如何在没有伪指令的情况下在MIPS中打印字符

Question

<span id='twilio_token' style='display: none;'><?php echo $token->toJWT()?></span>

当我执行此操作而不是显示y时它什么也没有显示，如果我var accessToken = document.getElementById('twilio_token').innerHTML; console.log(accessToken); // create an Endpoint and connect to Twilio endpoint = new Twilio.Endpoint(accessToken); endpoint.listen().then( endpointConnected, function (error) { log('Could not connect to Twilio: ' + error.message); } ); 并执行它它显示.globl main .globl store .data eq1: .asciiz "y=2*x+4" .text main: lui $t0,0x1000 ori $t0,$t0,0x0000 lui $t1,0x1000 ori $t1,$t1,0x0002 lui $t2,0x1000 ori $t2,$t2,0x0004 lui $t3,0x1000 ori $t3,$t3,0x0006 lui $t4,0x1000 ori $t4,$t4,0x0008 store: addi $v0,$0,11 lui $a0,0x1000 syscall add $0,$0,$0 ////////////////// ////////////////////////////////////

Answer 1

打印字符系统调用期望实际字符不是其地址。因此，您需要在lb $a0, ($a0)之前执行syscall。
