Question

来自bash / curl我正在使用一个接收POST的API，执行繁重的长任务并在成功时返回200。由于我们在WAF中面临一些超时，API已经改进以接受标题：

- 标题＆＃34;期望：102-处理＆＃34;

如果API收到该标头，它每20秒发送一次HTTP 102，直到进程结束并发送HTTP 200.这应该足以防止超时。

我需要做些什么才能处理这些HTTP 102？

我将该标题添加到我的curl命令中，但是一旦收到第一个102，curl命令就会完成。

我在想，也许curl中有一个参数要等到200或者错误。
我想到的另一个选择是在循环中查询状态，但我不知道如何指示curl监视该连接

这是我的bash脚本的测试版。

  else
    text102Header="NoExpect;" # send innofensive custom header

  if [[ "$pWaitForFooResponse" = true ]]; then

    Response=$(curl -k --write-out %{http_code} --header "$text102Header" --header "Content-Type:application/json" --silent --connect-timeout $pCURLConnectTimeout --output ./tmpResult.html -X POST --data "$pPayload" "$pFooUrl" 2>&1 | tee ./tmpResult.txt)
    echo "HTTP Response=$Response"
    echo "$(cat ./tmpResult.txt)"

    if [ "${Response:0:1}" -eq "1" ] || [ "${Response:0:1}" -eq "2" ]; then #if HTTP Response start by 1 or 2 (10x - 20x)...
      echo "Adapter sucessfully triggered."
      return 0

    echo "Adapter sucessfully (hopefully) triggered. NOT reading HTTP response until Foo code is upgraded to respond directly a HTTP 200 Successfully queued or similar."

手动运行并检查 curl -v作为标题发送的内容;我希望看到像

这样的东西

> POST /the/url HTTP/1.1
> Host: thehost.com:80
> User-Agent: curl/7.51.0
> Accept: */*
> Expect: 102-Processing
... some stuff skipped.

如果您没有发送Expect标头;然后卷曲实际上正在做正确的事情..

如何在bash中处理HTTP 102？
