You can return a RedirectResponse directly: How to get my app to return regular status 200 instead of redirecting it through 307. Thus, one of the first steps you can take to determine what might be causing these 307 Temporary Redirect response codes is to check the configuration files for your web server software for unintentional redirect instructions. If your application follows the application configuration section, injecting testing configuration is easy with dependency injection. Short: Minimize code duplication.

Also, it was being used by the include_router method, so I didn't wanna override it and have it cause weird behavior that would be difficult to track down. As seen in the chart above, for temporary redirects, you have three options: 302, 303, or 307. It happens because the exact path defined by you for your view is yourdomainname/hello/, so when you hit it without / at the end, it first attempts to get to that path but as it is not available it checks again after appending / and gives a redirect status code 307 and then when it finds the actual path it returns the status code that is defined in the function/view linked with that path, i.e . All modern browsers will automatically detect the 307 Temporary Redirect response code and process the redirection action to the new URI automatically. The IETF ratified HTTP Strict Transport Security (HSTS) in 2012 to force browsers to use secure connections when a site is running strictly on HTTPS. For example, even if the client request was sent using the POST HTTP method, many browsers would automatically send the second request to the temporary URI provided in the Location header, but would do so using the GET HTTP method. The status codes 303 and 307 have been added for servers that wish to make unambiguously clear which kind of reaction is expected of the client. Get well-versed with FastAPI features and best practices for testing, monitoring, and deployment to run high-quality and robust data science applicationsKey FeaturesCover the concepts of the FastAPI framework, including aspects relating to asynchronous programming, type hinting, and dependency injectionDevelop efficient RESTful APIs for data science with modern PythonBuild, test, and deploy .

Certain developers states this is an unexpected behavior and won't be supported in the future. So, the function will be executed once for each combination of arguments. For example, I have a router: router = HandleTrailingSlashRouter(prefix ="/v1/products"). By doing it this way, we can put it in a with block, and that way, ensure that it is closed after finishing. However, the solution given in that issue, i.e. Just like the author of #731, I don't want a 307 temporary redirect which is automatically sent by uvicorn when there's a missing trailing slash in the api call. In regards to the exported API schema only the non-trailing slash will be included. By default, FastAPI would automatically convert that return value to JSON using the jsonable_encoder. Thanks for contributing an answer to Stack Overflow! Convert the corresponding types (if needed). The HTTP 307 Internal Redirect response is a variant of the 307 Temporary Redirect status code. Robust: Get production-ready code. As indicated in the RFC, "since the redirection may be altered on occasion, the client should continue to use the Request-URI for future requests.".

In this case, the HTTP header Content-Type will be set to application/json. The method and the body of the original request are reused to perform the redirected request.

Capped collections work in a way similar to circular buffers: once a collection fills its allocated space, it makes room for new documents by overwriting the oldest documents in the collection.

Thus, while a 5xx category code indicates an actual problem has occurred on a server, a 3xx category code, such as 307 Temporary Redirect, is rarely indicative of an actual problem -- it merely occurs due to the server's behavior or configuration, but is not indicative of an error or bug on the server. This is a subtle but critical difference in functionality between the two, so it's important for web developers/admins to account for both scenarios. The image is configured through environmental variables. Certain developers states this is an unexpected behavior and . How to get my app to return regular status 200 instead of redirecting it through 307 This is the request output: abm | INFO: 172.18..1:46476 - "POST /hello HTTP/1.1" 307 Temporary Redirect abm | returns the apples data. get_settings is the dependency function that configures the Settings object.

The bug slipped through cause mainly I needed a way for all my paths to end without a trailing slash regardless of how it was given in the path decorator. Also, a malicious party can launch an MITM attack without changing the URL shown in the browsers address bar. A popular TV series even spoofed it in one of their episodes. Since there are so many potential codes, each of which represents a completely different status or event, it can be difficult to differentiate between many of them and determine the exact cause of such errors, including the 307 Temporary Redirect response code.
