我现在有两个脚本，login.py和zaixian.py,两个脚本有依赖关系，现在需要你根据zaixian.py的脚本逻辑重新编写一个业务脚本yewu.py，处理接口请求,脚本输出内容把apimessage字段改成apiresponse，字段apiresponse用于存储接口的响应数据

本文介绍了解决在使用YIIcomposer安装Composerassetplugin插件过程中遇到的“Failedtodecoderesponse:zlib_decode():dataerror”错误的方法。通过指定插件的确切版本号而非使用范围指示符“^”，可以有效避免此问题。此外，文章还推荐了更新composer自身以确保最佳兼容性和性能。
解决方法：指定插件的版本将“^” 去掉
#composer global require "fxp/composer-asset-plugin:1.3.1
更新composer(#composer self-update）
