有没有一种方法可以传递文件内容进行卷曲？ [英] Is there a way to pass the content of a file to curl?
问题描述
我想从命令行执行一个具有多部分/混合边界的相当复杂的HTTP请求。
I would like to execute a fairly complex HTTP request with multipart/mixed boundaries from the command line.
POST /batch HTTP/1.1
Host: www.googleapis.com
Content-length: 592
Content-type: multipart/mixed; boundary=batch_0123456789
Authorization: Bearer authorization_token
--batch_0123456789
Content-Type: application/http
Content-ID: <item1:user@example.com>
Content-Transfer-Encoding: binary
POST /drive/v2/files/fileId/permissions
Content-Type: application/json
Content-Length: 71
{
"role": "reader",
"type": "user",
"value": "user@example.com"
}
--batch_0123456789
Content-Type: application/http
Content-ID: <item2:user@example.com>
Content-Transfer-Encoding: binary
POST /drive/v2/files/fileId/permissions
Content-Type: application/json
Content-Length: 71
{
"role": "reader",
"type": "user",
"value": "user@example.com"
}
--batch_0123456789--
理想情况下，我想将此请求放入文件中，然后简单地调用curl执行该HTTP请求。
Ideally I would like to put this request into a file and then simply call curl to execute that HTTP request.
curl myrequest.txt
是否有任何简单易行的方法？我知道有些客户端库有其惯用的方式来处理此问题，但我很想知道是否可以从命令行中执行此操作。
Is there any easy straightforward way of doing this? I understand that there are client libraries that have their idiomatic ways of handling this, but I am interested to find out if there is a way to do this from the command line.
推荐答案
您可以使用 -config 选项（请参见手册（了解更多详细信息））：
You can use the --config option (see the "CONFIG FILE" section of the manual for more details):
curl --config myrequest.txt
我认为没有一种干净的方法可以在配置文件中嵌入多行POST正文。您可以使用 \r\n 替换每个换行符（对于多部分请求，需要CRLF换行符）：
I don't think there's a clean way to embed a multiline POST body within the config file. You could replace each newline character with \r\n (CRLF newlines are required for multipart requests):
url = "http://www.googleapis.com/batch"
header = "Content-length: 592"
header = "Content-type: multipart/mixed; boundary=batch_0123456789"
header = "Authorization: Bearer authorization_token"
data-binary = "--batch_0123456789\r\nContent-Type: application/http\r\nContent-ID: <item1:user@example.com>\r\nContent-Transfer-Encoding: binary\r\n\r\n..."
但这不是很容易阅读。
或者，您可以放置POST正文在一个单独的文件中。例如：
Alternatively, you could put the POST body in a separate file. For example:
myrequest.txt
url = "http://www.googleapis.com/batch"
header = "Content-length: 592"
header = "Content-type: multipart/mixed; boundary=batch_0123456789"
header = "Authorization: Bearer authorization_token"
data-binary = "@myrequestbody.txt"
myrequestbody.txt
--batch_0123456789
Content-Type: application/http
Content-ID: <item1:user@example.com>
Content-Transfer-Encoding: binary
POST /drive/v2/files/fileId/permissions
Content-Type: application/json
Content-Length: 71
...
