我正在尝试解析 Json。我已经放了json结构的图像。请看一看。
我收到的错误是：
print("title: "+json_data["title"])
TypeError: string indices must be integers
我的JSON结构如下：

虽然我使用的代码是：
这是我加载json数据的代码。
#assigning path to the url variable
url = link of the server
#Taking response and request from url
r = urllib.request.urlopen(url)
#reading and decoding the data
data = json.loads(r.read().decode(r.info().get_param('charset') or 'utf-8'))
for json_inner_array in data:
for json_data in json_inner_array:
print("title: "+json_data["title"])
print("snippet: ", json_data["snippet"])
print("id: ",json_data["id"])
print("url: ",json_data["url"])
print("score:",json_data['score'])
问题是因为那个 final dict：
{
"hasmore": 1,
"numhits": 1000
}
您的内部循环期望处理包含字典的列表，因此当它遇到该字典时，它会尝试json_data["title"]在“hasmore”键上执行操作。
这是修复版。
import json
datastring = r'''

如果您需要读取最终字典中的数据，只需添加一个else块。例如，
for json_inner_array in data:
if isinstance(json_inner_array, list):
for json_data in json_inner_array:
print("title: "+json_data["title"])
print("snippet: ", json_data["snippet"])
print("id: ",json_data["id"])
print("url: ",json_data["url"])
print("score:",json_data['score'])
else:
print("\nExtra info:")
print("hasmore:", json_inner_array["hasmore"])
print("numhits:", json_inner_array["numhits"])
