我正在尝试使用Synapse库在TinyWebDB组件(AppInventor)中存储一个值。我设法使用此代码获取值:
procedure GetValue(Tag:String);
var URL: string;
Params: string;
Response: TMemoryStream;
begin
Response := TMemoryStream.Create;
try
URL := 'http://appinvtinywebdb.appspot.com/getvalue';
Params := 'tag=' + EncodeURLElement(Tag);
if HttpPostURL(URL, Params, Response) then
Response.SaveToFile('response.txt');
finally
Response.Free;
end;
end;
但我无法存储价值。任何想法或建议? 顺便说一句,我尝试通过添加另一个参数并格式化代码来存储值:
procedure StoreValue(Tag, Value: String);
var URL: string;
Params: string;
Response: TMemoryStream;
begin
Response := TMemoryStream.Create;
try
URL := 'http://appinvtinywebdb.appspot.com/storevalue';
Params := 'tag=' + EncodeURLElement(Tag)+'&'+
'value='+ EncodeURLElement(Value);
if HttpPostURL(URL, Params, Response) then
Response.SaveToFile('response.txt');
finally
Response.Free;
end;
end;
它似乎不起作用,因为响应文件为空。它应该包含这样的内容:
[“STORED”,“SomeTag”,“SomeValue”]

我明白了。除了URL之外,第二段代码正在运行。我使用的网址是
而不是
结论:代码完美无缺,结果是[" STORED"," SomeTag"," SomeValue"]。
