的确比较奇怪
浏览器f12抓包看下,post请求的body有没有 firstname=xxx&lastname=xxx
给你的form加上enctype=application/x-www-form-urlencoded看看
把"firstname"删除重新打一次,以免中间有什么特殊字符。

Centos7,su root 如下:su: cannot open session: Error in service module
大神快来!!! 使用su 命名切换root用户 su root 提示输入密码,我已输入密码并且保证密码是正确的然后回车 提示错误: su: cannot open session: Error in service module
su - root返回 could not open session. 这是什么情况?
今天在做加固的时候,按照建议做了如下加固: 编辑文件(vi /etc/pam.d/su) 1.在文件内添加如下内容: auth sufficient pam_rootok.so auth required pam_wheel.so use_uid #只有wheel组中的用户可以使用su命令成为root用户.可根据实际情况将用户添加到wheel组,以使它可以使用su命令成为root用户. 添加方法: #usermod -G wheel username 同时我添加了一个用户到wheel分组, 但是此用户su - root时候,返回could not open session,请问有什么解决方案么?
Su-domino-ku 程序怎么写
Problem Description As if there were not already enough sudoku-like puzzles, the July 2009 issue of Games Magazine describes the following variant that combines facets of both sudoku and dominos. The puzzle is a form of a standard sudoku, in which there is a nine-by-nine grid that must be filled in using only digits 1 through 9. In a successful solution: Each row must contain each of the digits 1 through 9. Each column must contain each of the digits 1 through 9. Each of the indicated three-by-three squares must contain each of the digits 1 through 9. For a su-domino-ku, nine arbitrary cells are initialized with the numbers 1 to 9. This leaves 72 remaining cells. Those must be filled by making use of the following set of 36 domino tiles. The tile set includes one domino for each possible pair of unique numbers from 1 to 9 (e.g., 1+2, 1+3, 1+4, 1+5, 1+6, 1+7, 1+8, 1+9, 2+3, 2+4, 2+5, ...). Note well that there are not separate 1+2 and 2+1 tiles in the set; the single such domino can be rotated to provide either orientation. Also, note that dominos may cross the boundary of the three-by-three squares (as does the 2+9 domino in our coming example). To help you out, we will begin each puzzle by identifying the location of some of the dominos. For example, Figure 1 shows a sample puzzle in its initial state. Figure 2 shows the unique way to complete that puzzle. Input Each puzzle description begins with a line containing an integer N, for 10 ≤ N ≤ 35, representing the number of dominos that are initially placed in the starting configuration. Following that are N lines, each describing a single domino as U LU V LV. Value U is one of the numbers on the domino, and LU is a two-character string representing the location of value U on the board based on the grid system diagrammed in Figure 1. The variables V and LV representing the respective value and location of the other half of the domino. For example, our first sample input beings with a domino described as 6 B2 1 B3. This corresponds to the domino with values 6+1 being placed on the board such that value 6 is in row B, column 2 and value 1 in row B, column 3. The two locations for a given domino will always be neighboring. After the specification of the N dominos will be a final line that describes the initial locations of the isolated numbers, ordered from 1 to 9, using the same row-column conventions for describing locations on the board. All initial numbers and dominos will be at unique locations. The input file ends with a line containing 0. Output For each puzzle, output an initial line identifying the puzzle number, as shown below. Following that, output the 9x9 sudoku board that can be formed with the set of dominos. There will be a unique solution for each puzzle. Sample Input 10 6 B2 1 B3 2 C4 9 C3 6 D3 8 E3 7 E1 4 F1 8 B7 4 B8 3 F5 2 F6 7 F7 6 F8 5 G4 9 G5 7 I8 8 I9 7 C9 2 B9 C5 A3 D9 I4 A9 E5 A2 C6 I1 11 5 I9 2 H9 6 A5 7 A6 4 B8 6 C8 3 B5 8 B4 3 C3 2 D3 9 D2 8 E2 3 G2 5 H2 1 A2 8 A1 1 H8 3 I8 8 I3 7 I4 4 I6 9 I7 I5 E6 D1 F2 B3 G9 H7 C9 E5 0 Sample Output Puzzle 1 872643195 361975842 549218637 126754983 738169254 495832761 284597316 657381429 913426578 Puzzle 2 814267593 965831247 273945168 392176854 586492371 741358629 137529486 459683712 628714935

Each of the indicated three-by-three squares must contain each of the digits 1 through 9. For a su-domino-ku, nine arbitrary cells are initialized with the numbers 1 to 9. This leaves 72 remaining cells. Those must be filled by making use of the following set of 36 domino tiles. The tile set includes one domino for each possible pair of unique numbers from 1 to 9 (e.g., 1+2, 1+3, 1+4, 1+5, 1+6, 1+7, 1+8, 1+9, 2+3, 2+4, 2+5, ...). Note well that there are not separate 1+2 and 2+1 tiles in the set; the single such domino can be rotated to provide either orientation. Also, note that dominos may cross the boundary of the three-by-three squares (as does the 2+9 domino in our coming example). To help you out, we will begin each puzzle by identifying the location of some of the dominos. For example, Figure 1 shows a sample puzzle in its initial state. Figure 2 shows the unique way to complete that puzzle. Input Each puzzle description begins with a line containing an integer N, for 10 ≤ N ≤ 35, representing the number of dominos that are initially placed in the starting configuration. Following that are N lines, each describing a single domino as U LU V LV. Value U is one of the numbers on the domino, and LU is a two-character string representing the location of value U on the board based on the grid system diagrammed in Figure 1. The variables V and LV representing the respective value and location of the other half of the domino. For example, our first sample input beings with a domino described as 6 B2 1 B3. This corresponds to the domino with values 6+1 being placed on the board such that value 6 is in row B, column 2 and value 1 in row B, column 3. The two locations for a given domino will always be neighboring. After the specification of the N dominos will be a final line that describes the initial locations of the isolated numbers, ordered from 1 to 9, using the same row-column conventions for describing locations on the board. All initial numbers and dominos will be at unique locations. The input file ends with a line containing 0. Output For each puzzle, output an initial line identifying the puzzle number, as shown below. Following that, output the 9x9 sudoku board that can be formed with the set of dominos. There will be a unique solution for each puzzle.

Su-domino-ku 是怎么来写的
Problem Description As if there were not already enough sudoku-like puzzles, the July 2009 issue of Games Magazine describes the following variant that combines facets of both sudoku and dominos. The puzzle is a form of a standard sudoku, in which there is a nine-by-nine grid that must be filled in using only digits 1 through 9. In a successful solution: Each row must contain each of the digits 1 through 9. Each column must contain each of the digits 1 through 9. Each of the indicated three-by-three squares must contain each of the digits 1 through 9. For a su-domino-ku, nine arbitrary cells are initialized with the numbers 1 to 9. This leaves 72 remaining cells. Those must be filled by making use of the following set of 36 domino tiles. The tile set includes one domino for each possible pair of unique numbers from 1 to 9 (e.g., 1+2, 1+3, 1+4, 1+5, 1+6, 1+7, 1+8, 1+9, 2+3, 2+4, 2+5, ...). Note well that there are not separate 1+2 and 2+1 tiles in the set; the single such domino can be rotated to provide either orientation. Also, note that dominos may cross the boundary of the three-by-three squares (as does the 2+9 domino in our coming example). To help you out, we will begin each puzzle by identifying the location of some of the dominos. For example, Figure 1 shows a sample puzzle in its initial state. Figure 2 shows the unique way to complete that puzzle.
