背景
- 近期在做 excel文件数据导出时,遇到如下报错:
iconv(): Detected an illegal character in input string
- 场景:计划任务后台,分步导出 大数据 excel文件
- 发现在加载文件时,会有报错
报错信息 如下:
{ "name": "PHP Notice", "message": "iconv(): Detected an illegal character in input string", "code": 8, "type": "yii\\base\\ErrorException", "file": "/usr/share/nginx/html/ycsh_automat/Classes/PHPExcel/Shared/String.php", "line": 490, "stack-trace": [ "#0 [internal function]: yii\\base\\ErrorHandler->handleError(8, 'iconv(): Detect...', '/usr/share/ngin...', 493, Array)", "#1 /usr/share/nginx/html/ycsh_automat/Classes/PHPExcel/Shared/String.php(490): iconv('CP1252', 'UTF-8', '\\xE8\\xAE\\xA2\\xE5\\x8D\\x95\\xE5\\x88\\x97\\xE8\\xA1\\xA8\\x00\\x00\\x00...')", "#2 /usr/share/nginx/html/ycsh_automat/Classes/PHPExcel/Reader/Excel5.php(1362): PHPExcel_Shared_String::ConvertEncoding('\\xE8\\xAE\\xA2\\xE5\\x8D\\x95\\xE5\\x88\\x97\\xE8\\xA1\\xA8\\x00\\x00\\x00...', 'UTF-8', 'CP1252')", "#3 /usr/share/nginx/html/ycsh_automat/Classes/PHPExcel/Reader/Excel5.php(633): PHPExcel_Reader_Excel5->readSummaryInformation()", "#4 /usr/share/nginx/html/ycsh_automat/Classes/PHPExcel/IOFactory.php(192): PHPExcel_Reader_Excel5->load('/usr/share/ngin...')", "#5 /usr/share/nginx/html/ycsh_automat/common/services/ExcelMzService.php(154): PHPExcel_IOFactory::load('/usr/share/ngin...')", "#6 /usr/share/nginx/html/ycsh_automat/common/models/ExportTask.php(306): common\\services\\ExcelMzService->cronCreateExportFile(Array, Array, '/usr/share/ngin...', Array, '\\xE8\\xAE\\xA2\\xE5\\x8D\\x95\\xE5\\x88\\x97\\xE8\\xA1\\xA8')", "#7 /usr/share/nginx/html/ycsh_automat/api/controllers/CronController.php(54): common\\models\\ExportTask::execExportTask(Object(common\\models\\ExportTask), 1, '{\"search_params...')", "#8 [internal function]: api\\controllers\\CronController->actionRunExportTask()", ... }
问题分析
- 根据详细报错信息,可以知道,是执行 PHPExcel_IOFactory::load() 方法时,因为文件名编码问题造成程序中断
- 业务场景中,即在分步追加 excel文件数据,加载文件名时,识别转码有误
- 继而定位到 Classes\PHPExcel\Shared\String.php 的 ConvertEncoding() 方法的的第一个条件判断不满足
解决方案
修改文件 Classes\PHPExcel\Shared\String.php
的 ConvertEncoding()
方法的的第一个条件判断,如下
附录
- 网上的经验,基本为 php iconv() : Detected an illegal character in input string, 测试发现都无法解决我的问题
- 重点提示:当前报错,在
windows
环境中,不会报错,只有上传到Linux
服务器,才会有报错!
