设置 HTTP 调用的请求主体字节。此 API 操作与 HCHttpCallRequestSetRequestBodyReadFunction 互斥，会导致此前在该调用句柄上设置的任何自定义读取回调被忽略。

## 语法

```cpp theme={null}
HRESULT HCHttpCallRequestSetRequestBodyBytes(  
         HCCallHandle call,  
         const uint8_t* requestBodyBytes,  
         uint32_t requestBodySize  
)  
```

### 参数

*call*   \_In\_\
类型：HCCallHandle

HTTP 调用的句柄。

*requestBodyBytes*   \_In\_reads\_bytes\_(requestBodySize)\
类型：uint8\_t\*

HTTP 调用的请求主体字节。

*requestBodySize*   \_In\_\
类型：uint32\_t

所设置主体的字节长度。

### 返回值

类型：HRESULT

此 API 操作的结果代码。可能的值有 S\_OK、E\_INVALIDARG、E\_OUTOFMEMORY 或 E\_FAIL。

## 备注

必须在调用 HCHttpCallPerformAsync 之前调用此函数。
