如何使用cURL发布JSON数据?
我使用Ubuntu并安装在上面。我想用cURL测试我的springrest应用程序。我在Java端编写了我的POST代码。但是,我想用cURL来测试它。我试图发布一个JSON数据。示例数据如下所示:如何使用cURL发布JSON数据?,json,rest,spring-mvc,curl,http-headers,Json,Rest,Spring Mvc,Curl,Http Headers,我使用Ubuntu并安装在上面。我想用cURL测试我的springrest应用程序。我在Java端编写了我的POST代码。但是,我想用cURL来测试它。我试图发布一个JSON数据。示例数据如下所示: {"value":"30","type":"Tip 3","targetModule":"Target 3","configurationGroup":null,"name":"Configuration Deneme 3","description":null,"identity":"Config
{"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}
echo 'my.awesome.json.function({"do" : "whatever"})' | curl -X POST "http://url" -T -
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
curl -v -H "Content-Type: application/json" -X POST --data @params.json -u your_username:your_password http://localhost:8000/env/add_server
它返回以下错误:
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
错误描述如下:
服务器拒绝了此请求,因为请求实体的格式不受请求方法()的请求资源的支持
Tomcat日志:
“POST/ui/webapp/conf/clear HTTP/1.1”415 1051
cURL命令的正确格式是什么
这是我的Java端PUT
code(我已经测试了GET和DELETE,它们可以正常工作):
您需要将内容类型设置为application/json。但是(或
--data
)发送内容类型application/x-www-form-urlencoded
,Spring不接受该类型
查看,我认为您可以使用(或--header
):
完整示例:
curl --header "Content-Type: application/json" \
--request POST \
--data '{"username":"xyz","password":"xyz"}' \
http://localhost:3000/api/login
(-H
是--标题的缩写,-d
是--数据的缩写)
请注意,如果使用-d
,则-request POST
是可选的,因为-d
标志表示POST请求
在Windows上,情况略有不同。查看注释线程。尝试将数据放入文件中,比如说body.json
,然后使用
curl -H "Content-Type: application/json" --data @body.json http://localhost:8080/ui/webapp/conf
我也遇到了同样的问题。我可以通过指定
-H "Content-Type: application/json; charset=UTF-8"
您可能会发现resty很有用:
它是一个包装器,简化了命令行REST请求。您可以将它指向API端点,并提供PUT和POST命令。(示例改编自主页)
$restyhttp://127.0.0.1:8080/data #将resty设置为指向端点
$GET/blogs.json#GEThttp://127.0.0.1:8080/data/blogs.json
#放置JSON
$PUT/blogs/2.json'{“id”:2,“title”:“updated post”,“body”:“This is new.”
#从文件发布JSON
$POST/blogs/5.json
此外,通常仍然需要添加内容类型标题。不过,您可以这样做一次,以设置每个站点每个方法添加配置文件的默认值:它对我有用,使用:
curl -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"id":100}' http://localhost/api/postJsonReader.do
它很高兴地映射到Spring控制器:
@RequestMapping(value = "/postJsonReader", method = RequestMethod.POST)
public @ResponseBody String processPostJsonData(@RequestBody IdOnly idOnly) throws Exception {
logger.debug("JsonReaderController hit! Reading JSON data!"+idOnly.getId());
return "JSON Received";
}
i仅
是一个简单的id属性。这对我来说效果很好,另外还使用了基本身份验证:
curl -v --proxy '' --basic -u Administrator:password -X POST -H "Content-Type: application/json"
--data-binary '{"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://httpbin.org/post
当然,在没有SSL和已检查证书的情况下,您永远不应该使用基本身份验证
今天我再次遇到这个问题,使用Cygwin的cURL 7.49.1 for Windows。。。当使用带有JSON参数的--data
或--data binary
时,cURL会感到困惑,并将JSON中的{}
解释为URL模板。添加一个-g
参数来关闭cURL globbing修复了这个问题
另请参见。我正在使用以下格式对web服务器进行测试
use -F 'json data'
让我们假设这种JSON dict格式:
{
'comment': {
'who':'some_one',
'desc' : 'get it'
}
}
完整示例
如果您正在针对RESTful接口测试大量JSON发送/响应,那么您可能希望查看Chrome插件(它允许您手动定义web服务测试)及其基于Node.js的命令行伙伴(它允许您针对Postman测试的“集合”进行自动化测试)。免费和开放 对于Windows,对-d
值使用单引号对我不起作用,但在更改为双引号后它确实起作用。我还需要在花括号内转义双引号
也就是说,以下各项不起作用:
curl -i -X POST -H "Content-Type: application/json" -d '{"key":"val"}' http://localhost:8080/appname/path
但以下措施奏效了:
curl -i -X POST -H "Content-Type: application/json" -d "{\"key\":\"val\"}" http://localhost:8080/appname/path
使用卷曲窗口,尝试以下操作:
curl -X POST -H "Content-Type:application/json" -d "{\"firstName\": \"blablabla\",\"lastName\": \"dummy\",\"id\": \"123456\"}" http-host/_ah/api/employeeendpoint/v1/employee
这对我很有效
curl -X POST --data @json_out.txt http://localhost:8080/
在哪里,
-X
表示http动词
--data
表示要发送的数据。例如,创建一个JSON文件params.JSON,并将此内容添加到其中:
[
{
"environment": "Devel",
"description": "Machine for test, please do not delete!"
