Python 迭代多个json行

我有一个包含数百行JSON的文件。我编写了一个小python脚本，可以提取一些数据，但它只适用于一行。我现在想知道如果文件中有多行，如何循环遍历所有行。 到目前为止，我得到的是：

import json
from pprint import pprint

"""with open('1st_run_fixed.json') as f:"""
with open('fixed.json') as f:
    data = json.load(f)

    print "--------------------------------------------";
    """get number of characters"""
    nchar = data["frames"]["frame"]["lps"]["lp"]["ncharacter"];
    print "Got "+nchar+" characters";
    for x in range (1,int(nchar)+1):
        x = str(x);
        print data["frames"]["frame"]["lps"]["lp"]["characters"]["char"+x]["code_ascii"]+"    "+data["frames"]["frame"]["lps"]["lp"]["characters"]["char"+x]["confidence"];
    print "--------------------------------------------";

适用于以下数据：

当我运行大文件时

我有一个包含数百行JSON的文件

不，你没有，这就是问题所在

---

数百个JSON文本不是有效的JSON文件。一个有效的JSON文件只是一个文本。这就是

json.load

返回错误的原因

---

数百个JSON文本，每一个文本正好放在一行上，中间有换行符，是其他格式（如JSONlines或NDJ）的有效文件。它仍然不是有效的JSON文件，因此您不能使用

JSON.load

，但您可以使用JSONlines或NDJ库，或者像这样解析它：

with open('fixed.json') as f:
    for line in f:
        data = json.loads(line)
        # do stuff

对于编写JSONlines文件，同样，您可以使用JSONlines库，或者如果不指定非默认值

请确保\u ascii

或

缩进

参数，只需写出

JSON.dumps（data）+“\n，则可以确保每个JSON文本没有默认情况下实际发生的嵌入换行符

用于每个值

---

但是数百个JSON文本，每一个都占用多行，并不是一个有效的文件

这实际上是：

注意：与

pickle

和

marshal

不同，JSON不是框架协议，因此尝试使用相同的fp重复调用

dump（）

序列化多个对象将导致JSON文件无效

“非框架协议”的意思基本上是格式不明确。例如，如果您先做了一个

json.dump（2，f）

，然后做了一个

json.dump（3，f）

，那么您在文件中得到的是

23

。这与您从

json.dump（23，f）

获得的内容相同

---

如果您可以将文件修复为有效的文件，如JSONlines，那么这就是简单的解决方案

---

如果你不能

在标准化之前，有一个“JSON文档”的概念，它基本上意味着一个JSON文本，它要么是数组，要么是对象。JSON文档流并不含糊

由于这不是一种标准格式，您可能找不到它的解析器，所以您必须自己编写一个

一种方法是使用

json

模块中的方法。这将尝试解码一个JSON文本，后面可能有额外的内容，并将索引返回给额外的内容。在您的例子中，这是下一个JSON文档

由于这种大小的数百个对象并不太大，因此只需将整个文件读入内存，然后对其进行解析可能更简单，因此我们不必担心缓冲：

with open('fixed.json') as f:
    contents = f.read()
decoder = json.JSONDecoder()
while contents:
    data, idx = decoder.raw_decode(contents)
    do_stuff(data)
    contents = contents[idx:].lstrip()

---

请记住，只有当您的文件是JSON文档流（即顶级值始终是数组或对象）时，这才有效。此外，如果您手动编辑这些文件，与JSONlines不同，JSONlines可以跳过一个错误文本并继续解析其余的文本，现在有了从错误中恢复的方法，因为您不知道下一个文档从何处开始。

感谢您的回复，但您的建议

json.loads（line）

建议似乎不起作用：）我得到了一份工作error@cerr首先，答案并不是说，它解释了为什么除非你修复数据，否则这样做是行不通的不是任何人都可以调试您的。在这种情况下，我可以猜测您会遇到什么错误，因为我已经知道为什么该代码对您的数据不起作用，但一般来说，如果您希望人们帮助您，您需要向他们提供足够的信息来帮助。我理解，但我确实得到了

回溯（最近一次调用）：\n文件“read.py”，第9行，在加载\n返回\n默认\u解码器.decode中

问题是：我有一个日志文件，其中包含大量信息和一些交错的JSON行。然后我将JSON行变灰，并将它们放在一个文件中，以提取我感兴趣的数据…@cerr向我展示了一部分甚至不包含错误类型或消息的回溯，这不是很有帮助，但也没关系。第一个你的文件中的e不是JSON文本。因此，如果你调用

JSON.load（line）

，你会得到一个

JSONDecodeError

。你拥有的不是JSONlines文件，就像它是一个JSON文件一样，所以尝试将其作为一个文件进行解码将失败。我不知道如何解释这一点。可能是重复的
