Answer 1

你可以使用Retrofit2库从Android应用程序的api url中提取数据。

Answer 2

您可以使用OkHTTP库。下面是一个示例代码片段:

OkHttpClient client = new OkHttpClient();
MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");
RequestBody body = RequestBody.create(mediaType, "app_key=whatever");
Request request = new Request.Builder()
.url("https://app.inyek.com/app_api/api_extra/all_order.php")
.post(body)
.addHeader("Content-Type", "application/x-www-form-urlencoded")
.addHeader("key", "whatever")
.addHeader("cache-control", "no-cache")
.addHeader("Postman-Token", "whatever")
.build();
Response response = client.newCall(request).execute();
