业务场景:
需要传递给比较长的字符串, 写入到系统参数中, 在服务器中再取出内容.
测试脚本有几个问题:
1. 建议增加 inp_set_max_len, 可以调整到2000或4000, ntext不限制长度, 可能会需要传递多点数据
2. pub_para_set_save, 当保存的参数值过长时, 会导致客户端直接崩溃
3. pub_para_get, 这个函数会自动截断了取出的参数值, 在数据库中很长, 但是取出来就只有一部分
脚本如下:
int test()
{
return 1;
};
int main()
{
dbg_clear();
inp_clear();
inp_def_memo('batch_no', '批次');
inp_set_max_len('batch_no', 1000);
inp_para_set_title('批次明细');
if (inp_para() == 1) {
string batch_no;
batch_no = inp_get_val('batch_no');
dbg('batch_no: ' + batch_no);
// 修改参数
// pub_para_set_save('ks_batch_no', batch_no); // ------ batch_no 过长, 会导致客户端崩溃
string sql;
sql = "delete from app_para where para_id='ks_batch_no'";
db_run(sql);
sql = "insert into app_para (para_id, para_value) values ('ks_batch_no', '" + batch_no + "')";
db_run(sql);
msg('finish');
}
dbg_clear();
string batch_no;
batch_no = pub_para_get('ks_batch_no'); // ------ 这个也会截断参数值,
dbg(batch_no);
return 1;
};
传递内容, 测试数据, 更长就不行了. 因为参数最大长度目前只支持1000, :
