问题描述
这是我试图循环的字符串,所以我尝试将其转换为 JSON。
{to_address_mobile: [The to address mobile field is required.],to_address_area_number_id: [The to address area number id field is required.]}
这是我尝试这样做的方法:
for (var validationError in json.decode('[${resp['data']}]')){
print(validationError);
}
每次都出现这个错误:
E/Flutter (22342): [ERROR:Flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: FormatException: Unexpected character (at character 3)
E/Flutter (22342): [{to_address_mobile: [The to address mobile field is required.],to_address...
解决方法
我写了一个正则表达式模式来从你的字符串中提取信息。如果它不是最佳选择,我很抱歉,但我从未真正使用过正则表达式:
from moviepy.editor import VideoFileClip
import moviepy.video.fx.all as vfx
clip = VideoFileClip(file_name)
resized_clip = clip .crop(clip,x1=0,y1=0,x2=1920,y2=1080)
单个匹配项是键值对,键位于命名组“key”中,值位于命名组“value”中。
