我在以下行中遇到异常：

例外是：
Expected literal value at character 2 of value.
答案 0 :(得分：3)
根据json.org（必须有资格作为可信/官方来源），JSON string（在您的JSON array中使用，作为名称和值），必须使用双引号引用：
string 是零个或多个Unicode字符的序列，用双引号括起来，使用反斜杠转义符。
也许你或其他人误读这意味着你应该使用反斜杠转义而不是双引号？
它的真正含义是您必须在"周围使用双引号（string）。如果要使用十六进制形式的双引号，反斜杠，控制字符或unicode字符，则反斜杠字符仅用作引用字符串中的转义字符，作为您的一部分string。
您可以在Ecma 404 standard document中阅读有关JSON格式的更多信息，但我怀疑您需要的不仅仅是json.org中的语法和示例。
在任何情况下，根据JSON格式，您的输入无效。您获得的异常是正确的，并且是此输入的预期。
以下是您可读且正确的整个JSON数组：

正如许多其他人已经指出的那样，您可以使用正则表达式或类似方法轻松解决此问题，将所有\字符替换为"字符。

您的JSON无效。我不知道你为什么用\或\\。用“或”替换那些。

您可以测试您的json是否正确。
网站：
答案 2 :(得分：0)
你JSON看起来无效。
不确定源的来源，但String应该用双引号括起来，而不是反斜杠。
E.g。
[
{
"DoctorId":3,
"UserId":0,
...
}
]
答案 3 :(得分：0)
您的JSON无效。以下链接提供了有效JSON语法的示例。 Valid JSON请注意使用双引号。虽然在JavaScript中交替使用单引号和双引号是完全正确的，但单引号在JSON中无效。如果您已经完成了任何程度的Java编程，那么您必须在Strings中转义双引号字符这一事实应该是显而易见的。
