获取JavaScript中两个模式之间出现的所有值

Question

我必须用下面的长字符串。如何提取介于“url=”和“，”之间的所有值，以便获得以下数组？

"load("@bazel_tools//tools/build_defs/repo:http.bzl","http_jar")definclude_java_deps():http_jar(name="com_google_inject_guice",sha256="b378ffc35e7f7125b3c5f3a461d4591ae1685e3c781392f0c854ed7b7581d6d2",url="https://repo1.maven.org/maven2/com/google/inject/guice/4.0/guice-4.0.jar",)http_jar(name="org_sonatype_sisu_inject_cglib",sha256="42e1dfb26becbf1a633f25b47e39fcc422b85e77e4c0468d9a44f885f5fa0be2",url="https://repo1.maven.org/maven2/org/sonatype/sisu/inject/cglib/2.2.1-v20090111/cglib-2.2.1-v20090111.jar",)http_jar(name="javax_inject_javax_inject",sha256="91c77044a50c481636c32d916fd89c9118a72195390452c81065080f957de7ff",url="https://repo1.maven.org/maven2/javax/inject/javax.inject/1/javax.inject-1.jar",)"

[
  https://repo1.maven.org/maven2/com/google/inject/guice/4.0/guice-4.0.jar,
  https://repo1.maven.org/maven2/org/sonatype/sisu/inject/cglib/2.2.1-v20090111/cglib-2.2.1-v20090111.jar, 
  https://repo1.maven.org/maven2/javax/inject/javax.inject/1/javax.inject-1.jar
]

我尝试了以下方法，但它只给我第一次出现，但我需要它们。谢谢！

var arr = contents.split('url=').pop().split(',')

for(i in arr) {
    console.log(arr[i]);
}

您可以通过使用正则表达式来解决这个问题

const regEx = /(?:url=")([^,]+)(?:",)/gm;

const string = 'load("@bazel_tools//tools/build_defs/repo:http.bzl","http_jar")definclude_java_deps():http_jar(name="com_google_inject_guice",sha256="b378ffc35e7f7125b3c5f3a461d4591ae1685e3c781392f0c854ed7b7581d6d2",url="https://repo1.maven.org/maven2/com/google/inject/guice/4.0/guice-4.0.jar",)http_jar(name="org_sonatype_sisu_inject_cglib",sha256="42e1dfb26becbf1a633f25b47e39fcc422b85e77e4c0468d9a44f885f5fa0be2",url="https://repo1.maven.org/maven2/org/sonatype/sisu/inject/cglib/2.2.1-v20090111/cglib-2.2.1-v20090111.jar",)http_jar(name="javax_inject_javax_inject",sha256="91c77044a50c481636c32d916fd89c9118a72195390452c81065080f957de7ff",url="https://repo1.maven.org/maven2/javax/inject/javax.inject/1/javax.inject-1.jar",)'

const matches = string.matchAll(regEx);

for (const match of matches) {
  console.log(match[1]);
}
