如何通過電腦或相機在服務器上傳圖像?通過Httppost將圖像上傳到服務器
我嘗試this link的代碼,但它顯示了這樣的
Error:(329, 24) error: cannot access AbstractBody class file for org.apache.james.mime4j.message.AbstractBody not found

您可以上傳圖像到服務器使用http後多部分。這裏是幫助你的鏈接。
還有一方式來上傳圖片,將其轉換爲Base64和比上傳。檢查下面的鏈接。
錯誤,如果你使用異步HTTP作爲你的HTTP客戶端click-here那麼你可以用下面的方法[如果你選擇異步HTTP你可以使用此方法] 此方法不僅可以上傳圖像,還可以用於對服務器進行普通的後調用。
YourFragment.class [這個類中調用http請求]
public class YourFragment extends CommanAbstract
{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View v = inflater.inflate(R.layout.your_layout, container, false);
ButterKnife.inject(this, v);
return v;
}
private void linkCall() {
// TODO Auto-generated method stub
RequestParams params = new RequestParams();
params.put("params1", "value1");
params.put("params2", "value2");
//note that "image" tag will be the tag which accepts the file to the server
params.put("image", new File("your image path from gallery or camera"));
parse(params, 1, your link here, true);
}
@Override
public void parseresult(String response, boolean success, int value) {
// TODO Auto-generated method stub
switch (value) {
case 1:
//here you can parse the link response
break;
}
}
@Override
public void error(String response) {
// TODO Auto-generated method stub
//error will come here
}
}
CommanAbstract類[擴展該類中不斷類,你有一個http請求]
public abstract class CommanAbstract extends Fragment{
private static final String Url = "your link head here";
public abstract void parseresult(String response, boolean success, int value);
public abstract void error(String response);
public void parse(RequestParams params, final int value, String link,
boolean progrss) {
// TODO Auto-generated method
AsyncHttpClient client = new AsyncHttpClient();
GlobalFunctions.postApiCall(getActivity(), link, params, client,
new HttpResponseHandler() {
@Override
public void handle(String response, boolean success) {
// TODO Auto-generated method stub
if (success) {
parseresult(response, true, value);
} else {
error(response);
toast("Connection error");
}
}
});
}
}
GlobalFunctions類[此類呼叫http請求]
public class GlobalFunctions {
// static ProgressDialog progress;
public interface HttpResponseHandler {
void handle(String response,boolean failre);
}
public static void postApiCall(final Context context, final String url,
RequestParams params, AsyncHttpClient httpClient,
final HttpResponseHandler handler) {
httpClient.post(url, params, new AsyncHttpResponseHandler() {
@Override
public void onFailure(Throwable arg0, String failureResponse) {
// TODO Auto-generated method stub
super.onFailure(arg0, failureResponse);
System.out.println("fail" + failureResponse + "url is" + url);
handler.handle(failureResponse,false);
// errorToast(context);
}
@Override
public void onSuccess(String response) {
handler.handle(response,true);
}
});
}
}
