MultipartEntityBuilder and Charset

Question

I upgraded my httpmime package, and now my strings are not sent or received as UTF-8

MultipartEntityBuilder entity = MultipartEntityBuilder.create();
Charset chars = Charset.forName("UTF-8");
entity.setCharset(chars);
entity.addTextBody("some_text", some_text);

HttpPost httppost = new HttpPost(url); 
httppost.setEntity(entity.build());
...and so on..

what am I missing? I used to build a StringBody and set the charset in the stringbody, but that is deprecated now, and it just doesn't seem to work

Solution 1

Solved it :) it turns out that ContentType is now important, and I was sending text that was plain, and also some text that was JSON,

for the plain text, you can use:

entity.addTextBody("plain_text",plain_text,ContentType.TEXT_PLAIN);

and for JSON:

entity.addTextBody("json_text",json_text,ContentType.APPLICATION_JSON);

that way the charset also works on JSON strings (weird, but now OK)

Solution 2

entity.addTextBody("plain_text", plain_text);

will use the default ContentType.TEXT_PLAIN which look like this...

public static final ContentType TEXT_PLAIN = ContentType.create("text/plain", Consts.ISO_8859_1);

while ContentType.APPLICATION_JSON is using UTF-8 as below

public static final ContentType APPLICATION_JSON = ContentType.create("application/json", Consts.UTF_8);

So what i did was create our own ContentType like this..

entity.addTextBody("plain_text", plain_text, ContentType.create("text/plain", MIME.UTF8_CHARSET));

Solution 3

For those who say the accepted solution did not work for them (it didn't for me either), I solved it a different way, using:

builder.addTextBody(key, שלום, ContentType.TEXT_PLAIN.withCharset("UTF-8"));

Solution 4

Please try this for

Utf-8:

entity.addTextBody("your text", stringBuffer.toString(), ContentType.create("text/plain", Charset.forName("UTF-8")));

Solution 5

In my case, I setup the contentType first like this

ContentType contentType = ContentType.create(
                        HTTP.PLAIN_TEXT_TYPE, HTTP.UTF_8);

and when adding pairs , specify the content type like this

entityBuilder.addTextBody("title",pic.getTitle(),contentType);

as answered here MultipartEntityBuilder and setCharset for UTF-8 sends empty content

As far as the document page hc.apache.org/httpcomponents-client-ga/httpmime/apidocs/org/‌​…, org.apache.http.entity.ContentType) says, StringBody(String text, ContentType contentType, Charset charset) is not deprecated in 4.3.x

Above Solution didn't worked for me, this did (http*-4.3.6.jar). +1

ContentType.create("text/plain", MIME.UTF8_CHARSET) worked for me. You are my hero.
