格式错误的 HTTP 请求 Laravel

Question

I am building a Laravel back-end API. The API has been implemented and I have tested all the necessary methods and routes. I am now busy creating some test-requests using Postman however I keep getting a 'Malformed HTTP Request' Error in Laravel.

The server side verification is done using Laravel Passport, below is the generated HTTP code from Postman

POST /api/my_data_url HTTP/1.1
Host: 127.0.0.1:8000
Accept: application/json
Authorization: Bearer oauth_key_goes_here
Content-Type: application/json

{
    "value_1": 123,
    "value_2": 123,
    "value_3": 123
}

I have had a look at the JSON:API standard however it is not necessary for the purposes of this app, it would be overkill as I am not creating a public API. This is my own app I will be using. On the controller side I merely want it to echo so it looks like this currently:

/**
* Store a newly created resource in storage.
*
* @param  \Illuminate\Http\Request  $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
  {
     return response()->json($request->json()->all(), 200);
  }

My end goal is to merely pass some sensor data to a Laravel API and use the appropriate controller method to verify and save it to a database. What am I missing, it feels like I am making a stupid mistake?

PS I know that there is another question with a very similar problem however it doesn't appear as if that question has a solution that will help me.

Answer 1

I thought my original answer was detailed enough as it is merely a configuration error. I will attempt a second answer that is more detailed here. Please note I am using the Linux-based desktop application, I cannot comment on other versions as I do not use them. My Laravel application was also built using Laravel 6.

My error was caused by incorrect request authorization settings. The steps below allowed me to correct the issue.

After you have opened the Postman application do the following:

1. Create a request in Postman by clicking on the Create a request label on the right-hand side of the start page of the desktop application
2. You will now be in the request creation tab. Within this, there are multiple tabs to allow you to configure parts of your request. eg Params , Authorization etc.
3. Navigate to the Authorization tab and change the Type dropdown to match the authorization schema your Laravel application uses.

These were the steps I took to fix the issue.

Answer 2

I eventually figured out what it was months later. My Postman configuration was incorrect. In the Postman settings I had configured the incorrect HTTP authentication scheme, so all my requests were "Malformed" because they contained a different security mechanism than that which Laravel knew. Once I corrected this and changed it from what it was to OAuth2 with a bearer token, my requests came through beautifully!
