使用转义引号解析 JSON

Question

我试图让我的 JSON 在我的项目中工作，但我卡在json.loads()上。 我不太明白为什么会发生这种情况，因为在我调用相同函数的其他设置上，它正在工作，但这个简单的例子不是。

test_json = """{

def home(request):
    json_data = json.loads(test_json)

    return render(request, 'parsers/home.html', {})

现在，如果我运行它，我会收到一个错误JSONDecode Error at /和Expecting ',' delimiter: line 29 column 60 (char 957) 。 我相信这与正在发生的转义双引号有关。 我试图弄清楚在不更改 JSON 的情况下需要做什么才能使其工作。 我总是可以进行查找和替换，但我不想这样做，因为我的其他代码没有这样做。

谢谢

Answer 1

也许尝试用'替换转义引号（ \"" ），然后再将其传递给json.loads() 。

所以，像这样：

def home(request):
    test_json = test_json.replace('"', "'")
    json_data = json.loads(test_json)
    return render(request, 'parsers/home.html', {})

这可能不是最好的解决方案，但它可以工作。
