Code Snippet of api call:

private fun getUserList() {
        var retrofit = RetrofitClient.getInstance()
        var apiInterface = retrofit.create(SimpleApi::class.java)
        lifecycleScope.launchWhenCreated {
            try {
                val response = apiInterface.getPost()
                if (response.isSuccessful) {
                    var json = Gson().toJson(response.body())
                    if (response.body()?.data?.size!! <= 0) {
                        Toast.makeText(
                            this@MainActivity,
                            "No Data ",
                            Toast.LENGTH_LONG
                        ).show()
                    } else {
                        txtData.text = json
                    }

                } else {
                    Toast.makeText(
                        this@MainActivity,
                        response.errorBody().toString(),
                        Toast.LENGTH_LONG
                    ).show()
                }
            }catch (Ex: Exception){
                Log.e("Error",Ex.localizedMessage)
            }
        }

    }

Any Ideas why android studio might be giving me back a 403 error? Many Thanks

CodePudding user response：

The HTTP 403 Forbidden client error status response code indicates that the server understood the request but refuses to authorize it.

This status is similar to 401, but in this case, re-authenticating will make no difference. The access is permanently forbidden and tied to the application logic (like an incorrect password).

CodePudding user response：

i just implement it in some code you can check it below :

 request = new Request.Builder()
                    .url("https://api.johnlewis.com/search/api/rest/v2/catalog/products/search/keyword?q=dishwasher&key=AIzaSyDD_6O5gUgC4tRW5f9kxC0_76XRC8W7_mI")
                    .get()
                    .addHeader("Cache-Control","no-cache")
                    .addHeader("User-Agent",System.getProperty("http.agent"))
                    .build();

by using above code i am able to get 200 response in mobile app. i used OkttpClient for this just add header in retrofit to solve 403 issue.

Response{protocol=h2, code=200, message=, url=https://api.johnlewis.com/search/api/rest/v2/catalog/products/search/keyword?q=dishwasher&key=AIzaSyDD_6O5gUgC4tRW5f9kxC0_76XRC8W7_mI}

Enjoy !!! Happy Coding !!
