Ruby 漂亮的打印哈希(格式化hash)，以便用户可读

my_hash = {:timestamp=>"20220322175545", :sign=>"3a7a9ad8af0f6ac360d35c4fc55c0a07a6022a5534341aef9a0b1bfca6a66354", :randomstr=>"4g72c3n8DLm62s23bsNb1y94q508HeH3", :body=>"{\"msisdn\":\"1064854558804\",\"iccid\":\"898602B5092190195023\",\"imsi\":\"460040545512918\"}", :code=>"00000", :msg=>"成功", :transationid=>"202203101038112179022022032218003700000002"}

puts JSON.pretty_generate(my_hash)

输出：
