如何用选项和查询转义cmd

Question

这就是我在脚本中的方式。逃避它有什么错?

"curl --fail $solrIndex/update?commit=true -H "Content-Type: text/xml" --data-binary '<delete><query>*:*</query></delete>'"

它是这样执行的:

curl --fail http://localhost:8080/solr/update?commit=true -H "Content-Type: text/xml" --data-binary '<delete><query>*:*</query></delete>'
<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader"><int name="status">0</int><int name="QTime">17</int></lst>
</response>
curl: (6) Couldn't resolve host 'text'

哪些是有效的方式:

$ curl --fail http://localhost:8080/solr/update?commit=true -H "Content-Type: text/xml" --data-binary '<delete><query>*:*</query></delete>'
<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader"><int name="status">0</int><int name="QTime">51</int></lst>
</response>

Answer 1

将命令存储在数组中，而不是单个字符串

cmd=(curl --fail $solrIndex/update?commit=true -H "Content-Type: text/xml" --data-binary '<delete><query>*:*</query></delete>')

然后用 执行

"${cmd[@]}"

Answer 2

你几乎不应该引用整个命令;引用参数:

curl --fail "$solrIndex/update?commit=true" -H "Content-Type: text/xml" --data-binary '<delete><query>*:*</query></delete>'
