     * Validates the FTP request by checking the reply code from the FTP server.
     * If the reply code indicates an error, a CrawlingAccessException is thrown.

使用以下代码创建类实例：

{* ../../docs_src/dependencies/tutorial011.py hl[16] *}

这样就可以**参数化**依赖项，它包含 `checker.fixed_content` 的属性 - `"bar"`。

## 把实例作为依赖项

然后，不要再在 `Depends(checker)` 中使用 `Depends(FixedContentQueryChecker)`， 而是要使用 `checker`，因为依赖项是类实例 - `checker`，不是类。

处理依赖项时，**FastAPI** 以如下方式调用 `checker`：

```Python
checker(q="somequery")
```

……并用*路径操作函数*的参数 `fixed_content_included` 返回依赖项的值：

   * @return this for the builder pattern

  @CanIgnoreReturnValue
  public ThreadFactoryBuilder setPriority(int priority) {
    // Thread#setPriority() already checks for validity. These error messages
    // are nicer though and will fail-fast.
    checkArgument(
        priority >= Thread.MIN_PRIORITY,
        "Thread priority (%s) must be >= %s",
        priority,

    @Test
    void testMatchesVersion() {
        MavenPluginJavaPrerequisiteChecker checker = new MavenPluginJavaPrerequisiteChecker(new GenericVersionScheme());
        assertTrue(checker.matchesVersion("1.0", "1.8"));
        assertTrue(checker.matchesVersion("1.8", "9.0.1+11"));
        assertFalse(checker.matchesVersion("[1.0,2],[3,4]", "2.1"));
        assertTrue(checker.matchesVersion("[1.0,2],[3,4]", "3.1"));

          @Override
          public int size() {
            return AbstractNetwork.this.edges().size();
          }

          // Mostly safe: We check contains(u) before calling successors(u), so we perform unsafe
          // operations only in weird cases like checking for an EndpointPair<ArrayList> in a
          // Network<LinkedList>.
          @SuppressWarnings("unchecked")
          @Override

      Class<? extends Exception> exceptionClass) {
    try {
      Exception unused = newWithCause(exceptionClass, new Exception());
      return true;
    } catch (Throwable t) { // sneaky checked exception
      return false;
    }
  }

  private static <X extends Exception> X newWithCause(Class<X> exceptionClass, Throwable cause) {

They will be checked independently for each *path operation*.
