希伯来语作为服务器端的废话
希伯来语作为服务器端的废话
提问于 2011-04-10 16:50:41
我有一个iPhone模拟器应用程序作为客户端和WCF-REST，json编码的服务运行在IIS7.0服务器上。我尝试将一些希伯来语字符作为参数发送给服务，服务器返回错误代码400 - Bad Request。当我发送一个英文字符串时，服务器会按其应有的方式处理该字符串。
用于字符串编码的代码如下所示：
请注意，" parameters“是即将发送到服务器的参数，排序为parameter_name => 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];我在服务器端得到的请求和响应(通过使用ethereal获得)：
请求：

我在发布的代码中有一个错误。
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-而不是获取从"reqString UTF8String“返回的字节数组的长度，给出了错误的长度-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];页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
