使用PHP发布嵌套JSON时遇到问题

我正在尝试将一些表单数据作为JSON对象发送到sample app on Force.com。我使用jQuery获取表单数据并将其POST到我的服务器上的PHP文件,然后将其发送到上面链接的示例应用程序。我从示例应用程序得到的响应然而告诉我,我一路上犯了一些错误。

与示例Force.com应用程序对话的PHP文件:

<?php

    $url = 'https://cmsamp.secure.force.com/GenericApp/services/apexrest/GenericApp';
    $data = $_POST[ 'data'];

    $options = array('http' => array('method'  => 'POST','content' => http_build_query($data)));
    $context  = stream_context_create($options);
    $result = file_get_contents($url, false, $context);

    echo $result;

?>

将表单数据发布到PHP文件的客户端jQuery代码:

var sample_form_data = {"attributes":{"type":"Generic_App__c"},"Application_Type__c":"iPay","Return_Email__c":"lsmith@cmsrep.com","Name":"Bus Test","ACHRejectFee__c":"123456789","ApplicationDate__c":"2000-01-01","BusinessPhone__c":"(555) 123-4567","Email__c":"thetest@testemail.com","InternetPercentage2__c":"0","MailingState__c":"CA","MOTO7__c":"true","NumOfLocations__c":"15"};

$.post( url, { data: JSON.stringify( sample_form_data ) }, function( result ) { 
    console.log( result );
});

来自Force.com应用程序的回复:

"No content to map to Object due to end of inputInsert failed. 
First exception on row 0; 
first error: REQUIRED_FIELD_MISSING, 
Required fields are missing: [Name]: [Name]"

期望的“成功”回应:

"Success: 
Generic App Object: Bus Test; was successfully created and inserted"

这是php代码中var_dump($data)的输出(为了可读性添加了换行符:

string(405)
    "{\"attributes\":
        {\"type\":\"Generic_App__c\"},
    \"Application_Type__c\":\"iPay\",
    \"‌​Return_Email__c\":\"lsmith@cmsrep.com\",
    \"Name\":\"Bus Test\",
    \"ACHRejectFee__c\":\"123456789\",
    \"ApplicationDate__c\":\"2000-01-01\",
    \"B‌​usinessPhone__c\":\"(555) 123-4567\",
    \"Email__c\":\"thetest@testemail.com\",
    \"InternetPercentage2__c\":\"0\"‌​,
    \"MailingState__c\":\"CA\",
    \"MOTO7__c\":\"true\",
    \"NumOfLocations__c\":\"15\"
    }" 

通用应用程序只希望获得具有适当字段的JSON对象。当我通过REST客户端提交以下内容时,它按预期工作(同样,为了可读性添加了换行符):

{"attributes":
    {"type":"Generic_App__c"},
"Application_Type__c":"iPay",
"Return_Email‌​__c":"test@example.org",
"Name":"Bus Test",
"ACHRejectFee__c":"123456789",
"ApplicationDate__c":"2000-01-01",
"BusinessPho‌​ne__c":"(555) 123-4567",
"Email__c":"thetest@testemail.com",
"InternetPercentage2__c":"0",
"Mailing‌​State__c":"CA",
"MOTO7__c":"true",
"NumOfLocations__c":"15"} 

任何人都有关于如何解决这个问题的想法?

答案 0 :(得分:2)

从那些var_dumps的外观来看,我要说你需要在使用之前从$ data中删除这些斜杠。试试stripslashes

答案 1 :(得分:0)

http_build_query也需要一个数组。由于您的数据已经是json字符串,我认为您应该省略它。您可能需要对其进行url编码,但您应该只使用常规的urlencode函数。

另外,我不熟悉你正在使用的php上下文机制,我对php.net文档非常不满意,但我无法摆脱这种唠叨的感觉'content' => $data正在做的不仅仅是设置内容。您是否有实际使用'content'选项的流上下文的良好文档链接?
