如何使用Curl从终端/命令行发布JSON数据以测试Spring REST? [英] How do I POST JSON data with Curl from a terminal/commandline to Test Spring REST?

问题描述

我使用Ubuntu，并在其上安装 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，因为请求实体的格式不受请求的方法()所请求的资源支持.

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(我已经测试了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

您需要将内容类型设置为application/json.但是 -d 发送内容类型application/x-www-form-urlencoded，但不是在春天那边被接受了.

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是--header的缩写，-d是--data的缩写)

(-H is short for --header, -d for --data)

请注意，如果您使用-d，则-request POST是可选，因为-d标志表示POST请求.

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.请参阅评论主题.

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