getCacheKey method

String? getCacheKey(
  1. String? customCacheKey,
  2. RequestOptions? options
)

获取缓存Key，customCacheKey和options必须有一个不为空，否则返回null

Implementation

String? getCacheKey(String? customCacheKey, RequestOptions? options) {
  if (customCacheKey != null) {
    return md5.convert(utf8.encode(customCacheKey)).toString();
  }
  if (options == null) {
    return null;
  }

  String path = options.uri.toString();
  customCacheKey = options.extra[CacheStrategy.CUSTOM_CACHE_KEY];
  StringBuffer stringBuffer = StringBuffer(path);

  options.queryParameters.forEach((key, value) {
    stringBuffer.write("_");
    stringBuffer.write(key);
    stringBuffer.write("_");
    stringBuffer.write(value);
  });

  var body = options.data;
  if (body != null) {
    stringBuffer.write("_");
    stringBuffer.write(
      md5.convert(utf8.encode(jsonEncode(body).toString())).toString(),
    );
  }
  return md5.convert(utf8.encode(stringBuffer.toString())).toString();
}
