JAVA-处理针对Content-Type的HttpClient请求：application / json

Question

Hope everyone is doing great.

problem : I am getting the following response every time I make a call to api for login via POST request

[status] => 415
[error] => Unsupported Media Type
[message] => Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported

Here is my code for Yii2 application Side :

$url = ['auth/login'];
$data = ['email'=>$email, 'password'=>$password];

$response = \Yii::$app->apiclient->createRequest()
    ->setMethod('post')

    ->setUrl($url)

    ->addHeaders(['Accept-Charset' => 'UTF-8'])
    ->addHeaders(['Accept' => 'application/json'])
    ->addHeaders(['Content-Type' => 'application/json'])
    ->addHeaders(['Accept-Language' => \app\helpers\Helper::getUserLanguage()])

    ->setData($data)

    ->send();

return $response;

Here is what my apiclient setting is in web.conf file under components section

'apiclient' => [
            'class' => 'yii\httpclient\Client',
            'baseUrl' => 'http://myserverName:8000',
        ],

Here is my code for Spring (JAVA) API side :

@RequestMapping(value = "/auth/login", method = RequestMethod.POST)
public ResponseEntity<?> authenticateUser(@Valid @RequestBody LoginRequest loginRequest) {}

Target : I want to get user data from api on if login credentials (email & password) are correct. Or even a validation error message will do

Context : I am using Yii2 framework as my Application (front-end) and Spring (JAVA) as my back-end (API)

side-note : the fun fact is that I am not even trying for content type application/x-www-form-urlencode as you can see in my Yii2 code but still I am getting the response mentioned in the problem.

Another fun fact is that when I call out for the same API in postman, I dont get any error and my response is exactly as it should be.

Any help is appreciated.

Answer 1

Add this to your request:

->setFormat(\\yii\\httpclient\\Client::FORMAT_JSON)

Answer 2

Try this :

@RequestMapping(value = "/auth/login", method = RequestMethod.POST, consumes = "application/json")
public ResponseEntity<?> authenticateUser(@Valid @RequestBody LoginRequest loginRequest, BindingResult bindingResult) {}

This may help you..

Thanks :)

Answer 3

The issue was wit the request I was sending to api.

Here is what I needed to do

$response = \Yii::$app->apiclient->createRequest()
            ->setMethod('POST')
            ->setUrl($url)
            ->setData($data)
            ->setFormat(\yii\httpclient\Client::FORMAT_JSON)

            ->addHeaders(['accept-charset' => 'utf-8'])
            ->addHeaders(['accept' => 'application/json'])
            ->addHeaders(['content-type' => 'application/json'])
            ->addHeaders(['accept-language' => \app\helpers\Helper::getUserLanguage()])

            ->send();

I added following line and it worked

->setFormat(\yii\httpclient\Client::FORMAT_JSON)

Note :

I have no idea about how and why it worked but this might be because PHP is a loosely typed language and JAVA is opposite. Java would ask for all minor details to be sent in order to process a request.
