[b]关于httpclient乱码问题我改写了源码
改写的地方
org.apache.commons.httpclient.util.EncodingUtil[/b]

public static byte[] getAsciiBytes(final String data) {

if (data == null) {
throw new IllegalArgumentException("Parameter may not be null");
}

try {
return data.getBytes("UTF-8");
} catch (UnsupportedEncodingException e) {
throw new HttpClientError("HttpClient requires ASCII support");
}
}

[b]org.apache.commons.httpclient.methods.multipart.StringPart[/b]

public StringPart(String name, String value, String charset) {

super(
name,
DEFAULT_CONTENT_TYPE,
charset == null ? "UTF-8" : charset,
DEFAULT_TRANSFER_ENCODING
);
if (value == null) {
throw new IllegalArgumentException("Value may not be null");
}
if (value.indexOf(0) != -1) {
// See RFC 2048, 2.8. "8bit Data"
throw new IllegalArgumentException("NULs may not be present in string parts");
}
this.value = value;
}

[b]org.apache.commons.httpclient.methods.multipart.FilePart[/b]

public FilePart(String name, PartSource partSource, String contentType, String charset) {

super(
name,
contentType == null ? DEFAULT_CONTENT_TYPE : contentType,
charset == null ? "UTF-8" : charset,
DEFAULT_TRANSFER_ENCODING
);

if (partSource == null) {
throw new IllegalArgumentException("Source may not be null");
}
this.source = partSource;
}
