http协议接口
对于http协议接口，requests库用起来最方便，因此采用requests库来做http协议的接口测试。安装requests：
pip install requests1GET请求示例
输出结果："{"status":1002,"desc":"invilad-citykey"}"
2带参数的GET请求示例
参数：city城市名称
输出结果："{"data":{"yesterday":{"date":"31日星期二","high":"高温27℃","fx":"南风","low":"低温17℃","fl":"","type":"小雨"},"city":"北京","forecast":[{"date":"1日星期三","high":"高温29℃","fengli":"","low":"低温18℃","fengxiang":"南风","type":"晴"},{"date":"2日星期四","high":"高温30℃","fengli":"","low":"低温20℃","fengxiang":"南风","type":"晴"},{"date":"3日星期五","high":"高温30℃","fengli":"","low":"低温22℃","fengxiang":"南风","type":"阴"},{"date":"4日星期六","high":"高温26℃","fengli":"","low":"低温21℃","fengxiang":"南风","type":"中雨"},{"date":"5日星期天","high":"高温26℃","fengli":"","low":"低温20℃","fengxiang":"东风","type":"小雨"}],"ganmao":"感冒易发期，外出请适当调整衣物，注意补充水分。","wendu":"23"},"status":1000,"desc":"OK"}"
假如服务对请求中city的一致性进行校验，header中需要传入Authorization，为city值的md5
输出结果："{"data":{"yesterday":{"date":"31日星期二","high":"高温35℃","fx":"南风","low":"低温25℃","fl":"","type":"晴"},"city":"合肥","forecast":[{"date":"1日星期三","high":"高温30℃","fengli":"","low":"低温24℃","fengxiang":"北风","type":"小雨"},{"date":"2日星期四","high":"高温26℃","fengli":"","low":"低温23℃","fengxiang":"西北风","type":"阴"},{"date":"3日星期五","high":"高温29℃","fengli":"","low":"低温23℃","fengxiang":"东风","type":"多云"},{"date":"4日星期六","high":"高温29℃","fengli":"","low":"低温24℃","fengxiang":"东风","type":"小雨"},{"date":"5日星期天","high":"高温31℃","fengli":"","low":"低温24℃","fengxiang":"东北风","type":"小雨"}],"ganmao":"感冒低发期，天气舒适，请注意多吃蔬菜水果，多喝水哦。","wendu":"26"},"status":1000,"desc":"OK"}"
3POST请求示例
Websocket协议接口
安装websockets库
pip install websockets下面是一个NLP接口的例子，客户端连接服务端，发送文本，接收返回结果，其中文本需要进行base64加密。
import uuid
import websockets
async def send_msg(websocket):
text = "我要查余额"
bs = str(base64.b64encode(text.encode("utf-8")), "utf-8")
sid = uuid.uuid4()
timestamp = str(int(time.time()) * 1000)
msg = "{"app":"test","sn":"123","timeStamp":"" + timestamp + "","version":"1.0.0","data":"" + bs + "","
""sid":"" + str(sid) + ""} "
print(msg)
await websocket.send(msg)
rev_text = await websocket.recv()
print(rev_text)
async def client():
async with websockets.connect("ws://xxx.xxx.com/nlp") as websocket:
await send_msg(websocket)
if __name__ == "__main__":
asyncio.get_event_loop().run_until_complete(client())执行结果示例：{"appid":"test","sn":"123","timeStamp":"1630586234000","version":"0.0","data":"5oiR6KaB5p+l6K+i5L2Z6aKd",sid":"4c6f5a64-2374-4616-9385-376c0d25bc1e"}{"code":"0000","msg":"succ","nlp":"{"sceneKey":"","sid":"d28c7631-54d9-493e-8db8-f67a5ecc2a25","uid":"d28c7631-54d9-493e-8db8-f67a5ecc2a25","text":"我要查询余额",,"semantic":[{"intent":"querybalance","intentName":"查询余额","intentCnxt":"","template":"{Query}余额","score":0.865519,"slots":[]}],"dialog":{"status":0,"uid":"","reaction":{"text":""},"slots":null},"answer":{"answerType":"","text":"","emotion":"","topic":"","topicID":"","type":"","question":{"question":"","question_ws":""}}}","extendData":"","sid":"d28c7631-54d9-493e-8db8-f67a5ecc2a25","last":true}
grpc协议接口
grpc协议需要Python5版本以上，安装所需的库：
pip install grpcio
pip install grpcio-tools下面以虚拟主播服务接口为例，服务使用了grpc双向流进行交互，与服务端建立连接后，会返回一个rtmp地址，推送虚拟主播视频流，向服务端发送文本，会驱动虚拟主播播报文本。
1编写avatar.proto文件
syntax = "proto3";
package protocol;
message AvatarRequest {
string app = 1;
string timestamp = 2;
string version = 3;
string anchorId = 4;
string vcn = 5;
bytes data = 6;
int32 width = 7;
int32 height = 8;
string type=9;
}
message AvatarResponse {
string code = 1;
string msg = 2;
string type = 3;
bytes data = 4;
string status = 5;
string sessionId = 6;
}
service AvatarInteraction {
rpc Interact (stream AvatarRequest) returns (stream AvatarResponse) {
}
}2使用工具生成grpc代码
python-mgrpc_tools.protoc-I.--python_out=.--grpc_python_out=../avatar.proto最终生成avatar_pbpy和avatar_pb2_grpc.py两个文件
3grpc请求示例
将上述两个文件，引入到项目代码中

self.print_res.start()
time.sleep(1)

self.client = client
def run(self):

print(response)
if not self.runStatus:
sys.exit(0)
if response.code != "000000":

sys.exit(0)

client.start()打造自己的测试工具
在编辑器中执行测试，有时候交互性不太友好，因此我们可以打造一个带交互界面的测试工具。QT是跨平台C++库的集合，它实现高级API来访问现代桌面和移动系统的许多方面。这些服务包括定位和定位服务、多媒体、NFC和蓝牙连接、基于铬的web浏览器以及传统的UI开发。PyQt5是一套针对QtV5的全面Python绑定。它被实现为超过35个扩展模块，并使Python可以作为一个替代的应用程序开发语言C++在所有支持的平台上包括IOS和Android。
1安装PyQt5
pip install PyQt5如果要使用像界面进行设计，可以安装QtDesigner形界面开发工具，相关配置可以自行搜索。
