TypeError:使用Python解析JSON时，字符串索引必须是整数? [英] TypeError: string indices must be integers while parsing JSON using Python?

问题描述

我现在感到困惑，为什么我无法解析此JSON字符串.类似的代码可以在其他JSON字符串上正常工作，但不能在此字符串上正常工作-我正在尝试解析JSON字符串并从JSON提取脚本.

I am confuse now why I am not able to parse this JSON string. Similar code works fine on other JSON string but not on this one - I am trying to parse JSON String and extract script from the JSON.

下面是我的代码.

for step in steps:
    step_path = '/example/v1' +'/'+step

    data, stat = zk.get(step_path)
    jsonStr = data.decode("utf-8")
    print(jsonStr)
    j = json.loads(json.dumps(jsonStr))
    print(j)
    shell_script = j['script']
    print(shell_script)

所以第一个print(jsonStr)将打印出这样的内容-

So the first print(jsonStr) will print out something like this -

{"script":"#!/bin/bash\necho Hello world1\n"}

第二个print(j)将打印出类似这样的内容-

And the second print(j) will print out something like this -

{"script":"#!/bin/bash\necho Hello world1\n"}

然后没有打印出第三张照片，它给出了此错误-

And then the third print doesn't gets printed out and it gives this error -

Traceback (most recent call last):
  File "test5.py", line 33, in <module>
    shell_script = j['script']
TypeError: string indices must be integers

所以我想知道我在这里做错什么了吗?

So I am wondering what wrong I am doing here?

我已经使用了与上面相同的代码来解析JSON，并且效果很好.

I have used same above code to parse the JSON and it works fine..

推荐答案

尝试将j = json.loads(json.dumps(jsonStr))替换为j = json.loads(jsonStr).
