如何修复 JSON 中的 Expecting 'STRING' 错误

Question

我想在我的应用程序中使用这个json：Json链接：Google JSON

但是当在 https://jsonlint.com/ 检查此 json 时，显示此错误：

Error: Parse error on line 1:
{   predictions: [{         d
--^
Expecting 'STRING', '}', got 'undefined'

我该如何解决这个问题？

Answer 1

您必须输入正确的JSON格式。

以你的例子：

{"prediction":[{"bla":1},{"blabla":2}]}

JSON 的每个键都必须是字符串，因此用双引号引起来。

编辑： 这是具有正确语法的 JSON 片段。

Answer 2

以防万一其他人遇到类似问题，我也遇到了由尾随逗号引起的相同错误，并且 json 需要另一个字段

{
  "case": {
    "field1": "fake value",    
    "field2": "fake value",
    "field3": "fake value",
    "field4": "fake value", < ---- this comma is not allowed
   }
}
