我正在使用 OpenAPI 生成器来生成 Spring REST API。这是一个片段:

openapi: 3.0.2

info:
  version: 1.0.0
  title: Auth

paths:
  '/auth/v1/token':
    post:
      operationId: getAuthToken
      requestBody:
        content:
          "application/x-www-form-urlencoded":
            schema:
              $ref: '#/components/schemas/LoginRequest'
      responses:
        '200':
          description: 'Success'
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/OnlineAccount'

components:

  schemas:
    LoginRequest:
      type: object
      properties:
        username:
          type: string
        password:
          type: string
          format: password
        grant_type:
          type: string
      required:
        - username
        - password
        - grant_type

    OnlineAccount:
      title: OnlineAccount
      type: object
      properties:
        id:
          type: string

它生成一个 Spring REST API 方法(只是一个有趣的方法):

    @ApiOperation(value = "", nickname = "getAuthToken", notes = "", response = OnlineAccount.class, tags={  })
    @ApiResponses(value = { 
        @ApiResponse(code = 200, message = "Success", response = OnlineAccount.class) })
    @RequestMapping(value = "/auth/v1/token",
        produces = { "application/json" }, 
        consumes = { "application/x-www-form-urlencoded" },
        method = RequestMethod.POST)
    ResponseEntity<OnlineAccount> getAuthToken(@ApiParam(value = "", required=true) @RequestPart(value="username", required=true)  String username,@ApiParam(value = "", required=true) @RequestPart(value="password", required=true)  String password,@ApiParam(value = "", required=true) @RequestPart(value="grant_type", required=true)  String grantType);

然后我想从我的集成测试中调用它RestTemplate

    RequestEntity<String> requestEntity =
        RequestEntity.post(
                new URL("http://localhost:" + applicationPort + "/auth/v1/token").toURI())
            .contentType(MediaType.APPLICATION_FORM_URLENCODED)
            .body("username%3Dtest%40test-email.com%26password%3Dpassword");

    ResponseEntity<OnlineAccount> loginResponse =
        restTemplate.exchange(requestEntity, OnlineAccount.class);

我得到一个错误:

我已经调试了一点服务器端,看起来它需要一个多部分内容,但我不明白为什么。

这是调用该服务的几次尝试之一。我已经检查了一些解决方案MultiValueMap,还有这些问题,但没有成功:

内容类型为 application/x-www-form-urlencoded 的 Http Post 请求在 Spring 中不起作用

Spring MVC - @RequestParam 使用 x-www-form-urlencoded 导致 MissingServletRequestParameterException

我的 Spring boo 版本:2.3.3-RELEASE(2.3.1-RELEASE 也失败)

您正在使用@RequestPartwhich 期望MultipartFile内容类型。@RequestPart如果不是特别需要,请更改。

开放 api 生成器中有一个错误(5 天前开放) https://github.com/OpenAPITools/openapi-generator/issues/7794

请注意,在此问题上引用了一个提交,似乎修复了该错误。这是一个单行小胡子模板表单Params.mustache。

如果您依赖于 openapi-generator-maven-plugin,您可以尝试使用 templateDirectory 配置并将建议的 mustache 模板放在那里作为修复。可能会为您解决问题。
