HTTP获取Android Studio API级别23+

Question

Hi! I've been searching around on the Internet for how to make Http Get app in Android Studio, what I found was that you could add

compile group: 'org.apache.httpcomponents', name: 'httpclient', version: '4.5.5'

to the dependencies for Android API level 23>. Or

android{          
    useLibrary  'org.apache.http.legacy'
 }

for Android API level 23+ And then I've been getting the Java code

HttpClient httpClient= HttpClientBuilder.create().build();
HttpGet request= new HttpGet(your_url_to_read);
request.setHeader("k1", "value1");
request.setHeader("k2", "value2");
HttpResponse response= httpClient.execute(request);

System.out.println("Response Code : "+ response.getStatusLine().getStatusCode());
response.getStatusLine().getStatusCode());
//want to read the response content?
BufferedReader rd = new BufferedReader(
        new InputStreamReader(response.getEntity().getContent()));

StringBuffer result = new StringBuffer();
String line = "";
while ((line = rd.readLine()) != null) {
    result.append(line);
}

by @user404. I've successfully been importing the other packages in the Java code below, but on line 1 Android Studio cannot import HttpClientBuilder. Then I came in on a thread about HttpClientBuilder in Android API level 23+ (Which I forget where it was, but it was somewhere on StackOverflow) there someone was saying that you can not import HttpClietBuilder in Android API 23+ because Google removed that feature.

So now I'm looking either for a method to import that HttpClientBuilder package without downgrading the API level or a whole new way to make an Http Get request in Java with headers, like "URL " http://www.something.com/random " HEADERS "Authorization": "123456ABCDEF"" , not parameters in the URL like " http://www.something.com/random?authorization=123456ABCDEF ".

Thanks in forehand for answer

It's just that the org.apache.http packages have been removed by default, so if you target API level 23, you'll need to do something extra to make these work.

Adding useLibrary 'org.apache.http.legacy' to your Gradle is a way to fix this and you'll be able to target 23. However, you'll get the old implementation which is legacy for a reason.

Manually adding the latest version of Apache HttpClient as a dependency is a good choice and will continue to work regardless of which Android version you're targeting.

Likewise, you can use another HTTP library altogether like OkHttp. You can also use a library which is more higher level, like Retrofit.
