小白新手，使用request.get_data()獲得post上來的資料，用get取字典的值，目前能獲得post上來的資料，但是字典取不了key值，提示 msg_dict = sms_cord.get("msg")
AttributeError: 'bytes' object has no attribute 'get'
后端之前除錯都是正常的，突然成了這樣，不知道什么原因。
from flask import Flask,request,Response
import json
import base64
#import pymysql
#Flask框架核心功能
app = Flask(__name__)
#conn = pymysql.connect('localhost',user = "root",password ="deng@828416",db = "sms_data")
#cursor = conn.cursor()
#cursor.execute('use sms_data;')
#post引數，路徑最后面加"/",不然會默認get方式
@app.route('/api/msg/',methods=["GET","POST"])
def test1():
# request.get_json 獲取Json 資料
sms_cord = request.get_data()
print("sms_data:" + format(sms_cord))
sms_cord_sms = type(sms_cord)
print(type(sms_cord_sms))
# 通過字典中get獲取指定專案中指定引數
msg_dict = sms_cord.get("msg")
src_dict = sms_cord.get("src")
submitDate_dict = sms_cord.get("submitDate")
messageId_dict = sms_cord.get("messageId")
dest_dict = sms_cord.get("dest")
#使用base64模塊 解碼資料
new_src = base64.b64decode(src_dict.encode('utf-8')).decode("utf-8")
new_msg = base64.b64decode(msg_dict.encode('utf-8')).decode("utf-8")
new_dest = base64.b64decode(dest_dict.encode('utf-8')).decode("utf-8")
print("msg:"+str(msg_dict))
print("src:"+str(src_dict))
print("submitDate:"+str(submitDate_dict))
print("messageId:"+str(messageId_dict))
print("dest:"+str(dest_dict))
#回傳值
result={
"result":"0000"
}
除錯列印：

找到問題了，request.get_data() 獲取的是字串，json.loads轉字典uj5u.com熱心網友回復：
恭喜樓主，賀喜樓主！
