我有一个iPhone模拟器应用程序作为客户端和WCF-REST,json编码服务在IIS 7.0服务器上运行。 我正在尝试将一些希伯来字符作为参数发送到服务,服务器返回错误代码400 - 错误请求。 当我发送英文字符串时,服务器按原样处理字符串。
用于字符串编码的代码如下所示:
请注意,“参数”是即将发送到服务器的参数,按parameter_name =>排序。 PARAMETER_VALUE。
//RPC JSON
NSString* reqString = [parameters JSONRepresentation];
//Request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
NSData* requestData = [NSData dataWithBytes:[reqString UTF8String] length:[reqString length]];
//prepare http body
[request setHTTPMethod: @"POST"];
[request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json; charset=UTF-8" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody: requestData];
urlConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];
我在服务器端获得的请求和响应(通过使用ethereal得到这个):
请求:

发布的代码出错了。
NSData* requestData = [NSData dataWithBytes:[reqString UTF8String] length:[reqString length]];
这一行(最初在问题的代码中)生成了错误 - 而不是从以下返回的字节数组的长度:“[reqString UTF8String]”,给出了一个错误的长度 - nsstring的长度..
固定代码:
const char *utf8String = [reqString UTF8String]; // no need to free me - autoreleased object returned.
NSInteger l = strlen(utf8String);
NSData *requestData = [NSData dataWithBytes:utf8String length:l];
