Any help or pointing me in the right direction would be appreciated. Thanks

推荐答案

从请求头可以很容易地看到你发送一些后的数据。但你并没有提供它。我给你一个HTTP请求如何转化为curl命令一个简单的例子。

From the request header it can be easily seen that you are sending some post data. But you didn't provide it. I give you a simple example on how a http request can be converted to curl command.

假设你有这样的要求，你要留言2表单变量 VAR1 和 VAR2 得到发表于 http://www.example.com/form.url 。该请求是这样的，

Suppose you have this request where you are posting 2 form variables var1 and var2 get POSTed to http://www.example.com/form.url. The request would look like this,

POST /form.url HTTP/1.1
Host: www.example.com
Accept:  text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Encoding: gzip, deflate
Content-Type: application/x-www-form-urlencoded; charset=UTF-8

var1=val1&var2=val2

当其转换为卷曲它像

curl -d 'var1=val1&var2=val2' \
--header 'Accept:  text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' \
--header 'Accept-Encoding gzip, deflate' \
--header 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8' \
'http://www.example.com/form.url'

请注意：

1. 这样就可以尽可能多添加你想要的标题。但它更好只添加这是必要的标头。因为卷曲将通过最头你（如主机，用户代理，内容类型，接受等）。

1. This way you can add as much as header you want. But its better you add only the headers which is necessary. Because curl will pass most headers for you (e.g. Host, User-Agent, Content-Type, Accept etc).

如果您要管理的cookie文件添加 cookie.txt 在当前目录和 -b cookie.txt -c饼干.TXT 命令开关卷曲。手段，

If you want to manage cookie add a file cookie.txt in the current directory and -b cookie.txt -c cookie.txt command switches to curl. Means,

-b/--cookie <name=string/file> Cookie string or file to read cookies from (H)
-c/--cookie-jar <file> Write cookies to this file after operation (H) 

-d 开关表示将在请求体传递数据串。

-d switch stands for the data string that will be passed in the request body.

-d/--data <data>   HTTP POST data (H)

现在我希望你可以建立你的命令。

Now I hope you can build your command.
