使用curl POST多部分/表单数据的正确方法是什么？ [英] What is the right way to POST multipart/form-data using curl?

问题描述

我使用这个语法来发布一个文件以及一些参数：

$ $ $ $ $ codeurl -v -include --formkey1 = value1--form upload = localfilename URL

该文件大小约为500K。首先，我看到发送端的内容长度为254。稍后，服务器响应的内容长度为0.
我在哪里出错？

以下是命令的完整跟踪。

解决方案

  curl -v -F key1 = value1 -F upload = @ localfilename URL 
  

I used this syntax to post a file along with some parameters:

curl -v -include --form "key1=value1" --form upload=localfilename URL

The file is around 500K in size. First of all, I see content length to be 254 on the transmit side. Later the server response's content length is 0. Where am I going wrong?

Here is the complete trace of the command.

* Couldn't find host xxx.xxx.xxx.xxx in the _netrc file; using defaults

The following syntax fixes it for you:

curl -v -F key1=value1 -F upload=@localfilename URL
