MultipartEntityBuilder和setCharset为UTF-8发送内容为空 [英] MultipartEntityBuilder and setCharset for UTF-8 sends empty content
问题描述
我需要提交UNI code字符形式来定位我的应用程序与非拉丁字母的国家。有一个关于新MultiPartEntityBuiler文档很少,我只发现了另外一个帖子建议使用setCharset。
如果我不使用Entity.setCharset(Consts.UTF_8);变量被转换成????? 当我使用Entity.setCharset(Consts.UTF_8);该变量是空白(空内容)。
下面是低于code。任何想法??

我遇到了同样的问题,发现了这个解决方案。
而不是使用addTextBody使用addPart与StringBody的。
的ContentType的contentType = ContentType.create(HTTP.PLAIN_TEXT_TYPE,HTTP.UTF_8);
StringBody stringBody;
对于(进入<字符串,字符串>的NameValuePair:Data.entrySet()){
stringBody =新StringBody(NameValuePair.getValue(),则contentType);
Entity.addPart(NameValuePair.getKey(),stringBody);
}
反正这解决了这个问题对我来说。希望它能帮助。
I need to submit unicode characters to a form to localize my app to countries with non latin alphabet. There is little documentation about the new MultiPartEntityBuiler and I only found one other post suggesting to use setCharset.
If I don't use Entity.setCharset(Consts.UTF_8); the variables are transformed into "?????" When I use Entity.setCharset(Consts.UTF_8); the variables are blanked (empty content).
Here is the code below. Any idea??

//if (Uploadable == null || !Uploadable.exists())
//return ABORTED;
HttpPost Post = new HttpPost(Url);
MultipartEntityBuilder Entity = MultipartEntityBuilder.create();
// TODO To avoid unicode characters turned unto ??? but if we decomment variables are empty...
//Entity.setCharset(Consts.UTF_8);
if (Data != null && Data.size() > 0)
{
for (Entry<String, String> NameValuePair : Data.entrySet())
Entity.addTextBody(NameValuePair.getKey(), NameValuePair.getValue(), ContentType.TEXT_PLAIN);

I ran into the same problem and found this solution.
Instead of using addTextBody use addPart with a StringBody.
ContentType contentType = ContentType.create(HTTP.PLAIN_TEXT_TYPE, HTTP.UTF_8);
StringBody stringBody;
for (Entry<String, String> NameValuePair : Data.entrySet()){
stringBody = new StringBody(NameValuePair.getValue(), contentType);
Entity.addPart(NameValuePair.getKey(), stringBody);
}
Anyways this solved the issue for me. Hope it helps.
