java - Curl 在 JetBrains IDE (Windows) 中无法用于 POST

Question

我正在学习 Spring 指南教程:使用 Spring 构建 Rest 服务。

我已经按照文本操作并在教程中输入了代码。

我到了启动服务(在本地机器上)并使用 CURL 命令进行测试的部分。

GET 工作正常:

Curl -v localhost:8080/employees

返回预期列表

[{"id":1,"name":"Bilbo Baggins","role":"burglar"},{"id":2,"name":"Frodo Baggins","role":"thief"}]

但是，当我执行:

curl -X POST localhost:8080/employees -H 'Content-type:application/json' -d '{"name": "Samwise Gamgee", "role": "gardener"}'

我得到:

{"timestamp":"2018-11-08T20:55:49.844+0000","status":415,"error":"Unsupported Media Type","message":"Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported","path":"/employees"}

这是 Controller 代码

package com.mainsworth.payroll;

import java.util.List;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

 @RestController

 class EmployeeController {
     private final EmployeeRepository repository;
     EmployeeController(EmployeeRepository repository) {
         this.repository = repository;
    }

@GetMapping("/employees")
List<Employee>all() {
    return repository.findAll();
}

@PostMapping("/employees")
Employee newEmployee(@RequestBody Employee newEmployee) {
    return repository.save(newEmployee);
}

//Single item
@GetMapping("/employees/{id}")
Employee one(@PathVariable Long id) {
    return repository.findById(id)
            .orElseThrow(()-> new EmployeeNotFoundException(id));
}

@PutMapping("/employees/{id}")
Employee replaceEmployee(@RequestBody Employee newEmployee,
                         @PathVariable Long id ) {
    return repository.findById(id)
            .map(employee -> {
                employee.setName(newEmployee.getName());
                employee.setRole(newEmployee.getRole());
                return repository.save(employee);
            })
            .orElseGet(() -> {
                newEmployee.setId(id);
                return repository.save(newEmployee);
            });

}
@DeleteMapping("/employees/{id}")
void deleteEmployee(@PathVariable Long id) {
    repository.deleteById(id);
}

}

我听从了 Karol 和 Jesper 的建议。感谢两位的快速响应。我的新 curl 是:

curl -X POST  localhost:8080/employees -H 'Content-Type: application/json' -H 'Accept: application/json' -d '{"name": "Samwise Gamgee","role": "gardener"}'

我的新回复是:

{"timestamp":"2018-11-08T22:49:01.900+0000","status":415,"error":"Unsupported Media Type","message":"Content type 'application/x-www-form-urlencoded;charset=UTF-8' 
not supported","path":"/employees"}application
curl: (6) Could not resolve host: application

curl: (6) Could not resolve host: Samwise Gamgee,role

curl: (3) [globbing] unmatched close brace/bracket in column 9

Answer 1

在本教程中，它也在我身边发生:
https://spring.io/guides/tutorials/rest/

奇怪的是在 Linux 操作系统上它没有发生。我仔细检查了 Linux，一切都很好。

解决方案(示例):
反而:

curl -X POST localhost:8080/employees -H 'Content-type:application/json' -d '{"name": "Samwise Gamgee", "role": "gardener"}'

用:

curl -X POST localhost:8080/employees -H "Content-type:application/json" -d "{\"name\": \"Samwise Gamgee\", \"role\": \"gardener\"}"

总结:
将所有 ' 更改为 "并在正文中在每个 "之前添加\

我希望它有帮助!
