记得12年的时候给大家发布过php调用接口的源码，这个是asp.net的，但原理基本上都是一样的，为了防止有些软件恶意获取手机验证码，这个例子加了图片验证码，也就是说要先输入图片中的验证码，才可以获取手机验证码，这样可以有效防止软件的恶意获取，当然如果恶意获取手机短信的软件可以识别你的验 证码，那这样做也是没有意义的，但防止恶意获取其实方法很多，这只是其中的一个例子，希望能起到对大家帮助的作用。调用接口的话，还是调用56短信网的，关于接口中返回的值，也可以具体参考56短信网。-Remember 12 years when the PHP call interface to the source, this is asp.net, but the principle is basically the same, in order to prevent some software malicious access to mobile verification code, which is to enter the picture in the verification code, you can get the phone verification code, which can effectively prevent the software　malicious access, of course, if you want to get a mobile phone text message software can identify your verification code, it is not meaningful, but it is only an example of the role of hope to play a role in. Call interface, or call 56 SMS network, the value of the return on the interface, you can also refer to the specific reference 56.
