cURL脚本手动运行正常，PHP/Cron执行报错的解决

我编写了nn.sh脚本，内容如下：

#/bin/sh
cd /var/www/html
/usr/bin/curl 'https://web-api.wtnnip.com/app' \
  -H 'authority: web-api.wtnnip.com' \
  -H 'accept: */*' \
  -H 'accept-language: ro-RO,ro;q=0.9,en-US;q=0.8,en;q=0.7' \
  -H 'content-type: application/json' \
  -H 'origin: https://www.wtnnip.com' \
  -H 'referer: https://www.wtnnip.com/ro-RO/non-professional' \
  -H 'sec-ch-ua: "Google Chrome";v="105", "Not)A;Brand";v="8", "Chromium";v="105"' \
  -H 'sec-ch-ua-mobile: ?0' \
  -H 'sec-ch-ua-platform: "Linux"' \
  -H 'sec-fetch-dest: empty' \
  -H 'sec-fetch-mode: cors' \
  -H 'sec-fetch-site: same-site' \
  -H 'user-agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Safari/537.36' \
  --compressed

手动执行脚本或在终端直接运行cURL命令均正常，能获取JSON集合。但通过Cron执行该脚本，或PHP用exec/passthru调用时，返回如下错误：

{"errors" : [ {
    "message" : "Invalid JSON payload in GraphQLAuth POST request.",
    "errorType" : "MalformedHttpRequestException"
  } ]
}

PHP直接调用cURL也出现相同错误。

补充环境信息：

• Debian 11、PHP 7.4、cURL 7.74
• 默认Shell为bash，曾尝试将脚本首行改为#/bin/bash

解决方法 #

将脚本首行改为#!/bin/bash，此前遗漏了开头的感叹号。
