assert.match(string, regexp[, message])

• string <string>
• regexp <RegExp>
• message <string> | <Error>

期望 string 输入与正则表达式匹配。

此特性目前处于实验阶段，名称可能会更改，也可能会再次完全删除。

const assert = require('assert').strict;

assert.match('I will fail', /pass/);
// AssertionError [ERR_ASSERTION]: The input did not match the regular ...

assert.match(123, /pass/);
// AssertionError [ERR_ASSERTION]: The "string" argument must be of type string.

assert.match('I will pass', /pass/);
// OK

如果值不匹配，或者 string 参数的类型不是 string，则抛出 AssertionError，其 message 属性设置为等于 message 参数的值。 如果未定义 message 参数，则分配默认错误消息。 如果 message 参数是 Error 的实例，则将抛出错误而不是 AssertionError。

• string <string>
• regexp <RegExp>
• message <string> | <Error>

Expects the string input to match the regular expression.

This feature is currently experimental and the name might change or it might be completely removed again.

const assert = require('assert').strict;

assert.match('I will fail', /pass/);
// AssertionError [ERR_ASSERTION]: The input did not match the regular ...

assert.match(123, /pass/);
// AssertionError [ERR_ASSERTION]: The "string" argument must be of type string.

assert.match('I will pass', /pass/);
// OK

If the values do not match, or if the string argument is of another type than string, an AssertionError is thrown with a message property set equal to the value of the message parameter. If the message parameter is undefined, a default error message is assigned. If the message parameter is an instance of an Error then it will be thrown instead of the AssertionError.
