POST 方法在 ios 中不起作用

Question

我已经尝试了所有可能的方法来使用 NSURLSession、AFNetworking、NSURLConnection 在 post 方法中发送数据；但每次我的后端开发人员都说他们没有收到任何数据，尽管我的同事 android开发人员正在 POST.I 中成功发送数据，我完全无助 now.Please 求助。

---- 使用 NSURLConnection ----

NSString *post = [NSString stringWithFormat:@"user_id=%@&email=%@",[[NSUserDefaults standardUserDefaults] valueForKey:@"UserId"],emailString];
NSLog(@"------%@-------",post);
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding ];//[post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%lu",(unsigned long)[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@app_user_service/app_invite_email",App_Domain_Url]]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];

if(conn) {
    NSLog(@"Connection Successful");
} else {
    NSLog(@"Connection could not be made");
}

// ---- 使用 AFNetworking ----

NSDictionary *dic2 = @{@"user_id": [[NSUserDefaults standardUserDefaults] valueForKey:@"UserId"] , @"email" : emailString};

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

[manager POST:urlstring parameters:dic2 progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    NSLog(@"success!");



    NSDictionary *dict=[NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingAllowFragments error:nil];
    NSLog(@"Response----> %@",dict);

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    NSLog(@"error: %@", error);
}];

Answer 1

请检查您是否设置属性如下所示

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];

在 iOS9 中，Apple 添加了名为 App Transport Security (ATS) 的新功能。

ATS 在网络调用期间强制执行最佳实践，包括使用 HTTPS。

在你里面添加以下内容info.plist

您可以在 Info.plist:

中为特定域添加例外

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>testdomain.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <true/>
            <key>NSExceptionMinimumTLSVersion</key>
            <string>TLSv1.2</string>
            <key>NSThirdPartyExceptionAllowsInsecureHTTPLoads</key>
            <false/>
            <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
            <true/>
            <key>NSThirdPartyExceptionMinimumTLSVersion</key>
            <string>TLSv1.2</string>
            <key>NSRequiresCertificateTransparency</key>
            <false/>
        </dict>
    </dict>
</dict>
