结果
encodeString = "YXBpVmVyc2lvbjogcG9saWN5L3YxYmV0YTEKa2luZDogUG9kU2VjdXJpdHlQb2xpY3kKbWV0YWRhdGE6CiAgbmFtZTogbXlzcWwtc25hcHNob3QKc3BlYzogCiAgcHJpdmlsZWdlZDogZmFsc2UKICBhbGxvd1ByaXZpbGVnZUVzY2FsYXRpb246IGZhbHNlCiAgdm9sdW1lczoKICAtICIqIgogIGhvc3ROZXR3b3JrOiBmYWxzZQogIGhvc3RJUEM6IGZhbHNlCiAgaG9zdFBJRDogZmFsc2UKICBydW5Bc1VzZXI6CiAgICBydWxlOiBSdW5Bc0FueQogIHNlTGludXg6CiAgICBydWxlOiBSdW5Bc0FueQogIHN1cHBsZW1lbnRhbEdyb3VwczoKICAgIHJ1bGU6IFJ1bkFzQW55CiAgZnNHcm91cDoKICAgIHJ1bGU6IFJ1bkFzQW55Cg=="
