希伯來語作爲服務器端的垃圾信息

我有一個iPhone模擬器應用程序作爲客戶端和WCF-REST，json編碼服務在IIS 7.0服務器上運行。我試圖發送一些希伯來字符作爲參數的服務和服務器返回錯誤代碼400 - 錯誤的請求。當我發送一個英文字符串時，服務器按照它應該處理的字符串。希伯來語作爲服務器端的垃圾信息

該代碼用於字符串編碼看起來像這樣：

注意，「參數」是將要被髮送到服務器，排序爲PARAMETER_NAME => PARAMETER_VALUE的參數。

//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];

請求和響應我（用空靈得到這個）獲得在服務器端：

請求：

這看起來像一個服務器端的問題給我。該錯誤可能是由服務器程序中的任何異常引發的。在服務器上啓用調試模式，以便您可以在響應中看到完整的異常，或者查看日誌，以查看錯誤是什麼。 – 2011-04-10 09:00:23

我已經發布了原始請求和響應。這不是我們能得到的最好的調試嗎？ – ofirbt 2011-04-10 09:27:59

我在發佈的代碼上有錯誤。

NSData* requestData = [NSData dataWithBytes:[reqString UTF8String] length:[reqString length]];

這條線（原是在問題的代碼）生成的錯誤 - 而不是採取陣列從返回的字節的長度：「[reqString UTF8字符串]」，一個錯誤的長度被給 - 長度的NSString的...

固定代碼：

const char *utf8String = [reqString UTF8String]; // no need to free me - autoreleased object returned. 
NSInteger l = strlen(utf8String); 
NSData *requestData = [NSData dataWithBytes:utf8String length:l];
