Python 解析urlib请求

我从代码中获得了以下巨大的输出：

urllib.request.urlopen（“https://api...）读取（）

这看起来像一个JSON对象，但它是一个字节对象。我正在调查整个事件的数据。我不知道如何解析所有这些嵌套字典。任何帮助都将不胜感激。我想提取位于端点附近的值112242287903649

内置的

json

模块完全能够解析字节字符串-

导入json
response=urllib.request.urlopen（“https://api/endpoint）改为
jsondat=json.load（响应）

现在，您可以随意使用

jsondat

，并提取所需的嵌套属性

请注意，您也可以使用

请求

模块，尽管在本例中您完全不必这样做，但可以更简单地实现这一点-

导入请求
jsondat=requests.get（“https://api/endpointjson（）

对给定的字节字符串执行

json.loads

您可以使用python中的

json

库将其转换为字典

json.load（您的_字符串）

使用

json

模块加载它并访问您想要的值。另外，使用

请求

可能更方便（即使用

Response.json（）

方法）。
