py调用webservice array数组老是为空的问题

python webserbice

server

import logging
from flask import Flask
from spyne.application import Application
from spyne.protocol.soap import Soap11
from spyne.server.wsgi import WsgiApplication
from werkzeug.serving import run_simple
from werkzeug.middleware.dispatcher import DispatcherMiddleware
from apps import HelloWorldService, HelloWorldService2


application = Application([HelloWorldService, HelloWorldService2],
                          'xxxxx',
                          in_protocol=Soap11(validator='lxml'),
                          out_protocol=Soap11())


wsgi_application = WsgiApplication(application)
flask_app = Flask(__name__)
application = DispatcherMiddleware(flask_app.wsgi_app, {
    'xxxxx': wsgi_application,
})


if __name__ == '__main__':

    host = '127.0.0.1'
    port = 8902
    logging.basicConfig(level=logging.DEBUG)
    # 指定日志记录器的名称，设置日志记录级别
    logging.getLogger('spyne.protocol.xml').setLevel(logging.DEBUG)
    logging.info("wsdl is at: http://localhost:8902//xxxxx?wsdl")
    run_simple(host, port, application)

然后是 apps 这是个人组织的目录架构

import json
from spyne.decorator import rpc
from spyne import ServiceBase
from spyne import Integer, Unicode, Array, ComplexModel, Iterable, String


class Person(ComplexModel):
    name = Unicode
    age = Integer


class PeopleResponse(ComplexModel):
    name = Person
    message = Unicode


# step2: 定义服务
class HelloWorldService(ServiceBase):
    @rpc(Unicode, Integer, _returns=Iterable(Unicode))
    def say_hello(self, name, times):
        for i in range(times):
            yield "Hello %s, It's the %s time to meet you." % (name, i + 1)

    @rpc(String, _returns=Iterable(Unicode))
    def say_hello_1(self, persons):
        print(f'-------say_hello_1({persons})--------')
        if not persons:
            yield 'None'
        persons = json.loads(persons)
        for person in persons:
            print('name is : %s, age is %s.' % (person["name"], person["age"]))
            yield 'name is : %s, age is %s.' % (person["name"], person["age"])


class HelloWorldService2(ServiceBase):
    @rpc(String, _returns=Iterable(Unicode))
    def say_hello_2(self, persons_array):
        print('参数', persons_array)
        if not persons_array:
            yield 'None'
        persons_array = json.loads(persons_array)
        for person in persons_array:
            yield person

    @rpc(Person, _returns=PeopleResponse)
    def say_hello_3(self, person):
        if not person:
            return {}
        else:
            # return PeopleResponse(name=People(**person))
            return {
                "name": person,
                "message": 'name is : %s, age is %s.' % (person.name, person.age)
            }

    @rpc(Array(String), _returns=Iterable(String))
    def say_hello_5(self, a_list):
        if not a_list:
            return {}
        for i in a_list:
            yield i  

client 用zeep suds不维护了

from zeep import Client

host = '127.0.0.1'
port = 8902

# 创建zeep客户端
client = Client(f'http://{host}:{port}/xxxxx?wsdl')

# 调用say_hello方法
persons = client.service.say_hello('zhangsan', 2)
print(persons)
print('-' * 50)

# 调用接受字典作为参数的方法
pers = {"name": "张三", "age": 23}  # 注意：这里使用了普通的字符串而不是Unicode字符串（在Python 3中它们是相同的）
result = client.service.say_hello_3(pers)  # 如果方法期望关键字参数，可以使用**来解包字典
print(result)
print('-' * 50)

import json
persons_list = [{'name': 'zhangsan', 'age': 23}, {'name': 'lisi', 'age': 24}]
person_str_result = client.service.say_hello_1(json.dumps(persons_list))  # 假设这是正确的方法名
print(person_str_result)
print('=' * 20)

# 调用需要stringArray的方法
persons_str_list = json.dumps(['lisicvbcvb', 'zhangsan'])
person_str_result = client.service.say_hello_2(persons_str_list)  # 假设这是正确的方法名
print(person_str_result)
print('=' * 20)


a_list = ['s', 'b', 'g']
fa = client.type_factory("ns0")
arr = fa.stringArray(a_list)
ress = client.service.say_hello_5( arr)
print(ress)

有个问题就是，client 传复杂结构的数据比如列表和字典 server端老是收到为空的参数
解决：
fa = client.type_factory("ns0")
arr = fa.stringArray(a_list)
要根据文档的参数类型进行一个转换 我看网上说会自动转换 但是没有转 不知道问题在哪 有大佬看到可以帮我解答一下 跪谢
