Bertha 。 2023-06-17 13:52 23阅读 0赞

1.eval方法即可【字典字符串转字典】  
file\_content = eval(file\_content)

2.urllib.request.Request发送post请求，发送json参数

from urllib.request import Request, urlopen
    import json
    
    调用代码片段：
    url = 'http://www.abc.1201t.com/api-sss/tdd/woRegulationCreate'
        header = {
            'tokenStr': "MTc2OF90b2tlbl8xNTQxNDg5NjA3MzYxLCwsMTU0MTQ4OTYwNzM2MQ==",
            'Content-Type': 'application/json'
        }
        post_data = {"evType": "曳引与强制驱动电梯",
                     "groupName": "半月保养(国际)",
                     "memo": "hui",
                     "count": "31/31",
                     "regullations":
                         [
                             {"name": "清洁",
                              "desc": "机房清洁",
                              "state": "1"}
                         ]
                     }
        # post_data = urlencode(post_data).encode('utf-8')
    
        req = Request(url=url, data=json.dumps(post_data).encode('utf-8'), headers=header, method='POST')
        file_content = urlopen(req).read().decode('utf-8')
        print(type(file_content))
        print(file_content)

亲测可行
