Can'；在windows中使用curl发布json数据

我读过几篇关于这个主题的文章，但我不知道如何在Windows10（powershell）上用curl-POST发送json数据

我没有用\“或”“”试过。 json数据：

{
    "frames": [
        {
            "text": "HOME2",
            "icon": "i294",
            "index": 0
        },
        {
            "text": "? 65",
            "icon": null,
            "index": 1
        }
    ]
}

卷曲尝试的示例：

> curl -H "Accept: application/json" -H "X-Access-Token: xyz" -X POST "https://xyz" -d "{ """frames""": [{ """text""": """HOME2""", """icon""": """i294""", """index""": 0 }, { """text""": """? 65""", """icon""": null, """index""": 1 }]}"
{"error":{"code":null,"message":"Bad Request","trace":["request body must not be empty"]}}curl: (3) [globbing] bad range specification in column 2
curl: (6) Could not resolve host: text
curl: (6) Could not resolve host: HOME2,
curl: (6) Could not resolve host: icon
curl: (6) Could not resolve host: i294,
curl: (6) Could not resolve host: index
curl: (6) Could not resolve host: 0
curl: (3) [globbing] unmatched close brace/bracket in column 1
curl: (3) [globbing] unmatched brace in column 1
curl: (6) Could not resolve host: text
curl: (6) Could not resolve host: ? 65,
curl: (6) Could not resolve host: icon
curl: (6) Could not resolve host: null,
curl: (6) Could not resolve host: index
curl: (6) Could not resolve host: 1
curl: (3) [globbing] unmatched close brace/bracket in column 1

用\“

我做错了什么

首先缩小json，不要使用漂亮的json

试试这个：

curl -d 'curl -d '{"frames":[{"text":"HOME2","icon":"i294","index":0}, 
 {"text":"? 65","icon":null,"index":1}]}' -H 'Content-Type: application/json' 
 https://example.com/login

，因此，在进一步阅读并从mohsen的回答中，我将命令行定稿为：

curl -H "Accept: application/json" -H "X-Access-Token: xyz" -X POST "https://xyz" -d @exported.json

我将json添加到一个名为export.json的文件中，现在它更紧凑了，并且仍然可以工作

json数据本身不需要太多调整，请参见exported.json文件：

{"frames":[{"text":"HOME2","icon":"i294","index":"0"},{"text":"? 65","icon":"null","index":"1"}]}

看起来Windows命令行和PowerShell会处理curl和JSON post数据。在CMD、PowerShell和WSL中尝试了以下操作。WSL给出了我预期的结果，其他两个失败。（最初尝试将数据发布到Node Red，但他们的官方示例失败，这是我的WTF时刻）

试试这个（httpbin.org只是在本案例中回显您的数据）：

curl-xpost-d'{“name”：“Nick”，“a”：32}'-H“内容类型：application/json”https://httpbin.org/anything

从WSL调用时的响应：

{
  "args": {},
  "data": "{\"name\":\"Nick\",\"a\":32}",
  "files": {},
  "form": {},
  "headers": {
    "Accept": "*/*",
    "Content-Length": "22",
    "Content-Type": "application/json",
    "Host": "httpbin.org",
    "User-Agent": "curl/7.71.1"
  },
  "json": {
    "a": 32,
    "name": "Nick"
  },
  "method": "POST",
  "origin": "*********",
  "url": "https://httpbin.org/anything"
}

从CMD/PS调用时的响应：

{
  "args": {},
  "data": "'{name:Nick,a:32}'",
  "files": {},
  "form": {},
  "headers": {
    "Accept": "*/*",
    "Content-Length": "18",
    "Content-Type": "application/json",
    "Host": "httpbin.org",
    "User-Agent": "curl/7.55.1"
  },
  "json": null,
  "method": "POST",
  "origin": "****",
  "url": "https://httpbin.org/anything"
}

注意

Content Length

不同，从cmd或ps调用时，响应中的

json

属性为

null

但是这样做在WSL和cmd中都可以，但在PowerShell中不行：

curl-d“{\'name\：\'Nick\”，\“a\”：32}“-H”内容类型：application/jsonhttps://httpbin.org/anything

这在PowerShell中工作，但在另外两个

curl-d'{\'name\'：\'Nick\'，\'a\'：32}'-H“内容类型：application/json”中失败https://httpbin.org/anything

当然，powershell有它自己的规则，所以在其他程序中，你可以执行

-d@data.json

，但在powershell中，你必须输入

-d`@data.json

（在

@

符号前打勾）

这有帮助，但仅适用于cygwin windows。在windows powershell上，它仍然会引发错误。您的示例是的，但如果我使用我的json数据集，它仍然会在windows powershell中抱怨。我用最新发现更新了我的问题，以及现在有效的方法。不要更新问题，只需回答您的问题以改善社区即可

{
  "args": {},
  "data": "'{name:Nick,a:32}'",
  "files": {},
  "form": {},
  "headers": {
    "Accept": "*/*",
    "Content-Length": "18",
    "Content-Type": "application/json",
    "Host": "httpbin.org",
    "User-Agent": "curl/7.55.1"
  },
  "json": null,
  "method": "POST",
  "origin": "****",
  "url": "https://httpbin.org/anything"
}
