英文:
Post request with content type application/x-www-form-urlencoded not working in Spring
问题
我正在使用OpenAPI生成器生成Spring REST API。以下是代码片段：
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
该生成器生成了一个Spring REST API方法（仅为一个有趣的方法）：
@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);
然后我想从集成测试中使用RestTemplate来调用它：
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);
然后我遇到了一个错误：
org.apache.tomcat.util.http.fileupload.impl.InvalidContentTypeException: the request doesn't contain a multipart/form-data or multipart/mixed stream, content type header is application/x-www-form-urlencoded
...（以下为错误堆栈信息）
我已经在服务器端进行了一些调试，看起来它期望一个多部分内容，但我不明白为什么会出现这种情况。
这是我尝试调用该服务的多个尝试之一。我已经检查了一些使用MultiValueMap的解决方案，还查看了这些问题，但是没有成功：
- 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 Boot版本：2.3.3-RELEASE（2.3.1-RELEASE也会失败）。
英文:
I'm using OpenAPI generator to generate Spring REST APIs. Here is a fragment:
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:

format: password
grant_type:
type: string
required:
- username
- password
- grant_type
OnlineAccount:
title: OnlineAccount
type: object
properties:
id:
type: string
It generates a Spring REST API method (only an interesting method):
@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);
Then I want to call it from my integration test using 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);
And I get an error:

I've debugged a little the server side and it looks like it expects a multipart content, but I don't understand why.
This is one of several attempts to call the service. I've checked some solutions using MultiValueMap, also these questions, but no success:
Http Post request with content type application/x-www-form-urlencoded not working in Spring
My Spring boo version: 2.3.3-RELEASE (fails also with 2.3.1-RELEASE)

你正在使用@RequestPart，该注解期望是MultipartFile类型的内容。如果没有特殊要求，请考虑更改为其他注解。
参考文档：链接
英文:
You are using @RequestPart which expects MultipartFile content type. Change @RequestPart if not specially required.

以下是翻译好的内容：
在 OpenAPI 生成器中存在一个错误（5 天前已打开）
https://github.com/OpenAPITools/openapi-generator/issues/7794
请注意，此问题中引用了一个提交，似乎修复了这个错误。
这是一个单行的 Mustache 模板 formParams.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 模板放在其中作为修复措施。
这可能对您有帮助。
英文:
there is a bug in open api generator (opened 5 days ago)
https://github.com/OpenAPITools/openapi-generator/issues/7794
Note that there is a commit referenced on this issue which seems to fix the bug.
It's a one-liner mustache template formParams.mustache.
If you rely on openapi-generator-maven-plugin, you could try using the templateDirectory config and put there the mustache template proposed as a fix.
Might do the trick for you.

刚刚遇到了这个问题。该行为在2020年的4.3.0版本中引入，于2022年得到修复。更多细节请参阅 https://stackoverflow.com/a/71954528/18619318
我发现升级到6.0.0-beta版本后，得到了我所期望的行为。请注意，如果您使用“spring”生成器，辅助类的命名已经发生了变化。
英文:
Just ran into this. The behaviour was introduced in 4.3.0 in 2020, and fixed in 2022. More details in https://stackoverflow.com/a/71954528/18619318
I found that upgrading to 6.0.0-beta gave the behavior I was looking for. Note that naming of helper classes has changed, if you use the "spring" generator.
