androidokhttp上传⽂件,AndroidStudio上传⽂件实例_OKHTTP 效果(服务器是⾃⼰的，地址⾃⼰找)
image.png
思路
1、添加依赖
implementation 'com.squareup.okhttp3:okhttp:3.11.0'
implementation "com.github.bumptech.glide:glide:4.8.0"
implementation 'fit2:converter-gson:2.4.0'
2、添加权限
⽹络、读写权限。
3、XML布局
xmlns:app="/apk/res-auto"
xmlns:tools="/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
android:id="@+id/upload_bt"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="上传" />
android:id="@+id/upload_tv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@id/upload_bt"
android:gravity="center"
android:text="显⽰⽂本"
android:textSize="18sp" />
android:id="@+id/upload_image"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_below="@id/upload_tv"
郑洞国
android:layout_centerHorizontal="true"
android:scaleType="centerCrop"
android:src="@drawable/ic_launcher_background" />
4、动态权限获取
if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE)==
PackageManager.PERMISSION_GRANTED){
try {
upLodeFile();
} catch (IOException e) {
e.printStackTrace();
}
}el {
}
5、OKHTTP上传⽂件
//创建OK
OkHttpClient okHttpClient = new OkHttpClient.Builder().build();
//请求体
RequestBody requestBody = ate(MediaType.par("image/png"), file);
MultipartBody body = new MultipartBody.Builder()
.tType(MultipartBody.FORM)
.addFormDataPart("key", "1") //post请求Key,value
什么东西补锌
.addFormDataPart("file", Name(),requestBody) //post请求Key,value
.build();
//构建请求
Request request = new Request.Builder()
// .url("yun918/study/public/index.php/file_upload.php")
.url("yun918/study/public/file_upload.php")
.post(body)
.build();
//call对象
Call call = wCall(request);
//call执⾏请求
@Override
public void onFailure(Call call, IOException e) {
Log.e("tag", "onFailure: "+e.getMessage());
}
@Override
public void onRespon(Call call, Respon respon) throws IOException {
String json = respon.body().string();
final UpLoadBean upLoadBean = new Gson().fromJson(json, UpLoadBean.class);
if (!TextUtils.isEmpty(json)){
int code = Code();
String str = String.valueOf(code);
if (str.equals("200")){
元宵节活动报道runOnUiThread(new Runnable() {
@Override
public void run() {
uploadTv.Res());
Glide.with(MainActivity.this).Data().getUrl()).into(uploadImage); }
});
}el {
Toast.makeText(MainActivity.this, "上传失败", Toast.LENGTH_SHORT).show();
}
}
}
});
