Python中返回错误的JSON键值

我有一个脚本，我希望与NumPy一起使用它在地理数据库中创建要素类。当我发送请求时，我发送到服务器的相关json数据与我的响应不同，因此我无法确定我的键值是什么（如果有的话）。我最终希望有一个键值并循环遍历嵌套项，以用作要素类中的字段

代码：

JSON发送到服务器：

出于测试目的，我至少希望将输出SRNumber写入要素类。

您不需要先选择

SRData

字典吗

parsed_json["SRData"]["La311ServiceRequestNotes"]

究竟什么是

解析的_json

？因为它给了你一个键错误，所以它是一本字典。它的键是什么？

解析的json看起来像什么？您没有在这里发布任何内容：

请求。post（url）

。您没有传递数据或标题。您的

parsed_json

变量包含响应json。你能在你的问题中发布第一个请求的响应吗？@thiruvenkadam：第一个请求可能不会产生任何合理的结果，因为发送的

post

正文将是空的。我希望第一个请求可能会给出完整的元数据，而第二个请求更像是过滤掉的响应。如果没有，解析的

json

应该是用于

response.json（）

而不是

r.json（）

，并且应该在以后的阶段给出。我误解了这一点，但是将我解析的json设置为

parsed\u json=[“SRData”[“la311servicequestnotes”]

抛出

parsed\u json=[“SRData”[“la311servicequestnotes”]

TypeError:列表索引必须是整数，而不是str'

什么是

=['…']

应该做什么？这就是解析的json的问题，我一直无法找出键。
