json.loads加载JSON数组后遍历出现字符逐个输出问题求助

Ah, I see the issue here—you're accidentally turning your JSON array into a string literal, which is why iterating over it gives individual characters instead of the objects you expect. Let's break this down:

The Root Cause #

Look at this line in your code:

obj = json.loads("\"" + line[11:-7] + "\"")

You're wrapping the truncated line[11:-7] content in extra double quotes. Let's say line[11:-7] is already a valid JSON array string like this:

[{"ip":"66.102.8.203","sg_user_id":7018833,...}]

By adding those surrounding quotes, you're turning it into a string literal instead of a JSON array:

"[{"ip":"66.102.8.203","sg_user_id":7018833,...}]"

When json.loads() parses this, it returns a single string (not a list). So when you loop over obj, you're iterating over each character in that string—hence the broken output you're seeing.

The Fix #

Simply remove the manual surrounding quotes and parse the truncated line directly:

with open(filtered_aws_logs_path) as input:
    for i, line in enumerate(input):
        obj = json.loads(line[11:-7])  # No extra quotes here
        print("response: " + str(i))
        print(obj)
        for json_item in obj:
            print(json_item)
        break

Quick Verification #

If you add print(type(obj)) before your loop:

• Before the fix: It will output <class 'str'> (confirming it's a string)
• After the fix: It will output <class 'list'> (confirming it's the JSON array you expected)

Now when you iterate over obj, you'll get each dictionary in the array instead of individual characters.
