如何测试以下JSON
文件的正确性?
在命令行上使用basex
:
thufir@dur:~/json$
thufir@dur:~/json$ ls
formatted.json raw.json
thufir@dur:~/json$
thufir@dur:~/json$ basex
BaseX 9.0.1 [Standalone]

> CREATE DATABASE db raw.json
"/home/thufir/json/raw.json" (Line 1): Content is not allowed in prolog.
>
> CREATE DATABASE db formatted.json
"/home/thufir/json/formatted.json" (Line 1): Content is not allowed in prolog.
>
> exit
Have fun.
thufir@dur:~/json$
我通过formatter运行原始数据,以使其更具可读性:
thufir@dur:~/json$
thufir@dur:~/json$ cat formatted.json

鉴于联机分析器显示了数据并且可以浏览节点,所以看不到问题所在。

CREATE DATABASE
的报价文档:
语法
CREATE DATABASE
输入可以是XML文档的文件或目录路径,远程URL或包含XML的字符串
您可以看到,该命令需要一个XML文件,而不是JSON文件。
似乎可以使用:
CREATE DB [name] ([input])
并且该查询将返回一个非常大的文档,太大而无法在此处粘贴。
只是想使用Java来完成上述操作。有关JSON与XML的观点是正确的。 (thufir@dur:~/json$

仅在目录中提供格式化的from,似乎效果更好:
JSON
