如何解决AFNetworking中的头问题？

Question

数据在Postman应用程序中运行正常，但无法在代码中运行。以下是代码

  NSString* link = [NSString stringWithFormat:@"http://apifm.azurewebsites.net/token"];

AFHTTPRequestOperationManager* manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:nil];

manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];

[manager.requestSerializer setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];


[manager POST:link parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

    NSMutableData *email = [[NSMutableData alloc] init];
    NSMutableData *password = [[NSMutableData alloc] init];
    NSMutableData *grantType = [[NSMutableData alloc] init];
    [email appendData:[[NSString stringWithFormat:@"testman1@foodmandu.com"] dataUsingEncoding:NSUTF8StringEncoding]];
    [password appendData:[[NSString stringWithFormat:@"testUserPw"] dataUsingEncoding:NSUTF8StringEncoding]];
    [grantType appendData:[[NSString stringWithFormat:@"password"] dataUsingEncoding:NSUTF8StringEncoding]];

    [formData appendPartWithFormData:email name:@"UserName"];
    [formData appendPartWithFormData:password name:@"Password"];
    [formData appendPartWithFormData:grantType name:@"grant_type"];

} success:^(AFHTTPRequestOperation* operation, id responseObject) {





    NSLog(@"success");

} failure:^(AFHTTPRequestOperation* operation, NSError* error){


    [API alertViewWithMessage:[[operation responseObject] objectForKey:@"error"] inController:self];
}];

以下是Postman应用程序的屏幕截图

执行代码时得到的错误在下面给出

  

错误错误Domain = com.alamofire.error.serialization.response Code = -1011“请求失败：错误请求（400）”UserInfo = 0x7faf3b6d6cf0 {com.alamofire.serialization.response.error.response = {URL：{ {3}}} {状态代码：400，headers {       “Cache-Control”=“no-cache”;       “内容长度”= 34;       “Content-Type”=“application / json; charset = UTF-8”;       Date =“Sun，05 Jul 2015 07:11:19 GMT”;       Expires =“ - 1”;       Pragma =“no-cache”;       Server =“Microsoft-IIS / 8.0”;       “Set-Cookie”=“ARRAffinity = ebb02fb6b319b5ae83e167620f3bc3ad6e68d31fb30aff79ef123aabd981588e; Path = /; Domain = apifm.azurewebsites.net”;       “X-Powered-By”=“ASP.NET”;   }，NSErrorFailingURLKey = http://apifm.azurewebsites.net/token，com.alamofire.serialization.response.error.data =＆lt; 7b226572 726f7222 3a22756e 73757070 6f727465 645f6772 616e745f 74797065 227d＆gt;，NSLocalizedDescription =请求失败：错误请求（400）}

提醒您，Postman中的数据工作正常。

Answer 1

您应该将参数作为NSDictionary传递，例如＆＃34; NSDictionary * parameters = @ {@＆＃34; UserName＆＃34;：@＆＃34; testman1@foodmandu.com" ;, @＆＃34;密码＆＃34;：@＆＃34; testUserPw＆＃34;， @＆＃34; grant_type＆＃34;：@＆＃34;密码＆＃34;}; ＆＃34;

这可以使用以下代码实现：

function FBLogin() {
//Fb app information//

window.fbAsyncInit = function() {
    Parse.FacebookUtils.init({
      appId      : 'xxxxxxxxx',
      xfbml      : true,
      version    : 'v2.3'
    });

//rest of function here etc//


}

请尝试以上操作，并告诉我您的反馈意见。
