果 运行时间 getNodeById root节点 0 getPosterityNodeIds 480759个孩子节点 119 getPosterityNodes None 7
参数：nodeId=1时，可以正常返回。
调用方法 返回结果 运行时间 getNodeById BAIDU节点 0 getPosterityNodeIds 476727个孩子节点 131 getPosterityNodes None 7
参数：nodeId=3时，504错误出现。
调用方法 返回结果 运行时间 getNodeById BAIDU_PS_www(产品线节点) 0 getPosterityNodeIds 61720个孩子节点 18 getPosterityNodes 无返回 504错误
参数：nodeId=22时，可以正常返回。
调用方法 返回结果 运行时间 getNodeById BAIDU_PS_www_online_rs_build_rs-build-rscompact.www.all(叶子节点) 0 getPosterityNodeIds 1个孩子节点(包括自己) 0 getPosterityNodes 可以正常返回自身的详细信息 0
参数：nodeId=18时，可以正常返回。
调用方法 返回结果 运行时间 getNodeById BAIDU_PS_www_online_rs_build(服务节点) 0 getPosterityNodeIds [18, 12055, 22, 23, 24, 200118829]共6个节点 0 getPosterityNodes 可以正常返回6个节点的详细信息 0
5. 总结
- root节点和BAIDU公司节点在获取孩子节点的详细信息时可以正常返回，但是返回为None
- 测试节点id = 3，该节点是一产品线节点，下面有60000多孩子节点，获取所有孩子节点id耗时18s，获取所有孩子节点详细信息时，出现504错误
- 其余测试节点，18和22，下面的孩子节点个数比较少，都可以按时正常返回结果，并且结果符合预期
故：产生504错误的原因可能是大量查询操作耗时太久导致ws服务端未能按时返回结果导致504错误。
