Question

我正在尝试从shell脚本执行curl命令。此命令可以从cli正常运行。但是，我需要在shell脚本中执行它。 curl命令应该根据查询删除solr上的记录。

curl -v  -o /dev/null  -w %{http_code}    -H Content-Type:text/xml -X POST   http://localhost:8983/solr/content/update?commit=true -d  <delete><query>playlist_id:["" TO *]</query></delete> 

Note: Unnecessary use of -X or --request, POST is already inferred.

Critical error happened during solr data delete: Verify the state manually
Quitting now

我需要检索http状态代码以验证状态。执行以下shell脚本代码。

curl_command_tmp="http://localhost:8983/solr/content/update?commit=true -d <delete><query>playlist_id:["" TO *]</query></delete>"
    curl_command_tmp="curl -v  -o /dev/null  -w %{http_code}    -H Content-Type:text/xml -X POST   $curl_command_tmp"
            echo "Curl delete command $curl_command_tmp"
           status=`$curl_command_tmp`
            echo $status
            echo "status: '$status'"
           if [ "$status" != "200" ]; then
                     echo "Critical error happened during solr data delete: Verify the state manually"
                     echo "Quitting now"
                     exit 0
           fi

我尝试了不同的curl选项（例如-G， - data-urlencode）。但他们不起作用。我想如果我可以传递完整的请求体而不会被截断，那么它将起作用。但它在solr http请求体中的“TO”之前被截断。我经历过各种论坛，但尚未解决。需要你的帮助来解决它

Answer 1

我在评论中尝试了这个建议，但它没有用。相反，我将数据(<delete><query>playlist_id:["" TO *]</query></delete>)放在文件中并像这样使用它：

-d @FILE_NAME

这没有任何缺陷。我的猜测是，如果数据具有curl无法在cli上处理的特殊字符，则使用文件。

注意： - 我没有在FILE中添加任何额外的引号或双引号。只需将实际需要发送的数据放入。

shell脚本中的curl请求不起作用
