当我使用utf-8特殊字符(例如“Ö”)向我的网络服务发送请求时,它会返回响应500“处理请求时出错”这是我在iOS应用程序中登录的内容。< / p>
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSError *error = nil;
dict = [[CJSONDeserializer deserializer] deserializeAsDictionary:self.responseData error:&error];
for (id key in dict) {
NSLog(@"%@=%@", key, [dict objectForKey:key]);
}
如果我发送的信息只是简单的英语,那就可以了。
我不确定错误是在服务器端还是在应用程序本身。 这就是我发送JSON POST的方式:
- (void)stringWithUrl:(NSURL *)url jsonReq:(NSString *)json{
self.requestURL = [[[NSMutableURLRequest alloc] initWithURL:url] autorelease];
self.responseData = [NSData dataWithBytes:[json UTF8String] length:[json length]];
[self.requestURL setHTTPMethod:@"POST"];
[self.requestURL setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[self.requestURL setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[self.requestURL setValue:@"application/json" forHTTPHeaderField:@"UTF-8"];
[self.requestURL setValue:[NSString stringWithFormat:@"%d", [self.responseData length]] forHTTPHeaderField:@"Content-Length"];
[self.requestURL setHTTPBody: self.responseData];
这就是网络服务的外观:
....
[WebService(Namespace = "http://mypage.com/webservicesF")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX,
[System.Web.Script.Services.ScriptService]
.....
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]

在发送之前尝试编码,如:
NSString *strEncode = [src stringByAddingPercentEscapesUsingEncoding:NSUnicodeStringEncoding];

这一行:
self.responseData = [NSData dataWithBytes:[json UTF8String] length:[json length]];
不正确。 NSString
的长度为UTF-16字符,而不是UTF-8字符。你可以这样做:
const char* utf8 = [json UTF8String];
self.responseData = [NSData dataWithBytes:utf8 length:strlen(utf8)];
但更好的方法是让字符串直接创建NSData
,而不通过C风格的字符串。
self.responseData = [json dataUsingEncoding:NSUTF8StringEncoding];
