    ContentResponse response = client.newRequest("localhost", connector.getLocalPort()).scheme(scheme).method(HttpMethod.POST).content(multiPart).send();
    Assert.assertEquals(200, response.getStatus());
    Files.delete(tmpPath);
}

Example 7 with Charset

@Override
public NetSocket write(String str, String enc) {
    synchronized (conn) {
        Charset cs = enc != null ? Charset.forName(enc) : CharsetUtil.UTF_8;
        writeData(Unpooled.copiedBuffer(str, cs), false);
        return this;
    }
}

Example 8 with Charset

use of java.nio.charset.Charset in project tomcat by apache.

the class OutputBuffer method setConverter.

private void setConverter() throws IOException {
    if (coyoteResponse != null) {
        enc = coyoteResponse.getCharacterEncoding();
    }
    if (enc == null) {
        enc = org.apache.coyote.Constants.DEFAULT_CHARACTER_ENCODING;
    }
    final Charset charset = getCharset(enc);
    conv = encoders.get(charset);
    if (conv == null) {
        conv = createConverter(charset);
        encoders.put(charset, conv);
    }
}

Example 9 with Charset

use of java.nio.charset.Charset in project tomcat by apache.

the class ApplicationPushBuilder method decode.

// Package private so it can be tested. charsetName must be in lower case.
static String decode(String input, String charsetName) {
    int start = input.indexOf('%');
    int end = 0;
    // Shortcut
    if (start == -1) {
        return input;
    }
    Charset charset;
    try {
        charset = B2CConverter.getCharsetLower(charsetName);
    } catch (UnsupportedEncodingException uee) {
        // before reaching here
        throw new IllegalStateException(uee);
    }
    StringBuilder result = new StringBuilder(input.length());
    while (start != -1) {
        // Found the start of a %nn sequence. Copy everything form the last
        // end to this start to the output.
        result.append(input.substring(end, start));
        // Advance the end 3 characters: %nn
        end = start + 3;
        while (end < input.length() && input.charAt(end) == '%') {
            end += 3;
        }
        result.append(decode(input.substring(start, end), charset));
        start = input.indexOf('%', end);
    }
    // Append the remaining text
    result.append(input.substring(end));
    return result.toString();
}

@Override
public void writeTo(final Template template, final Viewable viewable, final MediaType mediaType, final MultivaluedMap<String, Object> httpHeaders, final OutputStream out) throws IOException {
    try {
        Object model = viewable.getModel();
        if (!(model instanceof Map)) {
            model = new HashMap<String, Object>() {

                {
                    put("model", viewable.getModel());
                }
