一、参数差别
this.web.loadData(html, "text/html", "utf-8");
this.web.loadDataWithBaseURL("about:blank", html, "text/html", "utf-8", null);
二、loadData需要先转码。
loadData不支持#、%、\、? 四种字符。但也不是完全不支持,表现很怪异。
最好的办法,是用以下方法转码:
final String digits = "0123456789ABCDEF";
public String encode(String s)
{
// Guess a bit bigger for encoded form
StringBuilder buf = new StringBuilder(s.length() + 16);
for (int i = 0; i < s.length(); i++) {
char ch = s.charAt(i);
if ((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z')
|| (ch >= '0' && ch <= '9') || ".-*_".indexOf(ch) > -1) { //$NON-NLS-1$
buf.append(ch);
} else {
byte[] bytes = new String(new char[] { ch }).getBytes();
for (int j = 0; j < bytes.length; j++) {
buf.append('%');
buf.append(digits.charAt((bytes[j] & 0xf0) >> 4));
buf.append(digits.charAt(bytes[j] & 0xf));
}
}
}
return buf.toString();
}
即:
this.web.loadData(this.encode(html), "text/html", "utf-8"); |
