Question

所以我有2个地址，它们返回json对象链接a返回AAAA，链接b返回BBBB

链接b有点复杂....基本上，casper应当继续调用链接b，直到设置了正确的值，并且从链接b返回正确的数据为止。这就是为什么我在{{1}内调用链接b的原因。 }

无论如何，问题是当我调用链接waitFor并casper.log它的内容时，它仍然为我提供链接b的内容

这是我的代码

这是日志

    casper2.start('http://localhost/skywin/client/charg/link/a' , function(){

         casper2.log('----------------------------LINK A ------------------------------]]]]]]', 'debug');
         casper2.log(this.getPageContent() , 'debug');
    })
    .waitFor(function check(){

        casper2.log('----------------------------LINK B------------------------------->>>>>>>', 'debug');
         var xdata =  this.open('http://localhost/skywin/client/charg/link/b').getPageContent();
         casper2.log(  (xdata) , 'warning');

        try {
            var rdata = JSON.parse(xdata) ;
        } catch (e) {
            return false;
        }
        return rdata.stat == 'BBBBBBB' ? true : false ;
    })
    .run(function(){
        this.echo("DONE 2");
    });

您可以看到我有

[info] [phantom] Step anonymous 2/3 http://localhost/skywin/client/charg/link/a (HTTP 200)
[debug] [phantom] ----------------------------LINK A ------------------------------]]]]]]
[debug] [phantom] {"stat":"AAAAAAA"}

它只是不断返回链接[debug] [phantom] ----------------------------LINK B------------------------------->>>>>>> [warning] [phantom] {"stat":"AAAAAAA"} [debug] [phantom] ----------------------------LINK B------------------------------->>>>>>> [warning] [phantom] <html><head></head><body style=""><pre style="word-wrap: break-word; white-space: pre-wrap;">{"stat":"AAAAAAA"}</pre></body></html> [warning] [phantom] Loading resource failed with status=fail: http://localhost/skywin/client/charg/link/b的内容我缺少什么吗？

btw我在浏览器中尝试了链接b，它返回了正确的值

在waitFor中调用链接返回前一个链接的内容
