ios ASIHttpRequest库进行DELETE操作时delete带有参数表单的使用方法

1，普通的DELETE只需加上下述一句code:

[request setRequestMethod:@"DELETE"];
2，附带有参数表单的情况（一次删除请求）：

    ASIFormDataRequest *request;
    NSURL *baseURL = [NSURL URLWithString:@"http://www.baidu.com/xx/"];
    request = [ASIFormDataRequest  requestWithURL:baseURL];
    

    //header
    [request addRequestHeader:@"Authorization" value:headerforAuthen];
    
    //form
    [request setPostValue:username forKey:@"userpair_name"];
    
    /// Call this before setting request method
    [request buildPostBody];
    
    //构造请求
    [request setRequestMethod:@"DELETE"];
    
    //设置代理
    [request setDelegate:self];
    
    //设置超时
    [request setTimeOutSeconds:10];
    
    //url请求失败处理
    [request setDidFailSelector:@selector(urlRequestFailed_DeleteUserPair:)];
    
    //url请求成功处理
    [request setDidFinishSelector:@selector(urlRequestSuccessed_DeleteUserPair:)];
    
    //异步传输
    [request startAsynchronous];
    return YES;

说明：

现有要提交的数据：

[request setPostValue:username forKey:@"userpair_name"];

只添加

[request setRequestMethod:@"DELETE"];
这行代码并不能正确实现DELETE,

需要添加

    [request buildPostBody];
另外注意 setRequestMethod:@"DELETE"这行要在buildPostBody之后。
