It seems that the property scene.render.layers['RenderLayer'] is no longer available in blender-2.8. I just want to set the use_pass_uv property of the current scene, then what should I do?

'scene.render.layers['RenderLayer'].use_pass_uv=True' works well in blender-2.7, but in blender-2.8, there was an error like this ''AttributeError: 'RenderSettings' object has no attribute 'layers

Render layers have been replaced by View Layers. Recommend do a search in the API docs or use the python console to figure out how to access the ViewLayers of the current scene:

 >>> C.scene.view_

>>> for vl in C.scene.view_layers: # Iterate through all view layers
...     print (vl.name) # print the name
View Layer
View Layer.001
View Layer.002

You can also access the current ViewLayer (in context) by using bpy.context.view_layer (or by using C convenience variable in the console C.view_layer):

>>> C.view_layer # View layer reference
bpy.data.scenes['Scene'].view_layers["View Layer"]

>>> C.view_layer.name # View layer name
'View Layer.001'

Another way is using get(<LAYERNAME>) on Scene.ViewLayers collection:

>>> C.scene.view_layers.get('View Layer')
bpy.data.scenes['Scene'].view_layers["View Layer"]

>>> my_vl = C.scene.view_layers.get('View Layer')
>>> my_vl.name
'View Layer'

Basic example on how to set attributes of the current view layer (in context):

import bpy

# Get the current view layer
vl = bpy.context.view_layer

# Set uv pass attribute
vl.use_pass_uv = True

# Set normal pass attribute
vl.use_pass_normal = True

# Enable diffuse light passes
vl.use_pass_diffuse_direct = True
vl.use_pass_diffuse_indirect = True
vl.use_pass_diffuse_color = True

Example on how to enable the 'UV' as well as the 'Normal' pass on all view layers in the scene:

import bpy

for vl in bpy.context.scene.view_layers:
    vl.use_pass_uv = True       # Enable UV pass
    vl.use_pass_normal = True   # Enable normal pass
