使用 ASIHTTPRequest POST 多部分/表单数据
我是 ASIHTTPRequest 的新手，在实现表单时遇到问题。 目前，我在 UIWebForm 中使用以下代码，一切正常。
NSString *body = @"\
<html> \
<head> \
<meta http-equiv=\"Content-Type\" content=\"text/html;
charset=iso-8859-1\"> \
</head> \
<body>\
<form name=\"my_form\" action=\"http://www.server.com/ar?
ca=11_s&id=22630957\" \
method=\"POST\" enctype=\"multipart/form-data\"> \
<input type=\"text\" name=\"name\" value=\"myname\"> \
<input type=\"text\" name=\"email\" value=\"[email protected]\"> \
<textarea name=\"body\">My message</textarea> \
<input type=checkbox name=\"sendercc\" value=\"0\"> \
<input type=\"submit\" name=\"send\" value=\"Send\"> \
</table> \
</form> \
</body>\
</html>";
应替换表单的（不起作用）代码如下：
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:
[[[NSURL alloc] initWithString:@"http://www.server.com/ar?
ca=11_s&id=22630957"] autorelease]];
[request setResponseEncoding:NSISOLatin1StringEncoding];
[request setPostFormat:ASIMultipartFormDataPostFormat];
[request setPostValue:@"myname" forKey:@"name"];
[request setPostValue:@"[email protected]" forKey:@"email"];
[request setPostValue:@"My message" forKey:@"body"];
[request setPostValue:@"0" forKey:@"sendercc"];
[request startSynchronous];
I'm new to ASIHTTPRequest and I have a problem to implement a form.
At the moment I use the following code inside a UIWebForm and everything work fine.
NSString *body = @"\
<html> \
<head> \
<meta http-equiv=\"Content-Type\" content=\"text/html;
charset=iso-8859-1\"> \
</head> \
<body>\
<form name=\"my_form\" action=\"http://www.server.com/ar?
ca=11_s&id=22630957\" \
method=\"POST\" enctype=\"multipart/form-data\"> \
<input type=\"text\" name=\"name\" value=\"myname\"> \
<input type=\"text\" name=\"email\" value=\"[email protected]\"> \
<textarea name=\"body\">My message</textarea> \
<input type=checkbox name=\"sendercc\" value=\"0\"> \
<input type=\"submit\" name=\"send\" value=\"Send\"> \
</table> \
</form> \
</body>\
</html>";
The (not working) code that should replace the form is the follow:
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:
[[[NSURL alloc] initWithString:@"http://www.server.com/ar?
ca=11_s&id=22630957"] autorelease]];
[request setResponseEncoding:NSISOLatin1StringEncoding];
[request setPostFormat:ASIMultipartFormDataPostFormat];
[request setPostValue:@"myname" forKey:@"name"];
[request setPostValue:@"[email protected]" forKey:@"email"];
[request setPostValue:@"My message" forKey:@"body"];
[request setPostValue:@"0" forKey:@"sendercc"];
[request startSynchronous];

您能详细解释一下它是如何不起作用的吗？如果检查 request.responseString，是否会从服务器返回错误？
您可能需要为提交按钮添加一个值，即：
如果这没有帮助，请尝试使用代理，例如 CharlesProxy< /a> 捕获来自浏览器的工作请求和非工作 iPhone 请求，并比较它们以查找任何差异。
Could you explain more about how it doesn't work? Do you get an error back from the server if you check request.responseString?
You may need to add a value for the submit button, ie:
If that doesn't help, try using a proxy like CharlesProxy to capture both a working request from the browser and the non-working iphone request, and compare them looking for any differences.
