# 子应用 - 挂载 { #sub-applications-mounts }

如果需要两个独立的 FastAPI 应用，拥有各自独立的 OpenAPI 与文档，则需设置一个主应用，并**挂载**一个（或多个）子应用。

## 挂载 **FastAPI** 应用 { #mounting-a-fastapi-application }

**挂载**是指在特定路径中添加完全**独立**的应用，然后在该路径下使用*路径操作*声明的子应用处理所有事务。

### 顶层应用 { #top-level-application }

首先，创建主（顶层）**FastAPI** 应用及其*路径操作*：

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[3, 6:8] *}

### 子应用 { #sub-application }

接下来，创建子应用及其*路径操作*。

        assertEquals(SmbComTransaction.TRANS2_QUERY_FS_INFORMATION, cmd.subCommand, "subCommand should be QUERY_FS_INFORMATION");
        // the fields are set in the constructor – check that the counts match
        assertEquals(2, cmd.totalParameterCount, "totalParameterCount should be 2");
        assertEquals(0, cmd.totalDataCount, "totalDataCount should be 0");

     *
     * @param configId the configuration ID to get the pipeline for
     * @return an OptionalThing containing the pipeline string if found, or empty if not found or blank
     */
    public OptionalThing<String> getPipeline(final String configId) {
        final CrawlingConfig config = getCrawlingConfig(configId);
        if (config == null) {

}

func (rl *ReplicationLastMinute) getTotal() AccElem {
	return rl.LastMinute.getTotal()
}

// ReplicationLastHour keeps track of replication counts over the last hour
type ReplicationLastHour struct {
	Totals  [60]AccElem
	LastMin int64
}

// Merge data of two ReplicationLastHour structure

        assertEquals(SmbComTransaction.TRANS_WAIT_NAMED_PIPE, pipe.subCommand);

        // Timeout is set to 0xFFFFFFFF (-1 when cast to int)
        assertEquals(0xFFFFFFFF, pipe.timeout);

        // Max parameter and data counts should be 0
        assertEquals(0, pipe.maxParameterCount);
        assertEquals(0, pipe.maxDataCount);

        // Max setup count should be 0
        assertEquals(0, pipe.maxSetupCount);

# 子應用程式 - 掛載 { #sub-applications-mounts }

若你需要兩個彼此獨立的 FastAPI 應用程式，各自擁有獨立的 OpenAPI 與文件 UI，你可以有一個主應用，並「掛載」一個（或多個）子應用程式。

## 掛載一個 **FastAPI** 應用程式 { #mounting-a-fastapi-application }

「掛載」是指在某個特定路徑下加入一個完全「獨立」的應用程式，之後該應用程式會負責處理該路徑底下的一切，使用該子應用程式中宣告的*路徑操作（path operation）*。

### 頂層應用程式 { #top-level-application }

先建立主（頂層）**FastAPI** 應用程式以及它的*路徑操作*：

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[3, 6:8] *}

### 子應用程式 { #sub-application }
