cURL POST command line on WINDOWS RESTful service
提问by Lothre1
My problem:Using the command line tool to curl my localhost server while sending some data along with my POST request is not working.
我的问题：使用命令行工具来卷曲我的本地主机服务器，同时发送一些数据和我的 POST 请求不起作用。
What seems to be causing the error:Imagine something like this
似乎导致错误的原因：想象一下这样的事情
curl -i -X POST -H 'Content-Type: application/json' -d '{"data1": "data goes here", "data2": "data2 goes here"}' http:localhost/path/to/api
curl -i -X POST -H 'Content-Type: application/json' -d '{"data1": "data goes here", "data2": "data2 goes here"}' http:localhost/path/to/api
Result of the returning data
返回数据结果
curl: (6) Could not resolve host: application; No data record of requested type
curl: (6) Could not resolve host: data goes here,; No data record of requested type
curl: (6) Could not resolve host: data2; No data record of requested type
curl: (3) [globbing] unmatched close brace/bracket at pos 16
After some searching i figured out that problem couldn't be the sintax used for the request since it works on UNIX shells.
经过一番搜索，我发现问题不可能是用于请求的语法，因为它适用于 UNIX shell。
Are you possibly using Windows? That so looks like a completely broken shell that doesn't properly deal with single-quotes vs double-quotes. I just tried that command line and it worked fine on my linux box. http://curl.haxx.se/mail/archive-2011-03/0066.html
你可能使用 Windows 吗？这看起来像是一个完全损坏的外壳，无法正确处理单引号与双引号。我刚刚尝试了该命令行，它在我的 linux 机器上运行良好。 http://curl.haxx.se/mail/archive-2011-03/0066.html
I tried to work around with those " escaping it \" but it still didn't work
我试图解决那些“逃避它”的问题，但它仍然没有用

curl -i -X POST -H 'Content-Type: application/json' -d '{\"data1\": \"data goes here\", \"data2\": \"data2 goes here\"}' http: //localhost/path/to/api
curl -i -X POST -H 'Content-Type: application/json' -d '{\"data1\": \"data go here\", \"data2\": \"data2 go here\"}' http://localhost/path/to/api

curl -i -X POST -H 'Content-Type: application/json' -d '{\"data1\": \"data goes here\", \"data2\": \"data2 goes here\"}' http: //localhost/path/to/api
curl -i -X POST -H 'Content-Type: application/json' -d '{\"data1\": \"data go here\", \"data2\": \"data2 go here\"}' http://localhost/path/to/api
So i gave up. Windows seems to messing up with the JSON object sent on POST
所以我放弃了。Windows 似乎搞乱了 POST 上发送的 JSON 对象

I ran into the same issue on my win7 x64 laptop and was able to get it working using the curl release that is labeled Win64 - Generic w SSLby using the very similar command line format:
我在我的 win7 x64 笔记本电脑上遇到了同样的问题，并且能够通过使用非常相似的命令行格式使用标记为Win64 - Generic w SSL的 curl 版本使其工作：
C:\Projects\curl-7.23.1-win64-ssl-sspi>curl -H "Content-Type: application/json" -X POST http://localhost/someapi -d "{\"Name\":\"Test Value\"}"
Which only differs from your 2nd escape version by using double-quotes around the escaped ones and the header parameter value. Definitely prefer the linux shell syntax more.
这与您的第二个转义版本仅在转义和标头参数值周围使用双引号不同。绝对更喜欢 linux shell 语法。

Another Alternative for the command line that is easier than fighting with quotation marks is to put the json into a file, and use the @ prefix of curl parameters, e.g. with the following in json.txt:
命令行的另一种比使用引号更容易的替代方法是将 json 放入文件中，并使用 curl 参数的 @ 前缀，例如在 json.txt 中使用以下内容：
{ "syncheader" : {
"servertimesync" : "20131126121749",
"deviceid" : "testDevice"
}
}
then in my case I issue:
然后在我的情况下，我发出：
curl localhost:9000/sync -H "Content-type:application/json" -X POST -d @json.txt
Keeps the json more readable too.
也使 json 更具可读性。

Alternative solution: A More Userfriendly solution than command line:
替代解决方案：比命令行更用户友好的解决方案：
If you are looking for a user friendly way to send and request data using HTTP Methods other than simple GET's probably you are looking for a chrome extention just like this one http://goo.gl/rVW22fcalled AVANCED REST CLIENT
如果您正在寻找一种用户友好的方式来使用 HTTP 方法而不是简单的 GET 方法发送和请求数据，那么您可能正在寻找一种像http://goo.gl/rVW22f称为 AVANCED REST CLIENT的 chrome 扩展
For guys looking to stay with command-line i recommend cygwin:
对于希望使用命令行的人，我推荐 cygwin：
I ended up installing cygwin with CURL which allow us to Get that Linux feeling - on Windows!
Using Cygwin command line this issues have stopped and most important, the request syntax used on 1. worked fine.
我最终安装了带有 CURL 的 cygwin，这让我们能够在 Windows 上获得那种 Linux 的感觉！
使用 Cygwin 命令行此问题已停止，最重要的是，1. 上使用的请求语法工作正常。
Useful links:

Where i was downloading the curl for windows command line?

I hope it helps someone because i spent all morning on this.
我希望它可以帮助某人，因为我整个上午都在做这个。

At least for the Windows binary version I tested, (the Generic Win64 no-SSL binary, currently based on 7.33.0), you are subject to limitations in how the command line arguments are being parsed. The answer by xmas describes the correct syntax in that setting, which also works in a batch file. Using the example provided:
至少对于我测试的 Windows 二进制版本（通用 Win64 no-SSL 二进制文件，目前基于7.33.0），您会受到命令行参数解析方式的限制。xmas 的答案描述了该设置中的正确语法，这也适用于批处理文件。使用提供的示例：
curl -i -X POST -H "Content-Type: application/json" -d "{""data1"":""data goes here"",""data2"":""data2 goes here""}" http:localhost/path/to/api
A cleaner alternative to avoid having to deal with escaped characters, which is dependent upon whatever library is used to parse the command line, is to have your standard json format text in a separate file:
避免处理转义字符（依赖于用于解析命令行的任何库）的一种更简洁的替代方法是将标准 json 格式文本放在单独的文件中：
curl -i -X POST -H "Content-Type: application/json" -d "@body.json" http:localhost/path/to/api

- Try to use double quotes (") instead of single ones (').
- To preserve JSON format quotes, try doubling them ("").
To preserve quotes inside data, try to double-escape them like this (\\"").
curl ... -d "{""data1"": ""data1 goes here"", ""data2"": ""data2 goes here""}" curl ... -d "{""data"": ""data \""abc\"" goes here""}"
- 尝试使用双引号 (") 而不是单引号 (')。
- 要保留 JSON 格式的引号，请尝试将它们加倍 ("")。
要保留数据中的引号，请尝试像这样 (\\"") 对它们进行双重转义。
curl ... -d "{""data1"": ""data1 goes here"", ""data2"": ""data2 goes here""}" curl ... -d "{""data"": ""data \""abc\"" goes here""}"

One more alternative cross-platform solution on powershell 6.2.3:
powershell 6.2.3 上的另一种替代跨平台解决方案：
$headers = @{
'Authorization' = 'Token 12d119ad48f9b70ed53846f9e3d051dc31afab27'
}
$body = @"
{
"value":"3.92.0",
"product":"847"
}
"@
$params = @{
Uri = 'http://local.vcs:9999/api/v1/version/'
Headers = $headers
Method = 'POST'
Body = $body
ContentType = 'application/json'
}
Invoke-RestMethod @params
