如何使用选项和查询转义 cmd？
这就是我在脚本中的用法。逃避有什么错？
"curl --fail $solrIndex/update?commit=true -H \"Content-Type: text/xml\" --data-binary '<delete><query>*:*</query></delete>'"
这是它的执行方式：
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">17</int></lst>
</response>
curl: (6) Couldn't resolve host 'text'
工作原理：
$ 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>
This is how I have it in the script. What's wrong escaping it?
"curl --fail $solrIndex/update?commit=true -H \"Content-Type: text/xml\" --data-binary '<delete><query>*:*</query></delete>'"
This is how it executes:
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'
What works:
$ 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>

将命令存储在数组中而不是单个字符串中
并执行它
Store the command in an array instead of a single string
And execute it with
你几乎不应该引用整个命令；引用论据：
You should almost never quote the whole command; quote the arguments:
