Question

我从Linux shell脚本通过CURL发送多部分表单POST。该请求在Postman中正常工作，但是从CURL开始，它失败了：

Internal Server Error

然后

HTTP error before end of send, stop sending

我甚至直接从Postman复制Curl for Linux Shell代码并粘贴到shell脚本中，因此它应该与Postman完全相同。

这是命令：

curl --request POST \
  --no-alpn \
  --url https://XXXXXXXXXXX/api/v1.0/XXXXX/XXXXXX/XXXXX \
  --header 'accept: text/plain' \
  --header 'cache-control: no-cache' \
  --header 'content-type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW' \
  --header 'sessionid: $session_id' \
  --form filename=XXXXXX.zip \
  --form XXXXXX=XXXXXX \
  --form file=@$file_path \
  --trace-ascii /dev/stdout || exit $?
}

这是来自--trace-ascii：

我应该补充说，正在从Docker容器运行CURL命令。

Answer 1

你的curl命令有问题：$session_id有单引号，所以永远不会评估变量。

“双引号”每个包含空格/元字符和每个扩展的文字："$var"，"$(command "$var")"，"${array[@]}"，"a & b"。使用'single quotes'代码或文字$'s: 'Costs $5 US'，ssh host 'echo "$HOSTNAME"'。见

Answer 2

在我的特定情况下，问题是我发送了用双引号括起来的会话ID，因此服务器无法解析为数字，抛出异常并拒绝了请求。不得不抓住服务器日志来搞清楚。

原因会话ID是双引号是因为在代码的早期，我使用以下方式设置会话ID：

someJson | jq '.sessionId'

如果这样做，jq将以双引号返回结果。要获取不带双引号的值，请使用：

someJson | jq -r '.sessionId'

CURL多部分表单post - 发送结束前的HTTP错误，停止发送
