Android文件上传可用于Form表单提交方式(适用于所有网络框架)

摘要: Android文件上传可用于Form表单提交方式(适用于所有网络框架),可高度解耦

将需要上传的内容转换成HttpEntity,便可适用于所有的网络请求框架

(1)转换成HttpEntity

public static HttpEntity makeMultipartEntity(List<NameValuePair> params, final Map<String, File> files) {
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);  //如果有SocketTimeoutException等情况，可修改这个枚举
//builder.setCharset(Charset.forName("UTF-8")); //不要用这个，会导致服务端接收不到参数
if (params != null && params.size() > 0) {
for (NameValuePair p : params) {
builder.addTextBody(p.getName(), p.getValue(), ContentType.TEXT_PLAIN.withCharset("UTF-8"));
}
}
if (files != null && files.size() > 0) {
Set<Entry<String, File>> entries = files.entrySet();
for (Entry<String, File> entry : entries) {
builder.addPart(entry.getKey(), new FileBody(entry.getValue()));
}
}
return builder.build();
}

(2)使用此HttpEntity 例子使用AQuery进行测试

AQuery aQuery = new AQuery(this);
Map<String, File> files = new HashMap<String, File>();
files.put(path, file);
HttpEntity entity = CommUtil.makeMultipartEntity(null, files);
Map<String, Object> params = new HashMap<String, Object>();
params.put(AQuery.POST_ENTITY, entity);
aQuery.progress(dialog).ajax(CustomURL.POST_API_MEMBER_UPLOADAVATAR, params, JSONObject.class, new AjaxCallback<JSONObject>(){
@Override
public void callback(String url, JSONObject object,
AjaxStatus status) {
// TODO Auto-generated method stub
super.callback(url, object, status);
}
});

用到的两个jar包 : httpcore-4.3.2.jar httpmime-4.3.5.jar