}
]
然后运行以下命令:
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
curl -v -H "Content-Type: application/json" -X POST --data @params.json -u your_username:your_password http://localhost:8000/env/add_server
这对我很有用:
curl -H "Content-Type: application/json" -X POST -d @./my_json_body.txt http://192.168.1.1/json
您还可以将JSON内容放入文件中,并通过标准输入使用--upload file
选项将其传递给curl,如下所示:
{"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}
echo 'my.awesome.json.function({"do" : "whatever"})' | curl -X POST "http://url" -T -
您可以使用其直观的GUI来组装cURL
命令
安装并启动邮递员
键入URL、帖子正文、请求标题等。pp
单击code
从下拉列表中选择cURL
复制并粘贴cURL
命令
注意:下拉列表中有几个自动生成请求的选项,这就是为什么我认为我的帖子首先是必要的。是推荐的curl
的替代方案,因为你可以
$ http POST http://example.com/some/endpoint name=value name1=value1
默认情况下,它讲JSON,并将为您设置必要的头以及将数据编码为有效的JSON。还有:
Some-Header:value
用于标题,以及
name==value
用于查询字符串参数。如果您有一大块数据,也可以从文件中读取,并对其进行JSON编码:
field=@file.txt
您可以将所需格式的扩展名作为url的结尾传递。
比如.json
或
.xml
注意:您需要在pom中添加jackson和jaxb maven依赖项。使用-d选项添加负载
curl -X POST \
http://<host>:<port>/<path> \
-H 'Accept: application/json' \
-H 'Content-Type: application/json' \
-d '{
"foo": "bar",
"lorem": "ipsum"
}'
curl-X POST\
http://:\
-H'Accept:application/json'\
-H'内容类型:应用程序/json'\
-d'{
“foo”:“bar”,
“知识”:“ipsum”
}'
此外:
使用-X POST来使用POST方法
使用-H“Accept:application/json”添加Accept类型头
使用-H“Content-Type:application/json”添加内容类型标题我为此制作了一个工具。它可以发送请求并格式化curl代码段:
下面是一个例子:
示例输出:
curl -XGET -H "Accept: application/json" -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"
您可以使用postman转换为CURL
这对我在Windows10上的工作很有效
curl -d "{"""owner""":"""sasdasdasdasd"""}" -H "Content-Type: application/json" -X PUT http://localhost:8080/api/changeowner/CAR4
如果要包含动态数据,这里还有另一种方法
#!/bin/bash
version=$1
text=$2
branch=$(git rev-parse --abbrev-ref HEAD)
repo_full_name=$(git config --get remote.origin.url | sed 's/.*:\/\/github.com\///;s/.git$//')
token=$(git config --global github.token)
generate_post_data()
{
cat <<EOF
{
"tag_name": "$version",
"target_commitish": "$branch",
"name": "$version",
"body": "$text",
"draft": false,
"prerelease": false
}
EOF
}
echo "Create release $version for repo: $repo_full_name branch: $branch"
curl --data "$(generate_post_data)" "https://api.github.com/repos/$repo_full_name/releases?access_token=$token"
#/bin/bash
