409
今天一个同事的接口突然报409,大概百度了一下,不是很清楚,谷歌也没找到特别好的解释
因为是直接调用的gitlab,就直接看了下gitlab的api
The following table shows the possible return codes for API requests.
| Return values | Description |
|---|---|
200 OK |
The GET, PUT or DELETE request was successful, and the resource itself is returned as JSON. |
202 Accepted |
The GET, PUT or DELETE request was successful, and the resource is scheduled for processing. |
204 No Content |
The server has successfully fulfilled the request, and there is no additional content to send in the response payload body. |
201 Created |
The POST request was successful, and the resource is returned as JSON. |
304 Not Modified |
The resource hasn't been modified since the last request. |
400 Bad Request |
A required attribute of the API request is missing. For example, the title of an issue is not given. |
401 Unauthorized |
The user isn't authenticated. A valid user token is necessary. |
403 Forbidden |
The request isn't allowed. For example, the user isn't allowed to delete a project. |
404 Not Found |
A resource couldn't be accessed. For example, an ID for a resource couldn't be found. |
405 Method Not Allowed |
The request isn't supported. |
409 Conflict |
A conflicting resource already exists. For example, creating a project with a name that already exists. |
412 |
The request was denied. This can happen if the If-Unmodified-Since header is provided when trying to delete a resource, which was modified in between. |
422 Unprocessable |
The entity couldn't be processed. |
429 Too Many Requests |
The user exceeded the application rate limits. |
500 Server Error |
While handling the request, something went wrong on the server. |
gitlab解释的很清晰,就是说资源已经存在了,再次创建失败
那为什么接口没有将报错message展示出来,查了一下代码是因为直接屏蔽了409状态码,直接用postman访问接口会返回具体错误信息,错误提示信息示例:
示例1:
{
"message": "Email has already been taken"
}
示例2:
{
"message": "Username has already been taken"
}
找gitlab负责人查了下数据,确实是用户已经存在了,但是用户状态是blocked(禁用),问题解决

415
好巧不巧,今天又一个项目遇到了一个奇怪的错误码415,平时开发不常见,让我去帮忙排查
先简单了解了一下,服务A直接通过postman调用是可以的,但是就是别的服务调用服务A响应415,先百度,直接说是请求头不支持导致的
查看postman请求头,Content-Type是application/json;改下请求头(直接取消传递Content-Type,默认),响应415,具体响应内容如下
{
"timestamp": "2023-02-14T09:55:54.342+0000",
"status": 415,
"error": "Unsupported Media Type",
"message": "Content type 'application/octet-stream' not supported",
"path": "/zhanye-admin/iam/sync/SchemaService"
}改成text/plain,则响应还是415,具体响应
{
"timestamp": "2023-02-14T09:58:07.376+0000",
"status": 415,
"error": "Unsupported Media Type",
"message": "Content type 'text/plain;charset=UTF-8' not supported",
"path": "/zhanye-admin/iam/sync/SchemaService"
}基本能确定是调用方请求头的问题,但是调用方说自己调用没问题,调用服务A跟调用别的系统都一样,别的服务都正常,就是服务A一直报错,服务A的开发同学也很委屈,我postman调用正常...文章来源：https://www.toymoban.com/news/detail-465759.html
那就直接curl调用一下试试吧,直接在B服务所在的服务器调用A服务,正常,ok,这就确定了是B服务调用的问题,直接将调用请求和响应截图给B服务开发同学,让他排查问题,最终发现B服务的请求头中Content-Type不是application/json,而是text/plain文章来源地址https://www.toymoban.com/news/detail-465759.html
