[英]Grails 3.3.9: Forward copies params
We're migrating from Grails 2.x to 3.x. 我们正在从Grails 2.x迁移到3.x。 I can observe some different behaviour when using the forward function:
使用转发功能时,我可以观察到一些不同的行为:
class FooController {
def index() {
forward controller: 'foo', action : 'bar', params: params
}
def bar() {
render(
view: "/foo/foo"
)
}
}
When calling http://localhost:8080/foo?test=1 and halting in the bar()
method I can see that params
looks like that: 当调用http:// localhost:8080 / foo?test = 1并停止在
bar()
方法中时,我可以看到params
看起来像这样:
params = {GrailsParameterMap@11597} size = 4
0 = {LinkedHashMap$Entry@11607} "test" ->
key = "test"
value = {String[2]@11612}
0 = "1"
1 = "1"
1 = {LinkedHashMap$Entry@11608} "controller" -> "foo"
2 = {LinkedHashMap$Entry@11609} "format" -> "null"
3 = {LinkedHashMap$Entry@11610} "action" -> "bar"
As you can see the value of test
is saved twice as a String[]
. 如您所见,
test
的值两次保存为String[]
。 This behaviour is different than it used to be in Grails 2.5.6. 此行为不同于Grails 2.5.6中的行为。 Is there any way to set a flag to the Grails
forward
function in order to not get the params passed to the redirect controller? 有没有办法为Grails
forward
功能设置一个标志,以便不将参数传递给重定向控制器?
I think you don't need to add the param
. 我认为您不需要添加
param
。 forward
automatically forwards your parameters. forward
自动转发您的参数。 It's optional. 它是可选的。 If you add it, it will duplicate the values.
如果添加它,它将复制这些值。 Try with only:
仅尝试:
forward controller: 'foo', action : 'bar'
