我正在尝试对网址进行HTTP发布。
我遵循了这个答案中的代码：
http://stackoverflow.com/questions/2935946/sending-images-using-http-post
所有HttpComponent库已成功包含在我的项目中。
但是，在手机上测试代码时出现此错误：

这是我的代码：
@SuppressWarnings("deprecation")
public class HttpContentPost {
private static final String BASE_URL = "http://example.com/api/index.php";
public static void sendPost(String imagePath, ProductRaw data)
throws IOException, ClientProtocolException {
String responseBody;
HttpClient client = new DefaultHttpClient();
HttpPost request = new HttpPost(BASE_URL);
MultipartEntity entity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
File file = new File(imagePath);
ContentBody encFile = new FileBody(file,"image/jpg");
Log.i("TAG", "BUILDING HTTP ENTITY");
entity.addPart("file", encFile);
entity.addPart("action", new StringBody("publishMarket"));
entity.addPart("email", new StringBody(data.ownerEmail));
entity.addPart("password", new StringBody(data.ownerPasswd));
entity.addPart("title", new StringBody(data.productName));
entity.addPart("description", new StringBody(data.productDesc));
entity.addPart("currency_code", new StringBody(data.productCurrency));
entity.addPart("price", new StringBody(data.productPrice));
entity.addPart("category", new StringBody(data.productCat));
entity.addPart("tag", new StringBody(data.productTag));
request.setEntity(entity);
Log.i("TAG", request.toString());
ResponseHandler<String> responsehandler = new BasicResponseHandler();
responseBody = client.execute(request, responsehandler);
if (responseBody != null && responseBody.length() > 0) {
Log.w("TAG", "Response image upload" + responseBody);
}
}
}
有谁知道我怎么解决这个问题？

我最终做了以下事情：
重启Eclipse
重新添加必需的* jars（项目属性＆gt;库标签＆gt;添加外部JAR
希望这可以在将来帮助你。
