android模拟表单提交多数据

移动开发，经常会遇到图片（多图片），视频，录音，文本信息等复杂数据的提交问题，所以可以让android模拟web表单的方法一次行提交所有数据。我封装了一个公共类。直接上代码，下面的代码需要用到xUtils-2.6.14.jar，httpcore-4.3.3.jar，httpmime-4.3.6.jar

//多数据上传操作类

public class MultiUploadOperation {

private Activity activity;

private List<BasicNameValuePair> texts;

private HashMap<File, String> files;

private String url;

private Dialog dialog;

private OnMultiUploadLinister onMultiUploadLinister;

public MultiUploadOperation(Activity activity, String url,List<BasicNameValuePair> texts, HashMap<File, String> files) {

this.activity = activity;

this.texts = texts;

this.files = files;

this.url = url;

}

public void upload(boolean isShowDialog , String msg) {

if(isShowDialog){

//logingview

LogingDialogView dalogView = new LogingDialogView(activity);

dialog = dalogView.createDialog(msg);

dialog.show();

}

HttpEntity httpEntity = initHttpPostData(url, texts, files);

RequestParams params = new RequestParams("UTF-8");

params.setBodyEntity(httpEntity);

HttpUtils http = HttpUtilsHelper.getHttpUtils();

http.send(HttpMethod.POST, url, params, new RequestCallBack<String>() {

@Override

public void onFailure(HttpException arg0, String error) {

if (onMultiUploadLinister != null) {

onMultiUploadLinister.onFailure(error);

}

if (dialog != null) {

dialog.dismiss();

dialog = null;

}

}

@Override

public void onSuccess(ResponseInfo<String> responseInfo) {

String result = responseInfo.result;

if (onMultiUploadLinister != null) {

onMultiUploadLinister.onSuccess(result);

}

if (dialog != null) {

dialog.dismiss();

dialog = null;

}

}

});

}

/**

* 模拟表单 封装表单数据

*

* @return HttpPost

*/

private HttpEntity initHttpPostData(String url, List<BasicNameValuePair> texts, HashMap<File, String> files) {

MultipartEntityBuilder create = MultipartEntityBuilder.create();

//不要用这个会使服务器接收不到数据

//create.setCharset(Charset.forName("UTF-8"));

// 普通文本的发送，用户名&密码等

if (texts != null && texts.size() > 0) {

for (BasicNameValuePair iterable_element : texts) {

create.addTextBody(iterable_element.getName(),iterable_element.getValue() , ContentType.TEXT_PLAIN.withCharset("UTF-8"));

}

}

// 二进制的发送，文件

if (files != null && files.size() > 0) {

Set<Entry<File, String>> entrySet = files.entrySet();

for (Entry<File, String> iterable_element : entrySet) {

create.addBinaryBody(iterable_element.getValue(),iterable_element.getKey());

}

}

HttpEntity httpEntity = create.build();

return httpEntity;

}

public void setOnMultiUploadLinister(

OnMultiUploadLinister onMultiUploadLinister) {

this.onMultiUploadLinister = onMultiUploadLinister;

}

public interface OnMultiUploadLinister {

public void onSuccess(String result);

public void onFailure(String error);

}
