希伯来语在服务器端被视为乱码

发布于 2024-10-31 13:18:18 字数 3462 浏览 3 评论 0原文

我有一个 iPhone 模拟器应用程序作为客户端和 WCF-REST，在 IIS 7.0 服务器上运行的 json 编码服务。我试图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”是要发送到服务器的参数，排序为parameter_name =>参数值。

//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];

我在服务器端收到的请求和响应（通过使用 ethereal 得到的）：

请求：

POST /SmsliMobileService.svc/SetContactGroups HTTP/1.1

I have an iPhone simulator app as client and WCF-REST, json encoded service running on IIS 7.0 server.
I'm trying to send some hebrew characters to the service as parameter and the server return error code 400 - Bad Request.
When I'm sending an English string the server processes the string as it should.

The code used for the string encoding looks like this:

Note that "parameters" is the parameters that about to be sent to the server, ordered as 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];

The request and response I'm getting in the server side (got this by using ethereal):

Request:

Any help will be appreciated.

我发布的代码有错误。

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

此行（最初位于问题的代码中）生成了错误 - 不是采用从“[reqString UTF8String]”返回的字节数组的长度，而是给出了错误的长度 - nsstring 的长度...

修复代码：

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

I had an error on the posted code.

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

This line (was originally in the question's code) generated the error - instead of taking the length of the bytes array returned from: "[reqString UTF8String]", a wrong length had been given - the length of the nsstring...

The fixed code:

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