如何在Apache HTTP Components中设置编码？

Question

How do I set the character encoding in Apache HTTP Components?

I do something like this:

    Form form = Form.form();
    form = form.add("somekey", "somevalue");
    Request request = Request.Post("http://somehost/some-form")
                             .request.bodyForm(form.build());

"somekey" and "somevalue" are unicode strings because all java string are unicode. http components converts them to latin-1 when I tested. I want it to convert to something else (eg, utf-8).

Going by what you've shown in your example, you seem to be using the fluent API.

Looking into the javadocs there is a version of request.bodyForm() that accepts a charset:

    import org.apache.http.Consts;
    ...
    request = request.bodyForm(form.build(), Consts.UTF_8);

According to the source , the charset defaults to Consts.ISO_8859_1 (aka Latin-1).

Alternatives

1. If that doesn't work, consider:

    import org.apache.http.Consts; ... request.elementCharset(Consts.UTF_8); 

2. As a last resort, it should be possible to set the content charset. Looking at the source for elementCharset() , you could try the following:

    import org.apache.http.Consts; import org.apache.http.params.CoreProtocolPNames; ... request.config(CoreProtocolPNames.HTTP_CONTENT_CHARSET, Consts.UTF_8);
