我有一个有2个请求的网站：

首先是要看到装有配料的篮子（无需登录）

GET https://www.ah.nl/mijnlijst2

第二个是将商品插入购物篮的请求。

POST https://www.ah.nl/common/api/basket/v2/add
{
    "items": [{
        "quantity": 1,
        "id": 395948
    }]
}

在我的应用程序中，我已完成3件事：

使用隐藏的网络视图初始化cookie：

initializeWebView(binding.webView, "https://www.ah.nl/mijnlijst2")

var myCookie = ""

@SuppressLint("javascriptInterface", "SetJavaScriptEnabled")
fun initializeWebView(webView: WebView, url: String?) {
    val settings = webView.settings
    settings.javaScriptEnabled = true
    settings.builtInZoomControls = false
    settings.setGeolocationEnabled(true)
    settings.setAppCacheEnabled(false)
    settings.loadsImagesAutomatically = true
    webView.webViewClient = WebViewClient()
    webView.loadUrl(url)

    webView.webViewClient = object : WebViewClient() {

        override fun onPageFinished(webView: WebView?, url: String) {
            super.onPageFinished(webView, url)

            val syncManager =
                CookieSyncManager.createInstance(webView?.context)
            val cookieManager: CookieManager = CookieManager.getInstance()
            cookieManager.setAcceptThirdPartyCookies(webView,true)

            if (cookieManager.getCookie(url)!= null) {
                val cookie: String = cookieManager.getCookie(url)
                myCookie = cookie
                Timber.d("Cookie = $myCookie")
            }

            syncManager.sync()
        }
    }

    webView.loadUrl(url)
}

2：插入成分：

val response = api.insertIngredient(WebViewManager.myCookie, ingredients).execute()

interface AHApi {

    @Headers(
        "content-type: application/json; charset=utf-8",
        "accept-encoding: gzip, deflate, br"
    )
    @POST("common/api/basket/v2/add")
    fun insertIngredient(
        @Header("cookie") cookie: String,
        @Body ingredients: AhIngredientRequest
    ): Call<ResponseBody>
}

data class AhIngredientRequest(

    @Expose
    @SerializedName("items")
    val items: List<AhItem>
)

data class AhItem(

    @SerializedName("id")
    var id: Long = 0L,

    @SerializedName("quantity")
    var quantity: Long = 1L
)

@Provides
@Singleton
fun provideAHApi(context: Context): AHApi{
    val interceptor = HttpLoggingInterceptor()
    if (BuildConfig.DEBUG) {
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY)
    } else {
        interceptor.setLevel(HttpLoggingInterceptor.Level.NONE)
    }

    val timeout = 30L
    val client: OkHttpClient = OkHttpClient.Builder()
        .readTimeout(timeout, TimeUnit.SECONDS)
        .writeTimeout(timeout, TimeUnit.SECONDS)
        .connectTimeout(timeout, TimeUnit.SECONDS)
        .followRedirects(false)
        .build()

    val retrofit: Retrofit = Retrofit.Builder()
        .baseUrl(context.getString(R.string.ah_api))
        .addConverterFactory(MoshiConverterFactory.create().asLenient())
        .client(client)
        .build()
    return retrofit.create(AHApi::class.java)
}

启动Web视图中的项目列表：

class WebviewFragment : Fragment() {

private lateinit var binding: FragmentWebviewBinding

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    val rootView = inflater.inflate(R.layout.fragment_webview, container, false)
    binding = DataBindingUtil.bind(rootView)!!

    WebViewManager.initializeWebView(binding.webView, "https://www.ah.nl/mijnlijst2")

    return rootView
}
}
