如何使用cURL发布JSON数据？ [英] How do I POST JSON data with cURL?

问题描述

我使用Ubuntu，并在其上安装了 cURL 。我想用cURL测试我的Spring REST应用程序。我在Java端编写了POST代码。但是，我想用cURL对其进行测试。我正在尝试发布JSON数据。示例数据如下：

I use Ubuntu and installed cURL on it. I want to test my Spring REST application with cURL. I wrote my POST code at the Java side. However, I want to test it with cURL. I am trying to post a JSON data. Example data is like this:

{"value":"30","type":"Tip 3","targetModule":"Target 3","configurationGroup":null,"name":"Configuration Deneme 3","description":null,"identity":"Configuration Deneme 3","version":0,"systemId":3,"active":true}

我使用以下命令：

curl -i \
    -H "Accept: application/json" \
    -H "X-HTTP-Method-Override: PUT" \
    -X POST -d "value":"30","type":"Tip 3","targetModule":"Target 3","configurationGroup":null,"name":"Configuration Deneme 3","description":null,"identity":"Configuration Deneme 3","version":0,"systemId":3,"active":true \
    http://localhost:8080/xx/xxx/xxxx

它返回此错误：

HTTP/1.1 415 Unsupported Media Type
Server: Apache-Coyote/1.1
Content-Type: text/html;charset=utf-8
Content-Length: 1051
Date: Wed, 24 Aug 2011 08:50:17 GMT

错误描述是这样的：

服务器拒绝了此请求，因为请求实体位于

Tomcat日志：
POST / ui / webapp / conf / clear HTTP / 1.1 415 1051

Tomcat log: "POST /ui/webapp/conf/clear HTTP/1.1" 415 1051

cURL命令的正确格式是什么？

What is the right format of the cURL command?

这是我的Java端 PUT 代码（我已经测试过GET和DELETE并且它们可以工作）：

This is my Java side PUT code (I have tested GET and DELETE and they work):

@RequestMapping(method = RequestMethod.PUT)
public Configuration updateConfiguration(HttpServletResponse response, @RequestBody Configuration configuration) { //consider @Valid tag
    configuration.setName("PUT worked");
    //todo If error occurs response.sendError(HttpServletResponse.SC_NOT_FOUND);
    return configuration;
}

推荐答案

您需要设置内容-类型到application / json。但是 -d 发送Content-Type application / x-www-form-urlencoded ，在Spring端不接受。

You need to set your content-type to application/json. But -d sends the Content-Type application/x-www-form-urlencoded, which is not accepted on Spring's side.

查看卷曲手册页，我认为您可以使用 -H ：

Looking at the curl man page, I think you can use -H:

-H "Content-Type: application/json"

完整示例：

curl --header "Content-Type: application/json" \
  --request POST \
  --data '{"username":"xyz","password":"xyz"}' \
  http://localhost:3000/api/login

（ -H 很短对于-标题， -d 对于-data ）

请注意，如果您使用<$ c $，则-请求POST 是可选 c> -d ，如 -d 标志i

Note that -request POST is optional if you use -d, as the -d flag implies a POST request.

在Windows上，情况略有不同。参见评论主题。

On Windows, things are slightly different. See the comment thread.
