Question

在JSON解析函数中转义引号时，我遇到了一个常见问题。如果存在转义引用，在这种情况下＆＃39; test＆＃34;＆＃39;，则会导致以下错误＆＃39;语法错误：JSON解析错误：未终止字符串＆＃39;。

var information = JSON.parse('[{"-1":"24","0":"","1":"","2":"","3":"0.0000","4":"","5":"0.00","6":"0.00","7":"1.00","8":"0","9":"false","10":"false","11":[""],"12":"","13":"","14":"test\""}]');

JSON Lint将JSON验证为有效。

Answer 1

你必须加倍逃避它，就像"test\\""

一样

＆＃13;

var information = JSON.parse('[{"-1":"24","0":"","1":"","2":"","3":"0.0000","4":"","5":"0.00","6":"0.00","7":"1.00","8":"0","9":"false","10":"false","11":[""],"12":"","13":"","14":"test\\""}]');

document.body.innerHTML = '<pre>' + JSON.stringify(information, null, 4) + '</pre>';

＆＃13;

第一个反斜杠会转义javascript字符串文字中的第二个反斜杠。第二个反斜杠会转义JSON字符串文字中的引号。

所以它被解析了两次，需要两次转义。

因此，即使它是有效的JSON，您也需要一个转义，以逃避JSON中使用的转义的javascript字符串文字。

Answer 2

    var information = JSON.parse('[{"-1":"24","0":"","1":"","2":"","3":"0.0000","4":"","5":"0.00","6":"0.00","7":"1.00","8":"0","9":"false","10":"false","11":[""],"12":"","13":"","14":"test\\""}]');

让doubleslash为我工作......至少在控制台中......尝试一下..

Answer 3

我通过使用@IgnoreJson通过@RestController在Spring Boot应用程序中解决了此问题

--------- class book ---------------
@OneToMany(mappedBy = "book")
private Set<Chapitre> chapitres = new TreeSet<>();
--------- class chapitre -----------
@ManyToOne(cascade = CascadeType.MERGE)
@JsonIgnore
private Book book;

Answer 4

以下是问题：在最后一个对象数组

中使用\'代替\“

\"

\'
