Question

Java代码需要在objectiveC中编写一个等价物。

你能帮我解决一下：

JavaCode 网址url;

HttpURLConnection urlConn;
            DataOutputStream printout;
            BufferedReader input;
            url = new URL(IDP_URL);
            urlConn = (HttpURLConnection) url.openConnection();
            urlConn.setDoOutput(true);
            urlConn.setDoInput(true);
            urlConn.setRequestProperty("accept", "application/json");
            urlConn.setRequestMethod("POST");
            // Specify the content type.
            urlConn.setRequestProperty("Content-Type", "text/plain");
            // Send POST output.
            printout = new DataOutputStream(urlConn.getOutputStream());
            String content = "username="
                    + URLEncoder.encode(username, UTF_8_TYPE)
                    + "&password="
                    + URLEncoder.encode(password, UTF_8_TYPE)
                    + "&client_assertion_type="
                    + URLEncoder.encode(tokenType, UTF_8_TYPE)
                    + "&client_assertion="
                    + URLEncoder.encode(appToken, UTF_8_TYPE)
                    + "&spEntityID="
                    + URLEncoder.encode("http://localhost:8080/opensso",
                            UTF_8_TYPE);
            printout.writeBytes(content);
            printout.flush();
            printout.close();
            // Get response data.
            input = new BufferedReader(new InputStreamReader(urlConn
                    .getInputStream()));
            do {
                str = input.readLine();
            } while (str == null);
            input.close();
        } catch (IOException e) {
            LOGGER.error("Exception: ", e);
        }

等效的ios代码：

- (NSString *)urlEncodeValue:(NSString *)str
{

    //            NSString *result = (NSString *) CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)str, NULL, CFSTR(":/?#[]@!$&()*+,;="), kCFStringEncodingUTF8);
    //            return [result autorelease];
    return [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
}

-(void) IdpServiceCall {


    NSString* strRequest = [NSString stringWithFormat:@"username=%@&password=%@&client_assertion_type=%@&client_assertion=%@&spEntityID=%@",
     [self urlEncodeValue:strUsrName],[self urlEncodeValue:strPasswrd],[self urlEncodeValue:@"JWT"],[self urlEncodeValue:strAppTknContent],[self urlEncodeValue:@"http://localhost:8080/opensso"]];
    NSHTTPURLResponse  *response = nil;
    NSError *error = nil;       
    NSURL *nsurl = [[NSURL alloc] initWithString:@"http://10.230.148.253:8080/IDP/services/login/authuser"];  
    NSMutableURLRequest*   urlRequest = [[NSMutableURLRequest alloc] initWithURL:nsurl]; 
        NSData* dataRequest = [NSData dataWithBytes:[strRequest UTF8String] length:[strRequest length]];//this line is for making the nsstring to utf8string and not encoding
        [urlRequest setHTTPMethod: @"POST"];
        [urlRequest setHTTPBody: dataRequest];
    NSString *contentType = [NSString stringWithFormat:@"text/plain"];
    [urlRequest setValue:contentType forHTTPHeaderField:@"Content-Type"];
    [urlRequest setTimeoutInterval:3.0];
    [urlRequest setCachePolicy:NSUrl];    

    NSData *responseData =[NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&error];

NSString *result =[[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];   
        NSLog(@"downloaded idp output  %@",result);     
}

我没有得到所需的输出0字节。

请发现我的问题。真是太棒了。

您的代码看起来很好，只有HTTP Body的NSData看起来很奇怪尝试建立更像这样的数据：

    appToken = [prefs objectForKey:@"Applicasa appToken"];
    [data appendData:[[NSString stringWithFormat:@"%@=%@",@"Key",@"Value"] dataUsingEncoding:NSUTF8StringEncoding]];
    [_request setHTTPBody:data];

如果您为它工作，请告诉我
