在 curl 抛出错误中发布请求
[英]Post request in curl throwing error
问题描述
I execute this curl request from command line:
我从命令行执行这个 curl 请求：
curl -X POST https://www.googleapis.com/bigquery/v2/projects/projname/queries?key={AIzaSyB740elm45sh9AkpuaekZW8eJbRi_oDDAc} \
After this command, I have a list of parameters to be passed:在这个命令之后，我有一个要传递的参数列表：
{
"query": "SELECT * FROM [red-road-574:TestSridevi.Trucks] LIMIT 20",
"defaultDataset": {
"datasetId": "TestSridevi",
"projectId": "red-road-574"
}
}
Bur after executing the first command itself, I get the error: Bur 在执行第一个命令本身后，我收到错误消息：

<p><b>411.</b> <ins>That’s an error.</ins>
<p>POST requests require a <code>Content-length</code> header. <ins>That’s all we know.</ins>
Any advice on how to resolve this would be appreciated.任何有关如何解决此问题的建议将不胜感激。

This will probably work:这可能会起作用：
curl -X POST -d "" https://www.googleapis.com/bigquery/v2/projects/projname/queries?key={AIzaSyB740elm45sh9AkpuaekZW8eJbRi_oDDAc}
The error message said that POST requests needs their Content-length header field filled out, which you did not provide.错误消息说 POST 请求需要填写它们的Content-length标头字段，您没有提供。 The -d "" switch fills out that for you. -d ""开关为您填写。 You could also just send a GET request instead, for which you don't need to provide the switch.您也可以只发送一个GET请求，您不需要提供开关。

Here is a list of HTTP status codes:以下是 HTTP 状态代码列表：
https://en.wikipedia.org/wiki/List_of_HTTP_status_codes https://en.wikipedia.org/wiki/List_of_HTTP_status_codes
The server wants you to specify the length of the request's content.服务器希望您指定请求内容的长度。
If you add -d "" onto the request CURL will send a Content-Length: 0 header.如果将 -d "" 添加到请求 CURL 将发送 Content-Length: 0 标头。
