問候,Android:上傳照片
我在從我的Android手機上傳照片時遇到問題。下面是我使用提示用戶選擇照片的代碼:
public class Uploader{
public void upload(){
Log.i("EOH","hi...");
Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, 1);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (resultCode == RESULT_OK)
{
Bundle extras = data.getExtras();
Bitmap b = (Bitmap) extras.get("data");
//what do do now with this Bitmap...
//how do I upload it?
}
}
}
所以我有位圖B,但我不知道下一步該怎麼做?
我發送POST請求以下代碼:
List<NameValuePair> params = new ArrayList<NameValuePair>(2);
params.add(new BasicNameValuePair("someValA", String.valueOf(lat)));
params.add(new BasicNameValuePair("someValB", String.valueOf(lng)));
new HttpConnection(handler).post("http://myurl.com/upload.php",params);
我怎麼能一個位圖圖像掛鉤到這一點?我搜索谷歌的年齡,無法找到一個好辦法。
我希望有人能幫忙。
很多感謝,
好吧,我已經試過CHIRAG Shah的建議。這裏是我的代碼:
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (resultCode == RESULT_OK)
{
Uri imageUri=data.getData();
List<NameValuePair> params = new ArrayList<NameValuePair>(1);
params.add(new BasicNameValuePair("image", imageUri.getPath()));
post("http://www.myurl.com/ajax/uploadPhoto.php",params);
}
}
在帖子函數(推薦):
public void post(String url, List<NameValuePair> nameValuePairs) {
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(url);
try {
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
for(int index=0; index < nameValuePairs.size(); index++) {
if(nameValuePairs.get(index).getName().equalsIgnoreCase("image")) {
// If the key equals to "image", we use FileBody to transfer the data
entity.addPart(nameValuePairs.get(index).getName(), new FileBody(new File (nameValuePairs.get(index).getValue())));
}else{
// Normal string data
entity.addPart(nameValuePairs.get(index).getName(), new StringBody(nameValuePairs.get(index).getValue()));
}
}
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost, localContext);
Log.i("EOH",response.toString());
} catch (IOException e) {
e.printStackTrace();
}
}
但是myurl.com/ajax/uploadPhoto.php越來越什麼。我創建了一個PHP日誌來記錄uploadPhoto.php上的任何活動,並且沒有任何內容顯示出來。值得注意的是,如果我只是直接在網頁瀏覽器中輸入myurl.com/ajax/uploadPhoto.php,它會很好地記錄。
還有更多建議嗎?
非常感謝,
我發現所謂的onclick該http帖子必須從異步任務完成,否則他們就不會發生。我一直在尋找類似發佈和獲取數據的東西,並且需要在異步任務中將帖子包裝到url中。 (http://developer.android.com/reference/android/os/AsyncTask.html) – Tim 2013-11-15 00:19:04
