在使用Android studio的时候，需要在 build.gradle(Module:app)中添加 useLibrary'org.apache.http.legacy'
添加位置如：
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
useLibrary'org.apache.http.legacy'
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
compile files('libs/xUtils-2.6.14.jar')
compile files('libs/universal-image-loader-1.9.3.jar')
compile files('libs/gson-2.2.4.jar')
}
//----------------------------------------------------------------------
//HttpUtils实例化对象
HttpUtils http = new HttpUtils();
/*
*发送请求send(HttpMethod method, String url, RequestCallBack<T> callBack)
* method请求方式
* url请求地址
*RequestCallBack <String>请求完后的回调监听String是请求完后你想让他返回什么类型的
*/
http.send(HttpRequest.HttpMethod.GET, urlPath,new RequestCallBack<String>() {
@Override
public void onLoading(long total, long current, boolean isUploading) {
}
@Override
public void onSuccess(ResponseInfo<String> responseInfo) {
String s = responseInfo.result;
System.out.println(s);
}
@Override
public void onStart() {
}
@Override
public void onFailure(HttpException error, String msg) {
}
});
//-----------------eclipse---中-----这么用-----------------------
//创建一个请求方法
private void HttpUtilRequest() {
//创建HttpUtils
HttpUtils httpUtils=new HttpUtils();
//发送GET请求
httpUtils.send(HttpMethod.GET, urlPath, new RequestCallBack<String>() {
@Override//失败
public void onFailure(HttpException arg0, String arg1) {
// TODO Auto-generated method stub
}
@Override//成功
public void onSuccess(ResponseInfo<String> arg0) {
String str=arg0.result;
Log.i("-----++++++-----+++++", str);
Message message=new Message();
message.what=0;
message.obj=str;
handler.sendMessage(message);
}
});
}
