使用不了了？调任何接口都是http code 400

注：用xxx替换了部分信息。 我使用了自己的apikey和secretkey

我这里测试可用啊，是不是网络出现了问题？

我故意毁坏access_token（修改了几个字符）导致access_token失效，它又能正常的refresh回来。

这个感觉有点怪异。。还是不行？

[liyongxiong]

找到原因了，我替换了我自己的app，但是API服务列表里没开通PCI API。。。寒，打扰了。供日后碰到这个问题的同学参考。

http://developer.baidu.com/console#manage/apilist!appid=xxxx（xxx替换为自己的appid）

[liyongxiong]

顺便的，我是修改了源代码才发现问题的。 在__request_work函数里，失败的情况下只输出了r.status_code的调式信息，输出r.text那句默认被注释了，我打开了才发现提示信息是这样的：{"error_code":31024,"error_msg":"app id is empty","request_id":xxxx}

[houtianze]

哦，原来如此。 关掉那个r.text是因为下载大文件的时候如果打开-d开关，程序会卡死。

[liyongxiong]

可以考虑改为当http code不是200的时候才print

[houtianze]

__dump_exception()里有详细的print，为什么没出来呢？

[liyongxiong]

这种情况不是异常，__dump_exception()在异常处理里

[houtianze]

不只是异常才会调用的，只要返回码不是2xx，正常情况下都会调用的。
