内容类型为application / x-www-form-urlencoded的发布请求在Spring中不起作用

标签： java spring spring-boot x-www-form-urlencoded

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

它会生成一个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);

然后我想使用RestTemplate从集成测试中调用它：

    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：

我已经在服务器端进行了一些调试，看起来它希望包含多部分内容，但是我不明白为什么。

这是几次调用该服务的尝试之一。我已经使用MultiValueMap检查了一些解决方案，也回答了这些问题，但没有成功：

Http Post request with content type application/x-www-form-urlencoded not working in Spring

Spring MVC - @RequestParam causing MissingServletRequestParameterException with x-www-form-urlencoded

我的Spring boo版本：2.3.3-RELEASE（也无法在2.3.1-RELEASE中使用）

答案 0 :(得分：0)

您正在使用@RequestPart，它需要MultipartFile内容类型。如果没有特别要求，请更改@RequestPart。

阅读default value

开放api生成器中存在错误（5天前已打开） https://github.com/OpenAPITools/openapi-generator/issues/7794

请注意，此问题上引用了一个提交，似乎可以解决该错误。 这是单线胡须模板formParams.mustache。

如果您依赖openapi-generator-maven-plugin，则可以尝试使用templateDirectory配置，并在此处放置作为修复建议的胡须模板。 可能会帮您解决这个问题。
