您也可以手动构造请求 XML，并将其发送到 kSOAP 进行发送和响应处理。您可以使用soapUI 编写您的请求XML，然后使用{%key%} 等关键字将它们保存在res/raw 中，其中应在运行时放置参数。
下面是替换关键字的代码：
// parse the template and replace all keywords
StringBuffer sb = new StringBuffer();
try {
// find all keywords
Pattern patern = Pattern.compile("\\{%(.*?)%\\}");
Matcher matcher = patern.matcher(templateHtml);
while (matcher.find()) {
String keyName = matcher.group(1);
String keyValue = values.get(keyName);
if (keyValue == null) {
keyValue = "";
}
// replace the key with value
matcher.appendReplacement(sb, keyValue);
}
matcher.appendTail(sb);
// return the final string
return sb.toString();
} catch (Throwable e) {
Log.e(LOG_TAG, "Error parsing template", e);
return null;
}
要使用 kSOAP 发送自定义 XML 请求，您需要创建自己的传输类。
或者您可以使用DefaultHttpClient（参见Using client/server certificates for two way authentication SSL socket on Android）手动发送请求，并使用kSOAP 来解析响应。
