ios - 同步 HTTPS POST 请求 iOS

Question

对于 Android，我可以通过以下方式发送 POST 请求:

HttpClient http = new DefaultHttpClient();
HttpPost request = new HttpPost("https://somewebsite.com");
request.setEntity(new StringEntity(data));
http.execute(request);

但是，在 iOS 上我收到以下错误:

NSURLConnection/CFURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9843)

在 iOS 上使用 https 执行同步 POST 请求的最佳方式是什么？

你可以试试这个功能:

-(NSData *)post:(NSString *)postString url:(NSString*)urlString{

    //Response data object
    NSData *returnData = [[NSData alloc]init];

    //Build the Request
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:urlString]];
    [request setHTTPMethod:@"POST"];
    [request setValue:[NSString stringWithFormat:@"%lu", (unsigned long)[postString length]] forHTTPHeaderField:@"Content-length"];
    [request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];

    //Send the Request
    returnData = [NSURLConnection sendSynchronousRequest: request returningResponse: nil error: nil];

    //Get the Result of Request
    NSString *response = [[NSString alloc] initWithBytes:[returnData bytes] length:[returnData length] encoding:NSUTF8StringEncoding];

    bool debug = YES;

    if (debug && response) {
        NSLog(@"Response >>>> %@",response);
    }


    return returnData;
}

下面是你如何使用它:

NSString *postString = [NSString stringWithFormat:@"param=%@",param];
NSString *urlString = @"https://www.yourapi.com";

NSData *returnData =  [self post:postString url:urlString];

编辑:

我在源码中找到错误代码:

errSSLHostNameMismatch = -9843,/* 对端主机名不匹配 */

问题应该出在您的服务器上。

这里来自docs :

errSSLHostNameMismatch -9843 The host name you connected with does not match any of the host names allowed by the certificate. This is commonly caused by an incorrect value for the kCFStreamSSLPeerName property within the dictionary associated with the stream’s kCFStreamPropertySSLSettings key. Available in OS X v10.4 and later.
