blogger via idHTTP：错误400错误请求

Question

我试图使用idHTTP组件发布到Blogger，但是，我收到“HTTP/1.0 400错误请求”错误。在

memo1.Text := IdHTTP1.Post('https://www.blogger.com/feeds/' + blogid + '/posts/default', req); 

procedure TForm1.Button1Click(Sender: TObject); 
var request,response,req : TStringlist; 
    auth,blogid : string; 
begin 
blogid := '00000000000000000000000'; 
request := TStringList.Create; 
response := TStringList.Create; 
req  := TStringList.Create; 

IdHTTP1.Request.Connection := 'Keep-Alive'; 
IdHTTP1.Request.ContentType := 'application/x-www-form-urlencoded'; 
IdSSLIOHandlerSocket1.SSLOptions.Method := sslvSSLv23; 

request.Clear(); 
request.Values['accountType'] := 'GOOGLE'; 
request.Values['Email']  := 'xxx@gmail.com'; 
request.Values['Passwd']  := 'yyy'; 
request.Values['service']  := 'blogger'; 

response.Text :=IdHTTP1.Post('https://www.google.com/accounts/ClientLogin',request); 
auth := response.Values['Auth']; //working perfectly 

req.Clear(); 
req.Text := Memo2.Lines.Text; //put entry into request var 

IdHTTP1.Request.CustomHeaders.Clear(); 
IdHTTP1.Request.CustomHeaders.Add('GData-Version: 2'); 
//IdHTTP1.Request.CustomHeaders.Add('Authorization: GoogleLogin auth='+auth); 
IdHTTP1.Request.CustomHeaders.Values['Authorization'] := 'GoogleLogin auth = '+auth; 
IdHTTP1.Request.ContentType := 'application/atom+xml'; 

memo1.Text := IdHTTP1.Post('https://www.blogger.com/feeds/' + blogid + '/posts/default', req); // I got "HTTP/1.0 400 Bad Request" error right here. 

end; 

GOR错误有谁知道我做错了吗？

任何帮助，非常感谢。谢谢！

您正在使用TStringList发布您的XML数据。即使您没有将Request.ContentType设置为application/x-www-form-urlencoded，发布TStrings对象也会像您一样对数据进行编码。这可能是服务器抱怨的原因，因为它不会正确地接收你想要的XML。要发布的XML数据，你需要使用一个TStream代替，例如：

procedure TForm1.Button1Click(Sender: TObject); 
var 
    request, response : TStringlist; 
    req : TStream; 
    auth, blogid : String; 
begin 
    blogid := '00000000000000000000000'; 

    IdHTTP1.Request.Connection := 'Keep-Alive'; 
    IdSSLIOHandlerSocket1.SSLOptions.Method := sslvSSLv23; 

    request := TStringList.Create; 
    try 
    response := TStringList.Create; 
    try 
     request.Values['accountType'] := 'GOOGLE'; 
     request.Values['Email']  := 'xxx@gmail.com'; 
     request.Values['Passwd']  := 'yyy'; 
     request.Values['service']  := 'blogger'; 

     IdHTTP1.Request.ContentType := 'application/x-www-form-urlencoded'; 
     response.Text := IdHTTP1.Post('https://www.google.com/accounts/ClientLogin', request); 

     auth := response.Values['Auth']; 
    finally 
     response.Free; 
    end; 
    finally 
    request.Free; 
    end; 

    req := TMemoryStream.Create; 
    try 
    Memo2.Lines.SaveToStream(req); 
    req.Position := 0; 

    IdHTTP1.Request.CustomHeaders.Clear; 
    IdHTTP1.Request.CustomHeaders.Values['GData-Version'] := '2'; 
    IdHTTP1.Request.CustomHeaders.Values['Authorization'] := 'GoogleLogin auth = ' + auth; 
    IdHTTP1.Request.ContentType := 'application/atom+xml'; 

    Memo1.Text := IdHTTP1.Post('https://www.blogger.com/feeds/' + blogid + '/posts/default', req); 
    finally 
    req.Free; 
    end; 
end;
